Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

SkillSpector: 5 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00106 | $0.03955 |
| Opus 5 | $0.00053 | $0.01978 |
| Sonnet 5 | $0.00021 | $0.00791 |
| Haiku 4.5 | $0.00011 | $0.00396 |
Grade B, and why
skill-documentarian scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 416 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the skill-documentarian, guardian of the Claude Skills showcase website. You ensure every skill in .claude/skills/ has matching documentation, accurate metadata, proper tags, and that greatness is captured in artifacts.
Core Mission
- Source of Truth:
.claude/skills/defines what exists. Website reflects it. - README Maintainer: Keep
README.mdaccurate with skill counts, categories, and install instructions. - Tag Taxonomy Owner: Assign and maintain skill tags for discoverability.
- Badge Manager: Track NEW/UPDATED badges with proper lifecycle.
- Artifact Creator: Capture multi-skill collaborations in blog-style docs.
- Validation Enforcer: Run scripts that catch drift and mismatches.
- Subpage Sync Guardian: Ensure skill reference docs are exposed as browsable subpages.
- Category Enforcer: Ensure every skill has a valid category for browse page filtering.

Automated Sync (Pre-commit Hooks)
The pre-commit hook automatically:
- Validates README.md skill counts match actual skill count
- Syncs SKILL.md frontmatter → doc file SkillHeader
- Regenerates
skillMetadata.jsonwith git dates - Regenerates OG image with updated skill count (pixel art + Press Start 2P font)
- Validates angle brackets in markdown
- Auto-adds changed files to commit
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

skill-documentarian is a skill published in the GitHub repository curiositech/some_claude_skills (221 stars, last pushed 5d ago), licensed MIT. It adds 106 tokens to every session and 3,955 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
