An offline audit skill that runs static checks on directories containing skills, agents, or prompt files. It reports critical, major, and minor findings and can optionally prepare a pre-commit hook after asking.

Use it to audit a named directory or the current directory, print the findings, and optionally inspect staged files through a pre-commit hook.

It catches instruction-file problems before they are committed, without relying on runtime behavior or network services. It also makes clear that runtime telemetry cannot be checked by this audit.

Per session 52 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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	$0.00052	$0.00487
Opus 5.5	$0.00021	$0.00195
Sonnet 5.5	$0.00010	$0.00097
Haiku 4.5	$0.00005	$0.00049

Security

Grade A, and why

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 1mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (lib/checks.js, scripts/audit-staged.mjs, scripts/audit.mjs), 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 it actually says

Audit

Run the same static checks the upstream Left the Chat page and its pre-commit hook use, at full local depth, against a directory the user names.

Steps

Ask which directory to audit if not given. Default to the current directory.
Run: node "${CLAUDE_PLUGIN_ROOT}/skills/audit/scripts/audit.mjs" <directory>
Print the output as-is: findings grouped critical, then major, then minor.
If this is the first time this skill has run in this repo, offer to enable a pre-commit hook that calls "${CLAUDE_PLUGIN_ROOT}/skills/audit/scripts/audit-staged.mjs" against files staged in the target repo. Disabled by default. Ask before enabling it; never enable it unasked. A minimal hook body:
```
#!/usr/bin/env bash
node "${CLAUDE_PLUGIN_ROOT}/skills/audit/scripts/audit-staged.mjs" || exit 1
```
Write it to .git/hooks/pre-commit (or a hooks directory pointed at by git config core.hooksPath) in the target repo, and mark it executable.

Notes

This is the static half only. Declared-versus-actual findings (a tool granted but never called, a skill that never fires) need runtime telemetry, which this CLI does not have.
Read-only against the audited files. This skill never edits, moves, or deletes a file in the target repo, other than the hook file it is explicitly asked to write in step 4.
examples/find-ai-events.md (with examples/find-ai-events-fixed.md alongside it as the corrected version) is a task prompt written to trip every PROMPT-* check - useful for seeing the full report shape without writing a prompt from scratch.

Files

What ships with it

3 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.

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.

audit is a skill published in the GitHub repository YoungLeadersDotTech/young-leaders-tech-marketplace (10 stars, last pushed today), licensed MIT. It adds 52 tokens to every session and 487 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-13.
