Coherence Collapse: Diagnosing Why Code Agents Fail After Reaching the Right Code
TL;DR
Researchers identified a gap in LLM evaluation benchmarks. They built a synthetic dataset with 10k adversarial prompts targeting reasoning failures.
✦ Why It Matters
Use this benchmark to audit LLM robustness before deploying in production reasoning pipelines.
Key Takeaways
- Analyze agent trajectories to identify failure patterns.
- Implement checkpoints to recover correct code during edits.
- Focus on improving edit quality in code generation.
- Explore reference-free consensus methods for better performance.
How It Works
TRAJEVAL dissects the behavior of code agents into three stages: search, read, and edit. By analyzing these stages, researchers can pinpoint where agents fail, particularly during the editing phase, leading to the discovery of Coherence Collapse.
