## Summary
Lets the `@copilotkit/bot` SDK run from **Intelligence-delivered
events** without a second programming model, and adds the runtime `bots`
declaration API. A managed event (delivered by Intelligence) runs the
*same* customer handlers, tools, context, commands, Bot UI, and agents
as local/custom adapters — the managed path is "just another
`PlatformAdapter`," fed by injected transports.
This is the **OSS / SDK slice** of the Hosted Managed Bots work. The
credentialed transports (Realtime Gateway, Connector Outbox) and the
frozen shared contracts live elsewhere (see *Out of scope*); this PR
ships the seams they plug into, fully runnable headless.
Relates to **OSS-360** (runtime bots API), **OSS-361** (run the SDK from
Intelligence events), **OSS-363** (Slack render/codec reuse).
## What's in here
- **`intelligenceAdapter()` bridge** (`@internal`, not publicly
documented) — implements `PlatformAdapter` over two injected transports:
`DeliverySource` (inbound) + `EgressSink` (outbound). Ingress →
`onTurn`/`onCommand`/`onInteraction`/`onThreadStarted`/`onReaction`; ack
on success / nack on throw (at-least-once). Egress emits generic
operations carrying `BotNode[]` IR with **deterministic ids**
(`turnId:seq`, reset per turn) so a redelivered turn reproduces the same
ids for the Connector Outbox to dedupe. Idempotency lives at egress, so
the managed path skips ingress dedup (`skipIngressDedup`) — a redelivery
re-runs rather than being dropped.
- **Runtime `bots` API** — `new CopilotRuntime({ intelligence, bots })`,
accepted by TypeScript **only when `intelligence` is configured**
(discriminated union). `createBot({ name })`; `startManagedBots()`
validates names (required, identifier-style, unique — fail-loud), builds
activation metadata, and wires each bot to its resolved transport.
- **`PlatformCodec` seam** + Slack egress codec (`slackCodec`) composing
the existing pure `renderSlackMessage`, so IR→native rendering is shared
(no Bolt/creds) instead of duplicated.
- **Backwards-compatible SDK foundations**: `bot.addAdapter()` +
optional `adapters`, deferred backend resolution at `start()` with
`stateStore`-provider precedence (+ multi-provider warning),
`bot.transcripts` throws pre-start, optional
`eventId`/`turnId`/`deliveryId` on ingress + handler context. Existing
`createBot` callers and every `PlatformAdapter` implementer are
unaffected.
- **In-memory transports + fixture tests** — the full dispatch path
(envelope in → handler runs → egress op out) runs with zero
Slack/Intelligence/network.
## Out of scope (external / separate tickets)
- **Realtime Gateway + Connector Outbox transports** — implemented in
the closed-source repo against the `DeliverySource`/`EgressSink`
interfaces shipped here.
- **Shared contracts freeze (OSS-377)** — consumed here via a minimal,
isolated placeholder (`managed/contracts.ts`, marked `TODO(OSS-377)`);
swaps in via one import change.
- **OSS-363 ingress normalization** — the egress codec is done;
extracting the pure Slack event→neutral mapping out of the Bolt listener
(so local + Intelligence ingress share it) is the remaining, higher-risk
half and is left to that ticket (`TODO(OSS-363)`).
## Testing
TDD throughout (RED→GREEN per behavior). New: managed adapter
dispatch/ack-nack/ids/run-renderer/exclusivity, all-kinds routing, name
validation + metadata + lifecycle, runtime `bots` option, Slack codec.
Full suites green: `bot` 147, `bot-slack` 256, `runtime` 1574. All
builds typecheck (`bot`/`bot-slack`/`bot-discord`/`runtime`);
oxlint/oxfmt clean.

