    You say

    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.

    Your agent does

    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.

    What you get

    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.

    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.
