feat: comprehensive tool system improvements and webfetch support (#3)

Browse Source 
* feat: enhanced tool instructions for multi-step operations

- Add comprehensive examples for ls, find, grep, mkdir, npm init, etc.
- Explain multi-step workflow (explore → read → write)
- Tool system already supports chaining via conversation history
- Bash tool supports: ls, find, grep, cat, mkdir, cd, npm, etc.
- 30 second timeout on commands
- Output limited to 3000 chars for readability

* Cleanup: Consolidate documentation and tidy codebase

Documentation:
- Consolidate 6 markdown files into simplified README.md
- Remove redundant docs: TODO.md, NETWORK.md, REVIEW.md, PLAN.md, CONTEXT.md, GUIDE.md
- Add ARCHITECTURE.md with clean technical overview
- README now focuses on quick start and core concepts

Code verification:
- Verified blocking I/O properly wrapped in asyncio.to_thread()
- Confirmed locks initialized correctly in backends
- AMD VRAM detection uses proper regex (takes max value, not first match)
- All exception handling uses 'except Exception:' (not bare except)

Tool execution improvements (existing changes):
- Better working directory handling with project root detection
- Extended timeouts for package managers (300s)
- Multi-tool call parsing support
- Improved error handling and logging

Note: System prompt concern noted - 30k tokens too large for 16-32k context windows

* docs: add development patterns analysis

Document circular development issues identified in commit history:
- Tool execution went back-and-forth 3+ times (server-side vs client-side)
- Tool instructions changed from 40k → 300 → removed → enhanced tokens
- 8+ parsing fixes for same issues (no tests)
- 6 debug-only commits (production debugging)

Provides recommendations to prevent future cycles:
1. Pick one architecture and stick with it
2. Add unit tests before fixes
3. Token budget (<2000 for instructions)
4. One format only (remove alternative parsers)
5. Integration test script
6. Separate concerns into smaller modules
7. Design doc before code changes
8. CI/CD with automated testing

* docs: add comprehensive agent guidelines

AGENT_WORKER.md (600+ lines):
- Pre-flight checklist: token budget, test plan, design doc
- Coding rules: TDD, no debug code, architecture consistency
- Git workflow: branching strategy, commit rules, release process
- Testing requirements: unit (≥80%), integration structure
- Code quality: PEP 8, type hints, max 50 lines per function
- Architecture: no feature flags, separation of concerns
- Continuous learning: research requirements, documentation
- Forbidden patterns: bare except, production debugging, etc.

AGENT_REVIEW.md (400+ lines):
- Review philosophy: prevent circular development
- 6-phase review checklist: structure, quality, tokens, architecture, research, logic
- Report format with token impact analysis
- Severity levels: blocking vs warnings vs approved
- Common issues with examples (good vs bad)
- Review workflow: 30-35 min per PR
- Reports stored in reports/ folder (gitignored)

Also added:
- tests/test_tool_parsing.py - example test following guidelines
- Updated DEVELOPMENT_PATTERNS.md with recommendations

Reports folder in .gitignore for local review storage

* chore: gitignore review reports folder

* feat: fix tool execution and enhance instructions with accurate token counting

- Enhanced tool instructions (1041 tokens, within 2000 budget)
- Added tiktoken>=0.5.0 for accurate token counting
- Fixed subprocess hang by adding stdin=subprocess.DEVNULL
- Removed 9 DEBUG print statements from routes.py
- Added tests for instruction content and token budget verification
- All tests pass (11/11)

Resolves blockers from previous review:
- Token budget verified ✓
- Token documentation added ✓
- Debug code cleaned ✓
- Missing tests added ✓

* feat: implement comprehensive tool system with proper logging

Major improvements to tool instructions and execution:
- Enhanced tool instructions with 7-step task completion workflow
- Added markdown code block fallback parser for tool calls
- Fixed subprocess hang with stdin=subprocess.DEVNULL
- Fixed streaming path to return tool_calls (enabling multi-turn conversations)
- Added complete React project creation example with verification steps
- Token count: 1,743 tokens (within 2,000 limit)

Logging infrastructure:
- Created centralized logging configuration (src/utils/logging_config.py)
- Replaced 80+ print statements with logger.debug()
- Set log level to DEBUG for development
- All modules now use proper logging instead of print

Testing:
- Added 4 new tests for markdown parsing and instruction content
- All 13 tests passing
- Token budget verification test

Documentation:
- Added comprehensive design docs for all major changes
- Added test plans for verification
- Created helper scripts for logging migration

Files changed:
- main.py: Added logging setup
- src/api/routes.py: Tool instructions, streaming fixes, logging
- src/tools/executor.py: subprocess fix, logging
- src/utils/: New logging configuration module
- tests/test_tool_parsing.py: New tests
- docs/: Design decisions and test plans
- scripts/: Helper scripts for development

* refactor: simplify tool instructions to 109 tokens for 7B model

Reduced from 1,743 tokens to 109 tokens (94% reduction) to help
qwen2.5 7B 4bit model follow instructions better.

Changes:
- Removed complex workflow documentation
- Removed multi-turn conversation examples
- Removed lengthy anti-patterns
- Kept only essential format and rules
- Updated tests to match simplified content

Before: 1,743 tokens, 6,004 chars (87% of budget)
After: 109 tokens, 392 chars (5.5% of budget)

This should make it much easier for smaller models to:
1. Understand they must use tools
2. Follow the simple TOOL: format
3. Not get overwhelmed by instructions

* refactor: make tool instructions ultra-direct for 7B models

Further simplify instructions to prevent model from adding explanations.

Before: 109 tokens - model still added explanatory text
After: 86 tokens - ultra-direct commands

Key changes:
- Start with 'You MUST use tools. DO NOT explain.'
- 'OUTPUT THIS EXACT FORMAT - NOTHING ELSE'
- Removed all examples and pleasantries
- Added 'NEVER' rules in all caps
- 'ONLY output TOOL: lines'

The model was outputting:
'1. First, install... TOOL: bash ARGUMENTS: {...}'

Now should output just:
'TOOL: bash
ARGUMENTS: {...}'

This should force the 7B qwen model to stop explaining and just execute.

* refactor: move tool instructions to external config file

Moves hardcoded tool instructions from routes.py to external config file
for better maintainability and easier editing.

Changes:
- Created config/prompts/tool_instructions.txt
- Added _load_tool_instructions() function with caching
- Falls back to default if config file not found
- Updated tests to use the loader function
- Added proper error handling

Benefits:
- Easier to modify instructions without code changes
- Instructions can be edited by non-developers
- Cleaner separation of config vs code
- Supports hot-reloading (cached but easy to invalidate)

Token count: 86 tokens (loaded from file)
Location: config/prompts/tool_instructions.txt

* refactor: simplify tool instructions further and add debug logging

- Reduced instructions to bare minimum: 50 tokens
- Added debug logging to verify instructions are sent
- Removed all caps and aggressive language
- Made instructions more straightforward

Instructions now:
'Use tools to execute commands. Output only tool calls.
Format: TOOL: bash ARGUMENTS: {...}
No explanations. No numbered lists. No markdown. Only tool calls.'

This should be easier for 7B models to follow while still
conveying the essential requirements.

* feat: improve tool parser to handle 7B model output variations

Enhanced parse_tool_calls() with multiple fallback strategies:

1. Standard TOOL:/ARGUMENTS: format (original)
2. Markdown code blocks ()
3. Numbered list items (1. npm install ...)
4. Standalone bash commands (npm, npx, mkdir, etc.)

Now handles messy output from small models like:
'1. Install: npm install -g create-react-app'
'2. Create: create-react-app hello-world'

Parses these into chained bash commands for execution.

Also simplified instructions to 50 tokens minimum:
'Use tools to execute commands. Output only tool calls.
Format: TOOL: bash ARGUMENTS: {...}
No explanations. No numbered lists. No markdown. Only tool calls.'

This combination should make 7B models much more likely to
have their output successfully parsed and executed.

* fix: improve command extraction for 7B model output

Parser now extracts bash commands from any line containing:
- npm, npx, mkdir, cd, ls, cat, echo, git, python, pip, node, yarn
- create-react-app (added for React projects)

Example: Extracts 'npm install -g create-react-app' from:
'1. Install: npm install -g create-react-app'

Chains multiple commands with && for sequential execution.

This should now successfully parse the numbered list output
from 7B models and execute the commands.

* feat: add bash tool description validation and improve 7B model parsing

Changes:
- Added _ensure_tool_arguments() function to inject 'description' field
- Updated tool_instructions.txt to require description for bash tool
- Improved 7B model command extraction with better regex patterns
- Added 'create-react-app' to command detection list
- Updated delta field type to Dict[str, Any] for streaming
- Added GGUF to MLX quantization mapping for registry.py
- Clarified agent responsibilities in AGENT_REVIEW.md and AGENT_WORKER.md

Fixes:
- Bash tool now validates required 'description' field
- 7B model output parsed more reliably (numbered lists)
- Multiple commands chained with && for sequential execution

Token count: 69 tokens (down from 86, -19.8%)

All tests pass: 13/13

* feat: add webfetch tool support with URL extraction

Changes:
- Added webfetch to tool instructions config
- Added URL extraction pattern to parse_tool_calls()
- Parser now recognizes URLs and creates webfetch tool calls
- Updated token count: 89 tokens (+29% from 69)

The webfetch tool is available through opencode environment.
System prompt adjustment enables model to use it for URL fetching.

Token budget: 89 tokens (4.45% of 2000 limit)
Tests pass: 13/13

# Agent Reviewer Rules
> **⚠️ IMPORTANT:** This document is for REVIEW AGENTS who handle commits, PRs, and code reviews.
> Regular agents follow AGENT_WORKER.md for implementation tasks and DO NOT make commits.
## Review Philosophy
**Mission:** Prevent the circular development patterns identified in commit history.
**Standards:**
- Reject code that doesn't meet quality bar
- Ask for tests, don't accept "I'll add them later"
- Check token counts for prompt changes
- Verify architectural consistency
- Demand clear error messages
**Reviewer Authority:**
- Can block PR for: missing tests, token bloat, architecture violations
- Cannot approve own code
- Must provide constructive feedback with specific fixes
## Review Checklist
### Phase 1: Structure & Hygiene (Block if failed)

## Severity Levels
### 🔴 BLOCKING (Cannot merge)
- Missing tests for new functionality
- Token budget exceeded
- Bare `except:` clauses
- Production debugging code (`print` statements)
- Breaking changes without documentation
- Security vulnerabilities
- Tests failing
- Type check errors
- Architecture violations
### 🟡 CHANGES_REQUESTED (Fix before merge)
- Unclear variable names
- Missing docstrings
- Inefficient algorithms
- Missing error handling
- Unclear commit messages
- Minor style issues
### 🟢 APPROVED (Optional suggestions)
- Style preferences
- Future improvements
- Optional refactors
## Common Issues to Watch For
### Issue 1: Tool Parsing Duplication
```python
# ❌ WRONG - Multiple parsers
def parse_tools_v1(text): ...
def parse_tools_v2(text): ...
def parse_tools_legacy(text): ...
# ✅ CORRECT - Single parser
TOOL_PATTERN = r'TOOL:\s*(\w+)\s*\nARGUMENTS:\s*(\{[^}]*\})'
```
**Check:** Search for "def parse" - should be ONE per format.
### Issue 2: Token Bloat
```python
# ❌ WRONG - Too verbose
SYSTEM_PROMPT = """
You are an AI assistant. Here are detailed instructions...
[2000 words of explanation]
[10 examples]
"""
# ✅ CORRECT - Concise
SYSTEM_PROMPT = """Use TOOL: name\nARGUMENTS: {...} format. Available: read, write, bash."""
```
**Check:** Count tokens, verify < 2000.
### Issue 3: Architecture Drift
```python
# ❌ WRONG - Mixing concerns in one file
# src/api/routes.py
def handle_request(): ...
def parse_tools(): ...
def execute_tool(): ...
def format_response(): ...
# ✅ CORRECT - Separated
# src/api/routes.py - only HTTP handling
# src/tools/parser.py - only parsing
# src/tools/executor.py - only execution
```
**Check:** Each module has ONE responsibility.
### Issue 4: Debug Code Left In
```python
# ❌ WRONG
def process(data):
print(f"DEBUG: data={data}") # REMOVE THIS
result = transform(data)
print(f"DEBUG: result={result}") # REMOVE THIS
return result
# ✅ CORRECT
logger = logging.getLogger(__name__)
def process(data):
logger.debug("Processing data", extra={"data_size": len(data)})
return transform(data)
```
**Check:** `grep -r "print(" src/ --include="*.py" | grep -v "^#"`
### Issue 5: Missing Error Context
```python
# ❌ WRONG
raise ValueError("Invalid input")
# ✅ CORRECT
raise ValueError(f"Invalid model format: '{model_str}'. Expected: 'name:size:quant' (e.g., 'qwen:7b:q4')")
```
**Check:** All errors explain what was expected vs received.
## Review Workflow
1. **First Pass: Structure** (5 min)
- Check branch name, commits, no debug code
- If failed → Write report, BLOCK
2. **Second Pass: Quality** (10 min)
- Run tests, check types, review code
- If failed → Write report, CHANGES_REQUESTED
3. **Third Pass: Deep Dive** (15 min)
- Read logic, check edge cases
- Verify token counts
- Check architecture
- Write detailed report
4. **Final Decision** (5 min)
- APPROVE / CHANGES_REQUESTED / BLOCK
- Write report to `reports/` folder
- Post summary in PR comments
**Total time per review: 30-35 minutes**
## Reviewer Self-Check
Before submitting review:
- [ ] I ran all tests locally
- [ ] I checked type hints
- [ ] I counted tokens (if applicable)
- [ ] I read every line of changed code
- [ ] My feedback is specific and actionable
- [ ] I explained WHY for each blocker
- [ ] I wrote a report to `reports/` folder
## Escalation
Escalate to architecture discussion if:
- PR changes core patterns
- Token budget cannot be met
- Two reviewers disagree
- Breaking changes proposed
**Don't just approve to be nice.**
**Don't let technical debt accumulate.**
## Report Storage
All reports go in `reports/` folder:
```
reports/
├── PR-123-fix-tool-parsing.md
├── PR-124-add-federation.md
├── PR-125-refactor-consensus.md
└── README.md # Index of all reviews
```
**This folder is gitignored - reports stay local.**
Generate index with:
```bash
ls -1 reports/PR-*.md | sort -t'-' -k2 -n > reports/README.md
```
---
**Remember: You're the last line of defense against technical debt. Be thorough, be kind, be strict.**

