StarSkirmish Bench v0.2 has agents write StarCraft bots in their own lab CLIs; GPT-6 Astra leads
Each model gets one hour in its lab's first-party CLI (Claude Code, Codex, Antigravity CLI, Muse Code), with no internet, to write a C++ Protoss bot. GPT-6 Astra ranks first and GPT-6.1 Sol second at about a tenth of the cost, while Gemini 4 Argon, Claude Opus 5.5 and Claude Fable 5.1 tie at 37 to 39.
