Gitmoji

Generates commit messages that follow the gitmoji convention: every commit starts with an emoji that identifies the intent of the change at a glance. Given a diff, a list of staged files, or a plain description of a change, this skill picks the single most appropriate gitmoji and writes a concise, well-formed commit message around it.

This skill only generates the message — it never runs git commit or any other git command. The output is a copyable message for the user to use.

When to Use This Skill

• User says "write a gitmoji commit", "gitmoji this change", or "add an emoji to my commit message"
• User asks "which gitmoji should I use for this?"
• User pastes a git diff or describes a change in a project that uses gitmoji-style commit history
• User wants an expressive, scannable commit history using emojis

When not to use: if the project follows plain Conventional Commits (feat:, fix:, ...) without emojis, use the conventional-commit or commit-message-storyteller skill instead. If unsure which convention the project uses, ask the user to provide recent commit history (for example, the output of git log --oneline -10).

Message Format

The gitmoji specification:

<intention> [scope?][:?] <message>

• intention — exactly one gitmoji expressing the goal of the commit
• scope (optional) — the section of the codebase affected, in parentheses
• message — a brief imperative explanation of the change

Examples:

✨ add multi-tenant support to the billing service
🐛 (auth) prevent token refresh loop on expired sessions
♻️ (api): extract pagination logic into shared helper

Emoji Style: Unicode vs Shortcode

Gitmoji supports two equivalent notations:

Match the repository's existing history. If recent commits use :sparkles:-style shortcodes, generate shortcodes; otherwise default to unicode emojis.

How It Works

Step 1: Understand the Change

Work from whatever the user provides:

1. A git diff — read it and identify what changed and why
2. A list of staged/modified files — infer intent from file names and paths
3. A plain description — use it directly

If the intent is genuinely ambiguous (e.g. "updated auth.js" could be a fix, a feature, or a refactor), ask one short clarifying question rather than guessing.

Step 2: Identify the Dominant Intent

Determine the primary purpose of the change. Common intents and their gitmojis:

This is only the most common subset — always consult references/gitmoji-reference.md for the full official list of 75 gitmojis before settling on one; a more specific emoji often exists (e.g. 🩹 for a trivial fix, ✏️ for a typo, 🚚 for a file move).

Step 3: Pick Exactly One Emoji

Rules for ambiguous cases:

• Specific beats generic — a typo fix is ✏️, not 🐛; moving files is 🚚, not ♻️; a trivial non-critical fix is 🩹, not 🐛
• Tests: ✅ for adding/updating passing tests; 🧪 only for intentionally failing tests (e.g. TDD red step)
• Fix vs hotfix: 🚑️ only for urgent production fixes; everyday bug fixes are 🐛
• Security fix: 🔒️ wins over 🐛 when the bug is a security issue
