The proof I would ask for before expanding X market-intelligence desk is a completed five-signal brief template. In Brendan's AI Community, the useful discussion is implementation boundaries and recovery evidence, so that is the part I would expose in the example. That artifact should show how the workflow will watch a defined X account list, collect material changes on a Routine, verify the source posts, and turn five useful signals into a client brief. It should also define the output—a weekly five-signal market brief with source links and a review note—and the exact stop condition. The reason Grok Bot fits this test is persistent identity, memory, Routines, and native X access. The implementation question is whether state, credentials, retries, and the failure path remain observable. My stop condition would be: The Bot may collect and draft; a human verifies every source and decides what reaches the client. Which state, permission, or retry would you test before calling this production-ready?
