Introduces the Chat SDK, a TypeScript library that enables developers to build bots that work across multiple messaging platforms (Slack, Microsoft Teams, Google Chat, Discord, Telegram, GitHub, and Linear) from a single codebase. It abstracts platform-specific integration logic and inconsistencies through adapters, allowing for a 'write once, deploy everywhere' approach. The SDK handles streaming, formatting, table rendering, cards, modals, and buttons, with pluggable state adapters for Redis and PostgreSQL. It also adds support for WhatsApp. The Chat SDK integrates directly with AI SDK text streams for piping LLM responses to chat platforms.
