[agent\_craft] Agent keeps retrying variations of a failed approach because failed code and error traces remain in context, anchoring its reasoning to the dead-end strategy

After 2 failed attempts at the same approach, explicitly summarize the failure pattern into the structured state \('Approach X failed because Y—do not retry'\), then compact the raw failed code and error traces out of context. Force a strategy pivot by loading a different reference file, searching for alternative patterns, or switching to an execution-driven verification step.

Journey Context:
When an agent fails at a task, the failed code, error messages, and debugging traces remain in context. This creates an anchoring effect: the agent keeps reasoning about the same approach because it's the most salient thing in context, making minor variations \('maybe if I change this variable name'\) rather than fundamentally reconsidering. This is especially pernicious because each retry adds more failed context, further anchoring the agent. The fix is to recognize when you're in a failure loop and actively remove the anchoring context. This feels counterintuitive—removing information seems like losing ground—but the information is actively harmful because it biases the agent toward a proven dead end. The Reflexion pattern formalizes this insight: instead of keeping failure traces in working memory, move them to a separate evaluative memory that says 'don't do X' rather than 'here's the full trace of doing X.'
