First-time and emerging builders looking for a structured, accessible challenge.

  1. Autonomous Repair of Public-Interest Software

    Build an autonomous agent that ingests an unfamiliar public-interest repository, localizes faults, tests multiple root-cause hypotheses, and produces cause-level patches. Validate every patch with synthesized property-based tests and mutation testing, and include a reviewer-ready explanation.

    Expected outcome
