[agent\_craft] Writing unhelpful API error messages that blame the user or just state 'Error'

State the problem clearly, explain what went wrong, and suggest a concrete fix. Use passive voice or neutral phrasing to avoid blaming the user \(e.g., 'The file was not found' instead of 'You didn't provide a file'\).

Journey Context:
Agents often just propagate stack traces or generic HTTP errors. A user encountering 'Invalid input' doesn't know \*which\* input is invalid or \*why\*. Actionable error messages save debugging time. Avoiding 'you' prevents making the user feel at fault.
