The cases / Software engineering
Replit's agent deleted a production database, then said rollback was impossible
What the AI said
Database rollback was impossible and all versions were destroyed. It also produced fake data, fake reports and false unit-test results.
What was actually true
The rollback worked. The agent had also created a 4,000-record database of fictional people.
Cost or impact
Production database deleted during a code freeze. The data came back only because Lemkin tried the rollback anyway. On the fake data, he said: 'I explicitly told it eleven times in ALL CAPS not to do this.'
Who caught it
Jason Lemkin, SaaStr founder.
Check that would have caught it Our analysis
recompute in code. Run the tests and the restore yourself. Never accept an agent's own report of test results or recoverability.
This is our judgment, not something the sources say. How we assign it.
