The file tab stats the file and mounts its panel without reading it. Every panel, built-in or plugin, gets a PluginFile handle: readText, readBytes, url, version-checked writeText/writeBytes (PluginFileConflictError unless force), and watch. useFileText, useFileBytes and useFileUrl read through it, and Loading joins @getpaseo/plugin/client/ui. Panels own their loading state. The host document pipeline, the explorer preview cache and the preview lifecycle are deleted. The daemon classifies a file version from a bounded sniff and writes base64 content as bytes behind fileByteWrites. A deleted file keeps its panel mounted; a read confirms the deletion first, so a remove-and-rewrite is not reported as one. Native Source decodes with builtins and highlights in idle-time slices, the lines around the opening line first, so a large file no longer blocks the JS thread.
@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.
