What is security-audit?

A procedure for reviewing a code change or an entire repository for security problems. It checks areas such as committed secrets, package contents, key storage, command execution, CI, and data sent to services.

Use it for a security review of a diff or repository, with findings reported privately when the code is public.

It helps find exposed credentials, unsafe handling of keys, unintended network destinations, and risky build or runtime behavior before release.

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	$0.00063	$0.00195
Opus 5.5	$0.00025	$0.00078
Sonnet 5.5	$0.00013	$0.00039

Security

Grade A, and why

security-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 yesterday.

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 it actually says

security-audit

This skill is a thin wrapper. The procedure lives in a shared, agent-agnostic playbook, so Claude Code, Cursor, Codex and the rest follow the same steps.

Read AGENTS.md (hard rules) if it isn't already in context.
Read and follow docs/playbooks/security-audit.md step by step. It links to the reference docs you need.
Input from the user: $ARGUMENTS

If this wrapper and the playbook ever disagree, the playbook wins. Fix the procedure in the playbook, not here.

Changes

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.
