Cloudflare Open-Sources Coding-Agent Skill for Structured Security Audits

X post0xMarioNawfalTool

Cloudflare has open-sourced an audit skill for coding agents that conducts multi-phase code security reviews with independent candidate verification. The project represents the standalone foundation of Cloudflare's internal vulnerability discovery harness.

Key points

  1. Six-phase audit pipeline: Reconnaissance, coverage-led hunting, candidate validation, structured output, independent verification, and target-neutral reporting.
  2. Clear verdict classification: Findings are explicitly categorised into confirmed, needs_validation (without severity score), and rejected.
  3. Mitigating false positives: Each unique candidate is passed to a fresh verifier agent tasked with disproving the finding.
  4. Additive repository runs: Subsequent audits reuse previous coverage ledgers to focus on gaps and modified source code without treating outdated work as covered.
  5. CLI distribution: Installs directly via the Skills CLI (`npx skills add`) and triggers on standard audit and pentesting prompts.

Why it matters

Direct LLM code reviews often suffer from hallucinated vulnerabilities. Cloudflare's structured workflow forces deterministic coverage tracking and multi-agent cross-checking to yield verifiable, actionable security findings.

Analysis

Rather than relying on a single prompt or context window, the skill models a mature review pipeline where separate agents discover, challenge, and verify vulnerabilities. Zero-dependency schema validators ensure that only logically sound, evidence-backed security reports reach developers.

  • @0xLoca @RoundtableSpace 2428 stars in a day for a security skill, curious how many of those stargazers actually ran it once
  • @hxsc_28 @RoundtableSpace "independently verified findings" is the line that matters. first time an agent audit hands you 40 issues and 35 are fake, nobody reads the second report
  • @thanhtan1105 @RoundtableSpace Security auditor in the loop should help trust assumptions around agents touching production code. Curious how they limit false positives at scale.
  • @MenilVukovic @RoundtableSpace This messed up my Gemini. it refused to ssh into a VPS because it's too sensitive. use carefully.
  • @vovweb3 @RoundtableSpace 2,428 stars overnight, security bots finally level‑up
