Open-source TypeScript framework where agents and UIs share one set of capabilities
Declare a capability once with defineAction() and it is automatically available to the agent, the React UI, HTTP clients and integrations, eliminating duplicated logic.
The agent sees what users are browsing, selecting and editing, and both read and write the same PostgreSQL database as a single source of truth.
Give agents reusable expertise, persistent context and long-term memory so they stop repeating mistakes and do not need re-explaining.
Run agent work on schedules or in response to events, and delegate to specialist agents within a workspace or across connected agents.

The TypeScript framework for building, deploying, and observing AI agents
Define agents with instructions, models, tools, and runtime behavior, then compose typed workflow steps with retries and branching in TypeScript.
Give agents long-lived context with observational memory, semantic recall, and thread-aware storage.
Traces, metrics, logs, and datasets show every model call, tool call, and handoff in a searchable timeline.
Score agent runs against repeatable checks and experiments before changes reach production.
