STaD: Scaffolded Task Design for Identifying Compositional Skill Gaps in LLMs (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing benchmarks often treat complex tasks as monolithic, resulting in inconsistent performance and inconsistent explanations. |
| Approach: | They propose a framework for creating controlled variations of benchmark tasks based on the concept of scaffolding, which introduces structured, incremental support in a step-by-step manner. |
| Outcome: | The proposed framework enables systematic probing of model behavior by identifying the specific reasoning skill compositions they lack. |
