Description
The paper's signature cross-cutting thesis: frontier coding models converge in capability (top 3 within 1% on SWE-bench), so the operational harness — context management, safety layering, recovery, extension composition — becomes the real differentiator, not the model or the scaffolding. Corollary: the agent loop is easy to copy (a while-true around a model call), but hooks, classifier, compaction, and isolation are not.
Key claims
- The harness is the differentiator; the agent loop is easy to copy
- 20-day retrospective community consensus: the harness is the product
- The harness-is-the-differentiator thesis is the settled community view
