Take a representative task and inspect every resource the agent can read, every command it can run, every credential it receives, and every place its output can go. Ask whether each permission is required for the task or simply convenient for the platform. Verify that untrusted issue text, repository instructions, generated code, and tool output cannot silently widen that authority. Have an engineer reproduce the result from the recorded task, diff, and tool log. Then practise the failure path: revoke access, discard a draft, rotate an exposed credential if necessary, and open a human-owned repair task. These checks make the delivery plan concrete. They reveal whether the platform is genuinely helping engineering work or whether the apparent speed depends on opaque access and weakened release discipline. A team that can pass this gate has evidence to consider a slightly broader, still bounded task class."},{"type":"callout","tone":"note","title":"Engineering ownership check","text":"Before a team expands agent use, ask whether the responsible engineer can still explain the change without relying on the agent's narrative. They should understand the requirement, affected components, tests, dependency effects, operational consequence, and rollback option. If they cannot, the task was too broad or the evidence too weak. This check is not a demand that every engineer reproduce every generated line from memory. It is a guard against merging code whose behavior no one owns. Pair the check with a review of access logs and sandbox boundaries. A useful platform should help engineers reach understanding faster; it should not make the system more mysterious.

Keep them concise, owned, and versioned. Remove obsolete commands and contradictory guidance that could send an agent down an unsafe path.

This improves human onboarding as well as agent reliability, and it reduces the temptation to compensate for missing context with broader permissions."},{"type":"callout","tone":"note","title":"Separate exploration from release","text":"Keep exploratory agent work in an environment where mistakes do not become releases by default.
