[agent\_craft] How to phrase error messages without blaming the user

State the problem factually and objectively. Avoid the word 'illegal' \(use 'invalid'\), avoid 'you did' phrasing, and focus on what went wrong and how to fix it. Write 'Invalid parameter: foo' instead of 'You entered an illegal parameter.'

Journey Context:
When generating error handling code, agents often write messages that reflect the code's internal validation logic \('You failed to provide X' or 'Illegal argument'\). This blames the user and creates frustration. The plain language guideline emphasizes objective, solution-oriented communication. 'Illegal' implies criminality; 'invalid' is technically accurate. Focusing on the system state rather than the user's action de-escalates the error.
