# Kitchen Sink Plugin Plan
## Goal
Add a new first-party example plugin, `Kitchen Sink (Example)`, that demonstrates every currently implemented Paperclip plugin API surface in one place.
This plugin is meant to be:
- a living reference implementation for contributors
- a manual test harness for the plugin runtime
- a discoverable demo of what plugins can actually do today
It is not meant to be a polished end-user product plugin.
## Why
The current plugin system has a real API surface, but it is spread across:
- SDK docs
- SDK types
- plugin spec prose
- two example plugins that each show only a narrow slice
That makes it hard to answer basic questions like:
- what can plugins render?
- what can plugin workers actually do?
- which surfaces are real versus aspirational?
- how should a new plugin be structured in this repo?
The kitchen-sink plugin should answer those questions by example.
## Success Criteria
The plugin is successful if a contributor can install it and, without reading the SDK first, discover and exercise the current plugin runtime surface area from inside Paperclip.
Concretely:
- it installs from the bundled examples list
- it exposes at least one demo for every implemented worker API surface
- it exposes at least one demo for every host-mounted UI surface
- it clearly labels local-only / trusted-only demos
- it is safe enough for local development by default
- it doubles as a regression harness for plugin runtime changes
## Constraints
- Keep it instance-installed, not company-installed.
- Treat this as a trusted/local example plugin.
- Do not rely on cloud-safe runtime assumptions.
- Avoid destructive defaults.
- Avoid irreversible mutations unless they are clearly labeled and easy to undo.
## Source Of Truth For This Plan
This plan is based on the currently implemented SDK/types/runtime, not only the long-horizon spec.
Primary references:
- `packages/plugins/sdk/README.md`
- `packages/plugins/sdk/src/types.ts`
- `packages/plugins/sdk/src/ui/types.ts`
- `packages/shared/src/constants.ts`
- `packages/shared/src/types/plugin.ts`
## Current Surface Inventory
### Worker/runtime APIs to demonstrate
These are the concrete `ctx` clients currently exposed by the SDK:
- `ctx.config`
- `ctx.events`
- `ctx.jobs`
- `ctx.launchers`
- `ctx.http`
- `ctx.secrets`
- `ctx.assets`
- `ctx.activity`
- `ctx.state`
- `ctx.entities`
- `ctx.projects`
- `ctx.companies`
- `ctx.issues`
- `ctx.agents`
- `ctx.goals`
- `ctx.data`
- `ctx.actions`
- `ctx.streams`
- `ctx.tools`
- `ctx.metrics`
- `ctx.logger`
### UI surfaces to demonstrate
Surfaces defined in the SDK:
- `page`
- `settingsPage`
- `dashboardWidget`
- `sidebar`
- `sidebarPanel`
- `detailTab`
- `taskDetailView`
- `projectSidebarItem`
- `toolbarButton`
- `contextMenuItem`
- `commentAnnotation`
- `commentContextMenuItem`
### Current host confidence
Confirmed or strongly indicated as mounted in the current app:
- `page`
- `settingsPage`
- `dashboardWidget`
- `detailTab`
- `projectSidebarItem`
- comment surfaces
- launcher infrastructure
Need explicit validation before claiming full demo coverage:
- `sidebar`
- `sidebarPanel`
- `taskDetailView`
- `toolbarButton` as direct slot, distinct from launcher placement
- `contextMenuItem` as direct slot, distinct from comment menu and launcher placement
The implementation should keep a small validation checklist for these before we call the plugin "complete".
## Plugin Concept
The plugin should be named:
- display name: `Kitchen Sink (Example)`
- package: `@paperclipai/plugin-kitchen-sink-example`
- plugin id: `paperclip.kitchen-sink-example` or `paperclip-kitchen-sink-example`
Recommendation: use `paperclip-kitchen-sink-example` to match current in-repo example naming style.
Category mix:
- `ui`
- `automation`
- `workspace`
- `connector`
That is intentionally broad because the point is coverage.
## UX Shape
The plugin should have one main full-page demo console plus smaller satellites on other surfaces.
### 1. Plugin page
Primary route: the plugin `page` surface should be the central dashboard for all demos.
Recommended page sections:
- `Overview`
- what this plugin demonstrates
- current capabilities granted
- current host context
- `UI Surfaces`
- links explaining where each other surface should appear
- `Data + Actions`
- buttons and forms for bridge-driven worker demos
- `Events + Streams`
- emit event
- watch event log
- stream demo output
- `Paperclip Domain APIs`
- companies
- projects/workspaces
- issues
- goals
- agents
- `Local Workspace + Process`
- file listing
- file read/write scratch area
- child process demo
- `Jobs + Webhooks + Tools`
- job status
- webhook URL and recent deliveries
- declared tools
- `State + Entities + Assets`
- scoped state editor
- plugin entity inspector
- upload/generated asset demo
- `Observability`
- metrics written
- activity log samples
- latest worker logs
### 2. Dashboard widget
A compact widget on the main dashboard should show:
- plugin health
- count of demos exercised
- recent event/stream activity
- shortcut to the full plugin page
### 3. Project sidebar item
Add a `Kitchen Sink` link under each project that deep-links into a project-scoped plugin tab.
### 4. Detail tabs
Use detail tabs to demonstrate entity-context rendering on:
- `project`
- `issue`
- `agent`
- `goal`
Each tab should show:
- the host context it received
- the relevant entity fetch via worker bridge
- one small action scoped to that entity
### 5. Comment surfaces
Use issue comment demos to prove comment-specific extension points:
- `commentAnnotation`
- render parsed metadata below each comment
- show comment id, issue id, and a small derived status
- `commentContextMenuItem`
- add a menu action like `Copy Context To Kitchen Sink`
- action writes a plugin entity or state record for later inspection
### 6. Settings page
Custom `settingsPage` should be intentionally simple and operational:
- `About`
- `Danger / Trust Model`
- demo toggles
- local process defaults
- workspace scratch-path behavior
- secret reference inputs
- event/job/webhook sample config
This plugin should also keep the generic plugin settings `Status` tab useful by writing health, logs, and metrics.
## Feature Matrix
Each implemented worker API should have a visible demo.
### `ctx.config`
Demo:
- read live config
- show config JSON
- react to config changes without restart where possible
### `ctx.events`
Demos:
- emit a plugin event
- subscribe to plugin events
- subscribe to a core Paperclip event such as `issue.created`
- show recent received events in a timeline
### `ctx.jobs`
Demos:
- one scheduled heartbeat-style demo job
- one manual run button from the UI if host supports manual job trigger
- show last run result and timestamps
### `ctx.launchers`
Demos:
- declare launchers in manifest
- optionally register one runtime launcher from the worker
- show launcher metadata on the plugin page
### `ctx.http`
Demo:
- make a simple outbound GET request to a safe endpoint
- show status code, latency, and JSON result
Recommendation: default to a Paperclip-local endpoint or a stable public echo endpoint to avoid flaky docs.
### `ctx.secrets`
Demo:
- operator enters a secret reference in config
- plugin resolves it on demand
- UI only shows masked result length / success status, never raw secret
### `ctx.assets`
Demos:
- generate a text asset from the UI
- optionally upload a tiny JSON blob or screenshot-like text file
- show returned asset URL
### `ctx.activity`
Demo:
- button to write a plugin activity log entry against current company/entity
### `ctx.state`
Demos:
- instance-scoped state
- company-scoped state
- project-scoped state
- issue-scoped state
- delete/reset controls
Use a small state inspector/editor on the plugin page.
### `ctx.entities`
Demos:
- create plugin-owned sample records
- list/filter them
- show one realistic use case such as "copied comments" or "demo sync records"
### `ctx.projects`
Demos:
- list projects
- list project workspaces
- resolve primary workspace
- resolve workspace for issue
### `ctx.companies`
Demo:
- list companies and show current selected company
### `ctx.issues`
Demos:
- list issues in current company
- create issue
- update issue status/title
- list comments
- create comment
### `ctx.agents`
Demos:
- list agents
- invoke one agent with a test prompt
- pause/resume where safe
Agent mutation controls should be behind an explicit warning.