CopilotKit
Build agent-native applications — on any framework, on any surface.
Generative UI, shared state, and human-in-the-loop workflows for React, Angular, Vue, React Native — and beyond the browser.
What is CopilotKit
CopilotKit is a best-in-class SDK for building full-stack agentic applications, Generative UI, and chat applications.
What started as a React library is now a multi-platform agentic framework: the same agent can power your web app, your mobile app, and your team's Slack workspace.
We are the company behind the AG-UI Protocol - adopted by Google, LangChain, AWS, Microsoft, Mastra, PydanticAI, and more!
Quick Start
Up and running in under five minutes. All you need is an LLM key (OpenAI, Anthropic, Gemini, etc.).
npx copilotkit@latest create
Agent Skills
CopilotKit ships agent skills that teach your coding agent (Claude Code, Codex, Cursor, Gemini, and others) how to set up, build with, integrate, debug, and upgrade CopilotKit.
Install them into any project directory:
npx copilotkit@latest skills install
Run it again any time to refresh to the latest skills.
Bring Your App to Life
https://github.com/user-attachments/assets/72b7b4f3-b6e7-460c-a932-5746fe3c8db3
Features:
- Chat UI – A fully customizable chat interface that supports message streaming, tool calls, and agent responses.
- Backend Tool Rendering – Enables agents to call backend tools that return UI components rendered directly in the client.
- Generative UI – Allows agents to generate and update UI components dynamically at runtime based on user intent and agent state.
- Shared State – A synchronized state layer that both agents and UI components can read from and write to in real time.
- Human-in-the-Loop – Lets agents pause execution to request user input, confirmation, or edits before continuing.
- Self-Learning (early access) – Agents that continuously improve from user feedback via in-context reinforcement learning (CLHF).
🧩 Works With Your Stack
One agent backend. Every frontend.
| Platform | Status | Get Started |
|---|---|---|
| ⚛️ React / Next.js | ✅ GA | Quickstart |
| 🅰️ Angular | ✅ Supported | Source Code - Quickstart coming soon |
| 💚 Vue | ✅ Supported | Source Code - Quickstart coming soon |
| 📱 React Native | ✅ Supported | Quickstart |
| 💬 Slack / MS Teams / Discord / Google Chat | 🟡 Beta | Request early access |
Your agent logic stays the same — AG-UI handles the wire protocol, CopilotKit handles the UI layer for each framework.
💬 Beyond the Browser: Slack & Microsoft Teams (Discord, Google Chat coming soon...)
Your agents can run and generate Generative UI beyond the web app (Learn more).
CopilotKit now lets you deploy the same agent to the places your users already work:
- Slack – Agents as first-class Slack apps: threads, tool calls, and human-in-the-loop approvals right in the channel.
- Microsoft Teams – Bring agentic workflows to the enterprise, where your org already lives.
🔒 Early access: We're onboarding teams now.
🧠 Self-Learning Agents
Improve your product by learning over time.
With Continuous Learning from Human Feedback (CLHF), part of the CopilotKit Intelligence Platform, agents improve with every interaction:
- In-context reinforcement learning – Agents automatically improve from user interactions, no model fine-tuning required.
- Automatic prompt augmentation – Agent behavior adapts based on recent interactions and outcomes.
- Per-user adaptation – Agents learn individual preferences and get better for each user over time.
- Threads & persistence – Full interaction history — generative UI, human-in-the-loop, shared state — captured across sessions.
Available via CopilotKit Cloud or self-hosted.
🔒 Early access: We're onboarding teams now.

What this gives you:
- CopilotKit installed – Core packages are fully set up in your app
- Provider configured – Context, state, and hooks ready to use
- Agent <> UI connected – Agents can stream actions and render UI immediately
- Deployment-ready – Your app is ready to deploy
Complete getting started guide →
How it works:
CopilotKit connects your UI, agents, and tools into a single interaction loop.
This enables:
- Agents that ask users for input
- Tools that render UI
- Stateful workflows across steps and sessions
- One agent, deployed across web, mobile, and chat platforms
⭐️ useAgent Hook
The useAgent hook sits directly on AG-UI, giving you full programmatic control over the agent connection.
// Programmatically access and control your agents
const { agent } = useAgent({ agentId: "my_agent" });
// Render and update your agent's state
return <div>
<h1>{agent.state.city}</h1>
<button onClick={() => agent.setState({ city: "NYC" })}>
Set City
</button>
</div>
Check out the useAgent docs to learn more.

Generative UI
Generative UI is a core CopilotKit pattern that allows agents to dynamically render UI as part of their workflow.
