Commit and Pull Request

Creates commits and PRs that follow Arena's contributor guidelines.

Commit

Run the pre-commit-check skill (or pre-commit run --all-files on the host — pre-commit is not installed in the container) until the working tree is clean. Do not commit through hook failures.
Stage specific files rather than using git add -A — this avoids accidentally committing dotfiles, credentials, or large untracked artifacts.
Sign off the commit (per CONTRIBUTING.md — Arena currently requires DCO sign-off; the policy is on the books but not yet CI-enforced):
```
git commit -s -m "<subject>"
```
Subject line: imperative mood, ~50 characters, no trailing period.
- Good: Fix attribute access on wrapped env
- Bad: Fixed the attribute access on the wrapped env. (past tense, trailing period)
Body (when needed): blank line after the subject, wrap at 72 chars, explain what and why — not how (the diff shows that).
No AI attribution lines. Do not include Co-Authored-By: Claude..., Generated with Claude Code, or similar footers. The DCO sign-off is the only required trailer.
