security is agent-read markdown (skill) from notque/vexjoy-agent: Security: review git changes for vulnerabilities, threat-model a system's attack surface, audit supply-chain risks..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Security Skill
Two modes: **diff review** (scan current git changes for vulnerabilities) and
**threat model** (audit a system's full attack surface). Load the reference for
the mode the request matches.
## Reference Loading Table
| Signal | Load | Why |
|---|---|---|
| Review git changes, scan a diff, check for vulnerabilities | `references/coverage.md` | 40 vulnerability classes for LLM-depth review of changed code |
| Threat model, attack surface, supply-chain audit, deny list, security posture | `references/threat-model.md` | 5-phase threat model workflow with deterministic scripts and artifact gates |
## Default Mode: Diff Review
When the request is about reviewing changes (not a full threat model), run the
diff review directly. This is the common case.
# Security Review Skill
Run a two-layer security review over the current git changes: a deterministic
regex scan for known vulnerability classes, then an LLM-depth Security review of
the diff. Report a single BLOCK / FIX / APPROVE verdict.
**The LLM-depth review runs inside the current Claude session** — the same
subscription that loaded this skill. There is no separate model call, no
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
