Report #35335

[synthesis] Agent repeatedly retries the exact same failing tool call with no variation, trapped in a sunk-cost loop

Implement a retry counter and a context pivot: if a tool call fails twice, summarize the failure, clear the immediate history, and prompt the agent with a radically different strategy.

Journey Context:
Standard agent loops append errors to the context and ask the agent to try again. However, the presence of the failed attempts in the context anchors the LLM's attention, causing it to slightly rephrase the same flawed approach. The agent is stuck because the context history itself is a local minimum. The fix requires realizing that the context is poisoned by the failure trace and must be abstracted or summarized to break the attention anchor, combining cognitive bias mitigation with context window management.
