Harness Health Audit
Audit the health of an AI-coding harness — the CLAUDE.md / AGENTS.md files, rules, skills, agents, hooks, and commands that steer an agent in a repository — across four questions a linter cannot answer: is it TRUE (does it match the real code?), is it USED (do skills actually trigger and does the loop actually verify?), is it AFFORDABLE (is it inside the budget where instructions are still followed?), and is it SAFE (is a live, accurate instruction still a good idea — permission bypasses, unpinned remote scripts, untrusted content flowing in as instructions? — safety findings are flagged for the user's decision, never auto-removed). Then surgically correct or remove only what is proven wrong or dead. Use whenever the steering layer may have rotted or may not be working: "하네스 점검해줘", "하네스 드리프트 감사", "CLAUDE.md가 실제랑 맞는지 봐줘", "룰/스킬이 최신인지 확인해줘", "스킬이 제대로 활용되는지 봐줘", "루프 엔지니어링 잘 되고 있는지 검토해줘", "죽은 훅/커맨드 정리해줘", "하네스 안전한지 점검해줘", "audit my harness", "check the rules still match the real stack", "are my skills actually being used", "review the agent loop", "is my harness safe", after a stack or tooling migration, or when onboarding a repo whose steering docs look stale. Not a codebase security audit — it reads the steering layer, not application code. Every finding must be backed by stated-versus-measured evidence; never guess the correct value, and never remove a live path because it merely looks unused.

From the source SKILL.md
A harness is everything that steers an agent but is not the model itself: CLAUDE.md / AGENTS.md at every level, .claude/rules/*.md, skills, subagents, hook wiring, slash commands, and tool/MCP descriptions — plus the .codex / .opencode equivalents when the repo targets several CLIs. LangChain frames it as Agent = Model + Harness, defining the harness as "every piece of code, configuration, and execution logic that isn't the model itself" ([LangChain](https://www.langchain.com/blog/the-anatomy-of-an-agent-harness)); Addy Osmani puts the stakes plainly: "A decent model with a great harness…
What this skill does
Harness Health Audit is a community-contributed Claude Code skill in the forensics sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/harness-health-audit/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use whenever the steering layer may have rotted or may not be working: "하네스 점검해줘", "하네스 드리프트 감사", "CLAUDE.md가 실제랑 맞는지 봐줘", "룰/스킬이 최신인지 확인해줘", "스킬이 제대로 활용되는지 봐줘", "루프 엔지니어링 잘 되고 있는지 검토해줘", "죽은 훅/커맨드 정리해줘", "하네스 안전한지 점검해줘", "audit my harness", "check the rules still match the real stack", "are my skills actually being used", "review the agent loop", "is my harness safe", after a stack or tooling migration, or when onboarding a repo whose steering docs look stale.
Who uses this skill
The Harness Health Audit 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 154,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

When should I use the Harness Health Audit skill?
Use Harness Health Audit when your Claude Code task falls under the Security category — specifically in the forensics area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Harness Health Audit" or describe the task and let Claude pick). Browse related skills at
/category/security/.
What is a Claude Code skill and how does the Harness Health Audit skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Harness Health Audit is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category. Learn more at
