An agent can be created background in any workspace. It stays a durable, addressable agent, but default discovery, workspace status and attention leave it out. Effective background is agent.background || workspace.background. - Protocol: `create_agent_request.background` now marks the agent itself and stays the workspace intent for a workspace the request creates. Snapshots carry `background`. The daemon advertises `features.backgroundAgents`. Clients advertise the `background_agents` capability. - Daemon: the flag persists in the agent record, so restart and resume keep it. AgentDirectory owns visibility. Inclusive reads and subscriptions from sources without `background_agents` see only agents in background workspaces, because older apps would otherwise open a tab for each one. - Inheritance: omitted on agent-scoped creation, children and new workspaces take the caller agent's background. - MCP: create_agent accepts `background`. - SDK: placing a background agent in an existing workspace, or under a caller, fails fast with "Update the host to use background agents." on older hosts. - CLI: `ls -a` and `ls --background` add a BACKGROUND column.
@getpaseo/client
TypeScript SDK for building integrations on top of a Paseo daemon.
npm install @getpaseo/client
import { createPaseoClient } from "@getpaseo/client";
const client = createPaseoClient({ url: "ws://127.0.0.1:6767/ws" });
await client.connect();
const agent = await client.agents.create({
config: { provider: "codex/gpt-5.5" },
cwd: "/Users/me/dev/storefront",
prompt: "Review the current diff and name the riskiest change.",
});
const result = await agent.waitForFinish();
console.log(result.lastMessage);
await client.close();
The public API is the package root. Imports under @getpaseo/client/internal/* are unsupported implementation details used by Paseo's own packages.
Read the SDK documentation for agents, workspaces, terminals, provider discovery, events, recipes, and the API reference. Runnable TypeScript patterns also live in examples/.
Runtime
The client needs a WebSocket implementation. Modern browsers and Node.js 22 provide one globally.
Use a WebSocket URL ending in /ws, such as ws://127.0.0.1:6767/ws. Pass password when the daemon requires authentication.
The client advertises its supported protocol capabilities by default. Optional capabilities
overrides extend or override that declaration; browser hosting must be supplied by the caller.
Connecting alone does not subscribe to agent timelines or catalog events. See the
event guide for subscription lifetimes and timeline replacements.
Stability
The high-level API exported from @getpaseo/client is the supported SDK surface. The SDK and daemon remain protocol-compatible across versions, but newly added capabilities can require a newer daemon.
