What agents pull and build
It pulled your entire ticketing system. APM data — error rates, latency spikes, drop-off pages. API docs, design system, deployment history, the last 40 pull requests touching that part of the codebase.
Then it talked to other agents. One represented your power user. Another represented the new customer still figuring out onboarding. Another represented the enterprise admin who manages 50 seats and cares about permissions and audit trails. These are not whiteboard personas — they are synthetic users built on your actual usage data.
Output
Code. Not a spec. A working POC tested against synthetic users, iterated four times because the first version failed the enterprise admin's permissions scenario.
The new constraint
The agent found the edge cases your team would have found in QA three weeks from now. Fixed them. Tested again. Passed. The POC is in your product manager's queue. The only question: do we ship this?
The bottleneck is no longer engineering capacity. It is how much change your users can absorb. Ship too fast and your support queue explodes. Rearchitect too often and your integration partners revolt.
New reality
You have never managed this constraint before. Nobody has. The book for this has not been written yet.
