# Agent, crew, and tool problems

Reduce an agent or crew failure to one selected definition, one permitted tool, and one reproducible input.

- Confirm the active agent or crew and its published configuration.

- Check that the required model tier, skill, tool, plugin, or connection is available to the account.

- Review the task’s autonomy mode and any waiting approval card.

- Run one harmless tool action outside the full workflow.

- Read the first failed tool card, including target, status, and error, before retrying.




A model response is not proof that device tools are connected, and a healthy tool catalog is not proof that the selected agent may use it. For a crew, test the failing member directly before changing routing for every member.




**Expected result:** the isolated action succeeds or identifies the exact entitlement, permission, configuration, or tool boundary.