### `ctx.agents.sessions`
Demos:
- create agent chat session
- send message
- stream events back to the UI
- close session
This is a strong candidate for the best "wow" demo on the plugin page.
### `ctx.goals`
Demos:
- list goals
- create goal
- update status/title
### `ctx.data`
Use throughout the plugin for all read-side bridge demos.
### `ctx.actions`
Use throughout the plugin for all mutation-side bridge demos.
### `ctx.streams`
Demos:
- live event log stream
- token-style stream from an agent session relay
- fake progress stream for a long-running action
### `ctx.tools`
Demos:
- declare 2-3 simple agent tools
- tool 1: echo/diagnostics
- tool 2: project/workspace summary
- tool 3: create issue or write plugin state
The plugin page should list declared tools and show example input payloads.
### `ctx.metrics`
Demo:
- write a sample metric on each major demo action
- surface a small recent metrics table in the plugin page
### `ctx.logger`
Demo:
- every action logs structured entries
- plugin settings `Status` page then doubles as the log viewer
## Local Workspace And Process Demos
The plugin SDK intentionally leaves file/process operations to the plugin itself once it has workspace metadata.
The kitchen-sink plugin should demonstrate that explicitly.
### Workspace demos
- list files from a selected workspace
- read a file
- write to a plugin-owned scratch file
- optionally search files with `rg` if available
### Process demos
- run a short-lived command like `pwd`, `ls`, or `git status`
- stream stdout/stderr back to UI
- show exit code and timing
Important safeguards:
- default commands must be read-only
- no shell interpolation from arbitrary free-form input in v1
- provide a curated command list or a strongly validated command form
- clearly label this area as local-only and trusted-only
## Proposed Manifest Coverage
The plugin should aim to declare:
- `page`
- `settingsPage`
- `dashboardWidget`
- `detailTab` for `project`, `issue`, `agent`, `goal`
- `projectSidebarItem`
- `commentAnnotation`
- `commentContextMenuItem`
Then, after host validation, add if supported:
- `sidebar`
- `sidebarPanel`
- `taskDetailView`
- `toolbarButton`
- `contextMenuItem`
It should also declare one or more `ui.launchers` entries to exercise launcher behavior independently of slot rendering.
## Proposed Package Layout
New package:
- `packages/plugins/examples/plugin-kitchen-sink-example/`
Expected files:
- `package.json`
- `README.md`
- `tsconfig.json`
- `src/index.ts`
- `src/manifest.ts`
- `src/worker.ts`
- `src/ui/index.tsx`
- `src/ui/components/...`
- `src/ui/hooks/...`
- `src/lib/...`
- optional `scripts/build-ui.mjs` if UI bundling needs esbuild
## Proposed Internal Architecture
### Worker modules
Recommended split:
- `src/worker.ts`
- plugin definition and wiring
- `src/worker/data.ts`
- `ctx.data.register(...)`
- `src/worker/actions.ts`
- `ctx.actions.register(...)`
- `src/worker/events.ts`
- event subscriptions and event log buffer
- `src/worker/jobs.ts`
- scheduled job handlers
- `src/worker/tools.ts`
- tool declarations and handlers
- `src/worker/local-runtime.ts`
- file/process demos
- `src/worker/demo-store.ts`
- helpers for state/entities/assets/metrics
### UI modules
Recommended split:
- `src/ui/index.tsx`
- exported slot components
- `src/ui/page/KitchenSinkPage.tsx`
- `src/ui/settings/KitchenSinkSettingsPage.tsx`
- `src/ui/widgets/KitchenSinkDashboardWidget.tsx`
- `src/ui/tabs/ProjectKitchenSinkTab.tsx`
- `src/ui/tabs/IssueKitchenSinkTab.tsx`
- `src/ui/tabs/AgentKitchenSinkTab.tsx`
- `src/ui/tabs/GoalKitchenSinkTab.tsx`
- `src/ui/comments/KitchenSinkCommentAnnotation.tsx`
- `src/ui/comments/KitchenSinkCommentMenuItem.tsx`
- `src/ui/shared/...`
## Configuration Schema
The plugin should have a substantial but understandable `instanceConfigSchema`.
Recommended config fields:
- `enableDangerousDemos`
- `enableWorkspaceDemos`
- `enableProcessDemos`
- `showSidebarEntry`
- `showSidebarPanel`
- `showProjectSidebarItem`
- `showCommentAnnotation`
- `showCommentContextMenuItem`
- `showToolbarLauncher`
- `defaultDemoCompanyId` optional
- `secretRefExample`
- `httpDemoUrl`
- `processAllowedCommands`
- `workspaceScratchSubdir`
Defaults should keep risky behavior off.
## Safety Defaults
Default posture:
- UI and read-only demos on
- mutating domain demos on but explicitly labeled
- process demos off by default
- no arbitrary shell input by default
- no raw secret rendering ever
## Phased Build Plan
### Phase 1: Core plugin skeleton
- scaffold package
- add manifest, worker, UI entrypoints
- add README
- make it appear in bundled examples list
### Phase 2: Core, confirmed UI surfaces
- plugin page
- settings page
- dashboard widget
- project sidebar item
- detail tabs
### Phase 3: Core worker APIs
- config
- state
- entities
- companies/projects/issues/goals
- data/actions
- metrics/logger/activity
### Phase 4: Real-time and automation APIs
- streams
- events
- jobs
- webhooks
- agent sessions
- tools
### Phase 5: Local trusted runtime demos
- workspace file demos
- child process demos
- guarded by config
### Phase 6: Secondary UI surfaces
- comment annotation
- comment context menu item
- launchers
### Phase 7: Validation-only surfaces
Validate whether the current host truly mounts:
- `sidebar`
- `sidebarPanel`
- `taskDetailView`
- direct-slot `toolbarButton`
- direct-slot `contextMenuItem`
If mounted, add demos.
If not mounted, document them as SDK-defined but host-pending.
## Documentation Deliverables
The plugin should ship with a README that includes:
- what it demonstrates
- which surfaces are local-only
- how to install it
- where each UI surface should appear
- a mapping from demo card to SDK API
It should also be referenced from plugin docs as the "reference everything plugin".
## Testing And Verification
Minimum verification:
- package typecheck/build
- install from bundled example list
- page loads
- widget appears
- project tab appears
- comment surfaces render
- settings page loads
- key actions succeed
Recommended manual checklist:
- create issue from plugin
- create goal from plugin
- emit and receive plugin event
- stream action output
- open agent session and receive streamed reply
- upload an asset
- write plugin activity log
- run a safe local process demo
## Open Questions
1. Should the process demo remain curated-command-only in the first pass?
Recommendation: yes.
2. Should the plugin create throwaway "kitchen sink demo" issues/goals automatically?
Recommendation: no. Make creation explicit.
3. Should we expose unsupported-but-typed surfaces in the UI even if host mounting is not wired?
Recommendation: yes, but label them as `SDK-defined / host validation pending`.
4. Should agent mutation demos include pause/resume by default?
Recommendation: probably yes, but behind a warning block.
5. Should this plugin be treated as a supported regression harness in CI later?
Recommendation: yes. Long term, this should be the plugin-runtime smoke test package.
## Recommended Next Step
If this plan looks right, the next implementation pass should start by building only:
- package skeleton
- page
- settings page
- dashboard widget
- one project detail tab
- one issue detail tab
- the basic worker/action/data/state/event scaffolding
That is enough to lock the architecture before filling in every demo surface.

# Plugin Authoring Guide
This guide describes the current, implemented way to create a Paperclip plugin in this repo.
It is intentionally narrower than [PLUGIN_SPEC.md](./PLUGIN_SPEC.md). The spec includes future ideas; this guide only covers the alpha surface that exists now.
## Current reality
- Treat plugin workers and plugin UI as trusted code.
- Plugin UI runs as same-origin JavaScript inside the main Paperclip app.
- Worker-side host APIs are capability-gated.
- Plugin UI is not sandboxed by manifest capabilities.
- There is no host-provided shared React component kit for plugins yet.
- `ctx.assets` is not supported in the current runtime.
