Anthropic drops free security plugin for Claude Code

Shifting security left directly into the AI terminal is a smart move that prevents the model from generating vulnerabilities in the first place.

• –The plugin intercepts write and edit operations to catch issues before code is applied.
• –Teams can enforce organization-wide standards by defining custom rules in a claude-security-guidance.md file.
• –Operating locally via regex, the free plugin catches low-hanging fruit without adding roundtrip latency to the coding loop.
