Ordered authorization rules with immutable policies, typed decisions, and composable conditions

Typed decisions over text. The SDK for decision-machine-1 at milliseconds.ai.

Typed decisions for AI agents as an MCP tool: yes/no probability (noul), choice, and score about JSON state in one fast request, with a fallback envelope that never blocks. Backed by the TypeSafe System One model; shared by pi, Claude Code, and goose.

Typed decisions wired to your code. Asks Jev one calibrated question, calls models through OpenRouter when a node needs to write, draw or look, and emits the graph and the run as JSON.

Small typed decisions for migration and governance pipelines — rule first, then Jev, then Claude Haiku, cached, budgeted and audited
