A checker for Agent Skills: instruction packages containing a SKILL.md file and related scripts or reference files. It looks for formatting errors, broken links, unclear activation instructions, oversized context, exposed secrets, and unsafe code or prompts.

Use it to audit or lint a skill, investigate why it does not activate, check its links and YAML header, and look for secrets or unsafe shell and prompt-injection patterns.

It helps find problems that can stop a skill from activating correctly or make it unsafe to use. It also reduces manual checking across the skill's files.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00094	$0.01030
Opus 5.5	$0.00038	$0.00412
Sonnet 5.5	$0.00019	$0.00206
Haiku 4.5	$0.00009	$0.00103

Security

Grade A, and why

skill-audit 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/audit_skills.py), 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.

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.

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.
