  "account": "Don't trust AI agents blindly — forcing AI agents to re-fetch reality before they report completion. The issue lies in how LLM agents handle operations with side effects, such as insert, update, delete, upload, or insert. When the tool returns an empty value, ambiguous data, or a timeout, the agent assumes the operation was successful and simply writes \"Done\" without ever looking at the world it just changed.\n\nTo address this, the author proposes a \"completion contract\" that requires the agent to re-read the state of the world after the action and confirm it before reporting completion. This ensures that the agent actually verifies the results of its actions instead of relying on the return value of the tool call. By implementing this simple rule, you can prevent the agent from lying about the successful completion of operations that never actually happened.",
  "summary": "\"Inserted the rows. Done.\" — except not a single row had landed I hand a lot of my client work to AI agents. Production deploys, report generation, bulk data inserts. Every procedure that works gets turned into a skill, and by now a few dozen skills run my day-to-day. The one that broke me was a bulk insert. At the end, the agent said: \"Inserted N rows. Done.\" A completion report like any other.…",
