security skillA

security is agent-read markdown (skill) from prabhdeepsingh/claude-plugins: Build-time security discipline — threat-model before controls, Always/Ask-First/Never boundary tiers, SSRF, supply chain, LLM/agent security, privacy. INVOKE PROACTIVELY when building anything touching auth, user data, uploads, outbound fetches, dependencies, or model output — even when nobody says "security". The after-the-fact review pass belongs to /security-review; validation mechanics: [[code-standards]]; infra secrets: [[infra-standards]]..

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.

How to install

Latest version
mdr add prabhdeepsingh/claude-plugins/security@git:20260913.4e5ade4

mdr add prabhdeepsingh/claude-plugins/security@sha256:d501a85eff88d7ea

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.
