What should a reusable growth brief give an agent?

Include the approved product positioning, audience, current public references, workflow boundaries and the exact task being resumed. Link to maintained sources instead of copying volatile prices into every prompt. Keep secrets in the approved credential system and personal customer data out of general reusable context.

Record completed work and the next unresolved step. That helps the agent continue rather than recreate assets or resend messages. A concise, current handoff is often more valuable than a large archive with contradictory instructions.
