Git Commit with Conventional Commits

Create standardized, semantic git commits using the Conventional Commits specification combined with Chris Beams' seven rules. Analyze the actual diff to determine appropriate type, scope, and message.

Pre-Flight: Repository Contribution Guidelines

Before committing, check the repository for contribution guidance:

1. Search for guidelines in: CONTRIBUTING.md, AGENTS.md, README.md, .github/PULL_REQUEST_TEMPLATE.md, .github/ISSUE_TEMPLATE/
2. If found: follow the repo's conventions for commit messages, branch naming, and PR format. Repo rules override the defaults below.
3. Ensure you're on a feature branch — never commit to main/master. If on the default branch, create a branch first: git checkout -b <type>/<short-description>

Conventional Commit Format

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

Commit Types

The Seven Rules

1. Separate subject from body with a blank line

2. Limit the subject line to 50 characters

Aim for 50 characters (soft limit). Maximum 72 characters (hard limit).

3. Capitalize the subject line

feat: Add feature not feat: add feature

4. Do not end the subject line with a period

5. Use the imperative mood in the subject line

"Add feature" not "Added feature" or "Adds feature".

Validation test: "If applied, this commit will [your subject line here]"

6. Wrap the body at 72 characters

7. Use the body to explain what and why vs. how

The diff shows what changed. The body explains why.

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)

# 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).

2b. Scan for Secrets (MANDATORY)

Before proceeding to commit, scan the staged diff for leaked secrets:

git diff --staged

Check for these patterns in the diff output:

• API keys: sk-, ctx7sk-, ghp_, ghu_, ghs_, AKIA, xox[bpas]-
• Tokens/auth: Bearer , token=, authorization:, api[_-]?key
• Passwords: password, passwd, secret, credential
• Connection strings: connectionString, Server=, mongodb://, postgres://, redis://
• Private keys: -----BEGIN, .pem, .pfx, .p12, .key files
• Cloud: AWS_SECRET, AZURE_, GCP_, GOOGLE_APPLICATION_CREDENTIALS

If ANY secrets are detected:

1. STOP — do not commit
2. Tell the user exactly what was found (file, line, pattern matched)
3. Suggest moving the value to an environment variable or .env file
4. Verify .env is in .gitignore
5. Only proceed after the secret is removed from staged changes

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 (present tense, imperative mood, <72 chars)

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
)"

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

Examples

✅ Good Examples

feat: Add caching to database queries

Application was making redundant database calls for user profile
data on every request, causing 200ms latency on profile pages.

Implement Redis-based caching layer with 5-minute TTL for user
profiles. Cache is invalidated on profile updates. Reduces
profile page load time from 250ms to 50ms in production.

Closes #42

fix: Resolve autofix preflight failures

Autofix preflight aborted in --yes/--dry-run because debug
logging returned non-zero when ACFS_DEBUG was off.

Fix debug logging to always succeed and initialize change-recording
state before writes.

docs: Fix typo in installation documentation

chore: Update Node.js to v20 LTS

❌ Bad Examples

• fixed the bug - No type prefix, past tense, too vague
• Updated files - No type prefix, past tense, lists files
• Add feature. - No type prefix, ends with period
• feat add thing - Missing colon after type

Pre-Commit Checklist

• Staged diff scanned for secrets (API keys, tokens, passwords, private keys)
• No secrets present in staged changes
• Starts with valid type prefix (feat:, fix:, etc.)
• Subject ≤50 characters (hard max 72)
• Capitalized first word after prefix
• No trailing period
• Uses imperative mood
• Body explains what and why (if present)

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)
