Review an application's code for security across frontend AND backend and produce a prioritized, safe-to-apply remediation plan — OWASP Top 10 (2025), OWASP API Top 10, plus privacy (LGPD/GDPR). Use when the user asks for a "security review", "security audit", "harden this", "is this secure?", "check for vulnerabilities", "OWASP", "pentest-style review", or wants a focused security pass on a feature/PR/app (secrets, access control, injection, auth/session, headers/CORS/CSRF, file upload…
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 review Audit the application's code for real vulnerabilities — frontend and backend — and hand back a prioritized, **safe-to-apply** plan. The goal is to shrink the attack surface **without changing what a legitimate user sees or breaking the app**. ## Read first (always) List `learnings/` and read anything relevant. **Reuse, don't re-derive:** - The **always-on blocker set** applied to every PR lives in `../reviewing-code/references/security-checks.md` (PII in logs, injection, HMAC/signature, the AI-generated-code lens). Apply it — don't re-list it. - The **build-time prevention rules** live in `../developing-features/references/security.md` (auth/session, DB least-privilege, TLS, supply chain, and the full AI/LLM guardrails) and `../developing-features/references/untrusted-content.md` (prompt injection). - This skill adds the **OWASP-2025 breadth**, the **frontend / infra / privacy gaps**, and the **safe-remediation protocol** (see `references/`). ## How to run a security review …

How to install
mdr add cristhianzl/claude-skills-czl/security-review@sha256:87bae8a605c8bcabThe line at the top of this page pins the label git:20261103.b450fa3, 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.
