Reddit user experiments with failure-learning coding agents to break retry loops

A developer on r/LocalLLaMA has been experimenting with coding agents that learn from failures to break out of repetitive retry loops. The approach focuses on treating failure as reusable information rather than just logging raw errors.

The Problem: Stuck in Failure Loops

The developer observed that coding agents often get stuck in failure patterns: fail → retry → fail again. Initially thought to be a model limitation, the issue appears to be a failure-handling problem where systems don't track why something failed. When retrying, agents typically generate variations of the same attempt, repeating the same mistakes in slightly different ways.

The Experimental Approach

Instead of keeping raw logs, the developer started storing simplified "root causes" and pairing them with fixes that worked previously. Future attempts then match against this stored knowledge rather than guessing again. The developer notes this approach is still rough but shows different behavior: the system doesn't get stuck in the same loops as often and sometimes actually converges on solutions.

Current Challenges

• Matching failures reliably is tricky
• If the system generalizes the wrong thing, it can reinforce bad fixes
• Uncertain how to balance reusing known fixes versus exploring new ones

The developer is seeking community input on this approach and whether others have tried similar methods for improving coding agent failure recovery.
