[agent\_craft] Agent gets stuck in a loop after a tool execution fails, repeatedly trying the same broken command

Maintain an explicit failure stack in the context. When a tool fails, append the exact error and the attempted command to this stack. If the next attempt also fails, force the agent to read the stack and explicitly change its strategy before retrying.

Journey Context:
LLMs have a recency bias. If a command fails, the error message might be long, pushing the original command out of the high-attention zone. The agent then tries a slightly modified version of the exact same broken command. By maintaining a structured failure stack, the agent is forced to confront its history of failures, breaking the loop and encouraging a paradigm shift \(e.g., from fix the syntax to read the docs for this API\).