## Scaffold a plugin
Use the scaffold package:
```bash
pnpm --filter @paperclipai/create-paperclip-plugin build
node packages/plugins/create-paperclip-plugin/dist/index.js @yourscope/plugin-name --output ./packages/plugins/examples
```
For a plugin that lives outside the Paperclip repo:
```bash
pnpm --filter @paperclipai/create-paperclip-plugin build
node packages/plugins/create-paperclip-plugin/dist/index.js @yourscope/plugin-name \
--output /absolute/path/to/plugin-repos \
--sdk-path /absolute/path/to/paperclip/packages/plugins/sdk
```
That creates a package with:
- `src/manifest.ts`
- `src/worker.ts`
- `src/ui/index.tsx`
- `tests/plugin.spec.ts`
- `esbuild.config.mjs`
- `rollup.config.mjs`
Inside this monorepo, the scaffold uses `workspace:*` for `@paperclipai/plugin-sdk`.
Outside this monorepo, the scaffold snapshots `@paperclipai/plugin-sdk` from the local Paperclip checkout into a `.paperclip-sdk/` tarball so you can build and test a plugin without publishing anything to npm first.
## Recommended local workflow
From the generated plugin folder:
```bash
pnpm install
pnpm typecheck
pnpm test
pnpm build
```
For local development, install it into Paperclip from an absolute local path through the plugin manager or API. The server supports local filesystem installs and watches local-path plugins for file changes so worker restarts happen automatically after rebuilds.
Example:
```bash
curl -X POST http://127.0.0.1:3100/api/plugins/install \
-H "Content-Type: application/json" \
-d '{"packageName":"/absolute/path/to/your-plugin","isLocalPath":true}'
```
## Supported alpha surface
Worker:
- config
- events
- jobs
- launchers
- http
- secrets
- activity
- state
- entities
- projects and project workspaces
- companies
- issues and comments
- agents and agent sessions
- goals
- data/actions
- streams
- tools
- metrics
- logger
UI:
- `usePluginData`
- `usePluginAction`
- `usePluginStream`
- `usePluginToast`
- `useHostContext`
- typed slot props from `@paperclipai/plugin-sdk/ui`
Mount surfaces currently wired in the host include:
- `page`
- `settingsPage`
- `dashboardWidget`
- `sidebar`
- `sidebarPanel`
- `detailTab`
- `taskDetailView`
- `projectSidebarItem`
- `toolbarButton`
- `contextMenuItem`
- `commentAnnotation`
- `commentContextMenuItem`
## Company routes
Plugins may declare a `page` slot with `routePath` to own a company route like:
```text
/:companyPrefix/<routePath>
```
Rules:
- `routePath` must be a single lowercase slug
- it cannot collide with reserved host routes
- it cannot duplicate another installed plugin page route
## Publishing guidance
- Use npm packages as the deployment artifact.
- Treat repo-local example installs as a development workflow only.
- Prefer keeping plugin UI self-contained inside the package.
- Do not rely on host design-system components or undocumented app internals.
- GitHub repository installs are not a first-class workflow today. For local development, use a checked-out local path. For production, publish to npm or a private npm-compatible registry.
## Verification before handoff
At minimum:
```bash
pnpm --filter <your-plugin-package> typecheck
pnpm --filter <your-plugin-package> test
pnpm --filter <your-plugin-package> build
```
If you changed host integration too, also run:
```bash
pnpm -r typecheck
pnpm test:run
pnpm build
```

This is not part of the V1 implementation contract in [doc/SPEC-implementation.md](../SPEC-implementation.md).
It is the full target architecture for the plugin system that should follow V1.
## Current implementation caveats
The code in this repo now includes an early plugin runtime and admin UI, but it does not yet deliver the full deployment model described in this spec.
Today, the practical deployment model is:
- single-tenant
- self-hosted
- single-node or otherwise filesystem-persistent
Current limitations to keep in mind:
- Plugin UI bundles currently run as same-origin JavaScript inside the main Paperclip app. Treat plugin UI as trusted code, not a sandboxed frontend capability boundary.
- Manifest capabilities currently gate worker-side host RPC calls. They do not prevent plugin UI code from calling ordinary Paperclip HTTP APIs directly.
- Runtime installs assume a writable local filesystem for the plugin package directory and plugin data directory.
- Runtime npm installs assume `npm` is available in the running environment and that the host can reach the configured package registry.
- Published npm packages are the intended install artifact for deployed plugins.
- The repo example plugins under `packages/plugins/examples/` are development conveniences. They work from a source checkout and should not be assumed to exist in a generic published build unless they are explicitly shipped with that build.
- Dynamic plugin install is not yet cloud-ready for horizontally scaled or ephemeral deployments. There is no shared artifact store, install coordination, or cross-node distribution layer yet.
- The current runtime does not yet ship a real host-provided plugin UI component kit, and it does not support plugin asset uploads/reads. Treat those as future-scope ideas in this spec, not current implementation promises.
In practice, that means the current implementation is a good fit for local development and self-hosted persistent deployments, but not yet for multi-instance cloud plugin distribution.

* creates a row in this table before dispatching the payload to the plugin
* worker. This provides an auditable log of every delivery attempt.
*
* The `webhook_key` matches the key declared in the plugin manifest's
* `webhooks` array. `external_id` is an optional identifier supplied by the
* remote system (e.g. a GitHub delivery GUID) that can be used to detect
* and reject duplicate deliveries.
*
* Status values:
* - `pending` — received but not yet dispatched to the worker
* - `processing` — currently being handled by the plugin worker
* - `succeeded` — worker processed the payload successfully
* - `failed` — worker returned an error or timed out
*
* @see PLUGIN_SPEC.md §21.3 — `plugin_webhook_deliveries`

# @paperclipai/create-paperclip-plugin
Scaffolding tool for creating new Paperclip plugins.
```bash
npx @paperclipai/create-paperclip-plugin my-plugin
```
Or with options:
```bash
npx @paperclipai/create-paperclip-plugin @acme/my-plugin \
--template connector \
--category connector \
--display-name "Acme Connector" \
--description "Syncs Acme data into Paperclip" \
--author "Acme Inc"
```
Supported templates: `default`, `connector`, `workspace`
Supported categories: `connector`, `workspace`, `automation`, `ui`
Generates:
- typed manifest + worker entrypoint
- example UI widget using the supported `@paperclipai/plugin-sdk/ui` hooks
- test file using `@paperclipai/plugin-sdk/testing`
- `esbuild` and `rollup` config files using SDK bundler presets
- dev server script for hot-reload (`paperclip-plugin-dev-server`)
The scaffold intentionally uses plain React elements rather than host-provided UI kit components, because the current plugin runtime does not ship a stable shared component library yet.
Inside this repo, the generated package uses `@paperclipai/plugin-sdk` via `workspace:*`.
Outside this repo, the scaffold snapshots `@paperclipai/plugin-sdk` from your local Paperclip checkout into a `.paperclip-sdk/` tarball and points the generated package at that local file by default. You can override the SDK source explicitly:
```bash
node packages/plugins/create-paperclip-plugin/dist/index.js @acme/my-plugin \
--output /absolute/path/to/plugins \
--sdk-path /absolute/path/to/paperclip/packages/plugins/sdk
```
That gives you an outside-repo local development path before the SDK is published to npm.
## Workflow after scaffolding
```bash
cd my-plugin
pnpm install
pnpm dev # watch worker + manifest + ui bundles
pnpm dev:ui # local UI preview server with hot-reload events
pnpm test
```

# File Browser Example Plugin
Example Paperclip plugin that demonstrates:
- **projectSidebarItem** — An optional "Files" link under each project in the sidebar that opens the project detail with this plugins tab selected. This is controlled by plugin settings and defaults to off.
- **detailTab** (entityType project) — A project detail tab with a workspace-path selector, a desktop two-column layout (file tree left, editor right), and a mobile one-panel flow with a back button from editor to file tree, including save support.
This is a repo-local example plugin for development. It should not be assumed to ship in a generic production build unless it is explicitly included.
