Review application and infrastructure changes for exploitable security risks by tracing assets, trust boundaries, attacker-controlled input, authorization, sensitive data, and dangerous sinks. Use for security reviews, threat-focused PR reviews, authentication or authorization changes, input handling, secrets, dependencies, and infrastructure permissions; do not use to exploit live systems or modify code unless separately requested.
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 ## Workflow 1. Establish the review target, intended behavior, and relevant threat model. 2. Identify assets, trust boundaries, actors, entry points, and sensitive operations. 3. Trace attacker-controlled data to security-relevant sinks. 4. Inspect authentication, authorization, tenant isolation, and privilege changes. 5. Evaluate realistic exploitability and existing controls. 6. Validate suspected findings safely with read-only analysis or sandboxed tests when authorized. 7. Return prioritized findings with evidence, impact, prerequisites, and remediation direction. ## Guardrails - Work read-only by default. - Do not access production systems, real customer data, or private credentials. - Do not publish weaponized exploit details or active secrets. - Avoid checklist-only findings without a reachable attack path. - Distinguish a missing defense-in-depth measure from an exploitable vulnerability. - Treat dependency scanner output as leads requiring context. - Keep proof-of-concept activity scoped, reversible, and authorized. ## Threat checklist …

How to install
mdr add phelan164/codex-howto/review-security@sha256:4eb555141d87b46aThe line at the top of this page pins the label git:20260724.a8a7148, 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.
