## Git Commit Style Preferences

**NEVER commit unless explicitly asked by the user.**

When committing: review `git diff`

- Use conventional commit format: `type: subject line`
- Keep subject line concise and descriptive
- **NEVER include marketing language, promotional text, or AI attribution**
- **NEVER add "Generated with Claude Code", "Co-Authored-By: Claude", or similar spam**
- Follow existing project patterns from git log
- Prefer just a subject and no body, unless the change is particularly complex

Example good commit messages from this project:
- `test: allow dead code in test utility methods`
- `fix: improve error handling`
- `feat: add a --fallback option to .static to support SPAs`
- `refactor: remove axum dependency, consolidate unix socket, tcp and tls handling`

## Tone and Communication

Prefer calm, matter-of-fact technical tone like "docs: improve release process with lessons from 0.6.4".

## Code Quality

Always run `./scripts/check.sh` before committing. Use `cargo fmt` to fix formatting issues.

## Release Process

Use `/release [version]` command to execute the automated release workflow. See `.claude/commands/release.md` for details.
