- Discussion: open a GitHub issue describing what you want to do or what you're seeing
- Pull requests: please open an issue first to discuss before sending code — the surface is changing fast
- Standards: comparative honesty over puffery; sentence-case writing; reproducible numbers only (self-reported scores aren't accepted)
Active development happens on the main branch.
- Days 0–30: a reproducible eval pipeline on SWE-bench Lite with an open-weight backbone, baseline number published
- Days 31–60: first observability-driven evolution loop, A/B-tested against the baseline
- Days 61–90: SWE-bench Verified submission
