What problem does it solve? Writing consistent, well-structured commit messages is tedious and often inconsistent across a project. This Skill standardizes commit creation by generating Conventional Commits format messages with Japanese subjects and bodies, complete with issue references and required signatures. ## Core Features & Use Cases - Conventional Commits Formatting: Enforces the type/subject/body/footer structure with eight defined types (feat, fix, docs, style, refactor, perf, test, chore). - Japanese Message Rules: Applies strict writing rules including 50-character subject limits, imperative mood, and 72-character body wrapping. - Issue Linking and Signatures: Automatically appends Closes #N references, BREAKING CHANGE footers, and the mandatory Claude Code signature block. - Use Case: After staging changes with git, ask for a commit and receive a properly formatted message like "feat: Docker Composeとuvによる開発環境をセットアップ" with a detailed bulleted body and issue reference, ready to execute via HEREDOC. ## Quick Start Review my staged changes with git status and git diff, then create a commit with a properly formatted Conventional Commits message in Japanese.
