Mixtapes

stereOS produces machine images - called **mixtapes** - that bundle a hardened, minimal Linux system with specific AI agent harnesses.

Mixtape	Agent binary	API key
opencode-mixtape	opencode	ANTHROPIC_API_KEY or OPENAI_API_KEY

Each mixtape appends its agent package to `stereos.agent.extraPackages`, which adds the binary to the agent user's restricted PATH. The `-dev` variant of each mixtape includes `profiles/dev.nix` for local SSH key injection.

System

The stereOS system is minimal in nature with several orchestration daemons handling agent lifecycle and acting as a control plane for agent operators:

• admin user and group for administrative operations: /home/admin
• agent user and group for agent to assume: /home/agent/workspace
• `stereosd` - stereOS system daemon
• `agentd` - agent management daemon