## Slots
| Slot | Type | Description |
|---------------------|---------------------|--------------------------------------------------|
| Files (sidebar) | `projectSidebarItem`| Optional link under each project → project detail + tab. |
| Files (tab) | `detailTab` | Responsive tree/editor layout with save support.|
## Settings
- `Show Files in Sidebar` — toggles the project sidebar link on or off. Defaults to off.
- `Comment File Links` — controls whether comment annotations and the comment context-menu action are shown.
## Capabilities
- `ui.sidebar.register` — project sidebar item
- `ui.detailTab.register` — project detail tab
- `projects.read` — resolve project
- `project.workspaces.read` — list workspaces and read paths for file access
## Worker
- **getData `workspaces`** — `ctx.projects.listWorkspaces(projectId, companyId)` (ordered, primary first).
- **getData `fileList`** — `{ projectId, workspaceId, directoryPath? }` → list directory entries for the workspace root or a subdirectory (Node `fs`).
- **getData `fileContent`** — `{ projectId, workspaceId, filePath }` → read file content using workspace-relative paths (Node `fs`).
- **performAction `writeFile`** — `{ projectId, workspaceId, filePath, content }` → write the current editor buffer back to disk.
## Local Install (Dev)
From the repo root, build the plugin and install it by local path:
```bash
pnpm --filter @paperclipai/plugin-file-browser-example build
pnpm paperclipai plugin install ./packages/plugins/examples/plugin-file-browser-example
```
To uninstall:
```bash
pnpm paperclipai plugin uninstall paperclip-file-browser-example --force
```
**Local development notes:**
- **Build first.** The host resolves the worker from the manifest `entrypoints.worker` (e.g. `./dist/worker.js`). Run `pnpm build` in the plugin directory before installing so the worker file exists.
- **Dev-only install path.** This local-path install flow assumes this monorepo checkout is present on disk. For deployed installs, publish an npm package instead of depending on `packages/plugins/examples/...` existing on the host.
- **Reinstall after pulling.** If you installed a plugin by local path before the server stored `package_path`, the plugin may show status **error** (worker not found). Uninstall and install again so the server persists the path and can activate the plugin.
- Optional: use `paperclip-plugin-dev-server` for UI hot-reload with `devUiUrl` in plugin config.
## Structure
- `src/manifest.ts` — manifest with `projectSidebarItem` and `detailTab` (entityTypes `["project"]`).
- `src/worker.ts` — data handlers for workspaces, file list, file content.
- `src/ui/index.tsx``FilesLink` (sidebar) and `FilesTab` (workspace path selector + two-panel file tree/editor).

# @paperclipai/plugin-hello-world-example
First-party reference plugin showing the smallest possible UI extension.
## What It Demonstrates
- a manifest with a `dashboardWidget` UI slot
- `entrypoints.ui` wiring for plugin UI bundles
- a minimal React widget rendered in the Paperclip dashboard
- reading host context (`companyId`) from `PluginWidgetProps`
- worker lifecycle hooks (`setup`, `onHealth`) for basic runtime observability
## API Surface
- This example does not add custom HTTP endpoints.
- The widget is discovered/rendered through host-managed plugin APIs (for example `GET /api/plugins/ui-contributions`).
## Notes
This is intentionally simple and is designed as the quickest "hello world" starting point for UI plugin authors.
It is a repo-local example plugin for development, not a plugin that should be assumed to ship in generic production builds.
## Local Install (Dev)
From the repo root, build the plugin and install it by local path:
```bash
pnpm --filter @paperclipai/plugin-hello-world-example build
pnpm paperclipai plugin install ./packages/plugins/examples/plugin-hello-world-example
```
**Local development notes:**
- **Build first.** The host resolves the worker from the manifest `entrypoints.worker` (e.g. `./dist/worker.js`). Run `pnpm build` in the plugin directory before installing so the worker file exists.
- **Dev-only install path.** This local-path install flow assumes a source checkout with this example package present on disk. For deployed installs, publish an npm package instead of relying on the monorepo example path.
- **Reinstall after pulling.** If you installed a plugin by local path before the server stored `package_path`, the plugin may show status **error** (worker not found). Uninstall and install again so the server persists the path and can activate the plugin:
`pnpm paperclipai plugin uninstall paperclip.hello-world-example --force` then
`pnpm paperclipai plugin install ./packages/plugins/examples/plugin-hello-world-example`.

# @paperclipai/plugin-kitchen-sink-example
Kitchen Sink is the first-party reference plugin that demonstrates nearly the full currently implemented Paperclip plugin surface in one package.
It is intentionally broad:
- full plugin page
- dashboard widget
- project and issue surfaces
- comment surfaces
- sidebar surfaces
- settings page
- worker bridge data/actions
- events, jobs, webhooks, tools, streams
- state, entities, assets, metrics, activity
- local workspace and process demos
This plugin is for local development, contributor onboarding, and runtime regression testing. It is not meant as a production plugin template to ship unchanged.
## Install
```sh
pnpm --filter @paperclipai/plugin-kitchen-sink-example build
pnpm paperclipai plugin install ./packages/plugins/examples/plugin-kitchen-sink-example
```
Or install it from the Paperclip plugin manager as a bundled example once this repo is built.
## Notes
- Local workspace and process demos are trusted-only and default to safe, curated commands.
- The plugin settings page lets you toggle optional demo surfaces and local runtime behavior.
- Some SDK-defined host surfaces still depend on the Paperclip host wiring them visibly; this package aims to exercise the currently mounted ones and make the rest obvious.

| `@paperclipai/plugin-sdk/protocol` | JSON-RPC protocol types and helpers (advanced) |
| `@paperclipai/plugin-sdk/types` | Worker context and API types (advanced) |
## Manifest entrypoints
In your plugin manifest you declare:
- **`entrypoints.worker`** (required) — Path to the worker bundle (e.g. `dist/worker.js`). The host loads this and calls `setup(ctx)`.
- **`entrypoints.ui`** (required if you use UI) — Path to the UI bundle directory. The host loads components from here for slots and launchers.
## Install
```bash
pnpm add @paperclipai/plugin-sdk
```
## Current deployment caveats
The SDK is stable enough for local development and first-party examples, but the runtime deployment model is still early.
- Plugin workers and plugin UI should both be treated as trusted code today.
- Plugin UI bundles run as same-origin JavaScript inside the main Paperclip app. They can call ordinary Paperclip HTTP APIs with the board session, so manifest capabilities are not a frontend sandbox.
- Local-path installs and the repo example plugins are development workflows. They assume the plugin source checkout exists on disk.
- For deployed plugins, publish an npm package and install that package into the Paperclip instance at runtime.
- The current host runtime expects a writable filesystem, `npm` available at runtime, and network access to the package registry used for plugin installation.
- Dynamic plugin install is currently best suited to single-node persistent deployments. Multi-instance cloud deployments still need a shared artifact/distribution model before runtime installs are reliable across nodes.
- The host does not currently ship a real shared React component kit for plugins. Build your plugin UI with ordinary React components and CSS.
- `ctx.assets` is not part of the supported runtime in this build. Do not depend on asset upload/read APIs yet.
If you are authoring a plugin for others to deploy, treat npm-packaged installation as the supported path and treat repo-local example installs as a development convenience.
## Worker quick start
```ts
import { definePlugin, runWorker } from "@paperclipai/plugin-sdk";
const plugin = definePlugin({
async setup(ctx) {
ctx.events.on("issue.created", async (event) => {
ctx.logger.info("Issue created", { issueId: event.entityId });
});
ctx.data.register("health", async () => ({ status: "ok" }));
ctx.actions.register("ping", async () => ({ pong: true }));
ctx.tools.register("calculator", {
displayName: "Calculator",
description: "Basic math",
parametersSchema: {
type: "object",
properties: { a: { type: "number" }, b: { type: "number" } },
required: ["a", "b"]
}
}, async (params) => {
const { a, b } = params as { a: number; b: number };
return { content: `Result: ${a + b}`, data: { result: a + b } };
});
},
});
export default plugin;
runWorker(plugin, import.meta.url);
```
**Note:** `runWorker(plugin, import.meta.url)` must be called so that when the host runs your worker (e.g. `node dist/worker.js`), the RPC host starts and the process stays alive. When the file is imported (e.g. for tests), the main-module check prevents the host from starting.
