What it does
Skill Health Check is an agent skill from sd0xdev/sd0x-harness. Validate skill quality against routing, progressive loading, and verification criteria. Use when: auditing skills, checking skill health, reviewing skill design. Not for: code review (use codex-code-review) or doc review (use doc-review). Output: health report with per-skill ratings + Gate.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/routing-signature-guide.md` and `scripts/skill-lint.js`).
It sits in Development, covering Code review. The repository describes itself as: The harness layer for Claude Code — a reference implementation of harness engineering with hook-enforced dual review, state-machine gates that survive context compaction, and… The licence is MIT.
When your agent uses it
- : auditing skills
- Checking skill health
- Reviewing skill design
Example prompts
- “/skill-health-check”
Requirements
- Node.js
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Bash(node:*)
Workflow steps
2 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit a4d4bc1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobBash(node:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skill Health Check loads about 1.3k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 78 tokens; SKILL.md has 430 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Core Principle
Skills are on-demand context packages. Their value comes from routing precision (right skill triggers at right time) and context efficiency (minimum tokens for maximum capability). A poorly routed skill wastes context on every mismatch; a well-routed skill transforms a generalist into a specialist at exactly the right moment.

Step 2: Manual Review (when comprehensive audit requested)
Read flagged skills and evaluate:
| Dimension | Question | Rating |
|---|---|---|
| Why > What | Does skill explain underlying principles, not just steps? | ⭐1-5 |
| Scope fitness | Is the skill focused? Could it be split? | ⭐1-5 |
| Progressive loading | Is heavy content in references/, not inline? | ⭐1-5 |
| Routing precision | Would a user's request unambiguously trigger this skill? | ⭐1-5 |
Only run Step 2 when user explicitly requests deep audit. Default: Step 1 only.

Can I use Skill Health Check in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add sd0xdev/sd0x-harness --skill skill-health-check -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/skill-health-check, .gemini/skills/skill-health-check, .github/skills/skill-health-check and .opencode/skills/skill-health-check in your project.
What does Skill Health Check need to run?
Going by SKILL.md and its folder, Skill Health Check needs JavaScript for the scripts in its folder and the command-line tools its instructions call (node). Our summary lists: Node.js. Its frontmatter pre-approves these tools: Read, Grep, Glob, Bash(node:*).
Does Skill Health Check access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Skill Health Check safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Skill Health Check use?
Skill Health Check is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Skill Health Check use?
About 1.3k tokens (SKILL.md is roughly 5.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 562 tokens, read only when the agent opens those files.
What are the alternatives to Skill Health Check?
Skills that share tags, products or a category with Skill Health Check: PR Babysitter (openinterpreter/openinterpreter, 69k stars), Code Review Checklist (shareAI-lab/learn-claude-code, 78k stars), Backend Code Review (langflow-ai/langflow, 155k stars) and Mole Bug Patterns (tw93/Mole, 70k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Skill Health Check?
sd0xdev (a GitHub user) maintains it in sd0xdev/sd0x-harness, which has 192 GitHub stars. The repository holds 89 skills in this directory. The repository was last updated on October 8, 2026.
