🎣 Git Hooks

Install/Uninstall

rco hook set    # Install prepare-commit-msg hook
rco hook unset  # Remove hook

Once installed, git commit (without -m) automatically generates commit messages!

# Pre-generation hook
rco config set RCO_PRE_GEN_HOOK="just lint; just test -q"

# Pre-commit hook
rco config set RCO_PRE_COMMIT_HOOK="./scripts/tweak_commit.sh"

# Post-commit hook
rco config set RCO_POST_COMMIT_HOOK="git push"

# Hook behavior
rco config set RCO_HOOK_STRICT=false       # Allow hook failures
rco config set RCO_HOOK_TIMEOUT_MS=60000   # Timeout in ms

Skip Hooks (Per-Run):

rco --no-pre-hooks      # Skip pre-gen + pre-commit hooks
rco --no-post-hooks     # Skip post-commit hooks

🧠 Advanced Features

Enable detailed commit messages with body explaining the "why":

rco config set RCO_ENABLE_COMMIT_BODY=true

Output:

feat(auth): implement OAuth2 PKCE flow

- Add secure token storage with automatic refresh
