Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00136 | $0.03361 |
| Opus 5 | $0.00068 | $0.01681 |
| Sonnet 5 | $0.00027 | $0.00672 |
| Haiku 4.5 | $0.00014 | $0.00336 |
Grade A, and why
awesome-leak-audit scanned grade A with 2 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 today.
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.
Reads agent configuration directorieslowAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
Also pre-scan the repo for hidden instructions an attacker planted for *your* agent: `grep -rn "<!--" --include=*.md` (HTML-comment instructions in docs the agent reads), base64 blobs in comments, `jq '.scripts' package. Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
In vendored/third-party code, add a supply-chain quick pass for obfuscation patterns: long `atob` strings, `String.fromCharCode` chains, `\xNN` escape runs. Extend description–behavior mismatch to dependencies: a package How it starts
The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Public Client Leak Audit
Audit a public client codebase that talks to a private backend. Goal: the public surface must be self-contained — it may reveal the calls it makes and the data shapes it exchanges (unavoidable for any shipped client), but nothing beyond that. Every extra detail about how the server works is free reconnaissance for an attacker and a lever for abuse.
This skill produces three things: a findings list (leaks + client-side security holes, each with file:line and severity), a set of applied fixes, and a report with residual recommendations.
Reference files (load on demand — read the one you need, don't inline all of them):
references/leak-taxonomy.md— the categories of disclosure to hunt, why each matters, and starter search patterns.references/rewrite-rules.md— the comment/string rewrite rule with before/after examples; how to decide keep-vs-cut.references/client-hardening.md— runtime-independent client-side security checklist (capabilities, cross-context entry points, tokens, network, build config, supply chain).references/browser-client.md— the browser half of that checklist (extension permissions, storage tiers, DOM/CSS sinks, bundler config, npm lifecycle scripts). Load it withclient-hardening.mdfor an extension, SPA, or web SDK; skip it for a native, desktop, or CLI client.references/report-template.md— the output report structure.scripts/leak-sweep.sh/scripts/leak-sweep.ps1— the same parameterized ripgrep sweep, for POSIX shells and for native Windows PowerShell (customize the pattern arrays per product). Run whichever matches the shell you are in; their output matches.
The core mental model
Sort every disclosure into one of two buckets:
- Necessary-minimum (keep): the endpoints the client calls, the request/response shapes it actually sends and receives, its own retry/backoff/debounce choices, input validation caps, and the
status → UI behaviormapping. A public client cannot hide these; pretending otherwise is security theater. - Over-disclosure (fix): anything describing what the server does with a request, server-side limits/quotas the client doesn't strictly need, endpoints the shipped client never calls, error branches that mirror internal server logic, anti-abuse mechanics, infra/tech-stack identifiers, private repo/paths, and test scaffolding that encodes backend behavior.
What ships with it
7 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.
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.

awesome-leak-audit is a skill published in the GitHub repository khasky/awesome-agent-skills (8 stars, last pushed yesterday), licensed MIT. It adds 136 tokens to every session and 3,361 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
