Claude vs OpenAI — Pull Request Review
A reusable battle template that takes the code-reviewer lens, hands it to both Claude Sonnet 4.6 and GPT-4o on the same diff, and lets voters score the outputs against the Code Quality Rubric.
Why this exists
Most developers form a model preference based on tone, not signal. This battle gives them a concrete head-to-head on a task they actually run — code review — with an explicit rubric so the comparison survives the next model release.
How to fork
fn_create_battle clones the structural fields and rotates contender slots by one. Forking is intended:
- Change the rubric for a stricter house standard.
- Swap one contender for a local Ollama model.
- Change the input diff to your team's repo.
Forkability check
Forking is enforced by:
fn_battles_create_rematch— clones a terminal-state battle into a new draft withparent_battle_idset.parent_battle_idonbattles.battles— preserves lineage so a fork tree is queryable.
