ai-dev-extensions

A curated collection of personal agent extensions, skills, and CLI hooks to enhance AI coding agents like Claude Code, Cursor, Codex, OpenCode, Copilot, and Gemini.

Skills

Each skill lives in its own directory under skills/ with a SKILL.md describing when and how it applies. Browse that folder for the current catalogue — no listing is maintained here to avoid drift.

Git Hooks

Install the git hooks (Conventional Commits validation) into any repo:

/path/to/ai-dev-extensions/hooks/install-hooks /path/to/your/repo

This symlinks commit-msg into your repo's .git/hooks/. Works for all agents and humans alike.
