# Plan: Update README for Knowledge Hub Enhancements

## Goal
Bring the public README files in sync with the current local Knowledge Hub implementation before committing and pushing the work to GitHub.

## Scope
- Update README command descriptions for `ag refresh` and `ag ask`
- Document `.antigravity/structure.md` as a generated artifact
- Describe the Router-Worker ask flow and scoped code-exploration tools
- Keep edits limited to documentation plus the already-reviewed Knowledge Hub code/tests

## Verification
- Re-read updated README sections for consistency with current code
- Run the focused Hub test suite
- Commit only intended source, tests, and README files
