Channels SDK Brings Agents to Slack and Teams
CopilotKit released an open-source Channels SDK (TypeScript) that lets any AG-UI-compatible agent run on multiple messaging channels (Slack, Microsoft Teams, Discord, Telegram, WhatsApp) from a single codebase. The SDK decouples app and agent via the AG-UI protocol, supports a BuiltInAgent (or external agent frameworks), and interoperates with hosted or local models (OpenAI, Anthropic, Google, Ollama, etc.). It provides native UI components, generative cards, tooling hooks, MCP integration (Notion example), human-in-the-loop approvals, file/image handling, and cross-platform transcripts. CopilotKit also offers a managed production path (CopilotKit Intelligence) that holds platform connections and delivers turns to user runtimes, plus documentation, examples, and a GitHub repo for a complete working example.
Technical SDK release that simplifies deploying LLM agents across chat platforms; useful for MarTech/Support automation but not industry-shifting for core AdTech/MarTech infrastructure.

Key Takeaways & Evidence Grounding
- CopilotKit released an open-source Channels SDK (TypeScript) to bring AG-UI agents to multiple chat channels from one codebase.
- Channels SDK is built on the AG-UI protocol and supports swapping agent frameworks or using a BuiltInAgent that works with OpenAI, Anthropic, Google, or local endpoints (e.g., Ollama).
- CopilotKit provides a managed production path called CopilotKit Intelligence that holds Slack and Microsoft Teams connections and delivers message turns to the app.
- The SDK includes a Channels UI component library for native cards, support for tools via defineChannelTool, MCP integration (Notion example), human-in-the-loop approvals, file/image handling, and cross-platform transcripts.
- Repository and examples are published on GitHub (CopilotKit/OpenTag and copilotKit/channels-sdk) and docs are available on copilotkit.ai.

Recent verified developments and strategic activity across this market segment.
Open Agent SDK (Swift) Adds Native Swift Concurrency
Open Agent SDK (Swift) is an open-source Swift 6.1 SDK (requires macOS 13+) that implements a complete in-process AI Agent Loop driven by native Swift concurrency (async/await, AsyncStream). The SDK provides 34 built-in tools, an LLMClient abstraction with support for Anthropic and OpenAI-compatible endpoints (GLM, Ollama, OpenRouter, etc.), MCP server integration, multi-agent collaboration, session persistence, a hook registry, permissions/sandboxing, and a skills system. The project is published on GitHub under the MIT license, includes ~31 example projects and nine modules, and was announced on DEV Community on 2026-04-27.
Everything Is CLI: Agent-Native CLIs Gain Momentum
The newsletter documents a clear shift toward CLI-first workflows for agent-native infrastructure, highlighted by Stripe's Projects.dev which provisions third-party services via simple CLI commands (e.g., creating a PostHog account and billing). Multiple vendors released or announced CLIs the same week (Ramp, Sendblue, ElevenLabs, Visa, Resend, Google Workspace and others), reinforcing a trend away from heavier MCP-style integrations. The issue also summarizes major model and tooling launches: Google’s Gemini 3.1 Flash Live (real-time voice+vision), Mistral’s Voxtral TTS, Cohere Transcribe (open-source ASR), and OpenAI’s GPT-5.4 mini/nano variants. Broader themes include rising importance of agent “harness” engineering, multi-agent orchestration interfaces (Cline Kanban), infrastructure-level training patterns (ProRL Agent), and research advances like Attention Residuals and compression work (TurboQuant).
Agent-First Coding Tools and Agent Infrastructure Surge
A Latent Space AINews roundup (published 2026-05-15) summarizes a wave of agent-first coding tooling and agent infrastructure updates. Major product moves include GitHub’s Copilot App technical preview and OpenAI integrating Codex into the ChatGPT mobile app (with Remote SSH, hooks, and programmatic tokens). LangChain released SmithDB and the LangSmith Engine and announced LangChain Labs to operationalize continual learning from production agent traces. Anthropic tightened Claude Code usage, prompting developer backlash and subscription cancellations. Robotics firm Figure livestreamed 24+ hours of autonomous sorting on Helix-02. The issue also highlights research/model releases (Zyphra diffusion LM preview, Datadog’s Toto 2.0 time‑series models) and discussions about agent orchestration, execution isolation, and the evolving economics of subscription-backed agent workflows.
