Anthropic Launches Claude Security Plugin to Let Claude Review Its Own Code in Terminal Workflow

Anthropic has released the Claude Security plugin in beta, embedding it directly into the Claude Code terminal workflow so developers can scan uncommitted changes or run full repository scans without switching tools. The plugin uses a multi-agent system that reads code, maps architecture, identifies potential threats, and verifies findings to reduce false positives before suggesting style-matched patches. Unlike traditional rule-based scanners, it focuses on cross-file logic issues, memory corruption, injection flaws, authentication bypasses, and complex business logic errors by analyzing Git history and data flows. Early users praise the verification step that builds trust, though Anthropic provides no public false-positive or false-negative statistics yet. The tool deliberately avoids automatic commits, requiring human review for every fix, and integrates with Slack, Jira, CSV, and Markdown exports for existing security workflows. Costs can rise with large scans due to token usage, making incremental or directory-limited scans more practical for teams. Overall, the release represents an effort to add researcher-level AI analysis into daily development cycles as a supplement rather than a replacement for SAST, DAST, or human security teams.
