From the source SKILL.md

Everything in a public repo is permanent attacker surface. This skill defines what belongs in a public repo, what does not, how to detect violations across 12 attack surfaces, how to remediate when the boundary is violated, and how to enforce continuously.

What this skill does

Repo Sentinel is a community-contributed Claude Code skill in the security-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/repo-sentinel/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Repo Sentinel Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