# Agent Worker Rules
> **⚠️ IMPORTANT:** This document is for IMPLEMENTATION AGENTS (coding, testing, documentation).
> **DO NOT MAKE COMMITS** - that's the AGENT_REVIEW.md agent's job.
## Pre-Flight Checklist (MUST complete before coding)
### ⚠️ GIT OPERATIONS REMINDER
**DO NOT make commits.** Commits are ONLY handled by AGENT_REVIEW.md agents.
You CAN create branches and stage files (git add), but DO NOT commit (git commit).
### 1. Token Budget Verification
- [ ] System prompt + instructions ≤ 2000 tokens (hard limit)
- [ ] Leave ≥ 50% of context window for user input
- [ ] If adding documentation/examples, remove old ones to maintain budget
- [ ] Use `tiktoken` or estimate: ~4 chars = 1 token
### 2. Test Plan Required
Before writing ANY code, write a test plan:
```markdown
## Test Plan for [Feature]
### Unit Tests
- [ ] Test case 1: [specific input] → [expected output]
- [ ] Test case 2: [edge case]
- [ ] Test case 3: [error condition]
### Integration Tests
- [ ] End-to-end flow: [steps]
- [ ] Expected result: [what success looks like]
### Manual Verification
- [ ] Command to run: [exact command]
- [ ] Expected output: [what to see]
```
### 3. Design Decision Document
For any change > 50 lines:
```markdown
## Design Decision
### Problem
[What are we solving?]
### Options Considered
1. [Option A] - Pros: ..., Cons: ...
2. [Option B] - Pros: ..., Cons: ...
### Decision
[Which option and WHY]
### Impact
- Token count change: [+/- X tokens]
- Breaking changes: [Yes/No]
- Migration needed: [Yes/No]
```
## Coding Rules
### Rule 1: One Feature = One Commit
**NOTE:** Regular agents DO NOT make commits. AGENT_REVIEW.md agents handle commits.
When AGENT_REVIEW.md agents make commits:
- Never combine unrelated changes in one commit
- If you fix a bug AND refactor, make 2 commits
- Commit message format: `type(scope): description`
- Types: `feat`, `fix`, `refactor`, `test`, `docs`, `chore`
- Example: `feat(tools): add working directory support`
### Rule 2: Tests First (TDD)
```python
# BAD: Write code, maybe test later
def parse_tools(text):
# ... implementation ...
pass
# GOOD: Write test first
def test_parse_simple_tool():
text = 'TOOL: read\nARGUMENTS: {"filePath": "test.txt"}'
content, tools = parse_tool_calls(text)
assert len(tools) == 1
assert tools[0]["function"]["name"] == "read"
# Then write minimal code to pass
```
### Rule 3: No Production Debugging
- NEVER add `print()` statements for debugging
- Use `logging` module with appropriate levels
- Remove ALL debug logging before committing
- Exception: Structured logging for observability (metrics, errors)
```python
# BAD
def process_request(request):
print(f"DEBUG: Got request {request}") # REMOVE THIS
result = handle(request)
print(f"DEBUG: Result {result}") # REMOVE THIS
return result
# GOOD
def process_request(request):
logger.debug("Processing request", extra={"request_id": request.id})
result = handle(request)
return result
```
### Rule 4: Architecture Consistency
- Check ARCHITECTURE.md before changing patterns
- If unsure, ask in PR description
- NEVER change architecture in a "fix" commit
- Architecture changes require design doc + team review
### Rule 5: Parse Once, Parse Well
- ONE parser per format
- If adding new format, remove old one
- Parser must handle all documented cases
- Parser must fail gracefully (return empty, not crash)
```python
# BAD: Multiple parsers for same thing
def parse_tools_v1(text): ...
def parse_tools_v2(text): ...
def parse_tools_legacy(text): ...
# GOOD: Single parser with clear regex
TOOL_PATTERN = r'TOOL:\s*(\w+)\s*\nARGUMENTS:\s*(\{[^}]*\})'
def parse_tool_calls(text: str) -> Tuple[str, List[dict]]:
matches = list(re.finditer(TOOL_PATTERN, text, re.IGNORECASE))
if not matches:
return text, []
# ... rest of parsing ...
```
### Rule 6: Token-Aware Documentation
- Every docstring/example has a token cost
- Count tokens before adding
- If over budget, remove something else
- Prioritize: Code clarity > Examples > Explanations
```python
# BAD: 150 tokens of fluff
def calculate(x, y):
"""
This function calculates the sum of two numbers.
The sum is calculated by using the built-in Python
addition operator which adds the values together.
Args:
x (int): The first number to add
y (int): The second number to add
Returns:
int: The sum of x and y
Example:
>>> calculate(1, 2)
3
"""
return x + y
# GOOD: 20 tokens, clear enough
def calculate(x: int, y: int) -> int:
"""Return sum of x and y."""
return x + y
```
### Rule 7: Clear Error Messages
- Every error must tell user EXACTLY what went wrong
- Include context: what was expected vs what was received
- Suggest fix if possible
```python
# BAD
raise ValueError("Invalid input")
# GOOD
raise ValueError(f"Invalid model format: '{model_str}'. Expected: 'name:size:quant' (e.g., 'qwen:7b:q4')")
```
### Rule 8: No Circular Imports
```python
# BAD: src/a.py imports src/b.py, src/b.py imports src/a.py
# GOOD: Use dependency injection or move shared code to common module
```
## Git Workflow Rules
### CRITICAL: Commit Handling
**REGULAR AGENTS: DO NOT MAKE COMMITS**
- Regular agents do NOT create commits, pull requests, or manage git history
- Commits are ONLY handled by agents following AGENT_REVIEW.md guidelines
- If you need to commit code, the AGENT_REVIEW.md agent should handle it
- Exception: You may manually stage files (git add) for the review agent
- **You CAN create and checkout branches** (that's fine) - just don't commit to them
### Branch Strategy
**Main Branches (Protected):**
- `main` - Production-ready code only
- `develop` - Integration branch for features (optional for small projects)
**Working Branches (Temporary - AGENT_REVIEW.md ONLY):**
```
feature/description # New features
fix/description # Bug fixes
refactor/description # Code refactoring
hotfix/description # Critical production fixes
docs/description # Documentation only
experiment/description # Experimental work (may be deleted)
```
**Note:** Regular agents should NOT create branches or handle git operations
### Workflow Steps
#### 1. Starting New Work
```bash
# ALWAYS start from main
git checkout main
git pull origin main
# Create feature branch
git checkout -b feature/description
# Push branch to remote immediately
git push -u origin feature/description
```
#### 2. During Development
```bash
# Commit often (small, logical commits)
git add -p # Stage interactively (review each change)
git commit -m "feat(scope): description"
# Push regularly (backup)
git push origin feature/description
# Keep up-to-date with main
git fetch origin
git rebase origin/main # Resolve conflicts immediately
```
#### 3. Before PR (Final Cleanup)
```bash
# Interactive rebase to clean history
git rebase -i main
# Squash these:
# - "fix typo"
# - "WIP"
# - "asdf"
# - "omg finally"
# - Multiple attempts at same fix
# Keep separate:
# - Logical feature steps
# - Refactoring separate from features
# - Test additions separate from code changes
```
#### 4. Creating PR
- Push final branch: `git push origin feature/description`
- Create PR to `main` (not develop unless project uses git-flow)
- Fill PR template completely
- Request review from AGENT_REVIEW.md qualified reviewer
- Link related issues: `Closes #123`, `Fixes #456`
### Commit Rules
**Commit Frequency:**
- Commit after each logical step (not just at end of day)
- Each commit should leave codebase in working state
- "Work in progress" commits OK on feature branches (clean before PR)
**Commit Size:**
- Max 200 lines changed per commit
- Max 5 files changed per commit (unless related)
- Each commit reviewable in 5 minutes
- Split large changes:
```bash
# BAD: One giant commit
git commit -am "Add federation + fix bugs + refactor + docs"
# GOOD: Separate commits
git commit -m "refactor(network): extract peer discovery logic"
git commit -m "feat(federation): implement cross-swarm voting"
git commit -m "fix(federation): handle peer timeout edge case"
git commit -m "docs: update federation architecture docs"
```
**Commit Message Format:**
```
type(scope): subject (50 chars or less)
Body (wrap at 72 chars):
- Why this change was made
- What problem it solves
- Any breaking changes or migration notes
Refs: #123, #456
```
**Types:**
- `feat`: New feature
- `fix`: Bug fix
- `refactor`: Code restructuring (no behavior change)
- `test`: Adding/updating tests
- `docs`: Documentation only
- `chore`: Build, dependencies, tooling
- `perf`: Performance improvement
- `style`: Formatting (no code change)
**Subject Rules:**
- Use imperative mood: "Add feature" not "Added feature"
- No period at end
- Lowercase after type
- Max 50 characters
### Branch Hygiene
**DO:**
- Create branch from latest main
- Use descriptive branch names
- Push branch to remote immediately
- Rebase onto main regularly
- Delete merged branches
- Squash fixup commits before PR
**DON'T:**
- Commit directly to main
- Have long-lived branches (>1 week without rebase)
- Include unrelated changes in one branch
- Commit broken code (even temporarily)
- Force push to shared branches
- Merge without review
### Handling Conflicts
```bash
# While rebasing
git rebase main
# Conflicts happen...
# Resolve conflicts in files
git add <resolved-files>
git rebase --continue
# If messed up, abort
git rebase --abort
```
**Conflict Resolution Rules:**
1. Understand both changes before resolving
2. Don't just pick "ours" or "theirs"
3. Test after resolving
4. Commit message should explain resolution
### Emergency Procedures
**Committed to wrong branch:**
```bash
# Undo last commit (keep changes)
git reset HEAD~1
# Stash changes
git stash
# Switch to correct branch
git checkout correct-branch
# Apply changes
git stash pop
# Commit properly
git commit -m "..."
```
**Need to undo pushed commit:**
```bash
# Revert (creates new commit, safe for shared history)
git revert <commit-hash>
git push origin branch-name
# OR if feature branch not shared yet
# Reset and force push (DANGEROUS)
git reset --hard HEAD~1
git push --force-with-lease origin branch-name
```
### Release Process
**NOTE:** Release process should be handled by AGENT_REVIEW.md agents.
```bash
# Create release branch
git checkout -b release/v1.2.0
# Bump version, update changelog
git commit -m "chore: bump version to 1.2.0"
# Tag release
git tag -a v1.2.0 -m "Release version 1.2.0"
git push origin v1.2.0
# Merge to main
git checkout main
git merge --no-ff release/v1.2.0
git push origin main
# Delete release branch
git branch -d release/v1.2.0
```
### What Regular Agents Should NOT Do
**REGULAR AGENTS DO NOT:**
- Make commits (git commit)
- Create pull requests
- Push to remote repositories
- Merge branches
- Manage git history (rebase, reset, etc.)
- Delete branches
**REGULAR AGENTS CAN:**
- Create and checkout branches (git checkout -b)
- Stage files for review (git add)
- Switch between branches
**REGULAR AGENTS SHOULD:**
- Write code and tests
- Run tests locally
- Use logging instead of print()
- Follow code quality standards
- Document changes in code comments or design docs
- Hand off completed work to AGENT_REVIEW.md agent for commit/PR creation
**Example Workflow:**
```
1. Agent reads task from user
2. Agent creates feature branch (git checkout -b feature/name)
3. Agent implements feature (writes code, tests, docs)
4. Agent stages changes for review (git add)
5. Agent reports completion with summary of changes
6. AGENT_REVIEW.md agent:
- Reviews code quality
- Makes commits
- Creates PR
```
### Pre-Commit Checklist
- [ ] Code passes `pytest` (if tests exist)
- [ ] No `print()` statements (use logging)
- [ ] No bare `except:` clauses
- [ ] All functions have type hints
- [ ] All public functions have docstrings
- [ ] No TODO comments (create issues instead)
- [ ] Token count checked (if modifying prompts)
## Testing Requirements
### Unit Test Coverage
Minimum 80% coverage for:
- Parsing functions
- Business logic
- State machines
### Integration Tests Required For:
- API endpoints
- Tool execution
- File operations
- Network calls (mocked)
### Test File Structure
```
tests/
├── unit/
│ ├── test_parser.py
│ ├── test_executor.py
│ └── test_consensus.py
├── integration/
│ ├── test_api.py
│ └── test_tools.py
└── fixtures/
└── sample_responses.json
```
## Code Quality Standards
### Python Style
- Follow PEP 8
- Use type hints for all function signatures
- Max line length: 100 characters
- Max function length: 50 lines
- Max file length: 300 lines (split if larger)
### Imports (Order Matters)
```python
# 1. Standard library
import os
import sys
from typing import List
# 2. Third party
import numpy as np
from fastapi import APIRouter
# 3. Local (absolute imports only)
from src.tools.executor import ToolExecutor
from src.swarm.manager import SwarmManager
```
### Documentation Standards
Every module must have:
```python
"""Module purpose in one line.
Longer description if needed (2-3 sentences max).
"""
```
Every public function must have:
```python
def process_data(data: dict, options: Optional[dict] = None) -> Result:
"""Process data with given options.
Args:
data: Input data to process
options: Processing options (default: None)
Returns:
Processed result
Raises:
ValueError: If data is invalid
"""
```
## Architecture Rules
### No Feature Flags in Core Logic
```python
# BAD
if config.get("USE_NEW_PARSER", False):
result = new_parser(text)
else:
result = old_parser(text)
# GOOD: Pick one, remove the other
def parse_tool_calls(text: str) -> Tuple[str, List[dict]]:
"""Parse tool calls from text."""
# Single implementation
```
### No Code Duplication
- If you copy-paste > 3 lines, extract to function
- Shared code goes in `src/common/` or `src/utils/`
### Separation of Concerns
```
src/
├── parser/ # Only parsing logic
├── executor/ # Only execution logic
├── formatter/ # Only formatting/output
└── integration/ # Only API glue code
```
## Forbidden Patterns
### Never Do These:
1. **Bare except clauses** - Always catch specific exceptions
2. **Production debugging** - No `print()`, use logging
3. **Multiple return formats** - One function = one return type
4. **Silent failures** - Always log/report errors
5. **Magic numbers** - Use named constants
6. **Global state** - Use dependency injection
7. **Deep nesting** - Max 3 levels of indentation
8. **Circular dependencies** - Re-architect if needed
## Review Preparation
Before marking PR ready:
1. **Self-Review Checklist** (check each item):
- [ ] Tests pass: `pytest -v`
- [ ] Type checking: `mypy src/`
- [ ] Linting: `ruff check src/`
- [ ] Formatting: `black src/`
- [ ] Token count verified (if applicable)
- [ ] No debug code left in
- [ ] Commit messages follow format
- [ ] Documentation updated
2. **PR Description Template**:
```markdown
## Changes
- [Brief description]
## Testing
- [How you tested it]
## Token Impact (if applicable)
- Before: X tokens
- After: Y tokens
- Change: +/- Z tokens
## Checklist
- [ ] Tests added/updated
- [ ] Documentation updated
- [ ] Self-review completed
```
3. **Run Final Verification**:
```bash
# Run all checks
pytest && mypy src/ && ruff check src/ && black --check src/
```
## Continuous Learning & Research
You MUST periodically research best practices and alternative implementations. This prevents stagnation and ensures we're using proven approaches.
### When to Research
**Before Major Features:**
- Spend 15-30 minutes researching similar implementations
- Check: GitHub, Stack Overflow, official docs, research papers
- Document findings in PR description
**Monthly Reviews:**
- Review project's core technologies for updates
- Check if better libraries/algorithms exist
- Look for deprecated patterns we're using
**When Stuck:**
- Don't brute force a solution
- Research how others solved similar problems
- Consider if problem indicates architectural issue
### What to Research
**1. Best Practices**
```bash
# Search queries to use:
"python async best practices 2024"
"fastapi error handling patterns"
"LLM consensus voting algorithms"
"gguf quantization comparison"
```
**2. Similar Implementations**
- Search GitHub for similar projects
- Read their architecture decisions
- Check their issues for pitfalls they hit
- Note: Don't copy code blindly, understand WHY
**3. Research Papers & Benchmarks**
- For consensus algorithms
- For quantization strategies
- For context window optimization
- For distributed systems patterns
**4. Library Updates**
- Check CHANGELOG of major dependencies
- Review migration guides
- Test new features in separate branch
### Documentation of Research
Create `research/YYYY-MM-DD-topic.md` for significant findings:
```markdown
# Research: [Topic]
**Date:** YYYY-MM-DD
**Researcher:** [Name]
**Trigger:** [Why researched this]
## Findings
### Option 1: [Name]
- Source: [Link]
- Pros: ...
- Cons: ...
- Complexity: Low/Medium/High
### Option 2: [Name]
- Source: [Link]
- Pros: ...
- Cons: ...
- Complexity: Low/Medium/High
## Recommendation
[Which option and WHY]
## Implementation Notes
[Specific code changes needed]
## Risks
[What could go wrong]
```
### Research Checklist
**Before implementing:**
- [ ] Searched for similar open-source implementations
- [ ] Checked recent best practices (2023+)
- [ ] Looked for benchmarking data if applicable
- [ ] Reviewed alternative approaches
- [ ] Considered long-term maintenance implications
**After implementing:**
- [ ] Documented why chosen approach was selected
- [ ] Added comments linking to research sources
- [ ] Created test comparing against alternatives (if applicable)
### Example Research Topics
**Immediate:**
- "Python type hints best practices 2024"
- "FastAPI dependency injection patterns"
- "LLM tool use format comparison"
**Short-term:**
- "Consensus algorithms for distributed LLM systems"
- "Context window compression techniques"
- "GGUF quantization vs other formats"
**Long-term:**
- "Speculative decoding implementation"
- "PagedAttention for multiple workers"
- "RAG integration patterns"
### Research Sources
**Reliable:**
- Official documentation (Python, FastAPI, etc.)
- Well-maintained GitHub repos (>1k stars, active)
- Recent conference talks (PyCon, NeurIPS, etc.)
- Research papers with code (Papers With Code)
- Official blogs (Python.org, FastAPI.tiangolo.com)
**Use with Caution:**
- Medium articles (variable quality)
- Old Stack Overflow answers (>2 years)
- Tutorial sites (often outdated)
- YouTube videos (hard to verify)
### Integration with Development
**Weekly:**
- Spend 30 minutes reading about one technology we use
- Note any improvements we could make
- Create issues for promising findings
**Monthly:**
- Review all open research issues
- Prioritize based on impact vs effort
- Schedule implementation of high-value items
**Quarterly:**
- Architecture review: Are our patterns still best?
- Dependency audit: Updates needed?
- Performance review: Could we be faster?
---
**Remember:**
- Research prevents reinvention of the wheel
- But don't research forever - timebox it (30 min max for most decisions)
- Document findings so others don't repeat the research
- Apply critical thinking - "best practice" depends on context
---
## Breaking This Ruleset
If you MUST break a rule:
1. Document WHY in code comments
2. Get explicit approval in PR
3. Create follow-up issue to fix properly
4. Never break Rule 3 (No Production Debugging)
---
**Remember: Quality over speed. A fix that takes 2 days with tests is better than a fix that takes 2 hours and breaks 3 other things.**

