Runs Snyk CLI security scans and fixes the vulnerabilities found. Covers four domains: source code (SAST via snyk code test), open-source dependencies (SCA via snyk test), container images (snyk container test), and infrastructure-as-code files such as Terraform, Kubernetes YAML, and CloudFormation (snyk iac test). Use this skill whenever the user wants to scan for vulnerabilities, audit dependencies, secure a Dockerfile or container image, check IaC for misconfigurations, or asks "is my code/app/image/infra secure?". Also trigger for requests like "fix security issues", "run a security scan", "check for CVEs", "find hardcoded secrets", or "review my Terraform for security problems" even if Snyk is not mentioned by name.
