  19. Status: Ready to merge

Experimental Infrastructure (Keep but Inactive)

  1. vLLM Setup Script ✅
  2. File: scripts/setup_vllm_thor.sh
  3. Status: Documented, not run by default

  4. Purpose: Future local LLM experiments

  5. Test Scripts ✅

  6. File: test_tool_call_format.sh
  7. Status: Useful for debugging tool calling
  8. Purpose: Validate LLM responses

Technical Debt / TODOs

  • [ ] Remove debug logging from DIMOS agent.py (or make it conditional) ✅ DONE (changed to DEBUG level)
  • [ ] Test Wait skill more thoroughly (observed issues in multi-step commands)
  • [ ] Test Qwen2.5-Coder-7B tool calling consistency
  • [ ] Document vLLM custom chat template requirements
  • [ ] Add vLLM health check to start.sh
  • [ ] Consider model registry system (swap models easily)
  • [ ] Profile memory usage on Thor (can we run 13B models?)

Merge Steps

1. Clean Up Debug Code

cd /workspaces/shadowhound/src/dimos-unitree
# Edit agent.py: Change emoji logs from INFO to DEBUG level
# Or remove them if not needed

# Commit to DIMOS
git add dimos/agents/agent.py
git commit -m "cleanup: convert debug logs to DEBUG level"
git push origin fix/webrtc-instant-commands-and-progress

2. Update Submodule Reference

cd /workspaces/shadowhound
git submodule update --remote src/dimos-unitree
git add src/dimos-unitree
git commit -m "chore: update DIMOS submodule with agent improvements"

3. Final Validation

# Test cloud config one more time
./start.sh
# Send a few commands, verify tool calling works
# Ctrl+C to stop

4. Merge to Dev

git checkout dev
git pull origin dev
git merge feature/local-llm-support --no-ff -m "feat: local LLM support + agent improvements

- Add tool_choice='auto' and temperature=0.0 to DIMOS OpenAIAgent
- Improves tool calling consistency for all LLM backends
- Add vLLM infrastructure for future local LLM experiments
- Add local embeddings support (sentence-transformers)
- Optimize system prompt and token limits
- Add dual configuration system (cloud + local)
- Document local LLM integration journey

Cloud LLM (GPT-4o): Production ready, 100% consistent tool calling
Local LLM (vLLM): Experimental, needs more tuning

Tested with:
- GPT-4o: ✅ Perfect (2.89-7.27s response time)
- Mistral-7B: ⚠️ Works but inconsistent (~60% success)
- Qwen2.5-Coder-7B: ⚠️ Works but needs tuning

See docs/local_llm_integration_summary.md for details."

git push origin dev

5. Clean Up Branch (Optional)

# Delete local branch
git branch -d feature/local-llm-support

# Delete remote branch (if desired)
git push origin --delete feature/local-llm-support

Post-Merge Validation

On Dev Branch

  • [ ] Cloud config works (GPT-4o)
  • [ ] Tool calling consistent
  • [ ] No regressions in existing functionality
  • [ ] Documentation accessible
  • [ ] Other team members can test

Optional: Test Local Config

  • [ ] Uncomment local config in .env
  • [ ] Start vLLM on Thor
  • [ ] Verify it still works (even if inconsistent)
  • [ ] Switch back to cloud config

Rollback Plan (If Needed)

If something breaks after merge:

git checkout dev
git revert HEAD  # Reverts the merge commit
git push origin dev

Or more aggressive:

git checkout dev
git reset --hard HEAD~1  # Removes merge commit
git push origin dev --force  # DANGEROUS - only if no one else pulled
