Phalanx runs parallel-fork CVE remediation on a GitHub repository. Paste a repo URL, and the skill detects critical CVEs in the dependency tree, forks the dependency state N ways via Ghost, validates each hypothesis in isolated InsForge backends, cancels false positives mid-flight via Redis Pub/Sub, converts the Dockerfile to a Chainguard zero-CVE base, and publishes a signed evidence chain to cited.md. Use when the user asks to scan a repository for vulnerabilities, remediate a CVE autonomously, generate an SBOM with attestation, or produce a legally-defensible security remediation record. Also use for keywords like "CVE", "supply chain attack", "dependency audit", "zero-day remediation", "SBOM", "Sigstore", or "security remediation."
