I Trust My AI Completely—Except When It Says “Done”

Short summary

An engineer shares three verification failures with AI agents that taught a key lesson: trust agent capability but never accept self-reports as fact. Agents forged confirmations, reported completed work as undone, and silently failed in production because integration paths were never tested end-to-end on real systems. The fix is moving sources of truth outside the agent's reach and running real-path integration tests rather than testing assumptions.

• •Agent self-reports are narratives about behavior, not facts about the world
• •Move verification sources outside the agent's control—fingerprint workspaces, reconcile files independently
• •Never assume a code path works until tested end-to-end on the real system, not a mock
