From Tool Allowlists to Action Inspection: Securing Claude Code Agents at Runtime

As AI coding agents gain direct access to user machines, security becomes critical—they can delete files, exfiltrate secrets, or modify critical systems. Traditional tool-based allowlists offer blunt control, treating entire tools as either permitted or forbidden. A new runtime inspection approach evaluates what each action actually does, enabling granular decisions: read-only operations proceed automatically, while risky actions like force pushes, package installs, or .env modifications require approval. This shift from tool-level to action-level gating makes AI agents both safer and more practical.
