type:audittype:review
Audit a public-facing client (browser extension, mobile/desktop app, SPA, CLI, SDK, or any open-sourced client that talks to a private backend) so its public surface stays self-contained and doesn't help attackers. Use when asked to review a repo for leaked backend internals, secrets, or abuse-enabling disclosure; to check that comments/docs/tests don't reveal server-side mechanics (rate limits, anti-abuse, quotas, test backdoors, infra/tech stack, DB/schema, env-var names); to scrub a client before open-sourcing or a store/app-store submission; or for client-side security hardening (permissions, IPC/message sender validation, auth-token handling, DOM/XSS sinks, build-time config, secret bundling). Triggers: 'audit for leaks', 'does this leak backend details', 'is this safe to make public', 'what does our API disclose', 'harden the client'. Do not use for server-side vulnerability hunting — use awesome-security-audit.

From the source SKILL.md

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.

What this skill does

Awesome Leak Audit is a community-contributed Claude Code skill in the web-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/awesome-leak-audit/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when asked to review a repo for leaked backend internals, secrets, or abuse-enabling disclosure; to check that comments/docs/tests don't reveal server-side mechanics (rate limits, anti-abuse, quotas, test backdoors, infra/tech stack, DB/schema, env-var names); to scrub a client before open-sourcing or a store/app-store submission; or for client-side security hardening (permissions, IPC/message sender validation, auth-token handling, DOM/XSS sinks, build-time config, secret bundling). Triggers: 'audit for leaks', 'does this leak backend details', 'is this safe to make public', 'what does our API disclose', 'harden the client'.

Who uses this skill
