Git Commit Message Generator

Generate structured git commit messages following industry best practices.

Workflow

Get context (optional):
Analyze as much context as possible:
- Git diff output
- Recent commit history
- Issue tracker references
- Requirements or problems being solved
- Branch context
Choose message type:
feat: New feature
fix: Bug fix
docs: Documentation
style: Code formatting (no logic change)
refactor: Refactoring (no behavior change)
perf: Performance improvement
test: Test additions/changes
build: Build system/dependencies
ci: CI configuration
chore: Maintenance tasks
revert: Revert previous commit
Consider scope (optional):
Noun describing section of codebase
Example: (api), (ui), (auth)
Format: <type>(<scope>)
Write subject line (required):
Concise summary (≤50 characters, or ≤70 for Sentry)
Imperative mood: "Add", "Fix", "Update", "Remove"
Present tense: "Add feature" not "Added feature"
Capitalized first letter
No period at end
Write body (optional but recommended):
WHY: Explain motivation, problem, or user impact
WHAT: Describe what changed (briefly—code already shows HOW)
1–3 sentences max
Separate from subject with blank line
Wrap at 72 characters
Add footer (if applicable):
Issue references: Fixes SENTRY-123, Closes #456
Breaking changes: BREAKING CHANGE: API endpoints now require auth
AI attribution: Co-Authored-By: <AI Name> <email>

Format

<type>(<scope>): <subject>

<body>

<footer>

Header: Required. All lines ≤ 100 chars.

Body: Optional. Use it to explain WHY the change was made—infer from context or requirements when possible. Be brief.

Scope (optional): Noun describing a section.

Commit Types

Type	Purpose
`feat`	New feature
`fix`	Bug fix
`ref`	Refactoring (no behavior change)
`perf`	Performance improvement
`docs`	Documentation only
`test`	Test additions or corrections
`build`	Build system or dependencies
`ci`	CI configuration
`chore`	Maintenance tasks
`style`	Code formatting (no logic change)
`meta`	Repository metadata
`license`	License changes

Subject Line

Imperative mood: "Add", "Fix", "Update"
Present tense: "Add feature" not "Added feature"
Capitalized first letter
Maximum 70 characters (or 50 for standard)
No period at end

Body Guidelines

WHY: Explain motivation, problem, or user impact
WHAT changed: The actual code change (brief)
Avoid: Implementation details (code already shows HOW)
Explain tradeoffs when relevant

AI Attribution

When changes were primarily generated by an AI coding agent, include:

Co-Authored-By: <AI Name> <email>

Important: Do NOT add phrases like "Generated by AI", "Written with Claude", or similar in subject/body. Only use the Co-Authored-By footer line.

Examples

Simple Fix

fix(auth): Handle null response in user endpoint

The API could return null for deleted accounts, causing a crash.
Add null check before accessing user properties.

Fixes SENTRY-5678

Feature

feat(alerts): Add Slack thread replies for alert updates

When an alert is updated or resolved, post a reply to the
original Slack thread. This keeps related notifications grouped together.

Refs GH-1234

Refactor

ref(validation): Extract common validation logic to shared module

Move duplicate validation code from three endpoints into a shared
validator class. No behavior change.

Breaking Change

feat(api)!: Remove deprecated v1 endpoints

Remove all v1 API endpoints that were deprecated in version 23.1.
Clients should migrate to v2 endpoints.

BREAKING CHANGE: v1 endpoints no longer available
Fixes SENTRY-9999
