Anthropic Ships Built-In Security Scanner Inside Claude Code — Three-Level Vulnerability Review on Every File Edit
A viral tweet (25 likes, 2,786 views) revealed that Anthropic has shipped a security tool inside Claude Code that 'catches vulnerabilities as they're being written,' described as 'the same security tool they use internally.' The scanner runs at three review levels, with the first triggering on every file edit. This aligns with the broader Claude Security push connected to the Mythos program and positions Claude Code as the first AI coding tool with integrated, always-on security scanning — a differentiator against Cursor, Copilot CLI, and Windsurf.
