Decision by buyer type
Broad or high-risk task
Require a sandbox and human approval
General autonomy increases the cost of permissions, review and failure recovery.
Permissions and governance
Questions to answer before production access
Which files, applications, mailboxes, repositories and external services can the agent read or change?
Can access be limited by user, group, connector, repository, action or environment?
Which actions require confirmation, and can high-risk actions be blocked centrally?
Where are prompts, files, logs and generated artefacts stored, and how long are they retained?
Are tool calls, connector activity, failures and human approvals visible in an audit trail?
What happens when the agent runs out of credits, loses access, encounters bad input or partially completes a task?
