commitor

---

name: commitor description: Generate commit messages combining GitMoji, Conventional Commits, and Keep a Changelog. Use when the user wants to prepare a commit message, write a commit title, generate a conventional commit, add an emoji prefix, or describe staged changes. By default, only outputs the formatted message — executes git commit only when the user explicitly asks to commit. Also handles merge commit summarization: use "merge to " to analyze the full branch diff.

Commitor

Generate commit messages combining GitMoji + Conventional Commits + Keep a Changelog.

By default, output the formatted title and description in chat for the user to review — do not run git commit. Only execute the commit if the user explicitly asks (e.g., "use commitor and commit", "commit with commitor").

Workflow

1. Run git diff --cached (or git diff if nothing is staged) to analyze changes
2. Pick the single most appropriate commit type from the table below
3. Determine the scope if relevant (e.g., auth, panel, exports)
4. Write a short title in imperative mood and a bullet-point description
5. Default: output the result in chat for review
6. If the user asked to commit: run git commit with the generated message

Merge Mode

Trigger: user says "merge to <branch>" or "merge commit to <branch>".

The current branch is the source; <branch> is the merge target (e.g., main).

Workflow:

# All commits on current branch since divergence
git log <branch>..HEAD --format="---COMMIT---%n%H%n%s%n%b" --reverse

# Cumulative diff stat for context
git diff <branch>...HEAD --stat

Then:

• Read all individual commits to understand the full scope
• Pick the highest-significance type (feat > fix > patch > rest)
• Synthesize a single commit message — group changes by theme, not one bullet per commit

Output Format

Standard commit:

<emoji> <type>(<scope>): <description> (<TASK-XXX>)

- First key change
- Second key change
- ...

Breaking change (append !, add footer):

<emoji> <type>(<scope>)!: <description>

- Key change

BREAKING CHANGE: <what breaks and how to migrate>

Scope and task number are optional. Only include them when relevant.

Rules

• English by default; match the language of the existing changelog or commit history if evident
• Title in lowercase, imperative mood ("add" not "added")
• Title < 72 characters (including emoji and type prefix)
• One type/emoji per commit
• Description as concise bullet points (no trailing periods)
• Use Unicode emojis (not :shortcodes:)
• Scope is optional — use to specify the area of the commit (e.g., auth, panel, api)
• Task number is optional — use project prefix format (e.g., NTT-123, BH-42)
• Breaking changes: append ! after type/scope and add a BREAKING CHANGE: footer describing what breaks and how to migrate

Changelog Mapping

Reference for mapping commit types to Keep a Changelog categories:

Changelog Category	Commit Types
Added	feat
Changed	patch, style, perf, data
Fixed	fix, security
Removed	remove
Breaking	any type with !
Technical	docs, refactor, test, ai, config, build

wip commits are excluded from changelogs — they don't represent releasable changes.
