Complete API

View v1.0.1

Specs before providers

Versioned TypeScript contracts and runtime validation keep application code independent of infrastructure.

ReAct + FSM execution

Keep the protected Harness lifecycle separate from the application workflow topology you own.

Every effect is governed

Tools, MCP, memory and external writes pass through policy, trace and Harness boundaries.

Events remain authoritative

Session is a projected product view. Replay and evaluation derive state from the Event stream.

Local-first composition

Start with SQLite, files and deterministic adapters, then replace providers without moving product contracts.

Runnable feature examples

Run 7 isolated feature entries, tour all 15 packages, compile a Domain Pack and submit durable commands.

A framework boundary, not an application template

Hypha supplies contracts and execution boundaries. Your application supplies the Domain Pack, prompts, workflows, capability selections, policies and deployment overlay. The complete API reference documents every public package export, declaration, parameter, return value and member; runnable examples show those APIs in application code.
