Report #85460

[agent\_craft] Agent gets stuck in infinite tool error loops

Implement exponential backoff with a 'retry context' that summarizes previous failures; after 2 failures, truncate the detailed error history and inject a meta-summary like 'Previous attempts failed due to X pattern; try alternative approach Y' to force exploration.

Journey Context:
Naive retry loops feed the exact same error message back to the model, causing it to repeat the exact same failed tool call with identical parameters. The fix isn't just adding delays—it's progressive context management. After initial failures, summarize the error patterns and explicitly tell the model 'Previous attempts failed due to X, try Y instead.' This breaks the repetition cycle and forces the agent to explore the solution space rather than exploiting the same failed path. This is critical for autonomous agents running unsupervised tool loops.
