conventional-commit

conventional-commit is a skill for Claude Code, Codex from HirogaKatageri/hirokata. It costs 90 tokens per session (2,154 once invoked), scanned A, original, MIT.

A tool for creating commit messages in the Conventional Commits format, a shared way to label code changes such as features, fixes, tests, or documentation.

In plain words
What is it for?
Use it to review changed files, group related work, and generate one or more structured commit messages.
Why use it?
It removes the need to inspect changes and decide how to group and describe them by hand, while keeping commit history consistent.

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

conventional-commit 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 4d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (examples/multi-commit-workflow.sh, scripts/group-changes.py, scripts/validate-commit-msg.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Conventional Commit Generator

Generate properly formatted conventional commits by analyzing changes, grouping related modifications, and creating semantic commit messages following the Conventional Commits specification.

Purpose

Automate the process of reviewing code changes, identifying logical groupings, and generating conventional commit messages. Ensure commits follow the Conventional Commits specification while providing control over commit granularity (separate small commits, combined medium commits, or a single large commit).

Conventional Commit Format

Follow the standard format:

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

<body>

<footer>

Type (required):

  • feat: New feature
  • fix: Bug fix
  • docs: Documentation changes
  • style: Code style changes (formatting, missing semicolons, etc.)
  • refactor: Code refactoring without changing functionality
  • perf: Performance improvements
  • test: Adding or updating tests
  • build: Build system or dependency changes
  • ci: CI/CD configuration changes
  • chore: Maintenance tasks, tooling changes
  • revert: Reverting previous commits

Scope (optional): Component or module affected (e.g., auth, api, ui, parser)

Subject (required): Brief imperative description (≤50 chars)

Body (optional): Detailed explanation of what and why

Footer (optional): Breaking changes, issue references

Workflow

Step 1: Analyze Changes

Run git commands in parallel to gather change information:

# View status (never use -uall flag)
git status

# View unstaged changes
git diff

# View staged changes
git diff --cached

# Recent commit messages for style reference
git log --oneline -10

Review the output to understand:

  • What files have changed
  • What modifications were made
  • Current staging status
  • Existing commit message patterns in the repository

Step 2: Group Related Changes

Analyze the changes and identify logical groupings based on:

Grouping criteria:

  • Purpose: Changes serving the same goal (e.g., all authentication-related)
  • Type: Same conventional commit type (e.g., all bug fixes)
  • Scope: Same component or module (e.g., all API changes)
  • Dependencies: Changes that depend on each other
  • File proximity: Related files in the same directory or feature

Files

What ships with it

6 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.

conventional-commit is a skill published in the GitHub repository HirogaKatageri/hirokata (5 stars, last pushed 18d ago), licensed MIT. It adds 90 tokens to every session and 2,154 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