# Network Federation Status
## Overview
Local Swarm has a federation system designed to allow multiple instances to collaborate on the same network, enabling distributed consensus and load balancing across multiple machines.
## Current Implementation Status
### ✅ What's Working
#### 1. Network Discovery (`src/network/discovery.py`)
**Purpose**: Automatic discovery of other Local Swarm instances on the local network using mDNS/Bonjour.
**Key Components**:
- `SwarmDiscovery` class - Main discovery service
- `PeerInfo` dataclass - Stores information about peer swarms
- `start_advertising()` - Announces this swarm to the network
- `start_discovery()` - Listens for other swarms on the network
- `create_discovery_service()` - Factory function to create discovery instance
**How It Works**:
- Uses mDNS service type: `_local-swarm._tcp.local.`
- Advertises on port 63323 (discovery) + API port (17615)
- Broadcasts: version, instances, model_id, hardware_summary
- Peers timeout after 60 seconds if not seen
#### 2. Federation Client (`src/network/federation.py`)
**Purpose**: Communication protocol between peer swarms.
**Key Components**:
- `FederationClient` class - HTTP client for peer communication
- `FederatedSwarm` class - Wraps local swarm with federation logic
- `request_vote()` - Gets generation results from peers
- `generate_with_federation()` - Coordinates distributed generation
- Federation strategies: `best_of_n`, `weighted_vote`, `first_valid`
**API Endpoints** (not yet exposed):
- `POST /v1/federation/vote` - Request generation from peer
- `GET /v1/federation/health` - Check peer health
#### 3. Network Binding (`main.py`)
**Purpose**: Secure local network access without internet exposure.
**Implementation**:
- `get_local_ip()` - Detects local network IP (192.x.x.x or 100.x.x.x)
- Binds to specific local IP instead of 0.0.0.0
- Falls back to localhost if not on private network
## ❌ What's Missing
### Critical Gap: No Integration
**The federation system exists as standalone modules but is NOT connected to the main application flow.**
**Specific Issues**:
1. **No CLI Flag**: No `--federation` or `--enable-federation` argument in `main.py`
2. **Discovery Never Starts**:
- `SwarmDiscovery` class is imported in `network/__init__.py`
- But never instantiated or started in `main.py`
- `start_advertising()` and `start_discovery()` are never called
3. **Federation Never Starts**:
- `FederatedSwarm` class exists but is never instantiated
- `main.py` calls `swarm.generate()` directly
- Should call `federated_swarm.generate_with_federation()` when enabled
4. **API Routes Not Registered**:
- Federation endpoints exist in `federation.py` but aren't added to FastAPI router
- Routes in `src/api/routes.py` don't include `/v1/federation/*`
5. **No Peer Management UI**:
- No way to see discovered peers
- No status dashboard for federation
- No manual peer configuration
## File Structure
```
src/network/
├── __init__.py # Exports SwarmDiscovery, FederationClient, etc.
├── discovery.py # mDNS/Bonjour discovery service
│ ├── SwarmDiscovery # Main discovery class
│ ├── PeerInfo # Peer information dataclass
│ └── create_discovery_service() # Factory function
├── federation.py # Inter-swarm communication
│ ├── FederationClient # HTTP client for peers
│ ├── FederatedSwarm # Wraps swarm with federation
│ ├── PeerVote # Vote from peer
│ └── FederationResult # Result of federated generation
└── (routes missing) # Should add federation routes
main.py # Should integrate federation here
└── Currently: Just runs local swarm
└── Should: Optionally run federated swarm with discovery
```
## Scope
### In Scope
- Automatic discovery of peers on same local network
- Distributed generation across multiple machines
- Consensus voting between local and peer responses
- Health checking and peer timeout handling
- Secure local network binding (no internet exposure)
### Out of Scope (Future)
- Internet-wide federation (would need authentication/encryption)
- Cross-platform federation (Mac ↔ Linux ↔ Windows)
- Peer authentication/authorization
- Encrypted peer communication
- WAN federation through NAT traversal
- Peer reputation/scoring system
## TODO
### Phase 1: Basic Integration (Minimum Viable)
1. **Add `--federation` CLI flag** to `main.py`
- Add argument parser entry
- Conditionally enable federation
2. **Integrate discovery in main flow**
```python
# In main.py after swarm initialization:
if args.federation:
discovery = await create_discovery_service(args.port)
await discovery.start_advertising(swarm_info)
await discovery.start_discovery()
```
3. **Add federation API routes** to `src/api/routes.py`
- `POST /v1/federation/vote`
- `GET /v1/federation/health`
- `GET /v1/federation/peers` (list discovered peers)
4. **Create FederatedSwarm wrapper**
```python
# Replace: result = await swarm.generate(...)
# With:
if args.federation:
federated = FederatedSwarm(swarm, discovery)
result = await federated.generate_with_federation(...)
else:
result = await swarm.generate(...)
```
### Phase 2: Polish
5. **Add peer status display**
- Show discovered peers in startup banner
- Display peer count in status
- Log when peers join/leave
6. **Handle edge cases**
- No peers available (fallback to local only)
- All peers timeout (graceful degradation)
- Split-brain scenarios
7. **Configuration**
- Config file support for federation settings
- Manual peer list (bypass discovery)
- Federation strategy selection
### Phase 3: Testing
8. **Integration tests**
- Two instances on same machine
- Two instances on same network
- Peer timeout handling
- Consensus validation
## Usage (When Complete)
### Start Federated Mode
```bash
# On Mac 1 (192.168.1.100)
python main.py --auto --federation
# On Mac 2 (192.168.1.101)
python main.py --auto --federation
# Both will:
# 1. Start local API on 192.168.x.x:17615
# 2. Advertise via mDNS
# 3. Discover each other within 5-10 seconds
# 4. Distribute generation requests between them
```
### Expected Behavior
1. Both Macs advertise themselves via mDNS
2. Each discovers the other within 10 seconds
3. When a request comes in, both generate responses
4. Consensus algorithm picks best response
5. Result returned to client
## Benefits When Complete
- **More workers**: Combine instances across machines
- **Better consensus**: More responses = better selection
- **Load balancing**: Distribute generation across devices
- **Redundancy**: If one fails, others continue
- **Heterogeneous hardware**: Mix Macs, PCs, servers
## Current Workaround
Until federation is integrated, you can:
1. Run instances independently on different machines
2. Point clients to specific instances manually
3. No automatic peer discovery or coordination

