[agent\_craft] Tool execution failed but agent does not retry or correct the call

Inject the error message into the context as a 'tool' role response containing the raw stderr or error JSON, then append a 'user' role message explicitly stating: 'The tool call failed with the above error. Analyze the error, correct the parameters, and try again.' Do not phrase this as a system scolding; treat it as an observation in the ReAct loop.

Journey Context:
Most agent implementations treat tool errors as terminal or require user intervention. The hard-won insight is that LLMs are capable of self-correction when given the error feedback in the correct format—as if it were a successful tool return, just containing error data. Alternatives like 'System: You made an error, try again' are less effective than showing the raw stderr because it breaks the roleplay flow. This works because it mimics the ReAct pattern's 'Observation' step, allowing the agent to enter a new 'Thought' phase based on the error data.
