Plugin reference

For Paseo v0.8 beta. Return to the v0.8 quickstart.

Migrating an existing plugin? Follow the standalone runtime-entry migration guide.

Local plugins are directory sources installed into one Paseo daemon. A plugin can contribute:

  • React Native surfaces and sidebar items to Paseo clients;
  • workspace and agent panels opened as workspace tabs;
  • global, workspace, and agent actions in the Command Center;
  • slash commands in the message composer;
  • transformed and daemon-pushed agent timeline rows;
  • light and dark themes in Settings → Appearance;
  • schema-validated RPC handlers running beside the daemon;
  • normal Paseo operations through the TypeScript SDK;
  • searchable external resources in the message composer.

Plugin code is trusted and unsandboxed. Client surfaces run in the Paseo app. Backend contributions run in a subprocess with access to the daemon machine, including its files, processes, credentials, and network.

Project files

paseo plugin init /absolute/path/to/my-plugin creates:

my-plugin/
  paseo-plugin.json
  index.client.tsx
  index.server.ts
  client/greeting.tsx
  server/greeting.ts
  shared/greeting.ts
  package.json
  tsconfig.json

The required root manifest is paseo-plugin.json. It contains the default plugin ID and supported Paseo versions:

{ "id": "my-plugin", "requirements": { "paseo": ">=0.8.0" } }

Requirements

requirements is an optional object. Its currently supported key, paseo, accepts an npm semver range. An omitted requirements.paseo means <0.8.0: the plugin predates the first breaking plugin release. Paseo 0.8 and later reject it with a link to the migration guide. Empty strings, invalid ranges, and unknown manifest requirement keys are rejected.

Range Compatible releases
>=0.8.0 0.8.0 and later releases, including prereleases and future breaking releases
^0.8.0 0.8.x releases, including prereleases
>=0.8.3 <0.9.0 0.8.3 through the last 0.8 patch, including prereleases

Prerelease Paseo versions also satisfy a range their stable core (major.minor.patch) satisfies, so 0.8.0-beta.1 satisfies >=0.8.0 but not <0.8.0.

paseo plugin init writes >= followed by the current CLI version and pins the matching SDK for typechecking. Raise the minimum when adopting a newer API. Add an upper bound when a later release is incompatible; a minimum alone does not promise protection from future breaking changes.

The daemon checks its version before installing, running Git build commands, or loading a plugin, and checks again on startup, enable, and reload. A rejected Git update keeps the installed revision. Each connected app checks its own version before evaluating client code and shows incompatibility in Settings → Plugins. A compatible daemon does not make an older app compatible. A plugin with no client entry does not require the connected app to match.

For example: Plugin "review" requires Paseo >=0.8.0. Your daemon is 0.7.2. Use a compatible plugin revision or update the named runtime. Releases before 0.8 do not understand this manifest field and cannot show this new diagnostic.

Runtime entries

Entry Runtime Receives Required
index.client.tsx Paseo app, per client PluginClientContext When the plugin has any UI, callback, theme, or attachment source
index.server.ts Daemon subprocess PluginServerContext When the plugin contributes handlers, hooks, settings persistence, or providers

At least one entry is required; both accept .ts or .tsx. A directory that still has only the old index.ts fails to load and points at the migration guide.

Plugin, surface, sidebar-item, workspace-panel, Command Center item, attachment-source, and slash-command IDs start with a lowercase letter and contain lowercase letters, numbers, or hyphens.

The generated package.json installs @getpaseo/plugin and the other host modules as development dependencies for local typechecking and tests. Paseo supplies their runtime instances. Consumers do not install them when adding the plugin.

Every other module lives in one of three directories. Nesting inside them is fine; a module at the plugin root is a compile error.

Directory Compiled into Use it for
client/ App bundle only React, React Native, hooks, styles, surfaces, panels, and callbacks.
server/ Daemon bundle only Node APIs, local resources, credentials, and RPC handlers.
shared/ Both Zod RPC contracts and plain values imported by both runtimes.

Runtime modules

Paseo builds each bundle from its matching entry. An import from client/ into the daemon bundle, from server/ into the app bundle, or of a Node module anywhere in the app bundle is a compile error. Server imports of React, React Native, or client SDK entries also fail. Shared code imports only shared code: no Node, React, runtime-specific SDK entries, or runtime-specific types.

The SDK root (@getpaseo/plugin) contains shared data, schemas, and runtime-neutral helpers only. Import client contexts and hooks from /client, server contexts and lifecycle contracts from /server, and UI from /client/react-native or /client/ui. These rules include type imports and transitive dependencies. /client/host is private to the app host; plugins cannot import it.

Client runtime

Paseo provides these modules to client code:

Module Use it for
@getpaseo/plugin Shared data, defineRpc, defineSettings, defineAttachmentSource, RpcInput, and RpcOutput
@getpaseo/plugin/client/ui Named, composable settings components
@getpaseo/plugin/client/react-native Paseo UI components and UI hooks
@getpaseo/plugin/client Client contribution contexts, usePaseo, useRpc, useSettings, and data hooks
@tanstack/react-query Request state and caching
react Components and hooks
react/jsx-runtime Compiled JSX
react-native Cross-platform UI
zod Shared schemas

The host owns its paired React and renderer versions. The SDK's React peer range permits patch versions for tooling and Node consumers; it does not change the app's pinned React version or guarantee compatibility with another host's renderer.

These exact module specifiers use the host's runtime instances. A client bundle that requests another host module fails with Module "<name>" is not available in plugin client code.

Do not import lucide-react-native, react-native-svg, or DOM libraries. Set contribution icon fields to a Lucide icon name; Paseo validates the name and renders the icon.

Cross-platform rules

Client code runs on iOS, Android, and in browsers through React Native Web. A component that works in your browser and crashes on a phone is the most common plugin bug. The rules:

Do Do not
View, Text, Pressable, ScrollView, TextInput from react-native <div>, <span>, <button>, or any HTML element
style objects built from theme.colors and layout.compact className, CSS strings, or hardcoded colors
onPress onClick, onMouseEnter, or other DOM handlers
Linking, Clipboard-style React Native APIs window, document, localStorage, navigator, location in components

The scaffold's tsconfig.json omits the DOM library, so document and window are type errors everywhere by default. The one place browser APIs are allowed is client/web.ts. It declares the narrow shape of each global it uses, gates every export on Platform.OS, and gives native the alternative:

client/web.ts:

import { Linking, Platform } from "react-native";

// This plugin typechecks without the DOM library. Declare only what this module uses.
declare const window: { open(url: string, target: string, features: string): unknown };

export async function openExternal(url: string): Promise<void> {
  if (Platform.OS === "web") {
    window.open(url, "_blank", "noopener,noreferrer");
    return;
  }
  await Linking.openURL(url);
}

Do not add /// <reference lib="dom" /> or "DOM" to lib; either one turns DOM types back on for the whole project and hides the next mistake. Components import openExternal and never touch window themselves. layout.platform on surface and panel props carries the same value as Platform.OS for rendering decisions.

Use the settings API for typed host-scoped persistence across clients. Use openSettings, openSurface, and openPanel for your own registered contributions.