### Worker lifecycle and context
**Lifecycle (definePlugin):**
| Hook | Purpose |
|------|--------|
| `setup(ctx)` | **Required.** Called once at startup. Register event handlers, jobs, data/actions/tools, etc. |
| `onHealth?()` | Optional. Return `{ status, message?, details? }` for health dashboard. |
| `onConfigChanged?(newConfig)` | Optional. Apply new config without restart; if omitted, host restarts worker. |
| `onShutdown?()` | Optional. Clean up before process exit (limited time window). |
| `onValidateConfig?(config)` | Optional. Return `{ ok, warnings?, errors? }` for settings UI / Test Connection. |
| `onWebhook?(input)` | Optional. Handle `POST /api/plugins/:pluginId/webhooks/:endpointKey`; required if webhooks declared. |
**Context (`ctx`) in setup:** `config`, `events`, `jobs`, `launchers`, `http`, `secrets`, `activity`, `state`, `entities`, `projects`, `companies`, `issues`, `agents`, `goals`, `data`, `actions`, `streams`, `tools`, `metrics`, `logger`, `manifest`. Worker-side host APIs are capability-gated; declare capabilities in the manifest.
**Agents:** `ctx.agents.invoke(agentId, companyId, opts)` for one-shot invocation. `ctx.agents.sessions` for two-way chat: `create`, `list`, `sendMessage` (with streaming `onEvent` callback), `close`. See the [Plugin Authoring Guide](../../doc/plugins/PLUGIN_AUTHORING_GUIDE.md#agent-sessions-two-way-chat) for details.
**Jobs:** Declare in `manifest.jobs` with `jobKey`, `displayName`, `schedule` (cron). Register handler with `ctx.jobs.register(jobKey, fn)`. **Webhooks:** Declare in `manifest.webhooks` with `endpointKey`; handle in `onWebhook(input)`. **State:** `ctx.state.get/set/delete(scopeKey)`; scope kinds: `instance`, `company`, `project`, `project_workspace`, `agent`, `issue`, `goal`, `run`.
## Events
Subscribe in `setup` with `ctx.events.on(name, handler)` or `ctx.events.on(name, filter, handler)`. Emit plugin-scoped events with `ctx.events.emit(name, companyId, payload)` (requires `events.emit`).
**Core domain events (subscribe with `events.subscribe`):**
| Event | Typical entity |
|-------|-----------------|
| `company.created`, `company.updated` | company |
| `project.created`, `project.updated` | project |
| `project.workspace_created`, `project.workspace_updated`, `project.workspace_deleted` | project_workspace |
| `issue.created`, `issue.updated`, `issue.comment.created` | issue |
| `agent.created`, `agent.updated`, `agent.status_changed` | agent |
| `agent.run.started`, `agent.run.finished`, `agent.run.failed`, `agent.run.cancelled` | run |
| `goal.created`, `goal.updated` | goal |
| `approval.created`, `approval.decided` | approval |
| `cost_event.created` | cost |
| `activity.logged` | activity |
**Plugin-to-plugin:** Subscribe to `plugin.<pluginId>.<eventName>` (e.g. `plugin.acme.linear.sync-done`). Emit with `ctx.events.emit("sync-done", companyId, payload)`; the host namespaces it automatically.
**Filter (optional):** Pass a second argument to `on()`: `{ projectId?, companyId?, agentId? }` so the host only delivers matching events.
**Company context:** Events still carry `companyId` for company-scoped data, but plugin installation and activation are instance-wide in the current runtime.
## Scheduled (recurring) jobs
Plugins can declare **scheduled jobs** that the host runs on a cron schedule. Use this for recurring tasks like syncs, digest reports, or cleanup.
1. **Capability:** Add `jobs.schedule` to `manifest.capabilities`.
2. **Declare jobs** in `manifest.jobs`: each entry has `jobKey`, `displayName`, optional `description`, and `schedule` (a 5-field cron expression).
3. **Register a handler** in `setup()` with `ctx.jobs.register(jobKey, async (job) => { ... })`.
**Cron format** (5 fields: minute, hour, day-of-month, month, day-of-week):
| Field | Values | Example |
|-------------|----------|---------|
| minute | 059 | `0`, `*/15` |
| hour | 023 | `2`, `*` |
| day of month | 131 | `1`, `*` |
| month | 112 | `*` |
| day of week | 06 (Sun=0) | `*`, `1-5` |
Examples: `"0 * * * *"` = every hour at minute 0; `"*/5 * * * *"` = every 5 minutes; `"0 2 * * *"` = daily at 2:00.
**Job handler context** (`PluginJobContext`):
| Field | Type | Description |
|-------------|----------|-------------|
| `jobKey` | string | Matches the manifest declaration. |
| `runId` | string | UUID for this run. |
| `trigger` | `"schedule" \| "manual" \| "retry"` | What caused this run. |
| `scheduledAt` | string | ISO 8601 time when the run was scheduled. |
Runs can be triggered by the **schedule**, **manually** from the UI/API, or as a **retry** (when an operator re-runs a job after a failure). Re-throw from the handler to mark the run as failed; the host records the failure. The host does not automatically retry—operators can trigger another run manually from the UI or API.
Example:
**Manifest** — include `jobs.schedule` and declare the job:
```ts
// In your manifest (e.g. manifest.ts):
const manifest = {
// ...
capabilities: ["jobs.schedule", "plugin.state.write"],
jobs: [
{
jobKey: "heartbeat",
displayName: "Heartbeat",
description: "Runs every 5 minutes",
schedule: "*/5 * * * *",
},
],
// ...
};
```
**Worker** — register the handler in `setup()`:
```ts
ctx.jobs.register("heartbeat", async (job) => {
ctx.logger.info("Heartbeat run", { runId: job.runId, trigger: job.trigger });
await ctx.state.set({ scopeKind: "instance", stateKey: "last-heartbeat" }, new Date().toISOString());
});
```
## UI slots and launchers
Slots are mount points for plugin React components. Launchers are host-rendered entry points (buttons, menu items) that open plugin UI. Declare slots in `manifest.ui.slots` with `type`, `id`, `displayName`, `exportName`; for context-sensitive slots add `entityTypes`. Declare launchers in `manifest.ui.launchers` (or legacy `manifest.launchers`).
### Slot types / launcher placement zones
The same set of values is used as **slot types** (where a component mounts) and **launcher placement zones** (where a launcher can appear). Hierarchy:
| Slot type / placement zone | Scope | Entity types (when context-sensitive) |
|----------------------------|-------|---------------------------------------|
| `page` | Global | — |
| `sidebar` | Global | — |
| `sidebarPanel` | Global | — |
| `settingsPage` | Global | — |
| `dashboardWidget` | Global | — |
| `detailTab` | Entity | `project`, `issue`, `agent`, `goal`, `run` |
| `taskDetailView` | Entity | (task/issue context) |
| `commentAnnotation` | Entity | `comment` |
| `commentContextMenuItem` | Entity | `comment` |
| `projectSidebarItem` | Entity | `project` |
| `toolbarButton` | Entity | varies by host surface |
| `contextMenuItem` | Entity | varies by host surface |
**Scope** describes whether the slot requires an entity to render. **Global** slots render without a specific entity but still receive the active `companyId` through `PluginHostContext` — use it to scope data fetches to the current company. **Entity** slots additionally require `entityId` and `entityType` (e.g. a detail tab on a specific issue).
**Entity types** (for `entityTypes` on slots): `project` \| `issue` \| `agent` \| `goal` \| `run` \| `comment`. Full list: import `PLUGIN_UI_SLOT_TYPES` and `PLUGIN_UI_SLOT_ENTITY_TYPES` from `@paperclipai/plugin-sdk`.
