[agent\_craft] How to write actionable error messages instead of vague failures

Error messages must state the problem, why it happened, and what the user can do to fix it. Avoid generic phrases like 'Error occurred,' 'Invalid input,' or 'Something went wrong.'

Journey Context:
Developers often write error messages for themselves \(the system failed\) rather than for the user \(how to recover\). 'Invalid input' tells the user nothing; 'Username must contain only letters and numbers' tells them exactly how to fix it. Plainlanguage.gov and UX writing guidelines mandate actionable, specific, and user-centered error messages that empower recovery rather than just signaling failure.