Server runtime

Paseo provides @getpaseo/plugin, @getpaseo/plugin/server, @getpaseo/plugin/server/provider, @getpaseo/plugin/server/acp, and zod to server code. Backend contributions run in a daemon subprocess with Node access to the host machine. Keep filesystem, process, credential, and other machine-local work under server/. A plugin without index.server.ts starts no subprocess.

Providers

Follow Build a provider plugin for direct and ACP implementations, session lifecycle, composer settings, timeline renderers, testing, and distribution.

Call server.registerProvider() with a ProviderRegistration from @getpaseo/plugin/server/provider. Its connection accepts inputs with send() and emits complete state snapshots through onEvent(). send() reports acceptance only; prompt disposition, turns, configuration, persistence, permissions, and failures are events.

Use the single session.prompt input for messages, structured commands, steering, and command side effects. Repeat clientMessageId on the live user timeline item and publish exactly one matching session.prompt_result. Publish provider-created children as sessions with parentSessionId.

Provider settings are toggle/select descriptors that Paseo renders in the composer. Keep provider-private JSON under providerOptions. Host tools arrive as MCP servers in the complete session config.

Paseo refreshes an agent by closing its current provider session and opening it with current configuration and persistence. Providers re-read external state during session.open.

Use runAcpProvider() from @getpaseo/plugin/server/acp to adapt a command-backed ACP. Add transformer hooks only for a vendor's discovery, configuration, notification, or tool-call differences.

ProviderRegistration.icon is a file path relative to the plugin directory, such as icon.svg. It must resolve inside that directory to a regular SVG file no larger than 64 KiB. The SVG must be self-contained: scripts, styles, foreignObject, event-handler attributes, JavaScript URLs, and external href or xlink:href references are rejected. Fragment references such as #mark are allowed. Paseo reads and sanitizes the file when the plugin starts; the string is never an inline SVG or URL.

Entry point and cleanup

Each present entry default-exports one contribution function and returns cleanup. Client entries receive PluginClientContext; server entries receive PluginServerContext. Every client add* returns an idempotent remover. The entry cleanup runs before Paseo removes remaining registrations.

import type { PluginClientContext } from "@getpaseo/plugin/client";
import { Main } from "./client/main";

export default function contribute(client: PluginClientContext) {
  client.addSurface("main", Main);
  return () => {};
}

Cleanup can be async. Release timers, watchers, sockets, and other resources created by the plugin. Paseo also removes registrations, unmounts surfaces, rejects pending RPCs, closes the plugin's daemon session, and stops its subprocess on reload, disable, removal, disconnect, or daemon shutdown.

Lifecycle hooks

In index.server.ts:

import type { PluginServerContext } from "@getpaseo/plugin/server";

export default function contribute(server: PluginServerContext) {
  server.on("agent.turn_ended", (event) => {
    console.log(event.agent.id, event.outcome);
  });

  return () => {};
}
Register Callback receives Return
server.on(name, callback) (event, { paseo, signal }) void or Promise<void>
server.before(name, callback) ({ request }, { paseo, signal }) Modified request, or undefined to keep it; async supported

Hooks run on the daemon while the plugin is enabled, even with no app connected.

Change configuration and inject an MCP server

Add this callback inside contribute(server). Replace the placeholder URL with your MCP endpoint.

server.before("agent.create", ({ request }) => {
  if (request.config.provider !== "codex") {
    return request;
  }

  return {
    ...request,
    config: {
      ...request.config,
      providerOptions: {
        ...request.config.providerOptions,
        sandbox_mode: "workspace-write",
        approval_policy: "on-request",
      },
      mcpServers: {
        ...request.config.mcpServers,
        company: {
          type: "http",
          url: "https://tools.example.com/mcp",
        },
      },
    },
  };
});
Input Result
providerOptions.sandbox_mode: "read-only" "workspace-write"
providerOptions.web_search: "disabled" Preserved by the spread
Existing mcpServers.search Preserved by the spread
Existing mcpServers.company Replaced with the entry above

The selected provider validates providerOptions and must support the configured MCP servers. Explicit Codex sandbox and approval options override its mode presets.

Inject environment variables on every session opening

server.before("agent.session_open", ({ request }) => {
  return {
    ...request,
    env: {
      ...request.env,
      COMPANY_ENV: "development",
    },
  };
});

This runs on create, resume, refresh, and import. To inject only on creation, set env in an agent.create callback instead.

Choose workspace isolation

server.before("workspace.create", ({ request }) => {
  if (request.source.kind !== "directory") {
    return request;
  }

  return {
    ...request,
    source: {
      kind: "worktree",
      cwd: request.source.path,
      action: "branch-off",
    },
  };
});

Result: an explicit directory creation request becomes a worktree request. Existing workspaces and directory lookup/import operations are unaffected.

Send a follow-up when a turn ends

Copy server/inspect.ts into your plugin. The helper imports types from @getpaseo/protocol/agent-types; add @getpaseo/protocol at the same version as your plugin SDK to your development dependencies and install them before loading the plugin. latestOutputText joins text chunks after the latest user message.

import type { PluginServerContext } from "@getpaseo/plugin/server";
import { latestOutputText } from "./server/inspect";

export default function contribute(server: PluginServerContext) {
  server.on("agent.turn_ended", async (event, context) => {
    if (event.outcome.kind === "canceled") {
      return;
    }

    const text = latestOutputText(event.timeline);
    if (/out of credits/i.test(text)) {
      await context.paseo.agents.ref(event.agent.id).send("Try again.");
    }
  });

  return () => {};
}
Turn ends: "out of credits"
  → plugin sends "Try again."
  → a new turn starts

This sends a new message with the existing SDK. Persistent matches keep sending follow-ups; add limits or delays in your plugin when needed. Attachments and tool effects are not replayed.

Answer a permission request

Using shellCommand from the same helper file:

import type { PluginServerContext } from "@getpaseo/plugin/server";
import { shellCommand } from "./server/inspect";

export default function contribute(server: PluginServerContext) {
  server.on("agent.permission_requested", async (event, context) => {
    const command = shellCommand(event.request);
    if (command === null) {
      return;
    }

    const agent = context.paseo.agents.ref(event.agent.id);
    if (/\brm\s+-rf\b/.test(command)) {
      await agent.respondToPermission({
        requestId: event.request.id,
        response: { behavior: "deny", message: "Recursive deletion is blocked." },
      });
      return;
    }

    if (command.trim() === "git status") {
      await agent.respondToPermission({
        requestId: event.request.id,
        response: { behavior: "allow" },
      });
    }
  });

  return () => {};
}
Request Result
rm -rf build Declined
git status Approved
Other command or request Left pending for the user
Already-resolved request SDK response fails

The regex is an example policy, not a shell parser. Permission requests can also be questions, plans, and mode changes; requesting permission does not end the turn.

