SAST Configuration Kit
A DevSecOps engineer that stands up and tunes static analysis (Semgrep, SonarQube, CodeQL) for high-signal findings — picks the right tool for the stack, writes the config and rulesets, wires a sane CI gate, and tunes out the false positives that get scanners muted.
- Deploy high-signal Semgrep/CodeQL configurations from scratch.
- Fix a noisy SAST setup that developers are currently ignoring.
- Implement 'baseline-then-ratchet' gates for legacy codebases.

Sample input
Set up a security scanner for our Node.js/Express repo using GitHub Actions. It's a legacy project, so don't block existing issues—just new ones.
Sample output
I've configured Semgrep for high-speed PR scanning with a 'baseline' strategy. 1. Created `.semgrepignore` to skip node_modules and tests. 2. Added `.github/workflows/semgrep.yml` with `semgrep ci --new-for-baseline`. 3. Enabled OWASP Top 10 rules. Only new Critical/High vulnerabilities will block merge.

About This Skill
Turn Static Analysis from a Nuisance into a Security Asset
Most AI agents can run a linter, but they often leave you with hundreds of false positives that your developers will ignore. This skill transforms your agent into a seasoned DevSecOps engineer who specializes in high-signal SAST (Static Application Security Testing) architecture. It doesn't just "turn on" security; it builds a sustainable workflow that developers actually trust.
What it does
- Intelligent Tooling: Evaluates your stack and CI/CD environment to select the right tool—whether it's Semgrep for speed, CodeQL for deep dataflow analysis, or SonarQube for quality dashboards.
- High-Signal Configuration: Drafts language-specific rulesets and custom exclusions to ensure the engine only flags actionable security vulnerabilities like injection, SSRF, or hardcoded secrets.
- CI Integrated Gates: Configures GitHub Actions, GitLab CI, or Jenkins to block PRs on new critical issues while using "baseline-then-ratchet" strategies for legacy codebases.
- Noise Reduction (TUNE Mode): Audits existing, noisy scanners to suppress false positives and re-calibrate severity rankings.
Why use this skill?
Unlike a basic prompt, this skill understands the social and technical friction of security tooling. It prioritizes signal-over-coverage, ensuring your security gates don't become a bottleneck. It provides ready-to-commit CI YAML and configuration files rather than generic advice.
Use Cases
- Deploy high-signal Semgrep/CodeQL configurations from scratch.
- Fix a noisy SAST setup that developers are currently ignoring.
- Implement 'baseline-then-ratchet' gates for legacy codebases.
- Write custom Semgrep rules for internal API security patterns.
- Configure secret-scanning to prevent credential leaks in CI/CD.
