From the project's own README (excerpt, reproduced for discovery under its MIT license):
Chat SDK
Unified TypeScript SDK for building chat bots across Slack, Microsoft Teams, Google Chat, Discord, Telegram, GitHub, Linear, WhatsApp, and more. Write your bot logic once, deploy everywhere.
Installation
Install one or more adapters for your platforms:
CLI
Scaffold a minimal Next.js bot app with create-chat-sdk:
The CLI generates your Chat configuration, webhook route, .env.example file, dependencies, and optional Web adapter route from the adapter catalog. See the CLI docs for options and non-interactive usage.
Usage
See the Getting Started guide for a full walkthrough.
Adapters

Features • Event handlers — mentions, messages, reactions, button clicks, slash commands, modals • AI streaming — stream LLM responses with native Slack streaming, Telegram private chat draft previews, and post+edit fallback • Cards — JSX-based interactive cards (Block Kit, Adaptive Cards, Google Chat Cards) • Actions — handle button clicks and dropdown selections • Modals — form dialogs with text inputs, dropdowns, and validation • Slash commands — handle /command invocations • Emoji — type-safe, cross-platform emoji with custom emoji support • File uploads — send and receive file attachments • Direct messages — initiate DMs programmatically • Ephemeral messages — user-only visible messages with DM fallback • Overlapping messages - burst, queue, debounce, drop, or process concurrent messages on the same thread
AI Coding Agents

No endorsements yetNo verified confirmations yet — be the first.
Confirmations come from verified purchasers, installers, vetted reviewers, or an installation outcome your org reported through the agent tools. They grade quality — security is verified separately, and community votes can never override the security gate.

04Trust Passport
Full passport →0/0 automated components pass. An automated score is never a security guarantee.
This listing is unclaimed, so publisher identity cannot be verified and it stays below the “verified” tier by design — that is a statement about the listing, not about the project’s quality. Our automated scans still ran; a maintainer who claims it unlocks identity verification.
