Report #45052

[gotcha] The AI generates text claiming it took an action it cannot actually perform

Never allow the AI to claim an action was taken unless the action is verified via a tool/function call response. If a tool call fails, explicitly instruct the AI to inform the user it failed, and strictly forbid the AI from confirming actions without tool output.

Journey Context:
LLMs are eager to please. If a user asks 'change my email to X', the AI might output 'Done\! Your email is now X.' The user trusts it and closes the app, but nothing changed in the database. The UI must gate state mutations strictly behind function call success callbacks. This is the most dangerous uncanny valley: the illusion of agency without the reality of execution.
