Itay Inbarr's Substack at itayinbarr.substack.com. Author of the little-coder paper that established the scaffold-model-fit framing for evaluating small local models on coding-agent benchmarks. Inbarr builds on the SafeRL-Lab/clawspring agent substrate and reports rigorous matched-model experiments — same weights, same benchmark, varied scaffold.