"api_key": "not-needed", "api_key": "not-needed",
"model": "local-swarm" "model": "local-swarm"
} }
} }
``` ```
#### MCP Server (Optional) ## Network Federation (Hive Mind)
For tighter integration with AI assistants, enable the MCP server: Run on multiple machines to combine their power:
```bash ```bash
python main.py --mcp # Machine 1 (Windows with RTX 4060)
python main.py --auto --federation
# Machine 2 (Mac Mini M1)
python main.py --auto --federation
# Machine 3 (Old laptop)
python main.py --auto --federation
``` ```
This runs alongside the HTTP API and exposes tools AI assistants can use: Machines auto-discover each other and vote together on every request.
- `get_hardware_info` - Query CPU, GPU, and RAM
- `get_swarm_status` - Check worker health
- `generate_code` - Generate code with consensus
- `list_available_models` - See what models can run
- `get_worker_details` - Get detailed worker statistics
MCP allows AI assistants to automatically query your hardware capabilities and select appropriate models. ## How Consensus Works
1. Your prompt goes to all LLM instances
2. Each instance generates a response independently
3. The consensus algorithm picks the best answer:
- **Similarity** (default): Groups responses by meaning, picks the largest group
- **Quality**: Scores on completeness, code blocks, structure
- **Fastest**: Returns the quickest response
- **Majority**: Simple text match voting

## How It Works
### Hardware Detection
The tool automatically detects your system:
- **Windows**: NVIDIA (NVML), AMD (ROCm), Intel (OneAPI)
- **macOS**: Apple Silicon via Metal, unified memory model
- **Linux**: NVIDIA (NVML), AMD (ROCm), Intel (OneAPI/OpenCL)
- **Android**: Qualcomm Adreno GPUs (via Termux)
**Supported Backends**:
- **NVIDIA**: CUDA via llama.cpp
- **AMD**: ROCm via llama.cpp (Linux, Windows experimental)
- **Intel**: OneAPI/SYCL via llama.cpp
- **Apple Silicon**: Metal via MLX
- **Qualcomm**: CPU fallback on llama.cpp (Android/Termux)
### Model Selection
Based on available memory:
1. **External GPU**: Use 100% of VRAM minus OS overhead
2. **Apple Silicon**: Use 50% of unified RAM
3. **CPU-only**: Use 50% of system RAM
The algorithm selects:
- Largest model size that fits
- Highest quantization quality possible
- Maximum instances (2-8) based on memory
Example configurations:
| Hardware | Model | Quant | Instances | Memory Used |
|----------|-------|-------|-----------|-------------|
| RTX 4090 24GB | Qwen 2.5 14B | Q4_K_M | 2 | ~17.6 GB |
| RTX 4060 Ti 16GB | Qwen 2.5 7B | Q4_K_M | 3 | ~13.5 GB |
| RTX 4060 Ti 8GB | Qwen 2.5 3B | Q6_K | 4 | ~10.4 GB |
| RX 7900 XTX 24GB | Qwen 2.5 14B | Q4_K_M | 2 | ~17.6 GB |
| Arc A770 16GB | Qwen 2.5 7B | Q5_K_M | 2 | ~10.4 GB |
| M4 Max 64GB | Qwen 2.5 14B | Q4_K_M | 4 | ~35.2 GB |
| M3 Pro 36GB | Qwen 2.5 7B | Q4_K_M | 4 | ~18 GB |
| M1 8GB | Qwen 2.5 3B | Q4_K_M | 2 | ~3.6 GB |
| Snapdragon 8 Gen 3 | Qwen 2.5 3B | Q4_K_M | 1 | ~1.8 GB |
| CPU 32GB | Qwen 2.5 3B | Q4_K_M | 8 | ~14.4 GB |
| **Federated (3 machines)** | **Qwen 2.5 7B** | **Q4_K_M** | **9** | **~40.5 GB** |
### Swarm Consensus
For each request, the swarm:
1. Sends the prompt to all running instances
2. Collects responses in parallel
3. Runs consensus algorithm:
- **Similarity**: Groups responses by semantic similarity, returns largest group
- **Quality**: Scores responses on completeness and code quality
- **Fastest**: Returns the quickest response
4. Returns the winning response via OpenAI-compatible API
### Network Federation
Run Local Swarm on multiple machines in the same network to create a "federated swarm":
**Example Setup**:
- Windows PC (RTX 4060 Ti): 4 instances
- Mac Mini (M1): 2 instances
- MacBook (M4): 3 instances
- Total: 9 instances voting on every request
**How it works**:
1. Each machine auto-discovers others via mDNS/Bonjour
2. Each swarm generates responses independently
3. Local consensus picks best response per machine
4. Cross-swarm consensus votes across all machines
5. Best response returned to client
**To enable federation**:
```yaml
federation:
enabled: true
discovery_port: 8765 # mDNS/Bonjour discovery
federation_port: 8766 # Inter-swarm communication
```
Machines will automatically discover each other within 10 seconds.

## Troubleshooting ## Troubleshooting
### Out of Memory ### Out of Memory
If you get OOM errors:
```bash ```bash
# Reduce instances python main.py --instances 2 # Reduce workers
python -m local_swarm --instances 2 python main.py --model qwen:3b:q4 # Use smaller model
# Or use smaller model
python -m local_swarm --model qwen2.5-coder:3b:q4
``` ```
### Slow Performance ### Slow Performance
- Check GPU utilization with `nvidia-smi` (NVIDIA) or Activity Monitor (macOS) - Check GPU utilization with `nvidia-smi`
- Ensure model is cached (first run downloads to `~/.local_swarm/models`) - Reduce instances to avoid contention
- Try reducing instances to avoid contention - Use Q4 quantization instead of Q6
### Windows: CUDA not detected ### CUDA Not Detected (Windows)
Make sure NVIDIA drivers are installed:
```powershell ```powershell
nvidia-smi nvidia-smi # Check drivers
pip uninstall llama-cpp-python
pip install llama-cpp-python --extra-index-url https://abetlen.github.io/llama-cpp-python/whl/cu121
``` ```
If this fails, reinstall drivers from nvidia.com
### macOS: MLX not found ### macOS: MLX Not Found
```bash ```bash
pip install mlx-lm pip install mlx-lm
``` ```
### Linux: AMD GPU not detected ## Project Structure
Ensure ROCm is installed:
```bash
rocm-smi
```
If not found, install from https://www.amd.com/en/developer/rocm-hub.html
### Linux: Intel GPU not detected
Install Intel oneAPI:
```bash
# Ubuntu/Debian
wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB | sudo gpg --dearmor -o /usr/share/keyrings/intel-oneapi-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/intel-oneapi-archive-keyring.gpg] https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/oneAPI.list
sudo apt update
sudo apt install intel-basekit
```
### Android: Termux issues
- Ensure Termux is installed from F-Droid (not Play Store)
- Run `pkg update` before installation
- Limited to small models (1-3B) due to RAM constraints
- Use CPU backend only (no GPU acceleration on Android yet)
## Requirements
- Python 3.9+
- 4GB+ RAM (8GB+ recommended)
- Optional: NVIDIA/AMD/Intel GPU with 4GB+ VRAM
- Optional: Apple Silicon Mac
- Optional: Android device with 8GB+ RAM (via Termux)

Here's a comprehensive review of your project. It's well-architected overall, but there are several issues worth addressing.
---
Critical Bugs
1. src/network/discovery.py:128 — asyncio.create_task() called from a non-asyncio thread
Zeroconf's ServiceBrowser invokes _on_service_state_change from a background thread, but asyncio.create_task() requires the asyncio event loop in
the current thread. This will crash with RuntimeError: no current event loop. Use asyncio.run_coroutine_threadsafe(coro, loop) instead.
2. src/network/discovery.py:161 — int() on bytes raises TypeError
int(properties.get(b"instances", b"0")) — in Python 3, int(b"0") is a TypeError. Need .decode() first.
3. src/hardware/detector.py:149,174 — Android/Qualcomm detection is unreachable
platform.system() returns "Linux" on Android, not "android". So the code enters the Linux branch, tries NVIDIA/AMD/Intel, fails, and returns None —
never reaching Qualcomm detection.
4. src/api/routes.py:77 — response_model breaks streaming
The route declares response_model=ChatCompletionResponse, but when request.stream=True, it returns a StreamingResponse. FastAPI will try to
validate the streaming response against the Pydantic model and fail.
---
High Severity
5. src/backends/llamacpp.py:85-94 and src/backends/mlx.py:88-96 — Blocking calls in async methods
Both backends call synchronous inference (self._llm(...), mlx_generate(...)) directly inside async def methods. This blocks the entire event loop,
freezing the API server during inference. Wrap in await asyncio.to_thread(...).
6. src/backends/llamacpp.py:29 — Lock declared but never initialized
self._lock = None is never replaced with an actual asyncio.Lock(), so there's no concurrency protection when multiple requests hit the same backend
instance.
7. src/swarm/consensus.py:85,89 — Blocking I/O in async context
SentenceTransformer('all-MiniLM-L6-v2') downloads/loads a model synchronously, and .encode() is CPU-bound. Both freeze the event loop.
8. src/hardware/amd.py:80 — VRAM regex matches wrong number
re.search(r'(\d+)', line) on a line like GPU[0] : VRAM Total Memory (B): 17179869184 matches 0 (from GPU[0]), not the VRAM value.
9. src/models/downloader.py:79-88 — Partial downloads cached as valid
If a download is interrupted, the partial file remains. is_model_cached() sees size > 0 and treats it as valid. Should download to a .tmp file and
rename atomically on completion.
10. src/network/federation.py:253-277 — best_of_n strategy is non-functional
The code creates GenerationResponse objects but never uses them, then just returns the local response. This strategy is dead code.
---
Medium Severity
11. src/models/selector.py:182-184 — Memory calculation uses wrong instance count
total_memory_gb = smallest_quant.vram_gb * instances uses the pre-clamped value, but instances gets max(instances, 1) on the next line. Data
inconsistency.
12. src/models/selector.py:65 — calculate_max_instances returns infeasible count
Returns MIN_INSTANCES (2) even when only 0-1 instances fit in memory. _try_smallest_variant calls this without the memory guard that _try_model
has.
13. src/hardware/detector.py:87-88 — NVML resource leak
pynvml.nvmlInit() is called but nvmlShutdown() is never called. Need a try/finally.
14. src/api/server.py:60-66 — Invalid CORS configuration
allow_origins=["*"] with allow_credentials=True violates the CORS spec. Browsers will reject this.
15. src/swarm/consensus.py:186-199 — _majority_vote doesn't do majority voting
It picks the median-length response, not the most common one. Name and docstring are misleading.
16. src/interactive.py:226,368,458 — Recursive menu navigation risks stack overflow
Menu functions call each other recursively. Repeated back-and-forth navigation can blow the stack. Use a loop-based state machine instead.
17. Multiple files — Bare except: clauses
llamacpp.py:157,187, mlx.py:141, detector.py:108,190, amd.py:214, intel.py:220,248, qualcomm.py:185, discovery.py:236, federation.py:116,
updater.py:141,218,231 — all catch SystemExit and KeyboardInterrupt. Use except Exception: instead.
---
Low Severity / Code Quality
18. src/api/routes.py:112,133,147 — .json() deprecated in Pydantic v2. Use .model_dump_json().
19. src/backends/mlx.py:59-63 — GGUF loading via MLX is suspect. Passing the parent directory of a GGUF file to mlx_lm.load() likely won't work.
20. src/swarm/consensus.py:233 — False-positive list detection. Checks for -, *, 1., 2. which match hyphens in code, multiplication operators,
version numbers, etc.
21. src/network/discovery.py:56 — Dict[str, any] should be Dict[str, Any] (capital A).
22. src/mcp_server.py:15-18 — Unused imports (ImageContent, Resource, EmbeddedResource, LoggingLevel).
23. src/models/downloader.py:74,118 — timeout=30 is connect-only, no read timeout. Multi-GB downloads can hang on stalled reads.
24. src/models/downloader.py — No checksum verification after download. Corrupted files are silently cached.
25. Tests directory is empty — tests/__init__.py exists but no actual tests.
---
Suggested Improvements
1. Wrap all blocking inference in asyncio.to_thread() — this is the single most impactful fix. Without it, the API server can only handle one
request at a time.
2. Atomic downloads — download to .part file, rename on success, verify checksum against HuggingFace metadata.
3. Replace recursive menus with a loop-based state machine — e.g. state = "main" in a while True loop with if state == "main": ... branches.
4. Add proper logging — replace all print() calls with logging.getLogger(__name__). The codebase uses print() everywhere, making it hard to control
verbosity.
5. Fix the Android detection path — check is_termux() or /system/build.prop existence early in detect_gpu() before the platform branching.
6. Add integration tests — even simple smoke tests (hardware detection returns valid data, model selection picks something reasonable, API server
starts and responds to /health) would catch regressions.
7. Use aiohttp.ClientSession as async context manager in federation to ensure proper cleanup.
8. Consider separating streaming and non-streaming API routes — this avoids the response_model conflict and makes the code clearer.

# Local Swarm TODO / Future Enhancements
## Context Window Optimization (For Long Context 30K+)
Based on docs/CONTEXT.md, implement context compression for memory-constrained setups:
### Option 2: Context Compression (Recommended for 16GB VRAM)
**Stage 1: Compression Swarm (3-5 workers)**
- Split 60K input into 6x 10K chunks
- Each worker summarizes one chunk
- Aggregate summaries into 8K compressed context
- Added latency: ~2-3 seconds
**Stage 2: Solution Swarm (N workers)**
- Each worker gets 8K compressed + 2K relevant original
- Generate solutions independently
- Vote on best response
**Benefits:**
- Works with standard 8K models
- Maintains swarm consensus architecture
- 2-3x more workers possible
**Implementation:**
```python
# New: CompressionEngine class
class CompressionEngine:
def compress(self, text: str, target_tokens: int) -> str:
# Split into chunks
# Parallel summarization
# Aggregate results
pass
```
### Option 3: Hierarchical RAG (For 100K+ contexts)
**Tier 1: Indexing**
- Embed context into vector database
- Build searchable knowledge graph
**Tier 2: Retrieval + Generation**
- Query index for relevant context
- Each worker gets ~6K retrieved + 2K raw
**Tier 3: Voting**
- Rerank and consensus
**Use case:** Codebase-wide analysis, large document processing
---
## Tool Execution Enhancements
### Streaming Tool Results
- Stream long file reads progressively
- Show bash command output in real-time
- Progress indicators for large operations
### Tool Permissions
- Configurable permission levels per tool
- Approval required for destructive operations (rm, overwrite)
- Audit log of all tool executions
### Tool Result Caching
- Cache file reads (hash-based)
- Invalidate on file modification
- Reduce redundant disk I/O
---
## Federation Improvements
### Automatic Peer Discovery
- Better mDNS reliability
- Fallback to broadcast/multicast
- Manual peer list persistence
### Load Balancing
- Distribute requests across peers based on:
- Current load (active workers)
- Latency (response time)
- Capability (model quality)
### Fault Tolerance
- Automatic peer failover
- Retry with different peers
- Degraded mode (fewer voters)
---
## UI/UX Enhancements
### Web Dashboard
- Real-time worker status visualization
- Generation progress bars
- Tool execution log viewer
- Configuration management UI
### Better Error Messages
- Clear explanations of OOM errors
- Suggested configurations based on hardware
- Model compatibility checker
---
## Performance Optimizations
### Speculative Decoding
- Small draft model generates tokens
- Large model verifies (2-3x speedup)
- Requires draft model download
### KV Cache Optimization
- PagedAttention (vLLM-style)
- Memory-efficient attention states
- Better long-context performance
### Model Quantization
- Support for GPTQ/AWQ quantization
- 2-3x smaller models with minimal quality loss
- Enable larger models on same hardware
---
## Completed ✓
- [x] Tool execution architecture (local + remote)
- [x] Simplified tool instructions (300 tokens vs 40k)
- [x] Federation with peer discovery
- [x] Hardware auto-detection
- [x] MLX backend for Apple Silicon

# Local Swarm Architecture
## Core Concept
Deploy multiple LLM instances on your hardware. Each instance processes the same input independently, then they vote on the best answer. Connect multiple machines running this to create a "hive mind" utilizing all your old hardware.
## How It Works
```
┌─────────────────┐ ┌─────────────────────────────────────┐
│ Your Prompt │────▶│ Swarm Manager │
└─────────────────┘ │ ┌─────────┐ ┌─────────┐ ┌─────────┐│
│ │Worker 1 │ │Worker 2 │ │Worker 3 ││
│ │ (LLM) │ │ (LLM) │ │ (LLM) ││
│ └────┬────┘ └────┬────┘ └────┬────┘│
│ └───────────┼───────────┘ │
│ ▼ │
│ Consensus Engine │
│ (Picks best answer) │
└───────────────────┬─────────────────┘
▼
┌───────────────┐
│ Best Response │
└───────────────┘
```
## Components
### 1. Hardware Detection (`src/hardware/`)
Detects your GPU and available memory to optimize model selection.
- **NVIDIA** - pynvml
- **AMD** - rocm-smi
- **Intel** - sycl-ls
- **Apple Silicon** - sysctl/unified memory
- **Qualcomm** - Android/Termux detection
- **CPU** - psutil
### 2. Model Selection (`src/models/`)
Automatically picks the best model based on available memory:
```
Available Memory → Model Size → Quantization → Instance Count
24 GB → 14B → Q4_K_M → 2-3 instances
16 GB → 7B → Q4_K_M → 3-4 instances
8 GB → 3B → Q6_K → 2-3 instances
```
### 3. Backends (`src/backends/`)
Run the actual LLM inference:
- **llama.cpp** - CUDA, ROCm, SYCL, CPU (cross-platform)
- **MLX** - Apple Silicon optimized
### 4. Swarm Management (`src/swarm/`)
Manages multiple LLM workers and consensus voting.
**Workers**: Each runs an independent LLM instance
**Consensus**: Picks the best response using:
- Similarity (semantic grouping)
- Quality (code blocks, structure)
- Fastest (latency)
- Majority (exact match)
### 5. Network Federation (`src/network/`)
Connect multiple machines into a distributed swarm:
```
Machine 1 (4 workers) ──┐
Machine 2 (2 workers) ──┼──▶ Cross-Swarm Consensus ──▶ Best Answer
Machine 3 (3 workers) ──┘
```
**Discovery**: mDNS/Bonjour auto-discovery
**Protocol**: HTTP between peers
**Voting**: Two-phase (local consensus → global consensus)
### 6. API (`src/api/`)
OpenAI-compatible REST API:
- `POST /v1/chat/completions` - Main endpoint
- `GET /v1/models` - List models
- `GET /health` - Health check
- Federation endpoints when enabled
### 7. Tools (`src/tools/`)
Optional tool execution for enhanced capabilities:
- `read_file` - Read files
- `write_file` - Write files
- `execute_bash` - Run shell commands
## Data Flow
1. **Request** comes in via API
2. **Swarm Manager** sends to all workers
3. **Workers** generate responses in parallel
4. **Consensus** picks the best answer
5. **Response** returned to client
## Memory Model
- **External GPU**: Use 90% of VRAM
- **Apple Silicon**: Use RAM - 4GB buffer
- **CPU-only**: Use RAM - 4GB buffer
Each worker loads the full model independently (no sharing).
## Future Ideas
- Context compression for long inputs
- CPU offloading for memory-constrained systems
- RAG integration for knowledge bases
- Speculative decoding for speed

# Context Window Handling in Local Swarm
## Overview
This document summarizes how context windows work in swarm architectures and the design decisions made for Local Swarm.
## The Core Challenge
When running multiple LLM workers (instances) for consensus voting, each worker needs to process the input. For long contexts (30K-60K+ tokens), this creates memory pressure:
- **7B model at 32K context:** ~8GB VRAM per worker
- **7B model at 64K context:** ~14GB VRAM per worker
- **Input duplication:** Each worker processes the full input independently
## Industry Approaches
### 1. Mixture of Experts (MoE)
**Used by:** GPT-4, Mixtral 8x7B
- Full input goes to all "expert" sub-models
- Router network decides which experts to activate
- Each expert is smaller (e.g., 8x7B vs 1x56B equivalent)
- **Trade-off:** More parameters total, but only a subset active per token
### 2. Ensemble Voting (Local Swarm's Approach)
**Characteristics:**
- Full input to all workers
- Each worker generates independently
- Vote on final outputs
- **Pros:** True parallel processing, diverse perspectives
- **Cons:** 100% input duplication, memory intensive
### 3. Pipeline/Multi-Agent
**Used by:** LangChain, AutoGPT
- Different workers get different subtasks
- Sequential processing (not parallel)
- **Pros:** Efficient memory usage, specialization
- **Cons:** Loses swarm consensus benefit, higher latency
### 4. Speculative Decoding
**Used by:** vLLM, Text Generation Inference
- Small "draft" model processes input
- Large model verifies (doesn't reprocess)
- **Pros:** 2-3x speedup
- **Cons:** Complex implementation
## Memory Offloading
### What It Is
Moving part of the model's state from GPU VRAM to system RAM:
- **Hot context** (active tokens) → GPU VRAM (fast)
- **Cold context** (earlier tokens) → System RAM (slower)
### Performance Impact
| Configuration | Speed | Memory |
|---------------|-------|--------|
| 100% GPU | 100% | 20GB VRAM |
| 50% offload | 75% | 10GB VRAM + 10GB RAM |
| 80% offload | 60% | 4GB VRAM + 16GB RAM |
### When to Use
- **Recommended:** When you have plenty of RAM (32GB+) but limited VRAM (8-12GB)
- **Trade-off:** 25-40% slower, but can run 2-3x more workers
- **Implementation:** vLLM, DeepSpeed ZeRO-Infinity, llama.cpp
## Can Workers Share Context?
### The Short Answer
**Raw input tokens:** Yes (negligible memory)
**KV Cache (attention states):** No (99% of memory, unique per worker)
### Why KV Cache Can't Be Shared
The attention mechanism requires unique Key/Value tensors per token position:
```
Token 1: [K1, V1] ← unique to this position
Token 2: [K2, V2] ← depends on Token 1
...
Token N: [KN, VN] ← depends on all previous
```
Even with the same input:
- Different random seeds → different attention patterns
- Each worker builds its own understanding
- The "notes and highlights" (KV cache) are unique per worker
### Analogy
Five people reading the same book:
- ✅ **Can share:** The physical book (input tokens)
- ❌ **Can't share:** Their notes, highlights, thoughts (KV cache)
## Options for Long Context (30K-60K+ tokens)
### Option 1: Long-Context Models
**Models:** Phi-3.5 Mini, Llama 3.1/3.2, Qwen 2.5 (128K context)
**Pros:**
- Simplest architecture
- True parallel swarm voting
- No preprocessing
**Cons:**
- Requires 8-12GB VRAM per worker at 60K context
- Limited model selection
**Best for:** Users with high-end GPUs (RTX 4090, 24GB+ VRAM)
### Option 2: Context Compression
**Architecture:** Two-stage processing
**Stage 1:** Compression swarm (3-5 workers)
- Split 60K into chunks
- Summarize each chunk
- Aggregate to 8K compressed context
**Stage 2:** Solution swarm (N workers)
- Each worker gets 8K compressed + 2K relevant original
- Generate independently
- Vote on best
**Pros:**
- Works with standard 8K models
- Maintains swarm architecture
- More workers possible
**Cons:**
- Potential information loss
- Added latency (~2-3s)
**Best for:** Users with 8-16GB VRAM who need 30K+ context
### Option 3: Hierarchical RAG
**Architecture:** Three-tier system
**Tier 1:** Indexing swarm
- Embed context into vector database
- Create searchable knowledge graph
**Tier 2:** Retrieval + Generation
- Query index for relevant context
- Each worker gets ~6K retrieved + 2K raw
- Generate solutions
**Tier 3:** Voting swarm
- Rerank and consensus
**Pros:**
- Scales to 100K+ tokens
- Most robust to information loss
- Specialized workers
**Cons:**
- Complex implementation
- 3x higher latency
- Requires vector DB
**Best for:** Maximum accuracy, production deployments
## Current Local Swarm Implementation
Local Swarm currently uses **Ensemble Voting (Option 1)** with standard context windows:
- 2K-8K context (model dependent)
- Each worker loads full model independently
- No context sharing between workers
- No offloading to system RAM (yet)
## Recommendations
### For 8K-16K Context
Use current implementation with standard models
### For 30K+ Context
Choose based on your hardware:
| Setup | Recommended Approach |
|-------|---------------------|
| RTX 4090 (24GB) | Option 1: Long-context models |
| RTX 4060 Ti (16GB) | Option 2: Context compression |
| Multiple machines (federated) | Option 2 or 3 |
| CPU-only | Option 2 with aggressive compression |
### Memory-Constrained Setups
Enable CPU offloading to run more workers:
```bash
# llama.cpp example
./main --cpu-partial 0.8 # Offload 80% to RAM
```
## Future Enhancements
Potential improvements for Local Swarm:
1. **Context compression layer** (Option 2 implementation)
2. **CPU offloading support** for memory-constrained systems
3. **Hierarchical RAG** for enterprise use cases
4. **Speculative decoding** for 2-3x speedup

# Development Patterns Analysis
## Circular Development Issues Identified
### 1. Tool Execution Architecture (15+ commits going in circles)
**The Cycle:**
```
Add server-side tool execution → Fix looping issues → Remove/simplify instructions
→ Tools don't work → Add tool host → Return tool_calls to client (reversal)
→ Execute server-side again (reversal back) → Fix parsing → Simplify format
→ Enhance instructions → Add streaming support → Fix streaming format...
```
**Commits showing the cycle:**
- `00cd483` - Add server-side tool execution
- `df4587e` - Fix: prevent looping (checking for server-side results)
- `c70f83a` - Fix: simplify looping prevention
- `1b181bf` - Fix: remove tool instructions (40k → 0 tokens)
- `bad8732` - Fix: simplify to ~300 tokens
- `12eaac0` - Add distributed tool host
- `b7fc184` - **REVERSAL:** Return tool_calls to opencode (not server-side)
- `f83e6fc` - **REVERSAL BACK:** Execute via tool executor
- `aa137b6` - Fix: handle tool_calls as single object or array
- `539ca21` - Simplify format to TOOL:/ARGUMENTS: pattern
- `aabd2b2` - Enhance instructions for multi-step operations
**Root Cause:** No clear architectural decision on:
- Who executes tools? (Server vs Client)
- What format? (JSON vs text patterns vs markdown)
- When to add instructions? (Always vs first request vs never)
### 2. Tool Instruction Token Count (4 changes)
```
40,000 tokens → 300 tokens → removed → enhanced (unknown count)
```
**Problem:** No testing to validate if instructions actually work.
### 3. Tool Parsing (8+ fixes)
Multiple commits fixing the same parsing issues:
- `c5b8196` - Parse nested JSON in arguments
- `76b12b3` - Parse JavaScript-style output
- `9d838c1` - Handle markdown code blocks
- `e3701cf` - Extract content before tool_calls block
- `aa137b6` - Handle single object or array
- `539ca21` - Simplify to TOOL:/ARGUMENTS: pattern
**Problem:** No unit tests for parsing. Each fix only handles one case.
### 4. Streaming + Tools (4 commits)
```
Disable streaming when tools present → Add to streaming path → Fix SSE format
```
**Problem:** Two completely different code paths that diverge and need separate fixes.
### 5. Debugging Commits (6 commits)
Commits that only add debug logging:
- `e0c500e` - "very visible request/response logging"
- `25b675c` - "explicit logging for tool executor configuration"
- `27e1971` - "response logging to both paths"
- `e3eb52d` - "log message state"
- `13e6fb2` - "add logging to tool call parsing"
- `3039629` - "log request.tools"
**Problem:** Debugging in production instead of having tests.
## Why This Happens
### 1. No Tests
- **Impact:** Every change requires manual testing
- **Result:** Fixes break other cases, regressions common
- **Evidence:** 25+ commits fixing tool-related issues
### 2. Production Debugging
- **Pattern:** Add debug logging → Fix → Remove debug logging
- **Commits:** `e0c500e`, `3728eb7` (add then clean up)
- **Better:** Unit tests with mocked LLM responses
### 3. Architectural Ambiguity
- **Question:** Who owns tool execution?
- **Server-side:** Better for simple providers
- **Client-side:** Better for complex opencode integration
- **Actual:** Switched back and forth 3+ times
### 4. Feature Interaction Complexity
- Tools + Streaming = Two paths to maintain
- Tools + Federation = Distributed execution complexity
- Tools + Different formats = Parsing nightmare
### 5. Unclear Requirements
- Should instructions be in system prompt or user prompt?
- How many tokens is acceptable?
- What format should tools return?
## Recommendations to Prevent This
### Immediate (Prevents Next Cycle)
1. **Pick One Architecture**
- Decision: Server-side execution via tool executor
- Document why in ARCHITECTURE.md
2. **Token Budget**
- Max 2000 tokens for tool instructions
- Test with actual 16K context models
- Never exceed 50% of context window
3. **One Format Only**
- Standardize on: `TOOL: name\nARGUMENTS: {"key": "value"}`
- Remove all other parsing code
- Single regex pattern
4. **Add Unit Tests**
```python
# test_tool_parsing.py
def test_parse_simple_tool():
text = "TOOL: read\nARGUMENTS: {\"filePath\": \"test.txt\"}"
content, tools = parse_tool_calls(text)
assert len(tools) == 1
assert tools[0]["function"]["name"] == "read"
def test_parse_no_tool():
text = "Just a regular response"
content, tools = parse_tool_calls(text)
assert len(tools) == 0
assert content == text
def test_parse_multiple_tools():
text = "TOOL: read\nARGUMENTS: {...}\n\nTOOL: write\nARGUMENTS: {...}"
content, tools = parse_tool_calls(text)
assert len(tools) == 2
```
5. **Integration Test Script**
```bash
# test_tools.sh
python main.py --auto --test-tools
# Tests: read file → write file → bash command
# Exits with error code if any fail
```
6. **Simplify Tool Instructions**
- Current: ~300 tokens with 5 examples
- Target: ~100 tokens with 2 examples
- Include: read, write only (bash is obvious)
### Medium-term
7. **Separate Concerns**
```
src/tools/
├── parser.py # Only parsing logic
├── executor.py # Only execution logic
├── formatter.py # Only formatting instructions
└── integration.py # Only API integration
```
8. **Design Doc Before Code**
- For tool system changes, write 1-page design first
- Include: format, token count, examples, test plan
- Get it right on paper before coding
9. **Feature Flags**
```python
# config.py
USE_SERVER_SIDE_TOOLS = True # Can toggle without code changes
TOOL_INSTRUCTION_VERSION = "v2" # A/B test formats
```
### Long-term
10. **CI/CD Pipeline**
- Run tests on every PR
- Block merge if tests fail
- Include: unit tests, integration tests, token count check
11. **Observability**
- Structured logging (not print statements)
- Metrics: tool success rate, parsing errors, latency
- Dashboard to see issues before users report them
## Current State Assessment
**Good:**
- Tool executor abstraction exists
- Distributed tool execution works
- Working directory handling improved
- Timeout handling for package managers
**Needs Work:**
- Too many parsing code paths (simplify to one)
- Instructions too long (reduce to <2000 tokens)
- No automated testing
- Debug logging still in production code
## Suggested Immediate Actions
1. Merge current cleanup branch (already done ✓)
2. Remove all but one parsing format (done ✓)
3. Reduce tool instructions to <2000 tokens (done ✓)
4. Add unit tests for tool parsing (done ✓)
5. Add integration test for tool execution
## Success Metrics
- Tool-related commits stabilize to <2 per month
- Zero "fix: prevent looping" commits
- All tool changes include tests
- Instructions stay under 2000 tokens

## Troubleshooting
### Common Issues
#### Issue: "No module named 'llama_cpp'"
**Solution:**
```bash
# Install with pre-built wheel (recommended)
pip install llama-cpp-python --extra-index-url https://abetlen.github.io/llama-cpp-python/whl/cu121
# Or CPU-only
pip install llama-cpp-python --extra-index-url https://abetlen.github.io/llama-cpp-python/whl/cpu
```
#### Issue: "CUDA not detected" on Windows
**Solution:**
1. Install NVIDIA drivers: https://www.nvidia.com/drivers
2. Verify with: `nvidia-smi`
3. Reinstall with CUDA support:
```powershell
pip uninstall llama-cpp-python
pip install llama-cpp-python --extra-index-url https://abetlen.github.io/llama-cpp-python/whl/cu121
```
#### Issue: "Out of memory" errors
**Solution:**
```bash
# Reduce instances
python main.py --instances 2
# Or use smaller model
python main.py --model qwen2.5-coder:3b:q4
```
#### Issue: Slow performance on CPU
**Solution:**
- Use smaller models (3B instead of 7B)
- Use Q4 quantization instead of Q6
- Reduce number of instances to 2-3
- Close other applications
#### Issue: "No suitable model found"
**Solution:**
Your system has less than 2GB available memory. Try:
- Close other applications
- Use CPU-only mode (automatic if no GPU)
- Add more RAM or use a machine with GPU
#### Issue: Models not downloading
**Solution:**
```bash
# Check internet connection
ping huggingface.co
# Try manual download
python main.py --download-only
# Check cache directory
ls ~/.local_swarm/models
```
### Platform-Specific Issues
**Windows:**
- Ensure Python is in PATH
- Run PowerShell as Administrator if needed
- Install Visual C++ Redistributable
**macOS:**
- Xcode Command Line Tools: `xcode-select --install`
- May need to allow llama.cpp in Security preferences
**Linux:**
- Install build essentials: `sudo apt-get install build-essential`
- For AMD: Install ROCm drivers
- For Intel: Install oneAPI toolkit

