Windsurf is the agentic IDE acquired by Cognition (the Devin team) in late 2025. The Cascade multi-step engine is genuinely strong — but it is IDE-only, with no standalone CLI or SDK as of May 2026. This puts Windsurf out of scope for IB-CODE-2026.2 (autonomous CLI/API evaluation). When the upcoming IB-CODE-IDE-2026.x rubric launches with human-in-the-loop runs, Windsurf will be a priority subject.
