# CodeQL — Operational Security Analysis Workflow Help coding agents **operate** CodeQL, not just explain syntax. Covers discovery of existing setup, config review, scan execution/inspection, SARIF triage with evidence discipline, remediation, and targeted re-validation. > **Sources:** GitHub Docs Code Scanning with CodeQL (2026-08-12, https://docs.github.com/en/code-security/code-scanning/automatically-scanning-your-code-for-vulnerabilities-and-errors/about-code-scanning-with-codeql), CodeQL CLI (`github/codeql` MIT, CLI binaries separate), `github/codeql-action` (https://github.com/github/codeql-action), and this repo's `.github/workflows/codeql.yml` (Analyze Python via `codeql-action/init@v4` + `analyze@v4`). **Relationship to MegaLinter:** - **MegaLinter:** broad linting/formatting/static quality orchestration (50+ linters, Docker-based, `.mega-linter.yml`, fast feedback on style, config, IaC). - **CodeQL:** semantic security analysis / dataflow / vulnerability classes (source→sink taint, e.g., `python/sql-injection`, `js/xss`, SARIF alerts). - Neither replaces the other. Composition: `code-quality / secure-delivery → { MegaLinter, CodeQL }` without a giant orchestrator. ## When to use - Repo has or needs CodeQL code scanning (`.github/workflows/codeql.yml`, `codeql-action`, SARIF alerts) - Need to triage a CodeQL alert (security tab, SARIF file, CI log) with evidence - Need to fix a finding and re-validate - Workflow failing (timeout, OOM, build failure for compiled