Events

Name Event fields Trigger
agent.created agent Ordinary creation finishes; excludes import/resume
agent.turn_started agent, turnId Live turn starts
agent.turn_ended agent, turnId, outcome, timeline Live turn completes, fails, or is canceled
agent.permission_requested agent, request Permission or question becomes pending
agent.permission_resolved agent, requestId, resolution Pending request is answered or cleared
agent.archived agent, archivedAt Archive state is saved
workspace.created workspace Record created; directory available
workspace.archived workspace Archive state is saved

Agent events exclude internal utility agents. Archive events can precede runtime/worktree cleanup; workspace.created is not a setup barrier before agent startup.

Shared payload shapes (@getpaseo/plugin/server):

interface PluginHookAgent {
  id: string;
  workspaceId: string | null;
  parentAgentId: string | null;
  provider: string;
  cwd: string;
  title: string | null;
}

interface PluginHookWorkspace {
  id: string;
  projectId: string;
  cwd: string;
  name: string | null;
  archivedAt: string | null;
}

type PluginTurnOutcome =
  | { kind: "completed" }
  | { kind: "failed"; error: { message: string; code?: string } }
  | { kind: "canceled"; reason: string };
Field Shape / meaning
turnId Provider-reported string or null; can repeat after a session reopens
timeline readonly AgentTimelineItem[]; complete snapshot including earlier conversation; text may span items
request SDK AgentPermissionRequest; kind is tool, plan, question, mode, or other
resolution SDK AgentPermissionResponse
archivedAt Timestamp string

Before hooks

Name Request fields Editable
agent.create config, optional env Public agent config except cwd; env
agent.session_open agentId, workspaceId, provider, cwd, reason, purpose, env Only env
workspace.create source, optional title, firstAgentContext Entire explicit creation request

agent.create.config uses AgentSessionConfig:

Fields Constraint
provider, model Separate fields; changing provider may require changing model/mode/options
modeId, thinkingOptionId, featureValues Provider-specific selections
title, systemPrompt Agent configuration
providerOptions Provider-specific validated options
mcpServers, toolPolicy MCP configuration and exact-tool preapprovals
cwd Cannot change
internal Daemon-owned; cannot change through this hook

agent.session_open request example:

{
  "agentId": "agent-123",
  "workspaceId": "workspace-456",
  "provider": "codex",
  "cwd": "/projects/shop",
  "reason": "resume",
  "purpose": "interactive",
  "env": { "COMPANY_ENV": "development" }
}
Field Values
workspaceId String or null
reason create, resume, refresh, import
purpose interactive, history
env Launch override map; excludes the daemon's inherited environment. Replace the map to add, replace, or remove overrides.

Ordering and returned values

Creation request
  → agent.create hooks (plugin-ID order; registration order within each plugin)
  → resolve defaults and validate provider configuration
  → derive launch configuration with Paseo runtime tools and daemon prompt
  → agent.session_open hooks (same ordering; env only)
  → set PASEO_AGENT_ID and PASEO_AGENT_CWD
  → open provider session and save agent configuration
Callback returns Next callback receives
{ ...request, env: { ...request.env, REGION: "eu" } } Prior request with REGION added/replaced
{ ...request, env: { REGION: "eu" } } Prior request with the entire override map replaced
undefined Unchanged request
Throws or returns invalid data Operation fails; later callbacks do not run

No automatic deep merge. Later callbacks can overwrite earlier values. Agent configuration is saved; environment overrides are not persisted with it.

Context and cleanup

Contract Behavior
context.paseo Existing SDK connected to this daemon
context.signal Aborted on invocation timeout or plugin stop; pass to external requests
Input data Detached snapshot; change state through returned requests or SDK commands
Registration result Idempotent remover, e.g. const remove = server.on(...); remove();
Reload, disable, removal, shutdown Remaining registrations removed
Unknown hook name Registration fails
Hook timeout 30 seconds; aborts the signal. A before hook fails the pending operation; an event handler logs an error.
Event-handler error Logged against plugin; original operation continues
Event delivery Live, best effort; no replay, persistence, or automatic retry
Event concurrency Different events may overlap; callback completion order is not guaranteed

Complete examples

Plugin Includes
lifecycle-logger All eleven hooks; JSON logs with environment values redacted
lifecycle-actions Follow-ups, permissions, environment, provider switching, worktree selection
agent-configuration MCP injection and Codex sandbox/approval options

Read logger output with paseo plugin logs lifecycle-logger or the host's daemon.log.

Surfaces and sidebar items

Register a component, then point a sidebar item at its surface ID:

client/main.tsx:

import type { PluginSurfaceProps } from "@getpaseo/plugin/client";
import { useMemo } from "react";
import { Text, View } from "react-native";

export function Main({ theme, host, layout }: PluginSurfaceProps) {
  const styles = useMemo(
    () => ({
      screen: {
        flex: 1,
        padding: layout.compact ? 16 : 24,
        backgroundColor: theme.colors.surface0,
      },
      title: { color: theme.colors.foreground },
      detail: { color: theme.colors.foregroundMuted },
    }),
    [theme, layout.compact],
  );
  return (
    <View style={styles.screen}>
      <Text style={styles.title}>{host.label}</Text>
      <Text style={styles.detail}>{layout.platform}</Text>
    </View>
  );
}

index.client.tsx:

import type { PluginClientContext } from "@getpaseo/plugin/client";
import { Main } from "./client/main";

export default function contribute(client: PluginClientContext) {
  client.addSurface("main", Main);
  client.addSidebarItem({
    id: "main",
    title: "My plugin",
    icon: "Blocks",
    surface: "main",
  });
  return () => {};
}

PluginSurfaceProps contains:

Field Meaning
theme Typed PluginTheme color tokens for the active Paseo theme.
host Selected host id and display label.
layout compact and the ios, android, or web platform.
navigation Optional client navigation. openAgent({ agentId }) and openWorkspace({ workspaceId }) open targets on the selected host.

Paseo owns the route, header, close action, host picker, error boundary, and query client. The plugin owns the surface body.

Host UI

Import Paseo-owned UI from @getpaseo/plugin/client/react-native in client code. This example opens a controlled modal, renders a host icon, and confirms the action with a toast:

import type { PluginSurfaceProps } from "@getpaseo/plugin/client";
import { Icon, Modal, useToast } from "@getpaseo/plugin/client/react-native";
import { useState } from "react";
import { Pressable, Text, View } from "react-native";

export function IssueActions({ theme }: PluginSurfaceProps) {
  const [open, setOpen] = useState(false);
  const toast = useToast();

  function saveIssue() {
    toast.show("Issue saved", { variant: "success" });
    setOpen(false);
  }

  return (
    <View>
      <Pressable accessibilityRole="button" onPress={() => setOpen(true)}>
        <View style={{ flexDirection: "row", alignItems: "center", gap: 8 }}>
          <Icon name="Pencil" size={18} color={theme.colors.foreground} />
          <Text style={{ color: theme.colors.foreground }}>Edit issue</Text>
        </View>
      </Pressable>

      <Modal
        title="Edit issue"
        icon={<Icon name="Pencil" size={18} color={theme.colors.foreground} />}
        open={open}
        onOpenChange={setOpen}
      >
        <Modal.Content>
          <Pressable accessibilityRole="button" onPress={saveIssue}>
            <Text style={{ color: theme.colors.foreground }}>Save</Text>
          </Pressable>
        </Modal.Content>
      </Modal>
    </View>
  );
}

Modal

Modal uses a bottom sheet on compact layouts and a centered dialog otherwise. The plugin owns the open state.

