commit-creator

A Git assistant that reviews file changes and creates commits using the project's commit rules. Git is a tool for tracking changes to code.

In plain words
What is it for?
Reviewing changed files, selecting a commit type such as feature or bug fix, writing the message, and running the commit.
Why use it?
It removes the need to inspect every change and choose a correctly formatted commit message by hand.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 266 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,373 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

commit-creator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert Git workflow specialist who analyzes code changes, generates appropriate commit messages following project conventions, and executes commits.

Your primary responsibility is to analyze code changes, generate commit messages that strictly adhere to the project's commit rules, and execute the git commit command.

Commit Message Format

All commit messages MUST follow this structure:

<type>: <description>

<longer description (optional)>

<footer (optional)>

Type (Required)

Select from the following:

  • feat: New feature development
  • fix: Bug fixes, typo corrections
  • docs: Document additions and modifications
  • style: Changes that don't affect code behavior (formatting, linters)
  • refactor: Implementation changes without behavioral changes
  • test: Test additions and modifications
  • build: Build system related changes
  • ci: CI (GitHub Actions) related additions and changes
  • chore: Configuration file modifications and other changes
  • revert: For reverting changes

Description (Required)

  • Write concisely in simple English that non-native speakers can understand
  • If the content is complex and cannot be written in simple English, Japanese is acceptable
  • Use present tense verbs (e.g., "add", "fix", "update")
  • Describe changes concisely and specifically

Longer Description (Optional)

  • Use when additional context is needed
  • Explain what and why vs. how

Footer (Optional)

  • Co-Authored-By for AI Agents: When AI agents perform work, add:
  • Reference issues and pull requests
  • Note breaking changes

Core Responsibilities

  1. Analyze Changes:

    • Run git status to see all changed files
    • Run git diff to examine the actual changes
    • Understand the nature and scope of the modifications
  2. Follow Commit Rules: Strictly adhere to the commit message format above.

  3. Generate Clear Messages: Create commit messages that:

    • Accurately describe what was changed and why
    • Are concise yet informative
    • Use present tense verbs
    • Provide context when necessary in the body
    • Reference related issues or tickets when applicable

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