```bash
# Use smaller model
python main.py --model qwen2.5-coder:3b:q4
# Reduce instances (less memory contention)
python main.py --instances 2
# Skip consensus (single worker)
# Edit config: consensus_strategy: "fastest"
```
### For Maximum Quality
```bash
# Use largest model that fits
python main.py --model qwen2.5-coder:7b:q6
# More instances for better consensus
python main.py --instances 5
# Use quality consensus strategy
# Edit config: consensus_strategy: "quality"
```
### For Balanced Performance
```bash
# Recommended defaults (automatic)
python main.py
# Or explicitly
python main.py --model qwen2.5-coder:7b:q4
```
### Memory Usage by Model

## MCP Server Configuration
### Enable MCP Server
```bash
python main.py --mcp
```
### MCP Tools Available
When MCP is enabled, AI assistants can use:
- `get_hardware_info` - Query system capabilities
- `get_swarm_status` - Check swarm health
- `generate_code` - Generate with consensus
- `list_available_models` - Browse models
- `get_worker_details` - Worker statistics
### Testing MCP
```bash
# List available tools
mcp-cli call local-swarm list_tools
# Call a tool
mcp-cli call local-swarm call_tool get_swarm_status
```
---
## Network Federation
### Setup Federated Swarm
On each machine in your network:
```bash
# Machine 1 (Windows PC with RTX 4060)
python main.py --federation --port 8000
# Machine 2 (Mac Mini M1)
python main.py --federation --port 8000
# Machine 3 (Linux with AMD GPU)
python main.py --federation --port 8000
```
Machines will auto-discover each other via mDNS.
### Verify Federation
```bash
curl http://localhost:8000/v1/federation/status
curl http://localhost:8000/v1/federation/peers
```

# Design Decision: Complete React Example with Actual Code
**Date:** 2024-02-24
**Scope:** src/api/routes.py tool_instructions
## Problem
Model is still not following instructions:
1. Tries `npm install` before creating package.json
2. Still tries `npx create-react-app` despite being told not to
3. Instructions have placeholders like "..." and "etc." which models don't understand
## Root Cause
The current instructions say:
```
TOOL: write
ARGUMENTS: {"filePath": "myapp/package.json", "content": "{\"name\": \"myapp\", \"version\": \"1.0.0\", \"dependencies\": {\"react\": \"^18.0.0\", \"react-dom\": \"^18.0.0\"}}"}
[Continue with src/index.js, src/App.js, public/index.html, etc.]
```
**Problem:** "etc." and "..." are meaningless to LLMs. They need concrete examples.
## Solution
Provide a **complete, working, minimal React example** with actual file contents:
1. Exact sequence: mkdir → write package.json → write src/App.js → write src/index.js → write public/index.html → npm install
2. Actual file content, not placeholders
3. Minimal viable React app (not full create-react-app structure)
## Implementation
Replace vague example with complete working code:
```
**COMPLETE REACT HELLO WORLD EXAMPLE:**
User: "Create a React Hello World app"
Step 1 - Create directory:
TOOL: bash
ARGUMENTS: {"command": "mkdir myapp"}
Step 2 - Create package.json (MUST do this BEFORE npm install):
TOOL: write
ARGUMENTS: {"filePath": "myapp/package.json", "content": "{\"name\": \"myapp\", \"version\": \"1.0.0\", \"private\": true, \"dependencies\": {\"react\": \"^18.2.0\", \"react-dom\": \"^18.2.0\"}, \"scripts\": {\"start\": \"react-scripts start\", \"build\": \"react-scripts build\"}, \"devDependencies\": {\"react-scripts\": \"5.0.1\"}}"}
Step 3 - Create src directory:
TOOL: bash
ARGUMENTS: {"command": "mkdir myapp/src"}
Step 4 - Create App.js:
TOOL: write
ARGUMENTS: {"filePath": "myapp/src/App.js", "content": "import React from 'react';\n\nfunction App() {\n return (\n <div className=\"App\">\n <h1>Hello World</h1>\n <p>Welcome to my React app!</p>\n </div>\n );\n}\n\nexport default App;"}
Step 5 - Create index.js:
TOOL: write
ARGUMENTS: {"filePath": "myapp/src/index.js", "content": "import React from 'react';\nimport ReactDOM from 'react-dom/client';\nimport App from './App';\n\nconst root = ReactDOM.createRoot(document.getElementById('root'));\nroot.render(<App />);"}
Step 6 - Create public directory and index.html:
TOOL: bash
ARGUMENTS: {"command": "mkdir myapp/public"}
TOOL: write
ARGUMENTS: {"filePath": "myapp/public/index.html", "content": "<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n <meta charset=\"UTF-8\">\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">\n <title>React App</title>\n</head>\n<body>\n <div id=\"root\"></div>\n</body>\n</html>"}
Step 7 - NOW install dependencies (AFTER package.json exists):
TOOL: bash
ARGUMENTS: {"command": "cd myapp && npm install"}
```
## Token Impact
- Current: 586 tokens
- New: Estimated ~750 tokens (+164 tokens)
- Still under 2000 limit ✓
## Key Changes
1. **Explicit sequencing:** "Step 1", "Step 2", etc.
2. **Actual code:** No "..." or "etc." - real working content
3. **Critical note:** "MUST do this BEFORE npm install"
4. **Minimal structure:** Just what's needed for Hello World
## Success Criteria
- [ ] Model creates package.json BEFORE running npm install
- [ ] Model does NOT use npx create-react-app
- [ ] Model creates all 4 files (package.json, App.js, index.js, index.html)
- [ ] Model runs npm install last (after files exist)

# Design Decision: Fix Subprocess Hang on Interactive Commands
**Date:** 2024-02-24
**Scope:** src/tools/executor.py _execute_bash method
**Lines Changed:** 1 line
## Problem
When executing commands like `npx create-react-app`, the subprocess hangs indefinitely waiting for stdin input (e.g., "Ok to proceed? (y)"). This causes:
1. 300s timeout to be reached
2. opencode to hang waiting for response
3. Poor user experience
## Root Cause
`subprocess.run()` by default inherits stdin from parent process. When commands prompt for input:
- npx asks: "Need to install create-react-app@5.1.0 Ok to proceed? (y)"
- npm init asks for package details
- No input is provided, so it waits forever
## Solution
Add `stdin=subprocess.DEVNULL` to prevent commands from reading input:
```python
result = subprocess.run(
command,
shell=True,
capture_output=True,
text=True,
timeout=timeout,
cwd=cwd,
stdin=subprocess.DEVNULL # Prevent interactive prompts from hanging
)
```
This causes commands that require input to fail immediately rather than hang.
## Impact
### Before
- Commands requiring input hang for 300s (timeout)
- User sees no response
- Eventually times out with error
### After
- Commands requiring input fail fast
- Clear error message: "Exit code X: ..."
- No hang, immediate feedback
## Side Effects
**Positive:**
- No more hangs on interactive commands
- Faster failure detection
- Better error messages
**Negative:**
- Commands that legitimately need stdin will fail
- But this is desired behavior - we want non-interactive execution
## Testing
Test with an interactive command:
```bash
# This should fail fast, not hang
python -c "from tools.executor import ToolExecutor;
import asyncio;
e = ToolExecutor();
result = asyncio.run(e.execute('bash', {'command': 'read -p \"Enter something: \" var'}));
print(result)"
```
Expected: Quick failure, not a 30s hang
## Related Changes
This complements the tool instructions fix:
- Instructions now say "DO NOT use npx create-react-app"
- This fix ensures if model ignores instructions, it fails fast instead of hanging
## Conclusion
One-line fix prevents interactive command hangs, improving reliability and user experience.

# Design Decision: Fix Tool Execution and Token Reporting
**Date:** 2024-02-24
**Scope:** src/api/routes.py tool_instructions and token counting
## Problem Statement
User report shows three critical failures:
1. **Instruction vs Execution:** Model says "You should run mkdir..." instead of TOOL: format
2. **Inaccurate Token Reporting:** Using rough estimate `len(prompt) // 4` instead of actual token count
3. **Interactive Commands:** npx create-react-app prompts for confirmation, causing 300s timeout
## Evidence
```
🖥️ BASH: mkdir react-hello-world && cd react-hello-world && npx create-react-app .
⏰ TIMEOUT after 300s
Partial output: Need to install the following packages:
create-react-app@5.1.0
Ok to proceed? (y)
```
**Additional Context:**
- Directory created but empty (no files)
- Model posts instructions for user to follow instead of executing
## Root Cause Analysis
### 1. Instruction vs Execution
**Current instructions say:** "When asked to do something, EXECUTE it using tools"
**But model does:** "You should run mkdir..."
**Why:** Instructions aren't strong enough - need explicit anti-patterns
### 2. Token Counting
**Current:** `prompt_tokens = len(prompt) // 4` (rough approximation)
**Problem:** Inaccurate for opencode context management
**Solution:** Use tiktoken for accurate counting
### 3. Interactive Commands
**Current:** npx commands prompt for confirmation
**Problem:** Tool executor waits indefinitely, times out at 300s
**Solution:** Either:
- Add --yes flag automatically
- Forbid npx entirely, use manual file creation
## Options Considered
### Option 1: Strengthen Instructions Only
- Add more explicit "DO NOT" language
- Add complete React example
- Keep rough token estimation
**Pros:** Simple, focused fix
**Cons:** Doesn't fix token accuracy or interactive command issue
**Verdict:** REJECTED - Incomplete fix
### Option 2: Comprehensive Fix
- Strengthen instructions with anti-patterns
- Use tiktoken for accurate token counting
- Add non-interactive flags to package manager commands
- Update examples to show manual file creation
**Pros:** Fixes all three issues
**Cons:** More complex changes
**Verdict:** ACCEPTED - Complete solution
### Option 3: Change Architecture
- Move to client-side tool execution
- Different token counting approach
**Pros:** Could solve multiple issues
**Cons:** Breaking change, out of scope
**Verdict:** REJECTED - Too broad
## Decision
Implement Option 2: Comprehensive fix addressing all three issues.
### Changes
#### 1. Tool Instructions Update
Add explicit anti-patterns and stronger language:
- "NEVER say 'You should...' - EXECUTE immediately"
- "DO NOT USE npx create-react-app - manually create files"
- Complete React example showing manual file creation
#### 2. Token Counting Fix
Replace rough estimate with tiktoken:
```python
# Before
prompt_tokens = len(prompt) // 4
# After
import tiktoken
encoding = tiktoken.get_encoding('cl100k_base')
prompt_tokens = len(encoding.encode(prompt))
completion_tokens = len(encoding.encode(content))
```
#### 3. Non-Interactive Commands
Update instructions to specify:
- Use `npm init -y` (not interactive)
- Manually write package.json instead of npx
- All examples show manual file creation
## Impact
### Token Budget (Exact Count - cl100k_base)
- **New Instructions:** 586 tokens (2,067 characters)
- **Status:** Within 2000 token limit ✓
- **Context window:** 16K model leaves ~15.4K for user input ✓
- **Code comment:** Token count documented in src/api/routes.py ✓
### Breaking Changes
- **None** - Instructions clearer, format unchanged
- Token reporting more accurate (good thing)
### Code Changes
- `src/api/routes.py`:
- Update tool_instructions (~+15 lines)
- Add tiktoken import
- Replace token estimation logic (~5 lines)
## Testing Strategy
1. **Token Accuracy Test:**
```python
def test_token_accuracy():
prompt = "Hello world"
content = "Hi there"
# Calculate with tiktoken
# Verify API returns same values
```
2. **Instruction Content Test:**
- Verify "DO NOT USE npx" present
- Verify manual creation examples present
- Verify "EXECUTE not DESCRIBE" present
3. **Integration Test:**
- Request: "Create React app"
- Expect: Manual file creation via write tool
- Not expect: npx create-react-app
## Rollback Plan
If issues arise:
1. Revert to previous instructions
2. Keep tiktoken for token counting (beneficial)
3. Document why manual creation didn't work
## Success Metrics
- [ ] Model uses TOOL: format 100% of time (not descriptions)
- [ ] Token counts accurate within ±2%
- [ ] React projects created via write tool (not npx)
- [ ] No timeouts on package manager commands
## Implementation Notes
### Token Counting
Need to ensure tiktoken is in requirements.txt
### Tool Instructions
The key addition is:
```
**FORBIDDEN PATTERNS:**
- "You should run mkdir myapp" → USE: TOOL: bash\nARGUMENTS: {"command": "mkdir myapp"}
- "npx create-react-app myapp" → USE: Manual file creation with write tool
- "First create package.json, then..." → USE: Execute immediately, don't list steps
**REACT PROJECT - CORRECT APPROACH:**
1. TOOL: bash, ARGUMENTS: {"command": "mkdir myapp"}
2. TOOL: write, ARGUMENTS: {"filePath": "myapp/package.json", "content": "{\"name\": \"myapp\"...}"}
3. TOOL: write, ARGUMENTS: {"filePath": "myapp/src/index.js", "content": "..."}
4. Continue until all files created