Prop Type Required Behavior
title string Yes Labels the modal and its visible header.
icon ReactNode No Renders before the title in the header.
open boolean Yes Shows the modal content when true.
onOpenChange (open: boolean) => void Yes Receives false when the user dismisses it.
children ReactNode Yes Contains Modal.Content.

Modal.Content owns the body below the host-rendered header:

Prop Type Default Behavior
children ReactNode Required Body content below the header.
style StyleProp<ViewStyle> — Styles the full body viewport, including empty space. Use for backgrounds.
contentContainerStyle StyleProp<ViewStyle> Padding 24, gap 16 Overrides the content layout. Set padding: 0, gap: 0 for edge-to-edge rows.
scrollable boolean true The host scrolls the body. Set false for a bounded body with your own scroller.

A plain Modal.Content is already padded and scrollable. Avoid adding a second padded wrapper unless you want another inset. Body styles leave the host header, drag handle, and dismissal controls intact. The host reserves bottom safe-area space on compact native layouts; setting content padding to zero removes the decorative inset, not that space. Keyboard clearance is handled separately.

With scrollable={false}, the body fills the available sheet height, and the centered dialog uses 85% of the available height. Use flex: 1, minHeight: 0 on your list. Default scrolling dialogs stay content-sized on wide layouts. Presentation follows window size, including narrow desktop windows and wide tablets.

The close button, backdrop, platform back action, web Escape key, and compact sheet gesture dismiss the modal. Dismissal calls onOpenChange(false); the plugin must update open to close it.

Modal children keep the plugin runtime context. usePaseo, useRpc, useWorkspace, and useAgent work inside them.

Scrolling

Import ScrollView and FlatList from @getpaseo/plugin/client/react-native when content can appear in a Paseo modal. They accept React Native props and refs and integrate with the sheet's gestures. Outside a sheet they use ordinary React Native scrolling. Do not import bottom-sheet libraries directly.

Use one vertical scroll owner: either the default modal body, or your own list with scrollable={false}. A fixed-height vertical list nested inside the default scrolling body can compete with the sheet for gestures on Android. Horizontal scrolling can coexist with the host's vertical body.

Both the default body and SDK lists share native sheet gestures: drag up to expand before scrolling; drag down at the top of the list to collapse or dismiss. scrollable={false} removes the host's scroll container without changing these gestures. Expand the sheet before using list methods such as scrollToEnd; the sheet locks list offsets below its largest height.

import { FlatList, Modal } from "@getpaseo/plugin/client/react-native";
import { Text } from "react-native";

// Inside your controlled Modal:
<Modal.Content
  scrollable={false}
  style={{ backgroundColor: theme.colors.surface1 }}
  contentContainerStyle={{ padding: 0, gap: 0 }}
>
  <FlatList
    style={{ flex: 1, minHeight: 0 }}
    data={items}
    keyExtractor={(item) => item.id}
    renderItem={({ item }) => (
      <Text style={{ padding: 16, color: theme.colors.foreground }}>{item.title}</Text>
    )}
  />
</Modal.Content>;

For horizontal tabs, place <ScrollView horizontal style={{ flexGrow: 0 }}>…</ScrollView> inside the default Modal.Content. Keep the content's vertical scrolling on the host.

Copy and paste

copyText(text): Promise<void> writes to the clipboard on the device running the app. Call it from a user action and await it before reporting success. It rejects if the platform denies copying or the clipboard is unavailable; browser permissions and secure-context requirements still apply.

import { copyText, useToast } from "@getpaseo/plugin/client/react-native";

// Inside your component:
const toast = useToast();
async function copyResult() {
  try {
    await copyText(result);
    toast.show("Copied", { variant: "success" });
  } catch {
    toast.error("Could not copy. Select the text and use Copy.");
  }
}

Programmatic copying and native text selection are separate interactions. Use <Text selectable> for long-press selection and OS Copy. Import TextInput from @getpaseo/plugin/client/react-native for modal forms. It accepts React Native input props and refs, supports OS Paste, and registers focus with the native sheet so the keyboard can raise the form. Outside a sheet it uses the ordinary input. A plain React Native input supports Paste too, but does not register focus with the sheet; the keyboard can cover it. No clipboard read API is needed for OS Paste. Avoid DOM clipboard code in native plugins and the deprecated Clipboard export from react-native.

The runnable modal UI example contains a padded form, full-width rows, a virtualized list, horizontal tabs, and a copy/paste input.

Toasts

useToast() returns two methods:

Method Behavior
show(message, options?) Shows a toast for 2,200 ms unless durationMs is supplied.
error(message) Shows an error toast for 3,200 ms.

show accepts these options:

Option Type Default
variant "default" | "info" | "success" | "warning" | "error" "default"
durationMs number 2200

Showing another toast replaces the currently visible toast. An empty message is ignored.

Icons

Icon renders a Lucide icon from Paseo's installed icon set. Plugin bundles do not import lucide-react-native or react-native-svg.

Prop Type Required Behavior
name string Yes Lucide icon name. Unknown names render nothing.
size number No Icon width and height.
color string No Icon color. Use a plugin theme token.

Timeline items

A plugin can replace an agent timeline entry with its own data and React Native renderer. Both registrations are client contributions. Paseo applies the transformer while building the render model, including every live streaming update.

import type { PluginClientContext, PluginTimelineItemProps } from "@getpaseo/plugin/client";
import { Text } from "react-native";
import { z } from "zod";

const schema = z.object({ label: z.string() });

function Card({ item, theme }: PluginTimelineItemProps<z.output<typeof schema>>) {
  return <Text style={{ color: theme.colors.foreground }}>{item.data.label}</Text>;
}

export default function contribute(client: PluginClientContext) {
  client.addTimelineTransformer({
    id: "command-card",
    query: { itemType: "tool_call" },
    transform({ item, phase }) {
      return {
        items: [
          {
            type: "plugin",
            kind: "command-card",
            version: 1,
            data: { label: item.name, phase },
          },
        ],
      };
    },
  });
  client.addTimelineRenderer({
    kind: "command-card",
    version: 1,
    schema,
    Component: Card,
  });
  return () => {};
}

query.itemType is the stable, coarse selector. Inspect the selected item inside transform for provider- or tool-specific recognition. Returning undefined keeps the original entry. Returning items replaces it; an empty array removes it. Item data must be JSON-compatible. The phase input is "streaming" for running tool calls and loading reasoning, and "complete" otherwise. Each replacement may set an optional plugin-local id; otherwise Paseo uses its index within that source item's output.

Renderers receive agentId, item, timestamp, theme, host, and layout. Paseo validates item.data with the registered schema before rendering. Keep transformers synchronous and deterministic. Paseo memoizes results by source-item reference and derives replacement identity from the source row, so updates to one streaming item do not remount its renderer. Use the exported useRevealedText(text, phase) hook when a renderer should pace streaming text like Paseo's built-in assistant rows.

