The core lifecycle tools (submit_goal, execute_run, execute_task, list_tasks, get_task_evidence, get_run) are reasonably distinct, but the surface contains explicit duplicates: get_pending_approvals vs list_pending_actions and reject_approval vs reject_action are the same operation, and the six 'legacy helper' agent/session tools overlap conceptually with the new run/task tools. The 'Legacy' labels in descriptions help an agent pick the modern path, but they do not remove the redundancy.

Nearly everything follows a snake_case verb_noun pattern (submit_goal, list_tasks, cancel_run, get_model_usage), which is predictable and readable. Minor deviations like wait_for_idle and get_agent_status, plus vocabulary drift between 'agent', 'session', 'run', and 'task' for related concepts, keep it from a perfect score.

20 tools is heavy for the apparent scope, and roughly a third of them (spawn_agent, send_message, wait_for_idle, get_agent_status, list_agents, kill_agent, reject_action, list_pending_actions) are deprecated legacy duplicates or aliases rather than new capability. The set would be better scoped near a dozen tools without the legacy tail.

The goal-to-run-to-task-to-evidence lifecycle, cancellation, approvals listing, model discovery, skills, and usage accounting are covered. However, the approval workflow is one-sided: there is get_pending_approvals and reject_approval but no tool to approve an action, which is a hard dead end under CHAT_APPROVAL mode, and there is no retry/resume for a failed task.