### Slot component descriptions
#### `page`
A full-page extension mounted at `/plugins/:pluginId` (global) or `/:company/plugins/:pluginId` (company-context route). Use this for rich, standalone plugin experiences such as dashboards, configuration wizards, or multi-step workflows. Receives `PluginPageProps` with `context.companyId` set to the active company. Requires the `ui.page.register` capability.
#### `sidebar`
Adds a navigation-style entry to the main company sidebar navigation area, rendered alongside the core nav items (Dashboard, Issues, Goals, etc.). Use this for lightweight, always-visible links or status indicators that feel native to the sidebar. Receives `PluginSidebarProps` with `context.companyId` set to the active company. Requires the `ui.sidebar.register` capability.
#### `sidebarPanel`
Renders richer inline content in a dedicated panel area below the company sidebar navigation sections. Use this for mini-widgets, summary cards, quick-action panels, or at-a-glance status views that need more vertical space than a nav link. Receives `context.companyId` set to the active company via `useHostContext()`. Requires the `ui.sidebar.register` capability.
#### `settingsPage`
Replaces the auto-generated JSON Schema settings form with a custom React component. Use this when the default form is insufficient — for example, when your plugin needs multi-step configuration, OAuth flows, "Test Connection" buttons, or rich input controls. Receives `PluginSettingsPageProps` with `context.companyId` set to the active company. The component is responsible for reading and writing config through the bridge (via `usePluginData` and `usePluginAction`).
#### `dashboardWidget`
A card or section rendered on the main dashboard. Use this for at-a-glance metrics, status indicators, or summary views that surface plugin data alongside core Paperclip information. Receives `PluginWidgetProps` with `context.companyId` set to the active company. Requires the `ui.dashboardWidget.register` capability.
#### `detailTab`
An additional tab on a project, issue, agent, goal, or run detail page. Rendered when the user navigates to that entity's detail view. Receives `PluginDetailTabProps` with `context.companyId` set to the active company and `context.entityId` / `context.entityType` guaranteed to be non-null, so you can immediately scope data fetches to the relevant entity. Specify which entity types the tab applies to via the `entityTypes` array in the manifest slot declaration. Requires the `ui.detailTab.register` capability.
#### `taskDetailView`
A specialized slot rendered in the context of a task or issue detail view. Similar to `detailTab` but designed for inline content within the task detail layout rather than a separate tab. Receives `context.companyId`, `context.entityId`, and `context.entityType` like `detailTab`. Requires the `ui.detailTab.register` capability.
#### `projectSidebarItem`
A link or small component rendered **once per project** under that project's row in the sidebar Projects list. Use this to add project-scoped navigation entries (e.g. "Files", "Linear Sync") that deep-link into a plugin detail tab: `/:company/projects/:projectRef?tab=plugin:<key>:<slotId>`. Receives `PluginProjectSidebarItemProps` with `context.companyId` set to the active company, `context.entityId` set to the project id, and `context.entityType` set to `"project"`. Use the optional `order` field in the manifest slot to control sort position. Requires the `ui.sidebar.register` capability.
#### `toolbarButton`
A button rendered in the toolbar of a host surface (e.g. project detail, issue detail). Use this for short-lived, contextual actions like triggering a sync, opening a picker, or running a quick command. The component can open a plugin-owned modal internally for confirmations or compact forms. Receives `context.companyId` set to the active company; entity context varies by host surface. Requires the `ui.action.register` capability.
#### `contextMenuItem`
An entry added to a right-click or overflow context menu on a host surface. Use this for secondary actions that apply to the entity under the cursor (e.g. "Copy to Linear", "Re-run analysis"). Receives `context.companyId` set to the active company; entity context varies by host surface. Requires the `ui.action.register` capability.
#### `commentAnnotation`
A per-comment annotation region rendered below each individual comment in the issue detail timeline. Use this to augment comments with parsed file links, sentiment badges, inline actions, or any per-comment metadata. Receives `PluginCommentAnnotationProps` with `context.entityId` set to the comment UUID, `context.entityType` set to `"comment"`, `context.parentEntityId` set to the parent issue UUID, `context.projectId` set to the issue's project (if any), and `context.companyPrefix` set to the active company slug. Requires the `ui.commentAnnotation.register` capability.
#### `commentContextMenuItem`
A per-comment context menu item rendered in the "more" dropdown menu (⋮) on each comment in the issue detail timeline. Use this to add per-comment actions such as "Create sub-issue from comment", "Translate", "Flag for review", or custom plugin actions. Receives `PluginCommentContextMenuItemProps` with `context.entityId` set to the comment UUID, `context.entityType` set to `"comment"`, `context.parentEntityId` set to the parent issue UUID, `context.projectId` set to the issue's project (if any), and `context.companyPrefix` set to the active company slug. Plugins can open drawers, modals, or popovers scoped to that comment. The ⋮ menu button only appears on comments where at least one plugin renders visible content. Requires the `ui.action.register` capability.
### Launcher actions and render options

Full list in code: import `PLUGIN_CAPABILITIES` from `@paperclipai/plugin-sdk`.
## UI quick start
```tsx
import { usePluginData, usePluginAction } from "@paperclipai/plugin-sdk/ui";
export function DashboardWidget() {
const { data } = usePluginData<{ status: string }>("health");
const ping = usePluginAction("ping");
return (
<div style={{ display: "grid", gap: 8 }}>
<strong>Health</strong>
<div>{data?.status ?? "unknown"}</div>
<button onClick={() => void ping()}>Ping</button>
</div>
);
}
```
### Hooks reference
#### `usePluginData<T>(key, params?)`
Fetches data from the worker's registered `getData` handler. Re-fetches when `params` changes. Returns `{ data, loading, error, refresh }`.
```tsx
import { usePluginData } from "@paperclipai/plugin-sdk/ui";
interface SyncStatus {
lastSyncAt: string;
syncedCount: number;
healthy: boolean;
}
export function SyncStatusWidget({ context }: PluginWidgetProps) {
const { data, loading, error, refresh } = usePluginData<SyncStatus>("sync-status", {
companyId: context.companyId,
});
if (loading) return <div>Loading</div>;
if (error) return <div>Error: {error.message}</div>;
return (
<div>
<p>Status: {data!.healthy ? "Healthy" : "Unhealthy"}</p>
<p>Synced {data!.syncedCount} items</p>
<p>Last sync: {data!.lastSyncAt}</p>
<button onClick={refresh}>Refresh</button>
</div>
);
}
```
#### `usePluginAction(key)`
Returns an async function that calls the worker's `performAction` handler. Throws `PluginBridgeError` on failure.
```tsx
import { useState } from "react";
import { usePluginAction, type PluginBridgeError } from "@paperclipai/plugin-sdk/ui";
export function ResyncButton({ context }: PluginWidgetProps) {
const resync = usePluginAction("resync");
const [busy, setBusy] = useState(false);
const [error, setError] = useState<string | null>(null);
async function handleClick() {
setBusy(true);
setError(null);
try {
await resync({ companyId: context.companyId });
} catch (err) {
setError((err as PluginBridgeError).message);
} finally {
setBusy(false);
}
}
return (
<div>
<button onClick={handleClick} disabled={busy}>
{busy ? "Syncing..." : "Resync Now"}
</button>
{error && <p style={{ color: "red" }}>{error}</p>}
</div>
);
}
```
#### `useHostContext()`
Reads the active company, project, entity, and user context. Use this to scope data fetches and actions.
```tsx
import { useHostContext, usePluginData } from "@paperclipai/plugin-sdk/ui";
import type { PluginDetailTabProps } from "@paperclipai/plugin-sdk/ui";
export function IssueLinearLink({ context }: PluginDetailTabProps) {
const { companyId, entityId, entityType } = context;
const { data } = usePluginData<{ url: string }>("linear-link", {
companyId,
issueId: entityId,
});
if (!data?.url) return <p>No linked Linear issue.</p>;
return <a href={data.url} target="_blank" rel="noopener">View in Linear</a>;
}
```
#### `usePluginStream<T>(channel, options?)`
Subscribes to a real-time event stream pushed from the plugin worker via SSE. The worker pushes events using `ctx.streams.emit(channel, event)` and the hook receives them as they arrive. Returns `{ events, lastEvent, connecting, connected, error, close }`.
