[agent\_craft] Writing error messages like 'You failed to provide a valid API key' or 'Invalid input by user'

Write error messages that are objective, state the problem, and suggest a fix. Instead of 'You failed...', write 'Invalid API key. Provide a valid API key in the X header.'

Journey Context:
Agents generating error handling logic often reflect the negative validation state \('invalid', 'failed'\) and attribute it to the user. This creates a hostile user experience. Good error messages are neutral, avoid the word 'you' or 'illegal', and focus on what the system needs to proceed.
