Applications (Reranking, Early Stopping, Data Curation)
The core innovation is the conversion of raw human-agent interactions into structured 'segments,' each representing a unit of work. These segments are then densely annotated with Critic Rubrics—24 behavioral features capturing common failure modes, observable directly from interaction traces. This dense supervision, combined with sparse real-world outcomes like PR merge and code survival, enables a powerful semi-supervised learning approach.
This methodology tackles the challenges of noisy, delayed, and sparse feedback inherent in real-world AI systems, transforming previously unusable data into actionable training signals for improved agent performance and scalability.

The rubric-supervised critic achieves a significant boost in task success through best-of-K reranking.
| Metric | Success-Only Critic | Success + Rubrics Critic |
|---|---|---|
| Best@8 Reranking | 63.6% | 73.8% (+10.2 points) |
| Early Stopping Compute Reduction | 70% | 83% |
| Cross-Backbone Robustness | Poor | Good |

The Success + Rubrics approach consistently outperforms Success-Only models, demonstrating superior generalization and practical utility across diverse scenarios. |

Critically, the research shows that critics trained solely on benchmark data do not transfer well to real-world scenarios (AUC 0.45-0.48, near random). This highlights the necessity of real-world interaction data and rubric-based supervision for building robust, deployable AI agents.
The code survival metric proved to be a more fine-grained and reliable signal than PR merge, capturing partial successes and mitigating noise from non-agent factors.
Cross-Backbone Generalization
Problem: Success-Only critics overfit to specific LLM backbones (e.g., Claude Sonnet 4.5), degrading performance on others (e.g., Claude Opus 4.5). This limits their transferability and practical use.
Solution: Rubric-supervised critics learn more backbone-invariant representations of failure modes (e.g., 'incomplete edits,' 'incorrect assumptions'). This allows them to maintain consistent positive gains across different LLM backbones, supporting robust inference-time scaling policies.
Outcome: Rubric-supervised critics achieve an average +15.9 points improvement over random on combined backbones, compared to Success-Only which degrades below random on Opus. This demonstrates their superior generalization and practical utility.
The learned critic operates with significantly lower latency than large language models used for manual annotation, achieving a 16x speedup. This efficiency is crucial for real-time applications such as best-of-K selection and early stopping, where rapid evaluation is essential to reduce computational waste.
Furthermore, critic scores can effectively curate real-world data for supervised fine-tuning (SFT). Critic-selected SFT improves solve rates to 47.8%, demonstrating that predictions from the critic provide actionable signals for identifying beneficial training examples, leading to agent improvement.