```tsx
import { usePluginStream } from "@paperclipai/plugin-sdk/ui";
interface ChatToken {
text: string;
}
export function ChatMessages({ context }: PluginWidgetProps) {
const { events, connected, close } = usePluginStream<ChatToken>("chat-stream", {
companyId: context.companyId ?? undefined,
});
return (
<div>
{events.map((e, i) => <span key={i}>{e.text}</span>)}
{connected && <span className="pulse" />}
<button onClick={close}>Stop</button>
</div>
);
}
```
The SSE connection targets `GET /api/plugins/:pluginId/bridge/stream/:channel?companyId=...`. The host bridge manages the EventSource lifecycle; `close()` terminates the connection.
### UI authoring note
The current host does **not** provide a real shared component library to plugins yet. Use normal React components, your own CSS, or your own small design primitives inside the plugin package.
### Slot component props
Each slot type receives a typed props object with `context: PluginHostContext`. Import from `@paperclipai/plugin-sdk/ui`.
| Slot type | Props interface | `context` extras |
|-----------|----------------|------------------|
| `page` | `PluginPageProps` | — |
| `sidebar` | `PluginSidebarProps` | — |
| `settingsPage` | `PluginSettingsPageProps` | — |
| `dashboardWidget` | `PluginWidgetProps` | — |
| `detailTab` | `PluginDetailTabProps` | `entityId: string`, `entityType: string` |
| `commentAnnotation` | `PluginCommentAnnotationProps` | `entityId: string`, `entityType: "comment"`, `parentEntityId: string`, `projectId`, `companyPrefix` |
| `commentContextMenuItem` | `PluginCommentContextMenuItemProps` | `entityId: string`, `entityType: "comment"`, `parentEntityId: string`, `projectId`, `companyPrefix` |
| `projectSidebarItem` | `PluginProjectSidebarItemProps` | `entityId: string`, `entityType: "project"` |
Example detail tab with entity context:
```tsx
import type { PluginDetailTabProps } from "@paperclipai/plugin-sdk/ui";
import { usePluginData } from "@paperclipai/plugin-sdk/ui";
export function AgentMetricsTab({ context }: PluginDetailTabProps) {
const { data, loading } = usePluginData<Record<string, string>>("agent-metrics", {
agentId: context.entityId,
companyId: context.companyId,
});
if (loading) return <div>Loading</div>;
if (!data) return <p>No metrics available.</p>;
return (
<dl>
{Object.entries(data).map(([label, value]) => (
<div key={label}>
<dt>{label}</dt>
<dd>{value}</dd>
</div>
))}
</dl>
);
}
```
## Launcher surfaces and modals
V1 does not provide a dedicated `modal` slot. Plugins can either:
- declare concrete UI mount points in `ui.slots`
- declare host-rendered entry points in `ui.launchers`
Supported launcher placement zones currently mirror the major host surfaces such as `projectSidebarItem`, `toolbarButton`, `detailTab`, `settingsPage`, and `contextMenuItem`. Plugins may still open their own local modal from those entry points when needed.
Declarative launcher example:
```json
{
"ui": {
"launchers": [
{
"id": "sync-project",
"displayName": "Sync",
"placementZone": "toolbarButton",
"entityTypes": ["project"],
"action": {
"type": "openDrawer",
"target": "sync-project"
},
"render": {
"environment": "hostOverlay",
"bounds": "wide"
}
}
]
}
}
```
The host returns launcher metadata from `GET /api/plugins/ui-contributions` alongside slot declarations.
When a launcher opens a host-owned overlay or page, `useHostContext()`,
`usePluginData()`, and `usePluginAction()` receive the current
`renderEnvironment` through the bridge. Use that to tailor compact modal UI vs.
full-page layouts without adding custom route parsing in the plugin.
## Project sidebar item
Plugins can add a link under each project in the sidebar via the `projectSidebarItem` slot. This is the recommended slot-based launcher pattern for project-scoped workflows because it can deep-link into a richer plugin tab. The component is rendered once per project with that projects id in `context.entityId`. Declare the slot and capability in your manifest:
```json
{
"ui": {
"slots": [
{
"type": "projectSidebarItem",
"id": "files",
"displayName": "Files",
"exportName": "FilesLink",
"entityTypes": ["project"]
}
]
},
"capabilities": ["ui.sidebar.register", "ui.detailTab.register"]
}
```
Minimal React component that links to the projects plugin tab (see project detail tabs in the spec):
```tsx
import type { PluginProjectSidebarItemProps } from "@paperclipai/plugin-sdk/ui";
export function FilesLink({ context }: PluginProjectSidebarItemProps) {
const projectId = context.entityId;
const prefix = context.companyPrefix ? `/${context.companyPrefix}` : "";
const projectRef = projectId; // or resolve from host; entityId is project id
return (
<a href={`${prefix}/projects/${projectRef}?tab=plugin:your-plugin:files`}>
Files
</a>
);
}
```
Use optional `order` in the slot to sort among other project sidebar items. See §19.5.1 in the plugin spec and project detail plugin tabs (§19.3) for the full flow.
## Toolbar launcher with a local modal
For short-lived actions, mount a `toolbarButton` and open a plugin-owned modal inside the component. Use `useHostContext()` to scope the action to the current company or project.
```json
{
"ui": {
"slots": [
{
"type": "toolbarButton",
"id": "sync-toolbar-button",
"displayName": "Sync",
"exportName": "SyncToolbarButton"
}
]
},
"capabilities": ["ui.action.register"]
}
```
```tsx
import { useState } from "react";
import {
useHostContext,
usePluginAction,
} from "@paperclipai/plugin-sdk/ui";
export function SyncToolbarButton() {
const context = useHostContext();
const syncProject = usePluginAction("sync-project");
const [open, setOpen] = useState(false);
const [submitting, setSubmitting] = useState(false);
const [errorMessage, setErrorMessage] = useState<string | null>(null);
async function confirm() {
if (!context.projectId) return;
setSubmitting(true);
setErrorMessage(null);
try {
await syncProject({ projectId: context.projectId });
setOpen(false);
} catch (err) {
setErrorMessage(err instanceof Error ? err.message : "Sync failed");
} finally {
setSubmitting(false);
}
}
return (
<>
<button type="button" onClick={() => setOpen(true)}>
Sync
</button>
{open ? (
<div
role="dialog"
aria-modal="true"
className="fixed inset-0 z-50 flex items-center justify-center bg-black/40 p-4"
onClick={() => !submitting && setOpen(false)}
>
<div
className="w-full max-w-md rounded-lg bg-background p-4 shadow-xl"
onClick={(event) => event.stopPropagation()}
>
<h2 className="text-base font-semibold">Sync this project?</h2>
<p className="mt-2 text-sm text-muted-foreground">
Queue a sync for <code>{context.projectId}</code>.
</p>
{errorMessage ? (
<p className="mt-2 text-sm text-destructive">{errorMessage}</p>
) : null}
<div className="mt-4 flex justify-end gap-2">
<button type="button" onClick={() => setOpen(false)}>
Cancel
</button>
<button type="button" onClick={() => void confirm()} disabled={submitting}>
{submitting ? "Running…" : "Run sync"}
</button>
</div>
</div>
</div>
) : null}
</>
);
}
```
Prefer deep-linkable tabs and pages for primary workflows. Reserve plugin-owned modals for confirmations, pickers, and compact editors.
## Real-time streaming (`ctx.streams`)
Plugins can push real-time events from the worker to the UI using server-sent events (SSE). This is useful for streaming LLM tokens, live sync progress, or any push-based data.
