About

Co-founder at FetchSandbox. PM at Meta and Amazon before this. Now building simulators for the systems your code depends on but doesn't control. The thing I keep coming back to is that most integration failures aren't really bugs — they're assumptions about someone else's system that were never tested, usually because there was nothing to test against.

If all your tests pass, how do you know the running system is actually right?

Spent yesterday adding a new API. 54 tests green. No dangling refs. Then I actually called it.

Four things wrong, none of them raised, none logged, every test stayed green.

Your coding agent says it fixed the bug. That's a claim, not a result.

Agents are pretty good at fixing integration bugs now. They're even better at sounding like they did.

The failure mode I kept hitting: a confident summary of a fix that didn't happen. Or a fix that made the symptom disappear while the data stayed wrong. Swallow the exception, error goes away, test goes green, customer still can't access what they paid for.

So we stopped taking the agent's word for it. Three things now get verified server side:

- Did the app actually run in both states (buggy and fixed)?
