git-commit-writer is a skill for Claude Code, Codex from Jignesh-Ponamwar/skills-mcp. It costs 58 tokens per session (975 once invoked), scanned A, original, Apache-2.0.

A tool for turning staged changes or code differences into standard Git commit messages. It follows Conventional Commits, a shared format that labels changes such as features, fixes, tests, and documentation.

In plain words
What is it for?
Use it when committing code changes or when you need a correctly formatted message from a diff or change description.
Why use it?
It removes the guesswork from writing consistent, informative project history.

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

git-commit-writer 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 5d ago.

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.

Git Commit Writer Skill

Overview

Generate precise, conventional commit messages from diffs or change descriptions. Follows the Conventional Commits 1.0.0 specification used by Angular, Vue, and thousands of open-source projects.

Conventional Commits Format

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

Types

Type When to use
feat New feature visible to users
fix Bug fix
docs Documentation only changes
style Formatting, whitespace (no logic change)
refactor Code restructuring (no feature or fix)
perf Performance improvement
test Adding or correcting tests
build Build system, dependency changes
ci CI/CD configuration changes
chore Other changes (e.g. updating .gitignore)
revert Revert a previous commit

Breaking Changes

Add ! after the type/scope, and a BREAKING CHANGE: footer:

feat(api)!: remove deprecated /v1/users endpoint

BREAKING CHANGE: The /v1/users endpoint has been removed. Use /v2/users instead.

Step-by-Step Process

Step 1: Understand the Change

Ask for or read the diff (git diff --staged or git diff HEAD). Understand:

  • What changed (files, functions, logic)
  • Why it changed (bug fix, new requirement, refactor)
  • Whether it's a breaking change

Step 2: Choose the Type

Apply the type that matches the primary intent. If a PR mixes types, flag it - atomic commits are better.

Step 3: Choose the Scope (Optional)

Scope = the subsystem or module affected. Examples: (auth), (api), (ui), (db).

  • Use it when the codebase has clear module boundaries
  • Omit it for small or cross-cutting changes

Step 4: Write the Description

Rules:

  • Imperative mood: "add feature" not "added feature" or "adds feature"
  • Lowercase first letter
  • No period at the end
  • Max 72 characters on the first line
  • Describe WHAT, not HOW

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
