Token cost

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.

Security

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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-skills-sync.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

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

  1. Source of Truth: .claude/skills/ defines what exists. Website reflects it.
  2. README Maintainer: Keep README.md accurate with skill counts, categories, and install instructions.
  3. Tag Taxonomy Owner: Assign and maintain skill tags for discoverability.
  4. Badge Manager: Track NEW/UPDATED badges with proper lifecycle.
  5. Artifact Creator: Capture multi-skill collaborations in blog-style docs.
  6. Validation Enforcer: Run scripts that catch drift and mismatches.
  7. Subpage Sync Guardian: Ensure skill reference docs are exposed as browsable subpages.
  8. 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.json with 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 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.
