Cross-stack security review — auditing vulnerabilities across infrastructure, smart contracts, CI/CD pipelines, and AI agent systems, plus auth/sessions/crypto and validating user input at API and infrastructure boundaries. Triggers on mentions of "vulnerability", "pentest", "OWASP", "access control", "injection", "CSRF", "JWT", "smart contract audit", "supply chain", "OIDC", or any review of security-sensitive code paths spanning more than one layer. For PII sanitization see…
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 Engineering Cross-stack security rules covering API security, infrastructure hardening, Web3 smart contracts, CI/CD review automation, and agentic AI risks. Aligned to OWASP Top 10:2025, ASVS 5.0, and OWASP Agentic Security Initiative 2026. When reviewing code, think like a senior security researcher: trace user input through to sensitive operations, prefer fail-closed designs, and never trust the client. ## Universal Rules - **Validate every input server-side** with Zod (or equivalent) at the API boundary. - **Parameterize all queries** — Prisma/Drizzle, never string concatenation. - **Authorize on every request** — deny by default, verify ownership. - **Hash passwords with Argon2 or bcrypt** — never MD5/SHA1, never plaintext. - **No hardcoded secrets** — env vars validated at startup, secrets in vault, `.env` in `.gitignore`. - **TLS everywhere**, encryption at rest on all data stores. - **Fail-closed** on auth/permission errors. Never expose stack traces to users. - **Log security events** with sanitization — redact `authorization`, `cookie`, CSRF headers. - **Least-privilege IAM** — scope to specific actions and resource ARNs, not `*`. …

How to install
mdr add lazyisefficient/agentic-os/security-engineering@sha256:c2608fd56dbffdafThe line at the top of this page pins the label git:20261022.3f96b7e, 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.
