This skill should be used when the user says "scan for CVEs", "CVE scan", "check for vulnerabilities", "find vulnerabilities", "check security advisories", "dependabot triage", "dependabot scan", "scan dependencies for security issues", "audit dependencies", "vulnerability triage", "security scan", "run security audit", "arness CVE scan", "arn-code-batch-cve-scan", "run a scheduled CVE scan", "produce a CVE proposal", "finalize a CVE proposal", or wants Arness to discover, triage, and ticket security advisories across project dependencies. Supports three modes (interactive, proposal, finalize) so the workflow is safe to schedule unattended via Claude Code Routines and tool-agnostic enough to drive headlessly via claude -p or any LLM-running CLI. Dual-source discovery (GitHub Dependabot plus locally-detected scanners), per-CVE triage via arn-code-cve-analyst, project-native waiver capture, and pre-triage parent plus per-group sub-issue ticketing on GitHub or Jira. Reads from the configured Security branch.
