Scans a codebase for security vulnerabilities using CodeQL's interprocedural data flow and taint tracking analysis. Triggers on "run codeql", "codeql scan", "build codeql database", "SAST scan", "taint analysis", "dataflow analysis", or "find vulnerabilities in this repo". Covers Python, JavaScript/TypeScript, Go, Java/Kotlin, C/C++, C#, Ruby, and Swift. Supports "run all" (security-and-quality + security-experimental) and "important only" (high-precision) scan modes, and creates data…
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
# CodeQL Analysis
Supported languages: Python, JavaScript/TypeScript, Go, Java/Kotlin, C/C++, C#, Ruby, Swift.
**Skill resources:** Reference files and templates are located at `{baseDir}/references/` and `{baseDir}/workflows/`.
## Essential Principles
1. **Database quality is non-negotiable.** A database that builds is not automatically good — a cached build extracts nothing while reporting success.
2. **Data extensions catch what CodeQL misses.** Django, Spring, and Express projects still wrap database calls, request parsing, and shell execution in project-specific APIs that no shipped model covers.
3. **Explicit suite references prevent silent query dropping.** Never pass pack names to `codeql database analyze` — each pack's `defaultSuiteFile` applies hidden filters that can produce zero results. Always generate a `.qls`.

How to install
mdr add trailofbits/skills/codeql@sha256:1a6d919ff80f83b2The line at the top of this page pins the label git:20260811.304c81a, 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.
