How It Works

Three-tier hierarchy: Marketplace → Plugin → Components (Skills/Hooks)

1. You add the marketplace (cc-dev-tools) from GitHub
2. You install a plugin (e.g., codex, gemini, or telegram-notifier)
3. The plugin provides components:

- Skills: Invoked by Claude when triggered (codex, gemini) - Hooks: Event-driven automation (telegram-notifier)

Migration from cc-skill-codex

Repository Renamed: This repository was renamed from cc-skill-codex to cc-dev-tools on 2025-11-18.

For existing clones, update your remote URL:

git remote set-url origin [email protected]:Lucklyric/cc-dev-tools.git

GitHub automatically redirects the old URL, so existing clones will continue to work.
