git-toolbox

A plugin that provides various Git-related functionalities to interact with Git repositories.

Skills

/check-github-ci — Check GitHub Actions CI status and provide root cause analysis with fix suggestions for any failures. Retrieves PR check results, identifies failed jobs, fetches error logs, and suggests specific fixes.

/create-draft-pr [--ja] — Automated draft PR creation based on Git change analysis. Performs pre-flight checks, analyzes branch changes, generates PR descriptions (using templates if available), and creates draft PRs. Supports English (default) and Japanese output.

/semantic-commit [--dry-run] [--lang <en|ja>] — Split large changes into meaningful minimal units and commit them sequentially with semantic commit messages. Detects project conventions (CommitLint config, commit history patterns) and language preferences automatically.

/pr-auto-update [--pr <num>] [--dry-run] [--lang <en|ja>] — Auto-update PR descriptions by analyzing Git changes. Preserves existing content and HTML comments, only fills in empty sections. Uses GitHub API directly to avoid comment escaping issues.

qa-toolbox

A plugin that provides QA workflow tools for test case generation and quality assurance.

Skills

/create-dev-check-list-android [description] — Generate a minimal developer self-check checklist for Android (Kotlin/Gradle) projects from git diff. Categorizes changed files (UI, ViewModel, Repository, DI, Build, etc.) and generates relevant verification checks. Copies output to clipboard.

/copy-simple-qa-cases [--lang en|ja] [PR number] — Generate QA test cases from branch diff and PR body for manual testing handoff. Produces structured test cases with preconditions, steps, and expected results. Copies output to clipboard.

ccusage-analyzer

Analyze Claude Code usage and costs using the ccusage CLI to provide insights on token consumption and spending patterns.

Skills

/analyze-usage [--monthly] [--session] [--since YYYYMMDD] [--until YYYYMMDD] [--breakdown] — Analyze token usage and costs via ccusage CLI. Provides daily/monthly/session reports with cost summaries, cache hit rates, trend analysis, spike detection, and optimization recommendations.

Or install all plugins via the marketplace:

claude plugin add --from https://github.com/b4tchkn/claude-code-plugins

Prerequisites

• GitHub CLI (gh) — Required by git-toolbox and qa-toolbox for PR operations and CI status checks
• ccusage — Required by ccusage-analyzer (npm install -g ccusage or use via npx)

Release Workflow

This repository uses an automated two-stage release pipeline via GitHub Actions:

1. Create Release PR — Triggered manually via workflow_dispatch. Select a plugin and version bump type (patch/minor/major). The workflow bumps the version in plugin.json, updates the marketplace version, and opens a PR to main.
2. Publish Release — Triggered automatically when a release PR (branch prefix release/) is merged to main. Creates a Git tag ({plugin}/v{version}) and a GitHub Release with auto-generated notes.

Contributing

Contributions are welcome! To add a new plugin or skill:

1. Create a new directory under plugins/ following the existing structure
2. Add a .claude-plugin/plugin.json with plugin metadata
3. Add skills under skills/{skill-name}/SKILL.md
4. Register the plugin in .claude-plugin/marketplace.json
5. Open a PR
