Cloudflare has open-sourced security-audit-skill under the MIT License on GitHub, releasing the core tool that seeded its own internal vulnerability discovery harness. It enables coding agents to conduct multi-phase security audits with independently verified findings across entire codebases. Rather than relying on unstructured single-turn prompts, it introduces an orchestrated review lifecycle built around agent role segregation and independent re-verification.
Six-Phase Multi-Agent Audit Workflow
The skill guides agents through six distinct phases. First, reconnaissance and codebase mapping catalogs directory layouts and dependencies. Second, coverage-led hunting inspects the codebase area by area to prevent skipped sections. Third, candidate validation by a fresh agent sends each finding to an independent agent to confirm its validity and filter out false positives. Fourth, structured result emission formats findings consistently. Fifth, independent re-verification reviews each record again. Finally, the sixth phase generates the comprehensive audit report.
Triaged Output and Installation Steps
Audit results partition findings into three clear categories: confirmed, needs validation, and rejected. This separation enables developers to resolve verified vulnerabilities immediately while isolating speculative issues. Installation uses npx skills add https://github.com/cloudflare/security-audit-skill --skill security-audit. In a compatible agent environment, entering "security audit this codebase" triggers the full six-phase audit automatically. The agent then autonomously executes all six phases, generating organized vulnerability records ready for engineering review.
Prerequisites and Operational Boundaries
Adopting this workflow requires an agent environment compatible with multi-agent orchestration and dynamic skill installation. Environments without isolated sub-agent capabilities cannot execute the cross-validation architecture. Additionally, findings categorized under 'needs validation' strictly demand secondary manual review by human developers. Automated checks cannot replace human context for complex logic flaws; the skill serves as a productivity harness, not an autonomous replacement for human security expertise.