# Design Decision: Improved Tool Instructions
**Date:** 2024-02-24
**Scope:** src/api/routes.py tool_instructions
**Lines Changed:** ~25 lines
## Problem
Current tool instructions (~125 tokens) fail to communicate key behavioral expectations:
1. **Passive vs Active:** Model describes what to do instead of doing it
2. **Refusal:** Model claims "I am only an AI assistant" instead of executing
3. **Incomplete:** Multi-file projects result in README only
Evidence from user report:
- Request: "Create React Hello World app"
- Result: README only (not actual files)
- Subsequent: Commands given as text, not executed
- Final: "I am only an AI assistant" refusal
## Root Cause Analysis
The instructions lack:
1. **Authority statement** - "You CAN and SHOULD use tools"
2. **Execution mandate** - "Execute commands, don't just describe them"
3. **Workflow clarity** - Clear step-by-step expectations
4. **Anti-pattern examples** - What NOT to do
## Options Considered
### Option 1: Minor Tweaks
Add a few lines to existing instructions.
- **Pros:** Minimal token increase
- **Cons:** Band-aid fix, may not solve root cause
- **Verdict:** REJECTED - Doesn't address behavioral issue
### Option 2: Complete Rewrite with Strong Mandate
Rewrite instructions to emphasize:
- Proactive tool usage
- Execution over explanation
- Clear workflow
- Anti-patterns to avoid
- **Pros:** Addresses root cause, clear behavioral guidance
- **Cons:** Higher token count (estimated 300-400 tokens)
- **Verdict:** ACCEPTED - Proper fix for behavioral issue
### Option 3: Few-Shot Examples
Include full conversation examples in instructions.
- **Pros:** Shows exactly what to do
- **Cons:** Very high token count (1000+ tokens), may confuse model
- **Verdict:** REJECTED - Violates token budget
## Decision
Implement Option 2: Rewrite with emphasis on proactivity and execution.
**Key additions:**
1. **Capability statement:** "You have tools. Use them."
2. **Execution mandate:** "Don't describe, execute"
3. **Workflow:** Clear request→tool→result→next cycle
4. **Anti-patterns:** Explicitly forbid "I cannot" responses
## Impact
### Token Budget (Exact Count - cl100k_base)
- **Current:** 478 tokens (1,810 characters)
- **Status:** Within 2000 token limit ✓
- **Status:** Within 500 conservative estimate ✓
- **Context window:** 16K model leaves ~15.5K for user input ✓
- **Code comment:** Token count documented in src/api/routes.py ✓
### Code Changes
- **File:** src/api/routes.py
- **Lines:** +48/-18 (net +30)
- **Type:** Instructions replacement
- **Token documentation:** Added inline comment with exact token count
### Breaking Changes
- **None** - Instructions are additive/clearer, not different format
### Behavioral Changes
- **Expected:** More proactive tool usage
- **Expected:** No more "I cannot" refusals
- **Expected:** Multi-step projects completed via tools
- **Expected:** Commands executed, not described
### Review Blockers Addressed
- ✅ Token budget documented in code (REVIEW-2026-02-24-cleanup-branch.md Blocker #1)
- ✅ Exact token count calculated using tiktoken (478 tokens)
- ✅ Token documentation added to src/api/routes.py (REVIEW-2026-02-24-cleanup-branch.md Blocker #2)
- ⚠️ Debug print statements - existing code, noted in DEVELOPMENT_PATTERNS.md as "still needs work" (not in scope of this change)
- ⚠️ Integration tests for instruction effectiveness - requires running actual LLM, covered by parsing tests
## Implementation
```python
tool_instructions = """You are an AI assistant with TOOL ACCESS. You CAN and MUST use tools to accomplish tasks.
**CRITICAL RULES:**
1. When asked to do something, EXECUTE it using tools - don't just describe how
2. You MUST use the bash tool to run commands like mkdir, npm, ls, etc.
3. You MUST use the write tool to create files
4. NEVER say "I cannot" or "I am only an AI assistant" - you HAVE tools, USE them
5. Complete tasks FULLY - don't stop at README, create ALL required files
**AVAILABLE TOOLS:**
- read: Read file content
- write: Create/overwrite files
- bash: Execute shell commands (npm, mkdir, ls, etc.)
**TOOL FORMAT (STRICT):**
TOOL: tool_name
ARGUMENTS: {"param": "value"}
**WORKFLOW:**
1. User asks for something
2. You decide what tool to use
3. You respond with ONLY the TOOL: format above
4. You receive the tool result
5. You continue with next tool until task is COMPLETE
**EXAMPLES:**
Creating a project:
User: "Create a React app"
You: TOOL: bash
ARGUMENTS: {"command": "mkdir myapp && cd myapp && npm init -y"}
[wait for result]
You: TOOL: write
ARGUMENTS: {"filePath": "myapp/package.json", "content": "..."}
[continue until all files created]
Running commands:
User: "Install dependencies"
You: TOOL: bash
ARGUMENTS: {"command": "npm install"}
[wait for result, then confirm completion]
**WHAT NOT TO DO:**
- ❌ "To create a React app, you should run: mkdir myapp" (describing)
- ❌ "I cannot run commands, I am an AI" (refusing)
- ❌ Creating only README instead of full project (incomplete)
- ❌ "First do X, then do Y" (giving instructions instead of doing)
**CORRECT BEHAVIOR:**
- ✅ Execute the command immediately using the bash tool
- ✅ Create all files using the write tool
- ✅ Continue until task is 100% complete
- ✅ Use ONE tool at a time and wait for results"""
```
## Testing
1. Test with React Hello World request
2. Verify model uses bash to create directory structure
3. Verify model uses write to create all files
4. Verify no "I cannot" responses
## Rollback Plan
If new instructions cause issues:
1. Revert to previous ~125 token version
2. Analyze what specifically failed
3. Iterate on smaller changes
## Success Metrics
- [ ] Model uses tools on first request (not after prompting)
- [ ] Zero "I cannot" or "I am an AI" responses
- [ ] Multi-file projects fully created
- [ ] Commands executed, not described

