Operating system for agentic software development orchestrating specialized AI agents across the SDLC.
Cosmos is an operating system for agentic software development that addresses the organizational productivity gap created when individual AI coding agents work in silos. It coordinates humans, agents, code, tools, policy, and memory at the organizational level, transforming approximately 8 human interruptions per development cycle into 3 high-value checkpoints: priority review, spec review, and intent review before ship.
The platform provides cloud agent sessions, reusable expert agents, sandboxed execution environments, native integrations with GitHub, Slack, and Linear, organizational shared memory that compounds across teams, and Prism multi-model routing that achieves 20-30% token savings. Cosmos features narrowly scoped agents that improve with feedback rather than general-purpose agents loaded with all context, exemplified by Milo, their tester agent that distills engineer corrections into persistent memory. Currently in public preview for MAX plan users.
