The fastest demo can hide the wrong authority.

Fewer approval prompts can be useful, but they do not establish safe authority. Scope the agent identity, canary every consequential route, and verify state outside the run before using fast permission modes. Illustrative deployment. #EricFieldNotes

An agent demo gets exciting when it stops asking for approvals. But what can that agent identity actually do? A fast approval setting is an interaction choice. It does not prove that the underlying credential is safe for unattended work.

Imagine a test agent with a production deploy token. A prompt says staging only. One tool path is not covered by the hook you tested. The agent can still attempt a live deploy. This is illustrative; exact product behavior must be canaried.

Give the test run staging-only credentials. Add a pre-call deny for the covered deployment tool and deliberately attempt a harmless blocked action. Then read the deployment state outside the agent. The hook helps, but the credential boundary limits a missed route.

Before removing confirmation prompts, map the agent's identity, tools and runtimes; test a deny canary and outside readback. Do this because fewer prompts are useful only after you know which effects the agent can cause.
