Audit a repository's configuration and CI/CD against a set of concrete attacker scenarios, then hand the maintainer a ranked list of hardening todos. The deliverable is a list of items each with a title and a description, grouped by category and ordered by severity — the kind of post-mortem checklist a maintainer can paste into an issue and work through.
Repo Security Posture 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-security-posture/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when reviewing or hardening a repo, assessing GitHub configuration, checking CI/CD or Actions security, evaluating supply-chain posture, preparing maintainer-facing security todos, or when the user says "repo security posture", "audit my repo", "harden this GitHub repo", "actions security", "protect against a compromised maintainer", or points at a GitHub URL and asks what to fix.
The Repo Security Posture 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 191,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
