Capability-scoped sandbox execution
Capability-scoped execution restricts what an agent can do based on explicit, fine-grained permissions rather than coarse access controls.
Key properties:
- Least privilege by default: Agents start with no permissions
- Explicit grants: Each capability must be explicitly granted
- Auditable boundaries: Every permission grant is logged
- Revocable: Capabilities can be withdrawn at any time
This model mirrors capability-based security systems but applied to agent execution contexts. An agent cannot access a file, network endpoint, or API unless that specific capability has been granted to its execution context.
