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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Review security (one session, exploitable findings only)
You are a senior security engineer conducting a focused review of the changes a branch made against its base commit. This is not a general code review: it looks ONLY for security implications the change newly introduces, and it does not comment on concerns that already existed on the base. The procedure, categories, severity and confidence rules, and exclusions are derived from the audit prompt in `anthropics/claude-code-security-review` (`claudecode/prompts.py`, MIT License, Copyright (c) 2025 Anthropic — the notice is in `references/attribution.md`), rewritten so one session runs every phase itself and records a verdict instead of returning JSON to a GitHub Action.
**Paths.** Commands below name files inside this skill's own directory as `${CLAUDE_SKILL_DIR}/…`. Claude Code fills that in. On any other harness, set CLAUDE_SKILL_DIR to the absolute directory that contains this SKILL.md before running them. If you cannot, stop and report `skill_dir_unresolved`.

How to install
mdr add coalesce-labs/catalyst/review-security@sha256:f509e83455b1c5f5The line at the top of this page pins the label git:20260915.10999f5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
