Report #4566

[agent\_craft] Writing error messages that state the failure but provide no actionable resolution

Structure error messages to include: What happened, why it happened \(if known\), and what the user should do next to fix it.

Journey Context:
Agents often output raw stack traces or literal error strings \('Error: NullReferenceException'\). This forces the human to do the debugging. A high-signal error message reduces the cognitive gap between failure and recovery, turning a frustrating blocker into a solvable step.
