skill-health-check SKILL.md skillA

skill-health-check from sd0xdev/sd0x-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add sd0xdev/sd0x-harness/skill-health-check@git:20260404.086743b

Pins git:20260404.086743b in mdr.lock. Pin the fingerprint instead.

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.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Skill Health Check

## Trigger

- Keywords: skill health, skill audit, skill lint, check skills, skill quality, validate skills

## When NOT to Use

- Code review (use `/codex-review-fast`)
- Document review (use `/codex-review-doc`)
- Creating new skills (use `skill-creator` plugin, external)
- .claude directory structure check (use `/claude-health`)

## 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.

## Workflow

```
Run automated lint → Review manual dimensions → Produce integrated report → Gate
```

### Step 1: Automated Lint

```bash
node skills/skill-health-check/scripts/skill-lint.js --fix-hint
```

**Script I/O contract:**

| Parameter | Description |
|-----------|-------------|
| `--skills-dir <path>` | Skills directory (default: `./skills`) |
| `--agents-dir <path>` | Agents directory (default: `./agents`) |
| `--json` | Output JSON instead of markdown |

How to install

The exact contents, by fingerprint
mdr add sd0xdev/sd0x-harness/skill-health-check@sha256:9d247204f629ae31

The line at the top of this page pins the label git:20260404.086743b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
