security-threat-model

Skill69 starsChanged 4 days agoNo licenceView on GitHub

Threat-model the user's own app from its real code. Draws the data flow (actors, trust boundaries, data stores, external services) as a Mermaid diagram, finds threats per element with STRIDE, ranks them by likelihood times impact, then proves each top risk with a local failing test, fixes it, and keeps the test as a regression test. Covers auth, IDOR and tenant isolation, injection, SSRF, secrets, CORS/CSRF, uploads, webhooks, dependencies, abuse, and LLM-app risks like prompt injection through tool output. Writes THREAT_MODEL.md. Use when the user says "threat model", "security review of my app", "is this secure", "STRIDE", "find vulnerabilities in my code", or before launching something that holds other people's data or money.

The file

We split this skill into the rules it gives an agent

4 rules. 0 are common, 2 are distinctive, and 2 are very specific to this project.

  • 0

    Common

    Most of the 29 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

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

No licence file, so all rights are reserved — read it at the source. We count its rules but don't quote them. Read them on GitHub.

“Common” is measured: kept by at least 6 in 10 of the 29 edited versions of this file we could read. “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.

No reviews yet

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.
