What's this about?
ModularRSI evolves five restricted harness modules using 2,000 tasks disjoint from downstream evaluation, reporting transfer to unseen tasks and models (8 HF upvotes).
What exactly is harness evolution?
Changing the agent's loop, tool handling, observations, context management or completion checks rather than retraining the base model. Restricted edits make attribution easier but do not prove safety.
What's the community saying?
8 HF upvotes; author-reported preprint.
- Significance: evaluation-disjoint tasks reduce benchmark-specific tuning.
- Significance: modular edits make improvements easier to attribute.
- Significance: integration conflicts still need verification.
