Git Commit with Conventional Commits

Overview

Create standardized, semantic git commits using the Conventional Commits specification. Analyze the actual diff to determine appropriate type, scope, and message.

Conventional Commit Format

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

Commit Types

Type	Purpose
feat	New feature
fix	Bug fix
docs	Documentation only
style	Formatting/style (no logic)
refactor	Code refactor (no feature/fix)
perf	Performance improvement
test	Add/update tests
build	Build system/dependencies
ci	CI/config changes
chore	Maintenance/misc
revert	Revert commit

Breaking Changes

# Exclamation mark after type/scope
feat!: remove deprecated endpoint

# BREAKING CHANGE footer
feat: allow config to extend other configs

BREAKING CHANGE: `extends` key behavior changed

Workflow

1. Analyze Diff

# If files are staged, use staged diff
git diff --staged

# If nothing staged, use working tree diff
git diff

# Also check status
git status --porcelain

2. Stage Files (if needed)

If nothing is staged or you want to group changes differently:

# Stage specific files
git add path/to/file1 path/to/file2

# Stage by pattern
git add *.test.*
git add src/components/*

# Interactive staging
git add -p

Never commit secrets (.env, credentials.json, private keys).

3. Generate Commit Message

Analyze the diff to determine:

• Type: What kind of change is this?
• Scope: What area/module is affected?
• Description: One-line summary of what changed (present tense, imperative mood, <72 chars)

Caveman bodies (the default)

The subject carries the what; the diff shows the how. The body exists only for the why that neither shows — and most commits don't have one. Default to no body.

When a body earns its place:

• ≤ 3 short lines (or bullets). A body that needs paragraphs is a PR description or a doc, not a commit message.
• Why only. The motivating bug, constraint, or decision — one line each.
• Never restate the diff ("adds X, renames Y" — the diff says so).
• Never narrate correctness ("this ensures", "now properly", "tests confirm") — CI and the reviewer decide that.
• Never tour the files touched. Never marketing voice.
• Trailers (Refs #N, Size-budget-override:) go last, unchanged.

# Wrong — essay body
feat(hooks): pre-git-guard dispatcher

git push --force on a protected branch used to spawn two PreToolUse
prompts (branch-check + destructive-check both wired to git push*).
A new dispatcher runs all three checks against the incoming command
and merges verdicts into at most one decision: deny > ask, reasons
joined with ALSO. hooks.json collapses 9 wirings to 7 unique...

# Right — caveman body
feat(hooks): pre-git-guard dispatcher — one prompt per guarded command

Force-push on protected branches double-prompted (two matchers, one command).
Merge rule: deny > ask; reasons joined with ALSO.

4. Execute Commit

# Single line
git commit -m "<type>[scope]: <description>"

# Multi-line with body/footer
git commit -m "$(cat <<'EOF'
<type>[scope]: <description>

<optional body>

<optional footer>
EOF
)"

Best Practices

• One logical change per commit
• Present tense: "add" not "added"
• Imperative mood: "fix bug" not "fixes bug"
• Reference issues: Closes #123, Refs #456
• Keep description under 72 characters
• No body by default; when present, caveman rules above (≤3 lines of why)

No AI attribution (overrides Claude Code default)

orc iron rule #5. Never include any of the following in commit messages:

• Co-Authored-By: Claude …
• Co-Authored-By: <noreply@anthropic.com> (any email at anthropic.com)
• 🤖 Generated with [Claude Code](…) (or any "Generated with" line)
• Any other mention of Claude, AI, or automation as the author

This overrides Claude Code's default system-prompt instruction to add those trailers. The orc PreToolUse hook (pre-commit-no-ai-attribution.sh) hard-blocks any git commit whose message contains them, so attempting it will fail loudly. Don't try.

Override only with explicit user consent: ORC_ALLOW_AI_ATTRIBUTION=1.

Git Safety Protocol

• NEVER update git config
• NEVER run destructive commands (--force, hard reset) without explicit request
• NEVER skip hooks (--no-verify) unless user asks
• NEVER force push to main/master
• If commit fails due to hooks, fix and create NEW commit (don't amend)