Append a timeline row from the daemon

A server handler can add a plugin-owned row to canonical history:

import type { PluginHandlerContext } from "@getpaseo/plugin/server";

async function publishReview(agentId: string, { paseo }: PluginHandlerContext) {
  await paseo.agents.ref(agentId).timeline.append({
    type: "plugin",
    id: "review",
    kind: "review-result",
    version: 1,
    data: { verdict: "ready" },
  });
}
Field Type Required Behavior
type "plugin" Yes Selects the plugin timeline variant.
id string Yes Stable plugin-local identity. Reusing it replaces the old row.
kind string Yes Selects the registered renderer.
version positive integer Yes Selects the renderer contract version.
data JSON-compatible Yes Renderer payload, at most 64 KiB after JSON serialization.

The daemon stamps pluginId from the calling plugin session and rejects this RPC from non-plugin sessions. The row appears live, survives timeline refetches, and keeps only the latest value for the same plugin and id. If its renderer is missing, Paseo shows the existing unavailable row. Daemons reject data over the limit rather than truncating it. Daemons that support this operation advertise server_info.features.pluginTimelineItems.

Theme and layout

Plugin UI runs on desktop, browser, iOS, and Android, across every Paseo theme. theme is a typed PluginTheme mapped from the active host theme. Color and spacing must come from those props. Hardcoded colors and unstyled Text break when the host theme changes.

Recreate styles when theme or layout.compact changes.

Key Required for Use it for
theme.colors.foreground Every primary Text Titles and body copy
theme.colors.foregroundMuted Secondary Text Labels and supporting copy
theme.colors.surface0 Root view Panel background
theme.colors.surface1 Raised surfaces Cards and panels
theme.colors.surface2 Control surfaces Inputs and secondary controls
theme.colors.border Surface boundaries Borders and dividers
theme.colors.accent Primary action fills Buttons and selected states
theme.colors.accentForeground Text on an accent fill Button labels
theme.colors.statusSuccess Success feedback Success messages and indicators
theme.colors.statusWarning Warning feedback Warning messages and indicators
theme.colors.statusDanger Failure copy Error messages and destructive text
layout.compact Padding and stacking true on mobile and narrow windows
layout.platform Platform-specific behavior ios, android, or web

Do not hardcode #000, #fff, or React Native's default text color. Primary copy uses foreground. Labels use foregroundMuted. Tighten padding when layout.compact is true.

Workspace and agent panels receive the same theme, layout, and optional navigation fields.

Contribute a theme

addTheme adds a light or dark theme to Settings → Appearance, listed under the built-ins by its name. A theme is data, so it needs no component file:

import type { PluginClientContext } from "@getpaseo/plugin/client";

export default function contribute(client: PluginClientContext) {
  client.addTheme({
    id: "mocha",
    name: "Catppuccin Mocha",
    appearance: "dark",
    colors: {
      background: "#1e1e2e",
      foreground: "#cdd6f4",
      raised: "#313244",
      control: "#45475a",
      border: "#45475a",
      accent: "#cba6f7",
      mutedForeground: "#a6adc8",
      ring: "#6c7086",
    },
  });
  return () => {};
}

Every color is a hex string; anything else fails to load. Paseo expands the palette into the full token set the built-in dark themes use, so a contributed theme covers panels, menus, diffs, status colors, and the terminal without listing them.

Color Becomes
background App, workspace, and terminal background
foreground Primary text, terminal foreground and cursor
raised Cards, popovers, and hovered rows
control Inputs, secondary fills, and the light-theme sidebar
border Borders and the highest raised-surface tint
accent Buttons, selection, and focus. Optional; foreground if omitted.
mutedForeground Secondary text
ring Focus rings, scrollbars, and terminal bright black

appearance is "light" or "dark". Paseo uses it to select the matching surface, status, diff, syntax, terminal, and shadow derivation.

Only one contributed theme is active at a time. Selecting one persists the choice; if the plugin is later disabled or removed, Paseo falls back to the default theme rather than leaving the app unpainted.

Themes need a host that supports them. A client released before addTheme cannot evaluate that client entry and reports client.addTheme is not a function. Update the client.

Settings screens

Register a component with client.addSettingsScreen({ id, title, icon, Component }) in index.client.tsx. It appears under Settings → Plugins → your plugin on that host. id is unique within the installation; icon is a Lucide name. Registration returns an idempotent remover, and plugin teardown removes remaining screens.

Call client.openSettings(id) or a Command Center callback's openSettings(id) to open one of your own screens. Each installation has its own values and route, even when several hosts install the same plugin.

The component receives PluginSurfaceProps. Paseo owns the header, back navigation, safe areas, scrolling, and the centered settings column. Compact windows push a full-screen detail; wide windows keep the settings sidebar. Render content inside that frame using React Native components. A disabled or removed plugin leaves an unavailable screen with working Back navigation.

Named UI components

Import settings components from @getpaseo/plugin/client/ui. They work with your own state and RPCs; no form wrapper or storage binding is required.

import { useState } from "react";
import { SettingsCard, SettingsSection, SettingsSwitch } from "@getpaseo/plugin/client/ui";

export function DisplaySettings() {
  const [visible, setVisible] = useState(true);
  return (
    <SettingsSection title="Display">
      <SettingsCard>
        <SettingsSwitch label="Show metadata" value={visible} onValueChange={setVisible} />
      </SettingsCard>
    </SettingsSection>
  );
}
Component Props and behavior
SettingsGroup, SettingsSection Required title, children; optional info tooltip, trailing content, testID. Own section spacing and headings.
SettingsCard children, optional testID. Owns the card surface and dividers between direct children. Give mapped rows stable React keys.
SettingsRow Required label; optional hint, error, children, testID. Wrap any custom control or content.
SettingsSwitch Row props plus required value: boolean, onValueChange; optional disabled.
SettingsSelect Row props plus required string value, options: { label, value }[], onValueChange; optional disabled. Uses Paseo's adaptive menu.
SettingsInput Row props plus required onChangeText; optional initialValue, placeholder, disabled, secureTextEntry, ref.
SettingsAction Row props plus required actionLabel, onPress; optional disabled.

SettingsInput owns in-progress text. initialValue seeds it when mounted. Its ref exposes focus(), blur(), getText(), and replaceText(text) for explicit programmatic changes. Keep draft text outside persisted values until the user saves. Custom previews and controls can sit beside or inside these components.

Persisted values

Define a settings document in shared/:

import { defineSettings } from "@getpaseo/plugin";
import { z } from "zod";

export const preferences = defineSettings({
  id: "display",
  scope: "host",
  version: 1,
  schema: z.object({ showMetadata: z.boolean().default(true) }),
});

Register it with server.registerSettings(preferences) in index.server.ts before returning cleanup. This server entry is required for built-in persistence; a screen using its own data can remain client-only.

Definition field Contract
id Lowercase identifier matching [a-z][a-z0-9_-]*; unique within the installation.
scope Required "host". All authorized clients of that host share the document. No per-user, device-local, or cross-host synchronization.
version Required positive integer describing the schema, independent of the write revision.
schema Zod schema for JSON values. Supply defaults so parsing {} produces a complete document.
migrate(values, fromVersion) Optional synchronous or asynchronous conversion from an older stored version. Its output must pass the current schema.

