CrewAI

Expose Darwin Search to agents that need discovery. Assign Act thread writes to a role with the required scope and a clear user-approval policy. Store the selected target/capability IDs, threadId, revision, and last consumed cursor in crew state or durable application storage. Do not rely on one agent paraphrasing identifiers for another. Preserve each idempotencyKey for an identical mutation retry. Keep confirmations bound to the exact pending request Darwin returned.

Assign responsibility explicitly

Crew role	Darwin responsibility
Research or planning	Search and explain canonical results
Coordinator	Preserve the user’s selection and durable identifiers
Authorized executor	Invoke allowed thread operations and typed events
Human reviewer	Decide exact approvals and complete sensitive interactions

The handoff between roles should pass structured identifiers, never a paraphrase of the selected capability or approval terms.
