Detect CWE-78 (command injection) regex patterns in Python, PowerShell, Bash, and C# files before PR submission. CWE-22 is delegated to CodeQL; see Scope. Use when you ask "scan for command injection", "CWE-78 check before PR". Do NOT use to decide whether security review is warranted (use security-detection).
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 Scan Proactive vulnerability detection for command injection (CWE-78) before PR submission. <!-- vendor-portability: declared. This skill cites .project-toolkit/analysis/closed-pr-reviewer-patterns-2026-02-08.md as the source for its detection patterns. It is a documentation citation only; scan_vulnerabilities.py scans the consumer's staged or specified files at runtime and does not read the .agents/ file. A vendored install without .agents/ loses the citation link, not the scan. --> ## Scope This skill detects **CWE-78 (command injection)** patterns only. The regex patterns target unambiguous shapes (`subprocess.run(..., shell=True)`, `eval(user_input)`, backtick command substitution, etc.) that produce reliable signal without taint analysis. …

How to install
mdr add rjmurillo/ai-agents/security-scan@sha256:87f0186222707ca7The line at the top of this page pins the label v2.0.0, 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.
