review-security skillA

review-security is agent-read markdown (skill) from coalesce-labs/catalyst: Security review of a branch's diff against its base for HIGH-CONFIDENCE, exploitable vulnerabilities the change introduces — injection, authentication and authorization bypass, crypto and secrets handling, unsafe deserialization / eval / XSS, sensitive-data exposure — traced from input to sink with the repository's own security patterns as the baseline, reported only at ≥70 confidence with severity, an exploit scenario and a fix, ending in a PASS | FAIL | SKIPPED | UNAVAILABLE verdict with `path.

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 coalesce-labs/catalyst/review-security@git:20260915.10999f5
Exact content
mdr add coalesce-labs/catalyst/review-security@sha256:f509e83455b1c5f5

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.