### Worker side
In `setup()`, use `ctx.streams` to open a channel, emit events, and close when done:
```ts
const plugin = definePlugin({
async setup(ctx) {
ctx.actions.register("chat", async (params) => {
const companyId = params.companyId as string;
ctx.streams.open("chat-stream", companyId);
for await (const token of streamFromLLM(params.prompt as string)) {
ctx.streams.emit("chat-stream", { text: token });
}
ctx.streams.close("chat-stream");
return { ok: true };
});
},
});
```
**API:**
| Method | Description |
|--------|-------------|
| `ctx.streams.open(channel, companyId)` | Open a named stream channel and associate it with a company. Sends a `streams.open` notification to the host. |
| `ctx.streams.emit(channel, event)` | Push an event to the channel. The `companyId` is automatically resolved from the prior `open()` call. |
| `ctx.streams.close(channel)` | Close the channel and clear the company mapping. Sends a `streams.close` notification. |
Stream notifications are fire-and-forget JSON-RPC messages (no `id` field). They are sent via `notifyHost()` synchronously during handler execution.
### UI side
Use the `usePluginStream` hook (see [Hooks reference](#usepluginstreamtchannel-options) above) to subscribe to events from the UI.
### Host-side architecture
The host maintains an in-memory `PluginStreamBus` that fans out worker notifications to connected SSE clients:
1. Worker emits `streams.emit` notification via stdout
2. Host (`plugin-worker-manager`) receives the notification and publishes to `PluginStreamBus`
3. SSE endpoint (`GET /api/plugins/:pluginId/bridge/stream/:channel?companyId=...`) subscribes to the bus and writes events to the response
The bus is keyed by `pluginId:channel:companyId`, so multiple UI clients can subscribe to the same stream independently.
### Streaming agent responses to the UI
`ctx.streams` and `ctx.agents.sessions` are complementary. The worker sits between them, relaying agent events to the browser in real time:
```
UI ──usePluginAction──▶ Worker ──sessions.sendMessage──▶ Agent
UI ◀──usePluginStream── Worker ◀──onEvent callback────── Agent
```
The agent doesn't know about streams — the worker decides what to relay. Encode the agent ID in the channel name to scope streams per agent.
**Worker:**
```ts
ctx.actions.register("ask-agent", async (params) => {
const { agentId, companyId, prompt } = params as {
agentId: string; companyId: string; prompt: string;
};
const channel = `agent:${agentId}`;
ctx.streams.open(channel, companyId);
const session = await ctx.agents.sessions.create(agentId, companyId);
await ctx.agents.sessions.sendMessage(session.sessionId, companyId, {
prompt,
onEvent: (event) => {
ctx.streams.emit(channel, {
type: event.eventType, // "chunk" | "done" | "error"
text: event.message ?? "",
});
},
});
ctx.streams.close(channel);
return { sessionId: session.sessionId };
});
```
**UI:**
```tsx
import { useState } from "react";
import { usePluginAction, usePluginStream } from "@paperclipai/plugin-sdk/ui";
interface AgentEvent {
type: "chunk" | "done" | "error";
text: string;
}
export function AgentChat({ agentId, companyId }: { agentId: string; companyId: string }) {
const askAgent = usePluginAction("ask-agent");
const { events, connected, close } = usePluginStream<AgentEvent>(`agent:${agentId}`, { companyId });
const [prompt, setPrompt] = useState("");
async function send() {
setPrompt("");
await askAgent({ agentId, companyId, prompt });
}
return (
<div>
<div>{events.filter(e => e.type === "chunk").map((e, i) => <span key={i}>{e.text}</span>)}</div>
<input value={prompt} onChange={(e) => setPrompt(e.target.value)} />
<button onClick={send}>Send</button>
{connected && <button onClick={close}>Stop</button>}
</div>
);
}
```
## Agent sessions (two-way chat)
Plugins can hold multi-turn conversational sessions with agents:
```ts
// Create a session
const session = await ctx.agents.sessions.create(agentId, companyId);
// Send a message and stream the response
await ctx.agents.sessions.sendMessage(session.sessionId, companyId, {
prompt: "Help me triage this issue",
onEvent: (event) => {
if (event.eventType === "chunk") console.log(event.message);
if (event.eventType === "done") console.log("Stream complete");
},
});
// List active sessions
const sessions = await ctx.agents.sessions.list(agentId, companyId);
// Close when done
await ctx.agents.sessions.close(session.sessionId, companyId);
```
Requires capabilities: `agent.sessions.create`, `agent.sessions.list`, `agent.sessions.send`, `agent.sessions.close`.
Exported types: `AgentSession`, `AgentSessionEvent`, `AgentSessionSendResult`, `PluginAgentSessionsClient`.
## Testing utilities
```ts
import { createTestHarness } from "@paperclipai/plugin-sdk/testing";
import plugin from "../src/worker.js";
import manifest from "../src/manifest.js";
const harness = createTestHarness({ manifest });
await plugin.definition.setup(harness.ctx);
await harness.emit("issue.created", { issueId: "iss_1" }, { entityId: "iss_1", entityType: "issue" });
```
## Bundler presets
```ts
import { createPluginBundlerPresets } from "@paperclipai/plugin-sdk/bundlers";
const presets = createPluginBundlerPresets({ uiEntry: "src/ui/index.tsx" });
// presets.esbuild.worker / presets.esbuild.manifest / presets.esbuild.ui
// presets.rollup.worker / presets.rollup.manifest / presets.rollup.ui
```
## Local dev server (hot-reload events)
```bash
paperclip-plugin-dev-server --root . --ui-dir dist/ui --port 4177
```
Or programmatically:
```ts
import { startPluginDevServer } from "@paperclipai/plugin-sdk/dev-server";
const server = await startPluginDevServer({ rootDir: process.cwd() });
```
Dev server endpoints:
- `GET /__paperclip__/health` returns `{ ok, rootDir, uiDir }`
- `GET /__paperclip__/events` streams `reload` SSE events on UI build changes

/**
* Host-side client factory — creates capability-gated handler maps for
* servicing worker→host JSON-RPC calls.
*
* When a plugin worker calls `ctx.state.get(...)` inside its process, the
* SDK serializes the call as a JSON-RPC request over stdio. On the host side,
* the `PluginWorkerManager` receives the request and dispatches it to the
* handler registered for that method. This module provides a factory that
* creates those handlers for all `WorkerToHostMethods`, with automatic
* capability enforcement.
*
* ## Design
*
* 1. **Capability gating**: Each handler checks the plugin's declared
* capabilities before executing. If the plugin lacks a required capability,
* the handler throws a `CapabilityDeniedError` (which the worker manager
* translates into a JSON-RPC error response with code
* `CAPABILITY_DENIED`).
*
* 2. **Service adapters**: The caller provides a `HostServices` object with
* concrete implementations of each platform service. The factory wires
* each handler to the appropriate service method.
*
* 3. **Type safety**: The returned handler map is typed as
* `WorkerToHostHandlers` (from `plugin-worker-manager.ts`) so it plugs
* directly into `WorkerStartOptions.hostHandlers`.
*
* @example
* ```ts
* const handlers = createHostClientHandlers({
* pluginId: "acme.linear",
* capabilities: manifest.capabilities,
* services: {
* config: { get: () => registry.getConfig(pluginId) },
* state: { get: ..., set: ..., delete: ... },
* entities: { upsert: ..., list: ... },
* // ... all services
* },
* });
*
* await workerManager.startWorker("acme.linear", {
* // ...
* hostHandlers: handlers,
* });
* ```

* @fileoverview Plugin UI static file serving route
*
* Serves plugin UI bundles from the plugin's dist/ui/ directory under the
* `/_plugins/:pluginId/ui/*` namespace. This is specified in PLUGIN_SPEC.md
* §19.0.3 (Bundle Serving).
*
* Plugin UI bundles are pre-built ESM that the host serves as static assets.
* The host dynamically imports the plugin's UI entry module from this path,
* resolves the named export declared in `ui.slots[].exportName`, and mounts
* it into the extension slot.
*
* Security:
* - Path traversal is prevented by resolving the requested path and verifying
* it stays within the plugin's UI directory.
* - Only plugins in 'ready' status have their UI served.
* - Only plugins that declare `entrypoints.ui` serve UI bundles.
*
* Cache Headers:
* - Files with content-hash patterns in their name (e.g., `index-a1b2c3d4.js`)
* receive `Cache-Control: public, max-age=31536000, immutable`.
* - Other files receive `Cache-Control: public, max-age=0, must-revalidate`
* with ETag-based conditional request support.
