Systematically test a deployed application by going through user flows, trying edge cases, and attempting to break things. Outputs structured bug reports that can be converted to user stories for autonomous fixing.
Test And Break is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/test-and-break/ and loads when your prompt matches the skill's trigger.
The Test And Break Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