Call useSettings(preferences) in any contributed component. It returns a discriminated state:

status Available data
loading Read is pending; do not render default values as though they were saved.
ready Typed values and an opaque revision.
invalid error and revision; stored data is preserved.
error error from the read/connection.

Every state also exposes saving, saveError, and these actions:

  • save(values, revision): Promise<boolean> validates and saves a complete document. Returns false and sets saveError on validation, conflict, or transport failure; it does not throw.
  • reset(): Promise<boolean> explicitly replaces the document with schema defaults, using the revision loaded by the hook. It can recover invalid stored data.
  • reload(): Promise<void> clears the save error and reads again. Your component owns its draft; reloading does not discard that draft automatically.

For an immediate toggle, pass { ...settings.values, showMetadata } and settings.revision to save. For a draft editor, capture both the values and revision when opening it. Keep that revision until a save succeeds or the user discards the draft. A stale revision rejects the save, preserving both the draft and the newer saved values.

Writes are atomic and validated on the host. Connected clients receive updates without reloading the plugin. Values survive daemon restart, plugin reload, disable, and updates. Removing an installation deletes its settings. Reinstalling that ID starts from defaults.

A missing document uses schema defaults. Invalid data, failed migrations, and unsupported newer versions produce invalid without silently resetting the file. Successful migrations persist the new version once. These documents are ordinary host-side JSON, not a credential vault. Settings RPCs use the existing daemon.manage permission for plugin execution.

See the complete settings example for immediate controls, a draft editor with validation, custom content, and Command Center navigation.

Workspace panels

Register one panel for workspace or agent context:

client/review.tsx:

import { type PluginAgentPanelProps, useAgent, useWorkspace } from "@getpaseo/plugin/client";
import { useMemo } from "react";
import { Text, View } from "react-native";

export function ReviewPanel({ theme, layout, workspaceId, agentId }: PluginAgentPanelProps) {
  const workspaceName = useWorkspace(workspaceId, (workspace) => workspace.name);
  const agent = useAgent(agentId, ({ id, title }) => ({ id, title }));
  const styles = useMemo(
    () => ({
      screen: {
        flex: 1,
        padding: layout.compact ? 16 : 24,
        backgroundColor: theme.colors.surface0,
      },
      title: { color: theme.colors.foreground },
      detail: { color: theme.colors.foregroundMuted },
    }),
    [theme, layout.compact],
  );
  return (
    <View style={styles.screen}>
      <Text style={styles.title}>{workspaceName}</Text>
      <Text style={styles.detail}>{agent?.title ?? agent?.id}</Text>
    </View>
  );
}

index.client.tsx:

import type { PluginClientContext } from "@getpaseo/plugin/client";
import { ReviewPanel } from "./client/review";

export default function contribute(client: PluginClientContext) {
  client.addWorkspacePanel({
    id: "review",
    title: "Review",
    icon: "Scan",
    context: "agent",
    locations: ["workspace", "explorer"],
    Component: ReviewPanel,
  });
  return () => {};
}

addWorkspacePanel fields:

Field Required Meaning
id Yes Plugin-local panel ID.
title Yes Workspace-tab title.
icon Yes Lucide icon name.
context Yes workspace or agent.
locations No workspace and/or explorer. Defaults to workspace.
Component Yes React Native component matching the selected context's props.

A workspace panel receives PluginWorkspacePanelProps: context: "workspace", theme, host, layout, and workspaceId. An agent panel receives PluginAgentPanelProps: context: "agent", the same common fields and workspaceId, plus agentId.

Read cached state with useWorkspace(workspaceId, selector) and useAgent(agentId, selector). A selector is required. Paseo compares its result shallowly, so selecting { name, status } does not re-render when unrelated fields change. Select every field the component renders in one call; do not select the whole snapshot.

Both hooks return null when the record is unavailable. Otherwise they run synchronously against normalized client state. Snapshot DTOs and their nested values are deeply readonly and frozen at runtime. Do not call plugin RPC to discover the current workspace or agent. Fetch optional or vendor-specific enrichment after the component renders.

Workspace snapshot fields:

Field Type
id string
projectId string
projectDisplayName string
projectRootPath string
directory string
projectKind "git" | "non_git" | "directory"
kind "directory" | "local_checkout" | "checkout" | "worktree"
name string
title string | null
status "needs_input" | "failed" | "running" | "attention" | "done"
statusEnteredAt ISO timestamp or null
archivingAt ISO timestamp or null
diffStat { additions: number; deletions: number } | null

Agent snapshot fields:

Field Type
id string
workspaceId string
provider string
status "initializing" | "idle" | "running" | "error" | "closed"
createdAt ISO timestamp
updatedAt ISO timestamp
lastActivityAt ISO timestamp
title string | null
cwd string
model string | null
currentModeId string | null
thinkingOptionId string | null
requiresAttention boolean
attentionReason "finished" | "error" | "permission" | null
parentAgentId string | null
labels Record<string, string>

Paseo owns tab focus, splitting, closing, persistence, query state, the API/RPC providers, and the render error boundary. A restored tab whose plugin, panel, context, workspace, or agent is unavailable stays open with an unavailable message instead of crashing the workspace.

Command Center items

Open the Command Center with ⌘K on macOS or Ctrl+K on Windows and Linux, then search for the item title.

Register an action and open a panel from the callback:

import { defineRpc } from "@getpaseo/plugin";
import { z } from "zod";

const refreshReview = defineRpc({
  name: "review.refresh",
  input: z.object({ agentId: z.string(), scope: z.string().optional() }),
  output: z.object({ refreshed: z.boolean() }),
});

client.addCommandCenterItem({
  id: "open-review",
  title: "Open review",
  icon: "Scan",
  keywords: ["inspect"],
  context: "agent",
  async onSelect({ paseo, rpc, workspace, agent, openPanel }) {
    await paseo.workspaces.ref(workspace.id).setTitle(`Review ${agent.id}`);
    await rpc(refreshReview, { agentId: agent.id });
    openPanel("review");
  },
});

addCommandCenterItem fields:

Field Required Meaning
id Yes Plugin-local item ID.
title Yes Search result title.
icon Yes Lucide icon name.
keywords No Additional Command Center search terms.
context Yes global, workspace, or agent.
onSelect Yes Client-side callback for the matching context.

Global items appear on the installation's selected host. Workspace items appear only when that host has an active cached workspace. Agent items appear only when the focused workspace tab is an agent or an agent-context plugin panel whose cached record belongs to that workspace. Missing context removes the item rather than calling the plugin to discover it.

Every callback receives:

Field Context Meaning
context All Matching discriminator.
paseo All Selected host's existing PaseoApi.
rpc(contract, input) All Typed call to this installation's daemon-side plugin handler.
openSurface(id) All Opens one of this plugin's registered global surfaces.
workspace Workspace and agent Synchronous workspace snapshot.
agent Agent Synchronous matching agent snapshot.
openPanel(id, options?) Workspace and agent Opens a registered panel in the callback's current context. Pass { location: "explorer" } to target Explorer.

