Skill8 starsChanged 6 months agoAGPL-3.0View on GitHub

OWASP Top 10 (web, not agentic) baseline review for any web application code change — auth, sessions, headers, CSRF, XSS, SQL injection, CORS, rate limits, secret handling, file upload, SSRF. Use this skill on any PR or diff that touches HTTP handlers, auth flows, session/cookie logic, file uploads, redirect/URL parsing, database queries with user input, or proxying/fetching external URLs. Catches the bug classes that ship to production and become public CVEs. Distinct from the security-auditor agent (which is invoked explicitly); this skill auto-triggers when relevant code is in scope.

The file

Show its rules and text

We split this skill into the rules it gives an agent

15 rules. About 0 are common, 8 are distinctive, and 7 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈8

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 7

    Very specific

    Tied to their project's names, files or tools. Probably skip.

Licensed with conditions — read it at the source. We count its rules but don't quote them. Read them on GitHub.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
