- Add --use-opencode-tools flag to main.py
- Default: local tool server mode (~125 tokens, saves ~27k tokens)
- Optional: opencode tools mode (~27k tokens, full tool definitions)
- Create .opencodeignore to exclude large docs from context
- Update design doc with token bloat analysis
This allows users to choose between:
- Local tool server: Minimal tool instructions, saves 27k tokens
- Opencode tools: Full tool definitions, more robust but expensive