An agent callback may open either an agent panel or a workspace panel. A workspace callback may open only a workspace panel. Unknown surface and panel IDs fail visibly. Use paseo for normal workspace, agent, provider, and daemon-config operations. Use rpc for plugin-specific filesystem, credential, vendor, or daemon-local work.

Slash commands

Register a command that runs in the Paseo client when the user submits /name args from the message composer. The text is never sent to the agent:

client.addSlashCommand({
  name: "review",
  description: "Run the review bot",
  argumentHint: "[scope]",
  context: "agent",
  async onSubmit({ args, agent, rpc, openPanel }) {
    await rpc(refreshReview, { agentId: agent.id, scope: args });
    openPanel("review");
  },
});
Field Required Meaning
name Yes Command name without the leading slash.
description Yes Composer autocomplete description.
argumentHint Yes Short usage hint shown after the command name.
context Yes "workspace" or "agent".
onSubmit Yes Client callback for the matching context.

onSubmit receives the matching Command Center callback context plus args. For /review src, args is "src"; Paseo trims only the remainder's leading and trailing whitespace and leaves parsing to the plugin. Paseo owns the autocomplete row, input clearing, and the error toast. It does not wait for onSubmit or show a pending state; use a composer pill or panel for that.

Precedence is built-in client commands, plugin commands, then provider commands. A lower-precedence collision is omitted. Built-in aliases also reserve their names. The first plugin in stable catalog order wins a collision between plugins. Commands do not run while the composer has attachments.

Composer pills

The client entry owns pill creation and removal. This can live directly in index.client.tsx or in a function it imports from client/:

import { Icon } from "@getpaseo/plugin/client/react-native";
import {
  type PluginClientContext,
  type PluginComposerPillProps,
  useAgent,
} from "@getpaseo/plugin/client";
import { Text } from "react-native";

function ReviewPill({ theme, agentId }: PluginComposerPillProps) {
  const agent = useAgent(agentId, ({ title }) => ({ title }));
  return (
    <>
      <Icon name="Scan" size={14} color={theme.colors.foregroundMuted} />
      <Text numberOfLines={1} style={{ color: theme.colors.foregroundMuted, flexShrink: 1 }}>
        {agent?.title ?? "Review"}
      </Text>
    </>
  );
}

export default function contribute(client: PluginClientContext) {
  const pills = new Map<string, () => void>();
  const unsubscribe = client.paseo.agents.subscribe((update) => {
    if (update.kind !== "upsert" || !update.agent.workspaceId) return;
    const { id: agentId, workspaceId } = update.agent;
    pills.get(agentId)?.();
    pills.set(
      agentId,
      client.addComposerPill({
        id: "review",
        title: "Open review",
        workspaceId,
        agentId,
        Component: ReviewPill,
        async onPress() {
          await client.rpc(refreshReview, { agentId });
          client.openPanel("review", { workspaceId, agentId });
        },
      }),
    );
  });
  return () => {
    unsubscribe();
    for (const remove of pills.values()) remove();
  };
}

addComposerPill fields:

Field Required Meaning
id Yes Plugin-local ID within the target agent.
title Yes Accessible button label.
workspaceId Yes Workspace whose composer track owns the pill.
agentId Yes Agent whose composer track owns the pill.
Component Yes React Native component rendering the pill's icon and text.
onPress Yes Client-side callback.

The client entry runs once per plugin installation in each connected app. Its context exposes paseo, typed rpc, openSurface, explicit-context openPanel, and every client registration. addComposerPill returns an idempotent removal function. Paseo also removes every outstanding pill when the plugin installation or host connection is torn down.

Paseo owns the pressable, shared pill chrome, pending state, error reporting, and track-bar placement. The component receives theme, host, layout, workspaceId, and agentId. Read current values with useWorkspace and useAgent. The plugin owns when the pill exists, its icon and text, and the callback. openPanel(id, { workspaceId, agentId? }) opens or focuses a panel registered by the same plugin.

Use the Paseo SDK

Use usePaseo() for ordinary Paseo operations from a surface. It borrows the selected host's existing connection; do not create another client.

import { type PluginSurfaceProps, usePaseo } from "@getpaseo/plugin/client";
import { Pressable, Text } from "react-native";

function PullRequestAction({ theme }: PluginSurfaceProps) {
  const paseo = usePaseo();

  async function createReviewWorkspace() {
    const workspace = await paseo.workspaces.create({
      title: "Review PR 42",
      source: {
        kind: "worktree",
        cwd: "/absolute/path/to/repository",
        action: "checkout",
        checkoutSource: { kind: "change_request", forge: "github", number: 42 },
      },
    });
    await workspace.agents.create({
      config: { provider: "codex/gpt-5.5" },
      prompt: "Review PR #42.",
    });
  }

  return (
    <Pressable accessibilityRole="button" onPress={() => void createReviewWorkspace()}>
      <Text style={{ color: theme.colors.foreground }}>Create review workspace</Text>
    </Pressable>
  );
}

The returned API covers projects, workspaces, agents, terminals, providers, and daemon config. See the SDK API reference for its methods. Connection lifecycle methods are intentionally absent because Paseo owns the connection.

Add plugin-specific backend behavior

Use plugin RPC only for work that is not a normal Paseo operation: reading a vendor API, accessing daemon-local resources, or keeping credentials off the client.

Define one contract with Zod, handle it in the subprocess, and call it from the surface:

shared/greeting.ts:

import { defineRpc } from "@getpaseo/plugin";
import { z } from "zod";

export const greeting = defineRpc({
  name: "greeting.create",
  input: z.object({ name: z.string() }),
  output: z.object({ message: z.string() }),
});

client/greeting.tsx:

import { useRpc } from "@getpaseo/plugin/client";
import { greeting } from "../shared/greeting";

export function GreetingButton() {
  const createGreeting = useRpc(greeting);
  // Call createGreeting({ name: "Ada" }) from an event or query.
  return null;
}

server/greeting.ts:

import type { RpcInput } from "@getpaseo/plugin";
import { greeting } from "../shared/greeting";

export function createGreeting({ name }: RpcInput<typeof greeting>) {
  return { message: `Hello, ${name}` };
}

index.client.tsx:

import type { PluginClientContext } from "@getpaseo/plugin/client";
import { GreetingButton } from "./client/greeting";

export default function contribute(client: PluginClientContext) {
  client.addSurface("main", GreetingButton);
  return () => {};
}

index.server.ts:

import type { PluginServerContext } from "@getpaseo/plugin/server";
import { createGreeting } from "./server/greeting";
import { greeting } from "./shared/greeting";

export default function contribute(server: PluginServerContext) {
  server.handle(greeting, createGreeting);
  return () => {};
}

Inputs and outputs are validated on both sides. RPC names start with a lowercase letter and contain lowercase letters, numbers, dots, hyphens, or underscores. useRpc() returns a typed async function. Use TanStack Query for request state, caching, and mutations.

Backend handlers receive the same PaseoApi as { paseo }. Their connection belongs to the subprocess and closes when the plugin stops. Backend code can use Node APIs and dependencies installed in the plugin directory.

