security-threat-model
Skill1 starsChanged 2 months agoMPL-2.0View on GitHub
Use when the user asks to threat model a repository, codebase, service, app, component, path, feature, or architecture from an AppSec perspective. Use for repository-grounded threat models that enumerate assets, trust boundaries, entry points, attacker capabilities, abuse paths, mitigations, likelihood, impact, assumptions, and a concise Markdown threat model. Use for prompts like threat model this repo, enumerate abuse paths, identify trust boundaries, model attacker goals, or produce an AppSec threat model. Do not use for general architecture summaries, normal code review, non-security design work, generic security best-practice advice, live incident response, source verification, or ownership/bus-factor analysis. If the primary task is secure coding best practices or a vulnerability report, use security-best-practices. If the primary task is security ownership from git history, use security-ownership-map. If the primary task is an active security or data incident, use crisis-command-center.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
12 rules. 7 are common, 0 are distinctive, and 5 are very specific to this project.
7
Common
Most of the 29 edited versions we read keep these.
0
Distinctive
This author's own choices. Worth a look.
5
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 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
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.