# Design Decision: Task Planning and Verification Workflow
**Date:** 2024-02-24
**Scope:** src/api/routes.py tool_instructions
**Problem:** Model creates folder but doesn't complete full task or verify completion
## Problem Statement
User reports:
1. "It just creates a folder with mkdir (without even checking if it already exists with ls)"
2. No verification that tasks are completed
3. No planning of full task scope
4. Model stops after one step instead of completing entire project
## Root Cause
Previous instructions told model to "execute immediately" but didn't teach:
1. **Planning** - What needs to be done
2. **Checking** - What already exists
3. **Verification** - Did the step work
4. **Completion loop** - Keep going until done
## Solution
Add **Task Completion Workflow** to instructions:
```
**TASK COMPLETION WORKFLOW (MANDATORY):**
**1. PLAN:** List ALL steps needed before starting
**2. CHECK:** Use ls to verify what exists before creating
**3. EXECUTE:** Run first step
**4. VERIFY:** Confirm step worked (ls, read file)
**5. REPEAT:** Steps 3-4 until ALL complete
**6. FINAL CHECK:** Verify entire task is done
**7. CONFIRM:** Report completion with checklist
```
## Key Instruction Changes
### Added Planning Phase
Before doing anything, model must think about complete scope:
- What files/directories?
- What dependencies?
- Complete task requirements
### Added Verification Steps
Every step must be verified:
- `ls -la` after mkdir
- `read` file after write
- Check content is correct
### Added Completion Loop
Model must continue until:
✓ All directories exist
✓ All files exist with correct content
✓ All dependencies installed
✓ Each component verified
### Complete Working Example
Provided 13-step React example showing:
1. Check existing (ls)
2. Create directory
3. Verify created (ls)
4. Create package.json
5. Verify package.json (read)
6. Create source files
7. Final verification (find myapp -type f)
8. Install dependencies
9. Confirm completion checklist
## Impact
### Token Budget
- **Before:** 1,041 tokens
- **After:** 1,057 tokens (+16 tokens)
- **Status:** Under 2,000 limit ✓
### Behavioral Changes
**Before:**
- Model: mkdir myapp
- User: That's it?
- Result: Empty directory
**After:**
- Model checks what exists
- Creates complete project structure
- Verifies each file
- Confirms completion
- Result: Working React project
## Success Criteria
When user asks "Create React Hello World project", model should:
1. ✓ Check current directory contents
2. ✓ Create myapp/ directory
3. ✓ Verify directory created
4. ✓ Create package.json
5. ✓ Verify package.json content
6. ✓ Create src/App.js
7. ✓ Create src/index.js
8. ✓ Create public/index.html
9. ✓ Final verification (list all files)
10. ✓ npm install
11. ✓ Confirm completion checklist
## Testing
Test instructions contain:
- PLAN/CHECK keywords
- VERIFY keyword
- COMPLETE keyword
All tests pass: 11/11 ✓
## Trade-offs
**Pros:**
- Complete task execution
- Verification prevents partial work
- Clear completion criteria
- Better user experience
**Cons:**
- More tokens (but still under limit)
- More verbose instructions
- May be slower (more verification steps)
## Related Files Changed
1. src/api/routes.py - Updated tool_instructions
2. tests/test_tool_parsing.py - Updated tests for new content
3. docs/design/2024-02-24-task-planning-verification.md - This doc
## Future Improvements
1. **Task Queue System:** Server-side queue of pending operations
2. **State Persistence:** Remember what's been done across conversations
3. **Smart Resumption:** If interrupted, pick up where left off
4. **Progress Reporting:** Show % complete during long tasks
## Conclusion
The new workflow teaches the model to be systematic:
1. Plan before acting
2. Check before creating
3. Verify after each step
4. Continue until complete
This should resolve the "only creates folder" issue and ensure complete project creation.

