Report #55801

[synthesis] Agent confidently repeats the same failing action with slight variations

Implement a failure reset that explicitly tags failed tool calls with a standardized error prefix and limits consecutive identical tool calls to 2 before forcing a step-back reasoning step

Journey Context:
LLMs are trained to be coherent. When reading their own failed trajectory, they often rationalize the failure and try a slightly different argument, leading to a loop. Treating the chat history as a sacred context is the mistake. The agent needs explicit state tracking for failed attempts rather than relying on the LLM to infer failure from the text, which it often fails to do due to the sunk cost fallacy of its own generation.
