Claude skills for debugging: before you install one
Which Claude skill should I use for debugging?
There are 1,009 of them, spread over 373 repositories on GitHub. Named for it and most starred: debugging and error recovery (addyosmani/agent-skills, ★ 112k), debugging (code-yeongyu/oh-my-openagent, ★ 70k) and agent qa debug fix (sickn33/agentic-awesome-skills, ★ 49k). Stars rate the repository a skill sits in, not the skill.
How do I install a Claude skill for debugging?
For debugging, take the debugging-and-error-recovery folder from addyosmani/agent-skills (the folder that holds SKILL.md) into ~/.claude/skills/ to use it in every Claude Code project, or into .claude/skills/ for one project. In the Claude apps, zip that folder and upload it as a custom skill in settings.
What should I check before installing a debugging skill?
A debugging skill is instructions Claude follows, and it can bundle scripts Claude runs, so read SKILL.md and every script first: for debugging and error recovery, that is everything in the debugging-and-error-recovery folder. Red flags: piping a download into a shell, sending files to a URL, and instructions to hide what it does from you.
Are these debugging skills maintained?
632 of the 1,009 debugging skills sit in repositories that changed in the 30 days before 31 Oct 2026.
Is there an official Anthropic skill for debugging?
Yes: webapp testing comes from Anthropic's own skills repository. The other 1,008 are community-made.
Can I use these debugging skills at work?
Of the 50 debugging skills listed here, 40 sit in repositories under an open licence such as MIT or Apache 2.0, and testdriver:debugging with screenshots states no licence at all, which legally means you may not reuse it. Check the licence file before you copy one into company work.
