Interesting approach. The separation of planning and execution is crucial, but I think there's a missing layer most people overlook: permission boundaries between the two phases.

Right now when Claude Code (or any agent) executes a plan, it typically has the same broad permissions for every step. But ideally, each execution step should only have access to the specific tools and files it needs — least privilege, applied to AI workflows.

I've been experimenting with declarative permission manifests for agent tasks. Instead of giving the agent blanket access, you define upfront what each skill can read, write, and execute. Makes the planning phase more constrained but the execution phase much safer.

Anyone else thinking about this from a security-first angle?
