Initial commit: coding harness feedback analysis

Harnesses under analysis:
- opencode (Go-based coding agent)
- pi (minimal terminal coding harness by Mario Zechner)
- hermes (Nous Research agent)
- forgecode (AI pair programmer with sub-agents)

Each harness folder contains:
- repo/: Source code from respective repositories
- feedback/localllm/: Community feedback for local/smaller models
- feedback/frontier/: Community feedback for frontier models

Research focus: Tool handling, skills systems, prompt engineering,
context management, and best practices for smaller/local models.

+## Research/Analysis Folder for opencode
+
+This is the research and analysis folder for the **opencode** coding harness.
+
+### Folder Structure
+
+```
+opencode/
+  repo/           - opencode-ai/opencode source code
+  feedback/
+    localllm/     - Community feedback and performance data for local models
+    frontier/     - Community feedback and performance data for frontier models
+```
+
+### What's Inside
+
+- **repo/**: The official opencode repository (Go-based coding agent)
+- **feedback/localllm/**: Feedback, benchmark results, and observations from using opencode with smaller/local LLMs
+- **feedback/frontier/**: Feedback, benchmark results, and observations from using opencode with frontier models
+
+### Feedback Format
+
+Each feedback file should include:
+- Model used (name, size, provider)
+- Benchmark results or task performance
+- Issues encountered
+- What worked well
+- **Source reference**: URL or site where the feedback came from (community posts, Discord, GitHub issues, etc.)
+
+### Research Focus
+
+This folder collects data on:
+- Tool handling and capabilities
+- Skills system effectiveness
+- Prompt engineering strategies
+- Context management
+- Performance on benchmarks (terminal-bench, etc.)
+
+### Goal
+
+Extract best practices specifically for smaller/local models and document what works vs. what doesn't for the opencode harness. General use / use with frontier models information should be put in the feedback/frontier folder.
