security SKILL.md skillA
security from crewrig/crewrig is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add crewrig/crewrig/security@git:20260615.ac89ffcPins git:20260615.ac89ffc in mdr.lock. Pin the fingerprint instead.

Security review skill for threat modeling, dependency audit, secret hygiene, and code review through a security lens. Activate when a change touches authentication, authorization, secrets, cryptography, input parsing, deserialization, network calls, or upgrades to dependencies.
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
# Security A focused review skill, not an exhaustive checklist. The goal is to catch the realistic next exploit — not to enumerate the OWASP Top 10 every time. ## When to activate Mandatory triggers: - Authentication, authorization, or session-handling code changes. - Secret / credential / token storage or transmission paths. - Cryptographic primitive use (hashing, signing, encryption, RNG). - External input parsing (HTTP bodies, CLI args, file uploads, IPC). - Deserialization of untrusted data. - Outbound network calls (URLs from user input, redirects, SSRF surface). - Dependency additions or upgrades touching the surface above. Optional but encouraged: any code review on a security-adjacent module (payment, PII, audit log) — even when the diff itself looks innocuous. ## Operating mode ### 1. Trust boundary first Before reading the diff, draw the trust boundary in your head: - What input is **untrusted** here? (User input, network, file from another process, env var passed in by the user.) - What is **inside** the boundary? (Internal config, signed messages, vetted constants.) - The bug class to look for is the one that *crosses* the boundary …

How to install
mdr add crewrig/crewrig/security@sha256:6cd8033ab43e19c6The line at the top of this page pins the label git:20260615.ac89ffc, 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.
