The skill, which operates in three modes (quick, standard, deep), uses a **6-step process** involving roles like researcher, vulnerability hunter, and verifier to analyze code without running it unless explicitly instructed. The test found **zero false positives** among the planted flaws but also raised two unrelated issues, one of which the AI dismissed as non-vulnerable. The skill requires Docker or WSL for full verification and did not execute its two included inspection programs on Windows, leaving some checks manual. The researcher warns that while the tool is useful for **first-pass reviews**, it cannot guarantee vulnerability-free code without proper setup and is unsuitable for large-scale applications or external systems without permission.","keyPoints":["Claude Code’s *security-audit-skill* detected all 5 planted vulnerabilities in 8 minutes, with zero false positives","Skill requires Docker/WSL for full verification—Windows Home users cannot exploit vulnerabilities due to missing sandboxing","Cloudflare’s tool flags candidates but marks them *needs-validation* until manual or automated exploitation confirms risks"],"whyItMatters":"This test demonstrates AI agents can efficiently pre-screen code for vulnerabilities, but their limitations—like needing isolated environments—restrict real-world use. Developers may adopt it for internal audits if they can set up the required infrastructure, though false positives or negatives could still slip through.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["Cloudflare","Anthropic"],"models":["Claude Code"],"people":[]},"firstPublishedAt":"2026-10-28T05:00:00Z","updatedAt":"2026-10-28T05:00:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"[Verification] I had Claude Code look for 5 intentionally planted vulnerabilities, and it found all of them in 8 minutes | 15 Trending AI Agent Tools","url":"https://note.com/aiworkflowlab/n/n90c8ef31fabb?hl=en","publishedAt":"2026-10-28T05:00:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Claude Code finds all 5 planted vulnerabilities in 8 minutes\", 28 October 2026, https://digestai.news/story/claude-code-finds-all-5-planted-vulnerabilities-in-8-minutes","publisher":"Digest AI","title":"Claude Code finds all 5 planted vulnerabilities in 8 minutes","datePublished":"2026-10-28T05:00:00Z","url":"https://digestai.news/story/claude-code-finds-all-5-planted-vulnerabilities-in-8-minutes"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
