What you are opening
Use it to install the whole set as one plugin. Each skill also has its own page in this directory if you only need one.
How to set it up
- Add the marketplace, then install the plugin in Claude Code.
- Or run the skills CLI to copy the skills into your agent.
- Start a new session and ask for a spec or a code review.
Requirements and third-party terms
Claude Code with plugin support, or Node.js for the skills CLI. Both install the current default branch rather than the reviewed revision shown below. Listed ≠ audited. Review scripts before running.
Before you add it
- Read the instructions and review any scripts before running them.
- Check tool access, required credentials and third-party network requests.
- The source license and any resource-specific terms take precedence.
