Breach data answers a question nothing else answers cheaply: which services did this identity actually use. That service list is almost always worth more to an investigator than the credentials in the record — and the credentials are the part you must never touch. Using a leaked password is unauthorized access, no matter how public the dump was.
What Leaked About You is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/what-leaked-about-you/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when checking breach or leak exposure, finding which services an account was registered with, interpreting a combolist or credential dump, assessing credential compromise, or auditing your own leaked personal data. Applies to incident response and account-takeover triage, executive and VIP protection, pre-employment and vendor risk screening, and personal privacy audits.
The What Leaked About You Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 178,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
