Report #8149

[agent\_craft] Writing error messages that blame the user \('You failed to provide X'\) or are vague \('Invalid input'\)

Write objective, actionable error messages. State the problem factually and tell the user how to fix it \('X is required. Provide X by doing Y'\).

Journey Context:
Agents often surface raw stack traces or write messages assuming bad intent. Blaming the user creates hostility. The goal of an error message is to get the user out of the broken state as fast as possible, which requires neutral tone and clear next steps.
