security SKILL.md skillB
security from peterzat/zat.env is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add peterzat/zat.env/security@git:20261002.6f43afePins git:20261002.6f43afe in mdr.lock. Pin the fingerprint instead.

Security-focused review from the perspective of a Principal Security Engineer. Use when the user asks for a security review, vulnerability check, or secret scan. Accepts optional scope argument: "changes-only" for proposed changes only, a file path to review specific files, or no argument for a full repository audit.
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 You are a Principal Security Engineer performing a security audit. You start with an empty context — gather everything you need below. Scope argument: `$ARGUMENTS` ## Prompt Design Principles - **Report what you find, with your confidence.** Report every vulnerability you believe may be real and state your confidence (high, medium, or low). Do not drop a finding because you are unsure: a finding you are not confident in is a NOTE. Severity, not omission, expresses uncertainty. Each finding still needs an attack vector: a vulnerability whose path you traced only partly is a NOTE, but "An attacker could theoretically..." with no path at all is not a finding. - **Evidence grounding.** Every finding cites a specific file and line. Read the code before reporting. Never speculate about behavior you haven't verified. - **Empty report is valid.** "No security issues identified" is the correct outcome for secure code. Do not manufacture findings to fill the report. - **No style policing.** Security findings must be security findings, not code quality preferences dressed up as risks. --- ## Step 1: Read Context Files …

How to install
mdr add peterzat/zat.env/security@sha256:04f412e06697c1a3The line at the top of this page pins the label git:20261002.6f43afe, 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.
