Opportunity Brief

Build a library that translates raw SWE agent traces into multi-step rubric rewards. This allows developers to fine-tune agents using intermediate milestones rather than just pass/fail test results.

Suggested repo: rubricRL

"Stop training your agents on pass/fail—train them on logic."

Estimated effort: 40h
