How to choose
Pick the failure you want to fix
Some packs target over-engineering, others missing tests or weak reviews. Choose the one that matches what goes wrong for you most often.
Check what it runs
Review and audit skills often ship scripts or hooks. Each page lists them.
Match your agent
Install steps differ by agent. Each page lists the agents the maker names.
Questions
Can I use more than one code quality and testing skill pack at once?
Yes, but start with one. The agent picks a skill by its description, and packs that cover the same job can compete or give conflicting instructions.
Do code quality and testing skills work without Claude Code?
Most do. Skills use an open format that Codex, Cursor, Gemini CLI and other agents also read. Each skill page lists the agents the maker names and the install command for each.
