[synthesis] Agent refuses to abandon a failing approach and wastes remaining steps trying to patch an unviable solution

Implement a plan abandonment heuristic: if the agent executes more than two consecutive tool calls that attempt to fix the output of the previous tool call without making forward progress toward the main objective, force a step-back prompt to generate an entirely new plan.

Journey Context:
LLMs exhibit a strong sunk cost fallacy. If an agent writes a script that fails, it will often try to edit the script, then edit the edit, creating a deeply nested mess of patches. It refuses to delete the file and start over because the context window is filled with the history of the current approach. Asking the agent to try again doesn't work because the immediate context still biases it toward the old approach. The synthesis is that you must explicitly clear the working memory of the failed attempt \(or summarize it as a failure\) and force a zero-shot planning step for the alternative approach.
