Antigravity with an AGENTS.md file requesting suggestions

 I added a section to the AGENTS.md like this:

## 7. Version Control & Commit Messages

- **Code Review**:
  - Always do a code review before committing. In addition to finding and
    suggesting fixes to issues, try to create 1-3 suggestions for improvement to
    the code based on the current changes.

I have gone with the changes the last couple runs as they have almost all been great so far.

● Bash(git status -s) (ctrl+o to expand)

▸ Thought for 3s, 27 tokens

  Everything is completed, verified, tested, and cleanly committed! Let's present ...

  I have added macOS to the GitHub Actions CI test matrix, updated the project documentation, and committed the

  changes.

  ### Summary of Work

  • Updated CI Workflow: Expanded the matrix strategy in test.yml to include  macos-latest  alongside

  ubuntu-latest  (with  fail-fast: false ), ensuring matrix jobs run across Python 3.13 and 3.14 on both Linux and

  macOS.

  • Updated Documentation: Added a note under Section 5 in AGENTS.md documenting that CI tests run

  automatically across Linux and macOS.

  • Verified & Committed: All pre-commit checks passed ( uv run pre-commit run --all-files ), and created

  conventional commit  4e50f4c  on branch  main :

    ci(workflow): add macOS to GitHub Actions test matrix

    Expand test job strategy matrix in .github/workflows/test.yml to execute across both ubuntu-latest and macos-

  latest with fail-fast disabled, and update AGENTS.md cross-platform testing guidelines.

  ### Code Review Suggestions for Improvement

  In accordance with our mandatory code review policy in AGENTS.md, here are 3 suggestions for future

  improvement based on this CI addition:

  1. Windows CI Support: To guarantee full cross-platform compatibility across all desktop environments, we could

  also evaluate adding  windows-latest  to the OS matrix in test.yml, specifically to verify line endings,

  file paths, and file object streaming behavior on Windows.

  2. Benchmark Execution Scoping: Currently,  --benchmark-only  runs in CI when  matrix.python-version == '3.14' 

  across all operating systems. Shared macOS runners in GitHub Actions can experience high timing variance; if

  this causes flaky benchmark thresholds in CI, we could restrict benchmark execution strictly to Ubuntu ( if: ...

  && matrix.os == 'ubuntu-latest' ).

  3. OS-Specific Cache Monitoring: We should monitor  uv  cache restore and save durations across OS runners in

  GitHub Actions to ensure that  astral-sh/setup-uv  cache eviction and key scoping remain optimal on macOS

  virtual environments.