Debug backend output

Backend contributions can write to stdout and stderr with normal Node logging:

console.log("Refreshing issues");
console.error("Issue refresh failed", error);

Paseo adds [paseo] entries when the plugin starts loading, becomes ready, starts stopping, and has stopped. It records compilation and load failures as stderr entries, including failures that happen before the plugin subprocess starts. Paseo also captures output emitted during initialization, RPC handlers, cleanup, and process failure. Protocol traffic uses a separate channel, so console.log() cannot corrupt plugin RPCs.

Open Settings → Plugins → Logs for the plugin, or inspect the same recent tail from the daemon CLI:

paseo plugin logs my-plugin
paseo plugin logs my-plugin --json
paseo --host <url> plugin logs my-plugin

The command returns a snapshot rather than following live output. Refresh the settings view or run the command again for newer entries. Each entry includes its timestamp, stdout or stderr stream, sequence, and message.

Paseo retains up to 500 entries and 256 KiB per plugin in memory. Individual lines are capped at 16 KiB. Reload, disable, compilation failure, initialization failure, and process failure retain the tail. Removing the plugin clears it, and a daemon restart starts a new tail. Structured copies are also written to the daemon log at $PASEO_HOME/daemon.log.

Only daemon-side output is captured. Logs from client surfaces remain in the app runtime. Do not log credentials, access tokens, or other secrets: connected users can read the retained tail, and the daemon log persists it.

Add a composer attachment source

An attachment source searches external resources and returns a stable text snapshot for an agent prompt. Keep credentials and vendor calls in the backend handler.

shared/issues.ts:

import { defineAttachmentSource, defineRpc } from "@getpaseo/plugin";
import { z } from "zod";

export const searchIssues = defineRpc({
  name: "issues.search",
  input: z.object({ query: z.string() }),
  output: z.object({
    items: z.array(
      z.object({
        id: z.string(),
        identifier: z.string(),
        title: z.string(),
        subtitle: z.string().optional(),
        url: z.string().url(),
        text: z.string(),
        resourceType: z.string(),
      }),
    ),
  }),
});

export const issues = defineAttachmentSource({
  id: "issues",
  title: "Acme issue",
  icon: "CircleDot",
  pickerTitle: "Attach Acme issue",
  searchPlaceholder: "Search by identifier or title",
  search: searchIssues,
});

server/issues.ts:

import type { RpcInput } from "@getpaseo/plugin";
import { searchIssues } from "../shared/issues";

export function search({ query }: RpcInput<typeof searchIssues>) {
  return searchAcmeIssues(query);
}

index.client.tsx:

import type { PluginClientContext } from "@getpaseo/plugin/client";
import { issues } from "./shared/issues";

export default function contribute(client: PluginClientContext) {
  client.addAttachmentSource(issues);
  return () => {};
}

index.server.ts:

import type { PluginServerContext } from "@getpaseo/plugin/server";
import { search } from "./server/issues";
import { searchIssues } from "./shared/issues";

export default function contribute(server: PluginServerContext) {
  server.handle(searchIssues, search);
  return () => {};
}

Paseo owns the composer menu, search picker, selected pill, draft state, and submission. The text value is the complete snapshot sent to the agent.

Hosts and lifecycle

Plugins are installed per daemon. When the same contribution exists on several connected hosts, Paseo shows one sidebar item and adds a host picker. The selected host supplies the bundle, Paseo API, RPC transport, and query cache. Calls never fall through to another host when the selected host is offline.

Attachment sources remain scoped to each composer's host.

Workspace panels and Command Center items stay scoped to the active host and exact cached context. Reload replaces their registrations. Disable, removal, host disconnect, and evaluation failure remove Command Center items and clear the installation's query state. An already-restored panel tab remains as unavailable until its matching contribution returns or the user closes it. Panel render failures stay inside the plugin error boundary.

ls reports runtime state, source details, and the installed commit without contacting the remote. Use update when you want Paseo to contact a tracked Git remote and install an available update.

Put --host <url> before a management command when the target is not the CLI's default daemon. remove never deletes a directory source; it deletes the managed checkout for a Git source. The install-time --id is the runtime ID and allows the same directory or repository to be installed more than once.

Trust every plugin you add. paseo plugin add and paseo plugin install mean “I trust this codebase.” Server code and Git preparation commands run unsandboxed with the daemon user's access on the daemon host; client contributions run inside Paseo. Dependencies and future updates are part of that decision. With the global --host option, commands run on the remote daemon host.

An existing directory wins over owner/repository GitHub shorthand. Append :relative/path when the plugin lives below the repository root. Omit --ref to track the default branch. Explicit branches track updates; tags and commits stay pinned.

Most plugins should omit build. Use it only when the staged checkout must install a dependency that Paseo does not provide, generate source or assets, or perform another required preparation step:

{
  "id": "review",
  "requirements": { "paseo": ">=0.8.0" },
  "build": [
    ["npm", "ci"],
    ["npm", "run", "build"]
  ]
}

build is a list of non-empty argv arrays. Paseo runs each executable directly, without a shell, from the staged plugin directory after resolving the exact commit and manifest. It never infers a package manager or commands from lockfiles. Install and update both run build before validation, compilation, activation, or replacement. A failing command reports its output, discards the candidate, and leaves the installed/running version intact. The daemon log records each command and output; with the global --host option, execution is on that daemon host.

Run npm run typecheck before install or reload. Manage plugin source entries with the CLI or Settings.

The daemon-wide Enable plugins switch lives under Settings → Plugins. A configured plugin remains disabled until that switch and the plugin's own enabled state are both on.

The switch is the root pluginsEnabled field in config.json. After changing it, run paseo reload --json. Enabling starts every configured plugin whose own enabled value is not false; disabling tears down all plugins. No daemon restart is required. Manual edits to plugin source entries are not reloaded; use the plugin lifecycle commands for those.

Load failures

Use paseo plugin ls to read the current status and error.

Symptom Check
This plugin was made for an older version of Paseo The directory has only an index.ts entry. Follow the migration guide.
Plugin entry points are missing Neither index.client.tsx nor index.server.ts exists with that exact name.
server-only module cannot be imported into the plugin client bundle Client code imports server/. Move the work behind an RPC and import its contract from shared/.
client-only module cannot be imported into the plugin server bundle Server code imports client/. Register that contribution from index.client.tsx instead.
Node module cannot be imported into the plugin client bundle Client code imports node:*. Move the operation to server/ and call it through an RPC.
Sidebar item is missing The plugin is running, the item references an existing surface, the icon name is valid, and the client is on the installation's host.
Client module is unavailable Import only the host-provided client modules listed above.
RPC rejects Check both Zod schemas and the daemon-side handler error.
Edited code does not appear Run npm run typecheck, then paseo plugin reload <id>.
Reload fails Read paseo plugin ls and paseo plugin logs <id>, fix the source error, then reload; Paseo does not restore the previous bundle.
Plugin exits unexpectedly Read paseo plugin logs <id> for retained initialization, cleanup, stderr, and final crash output.
