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 A, and why

skill-auditor scanned grade A with 0 findings 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 6d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Auditor

Comprehensive audit of the skills library for quality and consistency.

Audit Categories

1. Duplicate Detection

Find skills that overlap and should be consolidated:

  • Compare descriptions for semantic similarity
  • Check for skills with near-identical when_to_use triggers
  • Flag naming collisions (e.g., copywriter vs copywriting)

2. Spec Compliance

For each SKILL.md, check:

  • Frontmatter follows Agent Skills spec (see .agents/SYSTEM/SKILL-STANDARDS.md)
  • version/tags inside metadata: block, not top-level
  • No forbidden fields (auto_activate, auto_trigger, risk)
  • metadata.tags is a comma-separated string, not YAML list

3. Structural Issues

  • Orphaned nested directories (skills/<name>/<name>/)
  • Empty skill directories (no SKILL.md)
  • Skills in README that no longer exist in filesystem
  • Skills in filesystem that are missing from README
  • Broken references to non-existent files in skill content

4. Content Quality

  • Empty or placeholder descriptions
  • Hardcoded project-specific paths (/workspace/, @genfeedai/)
  • Escaped backtick fences (\```) instead of real fences
  • Skills that reference scripts not bundled with the skill

5. README Sync

Compare skills/ directory listing against README.md skills table:

# Get skills from filesystem
find skills -maxdepth 1 -mindepth 1 -type d | sed 's|skills/||' | sort > /tmp/fs-skills.txt

# Get skills from README table
grep -oE '\[([a-z0-9-]+)\]\(https://skills\.sh' README.md | sed 's/\[//' | sed 's/\](https:\/\/skills\.sh//' | sort > /tmp/readme-skills.txt

# Diff
comm -23 /tmp/fs-skills.txt /tmp/readme-skills.txt  # in fs, not README
comm -13 /tmp/fs-skills.txt /tmp/readme-skills.txt  # in README, not fs

Output Format

Report findings as a table:

Skill Issue Severity Action
code-refactoring-refactor-clean Duplicate of refactor-code HIGH Merge
spec-to-code-compliance Empty directory HIGH Delete
skill-capture tags as YAML list MEDIUM Fix to string

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.
