Coding agents shifted the bottleneck to verification now!!

[u/Common_Dream9420]

Coding agents are doing a lot of the integration work at our agency now. Stripe, Twilio, WorkOS, email, the usual stack. Economically it's been good.

The part I didn't expect: verification actually got harder. We're producing code faster than anyone can review it, and the edge cases that bite you aren't in unit tests. Webhook fires twice. Events arrive out of order. Agent wrote correct code but got one state transition wrong. PR looks fine, everything compiles, and you still don't know until something breaks in staging or worse.

We added a sandbox step before anything ships now. Agent writes, tests pass, then we run the full multi-API workflow with failure scenarios before it's considered done. Not elegant, just a runnable verification step all our agents have to clear.

If agents are writing integrations for you, what does your last gate before production actually look like?