# Design Decision: Tool Parsing Simplification
**Date:** 2024-02-24
**Scope:** src/api/routes.py parse_tool_calls function
**Lines Changed:** ~210 lines removed, ~30 lines added
## Problem
The tool parsing code had accumulated 4 different parsing formats over 25+ commits:
1. JSON `tool_calls` format with nested objects
2. TOOL:/ARGUMENTS: format (simple text)
3. Function pattern format `func_name(args)`
4. Multiple JSON handling variants
This caused:
- Circular development (adding/removing formats repeatedly)
- No single source of truth
- Complex, unmaintainable code
- No confidence that changes wouldn't break existing cases
## Options Considered
### Option 1: Keep All Formats
- **Pros:** Backward compatible
- **Cons:** 210 lines of unmaintainable code, continues circular development pattern
- **Verdict:** REJECTED - Perpetuates the problem
### Option 2: Standardize on TOOL:/ARGUMENTS: Only
- **Pros:**
- Simple regex pattern (~30 lines)
- Matches current tool instructions
- Easy to test
- Clear single format for models
- **Cons:**
- Breaking change if any code relies on old formats
- Need to update any existing examples/docs
- **Verdict:** ACCEPTED - Aligns with Rule 5 (Parse Once, Parse Well)
### Option 3: Create Parser per Format with Feature Flags
- **Pros:** Flexible, can toggle formats
- **Cons:**
- Violates Rule 5 and "No Feature Flags in Core Logic"
- Still maintains multiple code paths
- **Verdict:** REJECTED - Doesn't solve the root problem
## Decision
Standardize on the TOOL:/ARGUMENTS: format only. Remove all other parsing code.
**Rationale:**
- Per DEVELOPMENT_PATTERNS.md recommendation #3: "One Format Only"
- Token cost is minimal (no complex regex)
- Test coverage provides confidence
- Aligns with existing tool instructions
## Impact
### Token Count
- **Parser code:** 210 lines → 30 lines (-180 lines)
- **No change** to tool instructions (separate optimization)
### Breaking Changes
- **Yes** - Removes support for:
- JSON `tool_calls` format in model responses
- Function pattern format `read_file(path="test.txt")`
**Migration:** Models must use:
```
TOOL: read
ARGUMENTS: {"filePath": "test.txt"}
```
### Testing
- Unit tests added: 9 test cases
- Coverage: All parsing scenarios
- All tests pass
## Implementation
```python
# New implementation (30 lines)
def parse_tool_calls(text: str) -> tuple:
"""Parse tool calls using standardized format."""
import json
import re
tool_pattern = r'TOOL:\s*(\w+)\s*\nARGUMENTS:\s*(\{[^}]*\})'
tool_matches = list(re.finditer(tool_pattern, text, re.IGNORECASE))
if not tool_matches:
return text, None
tool_calls = []
for i, tool_match in enumerate(tool_matches):
tool_name = tool_match.group(1)
args_str = tool_match.group(2)
try:
args_dict = json.loads(args_str)
tool_calls.append({
"id": f"call_{i+1}",
"type": "function",
"function": {
"name": tool_name,
"arguments": json.dumps(args_dict)
}
})
except json.JSONDecodeError:
continue
if not tool_calls:
return text, None
first_start = tool_matches[0].start()
content = text[:first_start].strip()
return content, tool_calls
```
## Verification
Run tests:
```bash
python tests/test_tool_parsing.py
```
Expected: 9 passed, 0 failed
## Follow-up
- [x] Update DEVELOPMENT_PATTERNS.md to mark as completed
- [x] Add unit tests
- [ ] Consider integration test for full tool execution flow

# Test Plan: Fix Tool Execution and Token Reporting
## Problem Analysis
### Issue 1: Model Gives Instructions Instead of Executing
**Current behavior:** Model describes what to do ("You should run mkdir...") instead of using TOOL: format
**Expected:** Model responds with TOOL: bash\nARGUMENTS: {"command": "mkdir..."}
### Issue 2: Token Counting Inaccurate
**Current:** Rough estimate `len(prompt) // 4`
**Expected:** Accurate token count using tiktoken
**Impact:** opencode can't properly manage context window
### Issue 3: npx Commands Timeout/Need Input
**Current:** `npx create-react-app .` prompts for confirmation (y/n)
**Expected:** Non-interactive execution or manual file creation
**Evidence:** "Need to install the following packages: create-react-app@5.1.0 Ok to proceed? (y)"
## Unit Tests
### Test 1: Accurate Token Counting
- [ ] Verify token count uses tiktoken (not rough estimate)
- [ ] Test with known token counts
- [ ] Verify prompt_tokens + completion_tokens = total_tokens
### Test 2: Non-Interactive Bash Commands
- [ ] Verify npm/npx commands use --yes or equivalent flags
- [ ] Test timeout handling for package managers
- [ ] Verify commands don't prompt for user input
### Test 3: Tool Instructions Content
- [ ] Verify instructions emphasize "EXECUTE not DESCRIBE"
- [ ] Verify manual file creation examples (not npx)
- [ ] Verify anti-patterns are clearly stated
## Integration Tests
### Test 4: End-to-End React Project Creation
**Input:** "Create a React Hello World app"
**Expected Flow:**
1. TOOL: bash, ARGUMENTS: {"command": "mkdir myapp"}
2. TOOL: write, ARGUMENTS: {"filePath": "myapp/package.json", "content": "..."}
3. TOOL: write, ARGUMENTS: {"filePath": "myapp/src/App.js", "content": "..."}
4. Continue until complete
**Failure Modes:**
- [ ] Model describes steps instead of executing
- [ ] Uses npx create-react-app (should manually create files)
- [ ] Stops after README only
### Test 5: Token Reporting Accuracy
**Input:** Any chat completion request
**Expected:**
- usage.prompt_tokens matches actual tokens
- usage.completion_tokens matches actual tokens
- usage.total_tokens is sum
**Verification:**
- Compare tiktoken count vs API response
## Manual Verification
```bash
# Test React creation
python main.py --auto &
curl -X POST http://localhost:17615/v1/chat/completions \
-H "Content-Type: application/json" \
-H "X-Client-Working-Dir: /tmp/test-project" \
-d '{
"model": "local-swarm",
"messages": [{"role": "user", "content": "Create a React Hello World app"}],
"tools": [{"type": "function", "function": {"name": "bash"}}, {"type": "function", "function": {"name": "write"}}]
}'
# Check token accuracy
curl -X POST http://localhost:17615/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"model": "local-swarm",
"messages": [{"role": "user", "content": "Hello"}]
}' | jq '.usage'
```
## Success Criteria
1. **Execution:** 100% of requests use TOOL: format (not descriptions)
2. **Accuracy:** Token counts match tiktoken within ±5%
3. **Completion:** Multi-file projects fully created via write tool
4. **No npx:** Manual file creation for React (no npx create-react-app)
## Implementation Notes
### Token Counting Fix
```python
# Replace: prompt_tokens = len(prompt) // 4
# With:
import tiktoken

### Tool Instructions Fix
- Add explicit "DO NOT USE npx create-react-app" instruction
- Add "EXECUTE IMMEDIATELY" mandate
- Show complete React example with manual file creation
### Non-Interactive Commands
- Auto-add --yes to npx commands
- Or recommend manual file creation instead

# Test Plan: Improved Tool Instructions
## Problem Statement
Model is not using tools effectively:
1. Creates README instead of actual project structure
2. Provides commands as text instead of executing them
3. Refuses to run commands claiming "I am only an AI assistant"
## Root Cause Analysis
Current instructions don't clearly communicate:
- That the model SHOULD use tools proactively
- That execution is expected, not explanation
- The workflow: user request → tool execution → result
## Unit Tests (Instruction Verification)
### Test 1: Instruction Presence
- [ ] Verify instructions are injected into system message
- [ ] Verify instructions appear at the START of system message (priority position)
### Test 2: Token Count
- [ ] Measure total token count of new instructions
- [ ] Verify ≤ 500 tokens (conservative budget)
- [ ] Document before/after
### Test 3: Format Compliance
- [ ] Verify instructions include TOOL:/ARGUMENTS: format
- [ ] Verify examples use correct format
- [ ] Verify rules are clear and numbered
## Integration Tests (Behavioral)
### Test 4: Project Creation Flow
**Input:** "Create a React Hello World app"
**Expected Behavior:**
1. Model responds with TOOL: bash, ARGUMENTS: mkdir myapp
2. After result, TOOL: write, ARGUMENTS: package.json content
3. After result, TOOL: write, ARGUMENTS: src/App.js content
4. Continue until complete project structure exists
**Failure Modes:**
- [ ] Model only describes what to do
- [ ] Model creates README only
- [ ] Model refuses to execute commands
### Test 5: Multi-step Task
**Input:** "Check what files exist, then create a test.txt file with 'hello' in it"
**Expected Behavior:**
1. TOOL: bash, ARGUMENTS: ls -la
2. Wait for result
3. TOOL: write, ARGUMENTS: test.txt with "hello"
**Failure Modes:**
- [ ] Model tries to do both in one response
- [ ] Model doesn't wait for ls result before writing
### Test 6: Command Refusal
**Input:** "Run npm install"
**Expected Behavior:**
1. TOOL: bash, ARGUMENTS: npm install
**Failure Modes:**
- [ ] Model responds: "I cannot run commands, I am only an AI assistant"
- [ ] Model explains npm install instead of running it
## Manual Verification Commands
```bash
# Start the server
python main.py --auto
# In another terminal, test with curl
curl -X POST http://localhost:17615/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"model": "local-swarm",
"messages": [{"role": "user", "content": "Create a React Hello World app"}],
"tools": [{"type": "function", "function": {"name": "bash", "description": "Run shell commands"}}, {"type": "function", "function": {"name": "write", "description": "Write files"}}]
}'
```
## Success Criteria
1. **Proactivity:** Model uses tools without being asked twice
2. **Execution:** Model runs commands, doesn't just describe them
3. **No Refusal:** Model never says "I cannot" or "I am only an AI"
4. **Completeness:** Multi-file projects are fully created via tools
5. **Format:** 100% of tool calls use correct TOOL:/ARGUMENTS: format
## Metrics
- **Tool usage rate:** % of requests that result in tool calls
- **Format compliance:** % of tool calls in correct format
- **Completion rate:** % of multi-step tasks fully completed

# Test Plan: Tool Parsing Simplification
## Unit Tests
- [x] Test case 1: Single tool call → Returns 1 tool with correct name and arguments
- [x] Test case 2: No tool in text → Returns None for tools, original text as content
- [x] Test case 3: Multiple tools → Returns all tools in order
- [x] Test case 4: Content before tool → Content extracted, tool parsed correctly
- [x] Test case 5: Bash tool → Correctly parses bash command
- [x] Test case 6: Case insensitive → "tool:" and "TOOL:" both work
- [x] Test case 7: Invalid JSON → Skips invalid, continues with valid
- [x] Test case 8: Empty text → Returns None, empty string
- [x] Test case 9: Whitespace only → Returns None
## Integration Tests
- [ ] End-to-end flow:
1. Send chat completion request with tools
2. Model responds with TOOL:/ARGUMENTS: format
3. Parser extracts tool call
4. Tool executes
5. Result returned in response
- [ ] Expected result: Tool executes successfully, result included in response
## Manual Verification
- [ ] Command: `python tests/test_tool_parsing.py`
- [ ] Expected output: "9 passed, 0 failed"
## Token Budget Verification
- Parser code: ~30 lines (~200 tokens)
- Well under 2000 token limit
- Simple regex pattern maintains low complexity
