SKILL.md

Build Google Chat bots, webhooks, and interactive forms with Cards v2, Spaces/Members/Reactions APIs, and bearer token verification.

Supports two integration modes: incoming webhooks for one-way notifications and HTTP endpoints for interactive bots with button clicks and form submissions

Cards v2 with Markdown and HTML formatting, 15+ widget types (text, buttons, inputs, date pickers), and 100-widget-per-card limit

Spaces API for creating/listing/searching spaces, Members API for managing membership and roles, and Reactions API for emoji reactions

Includes bearer token verification templates, form validation patterns, rate limit handling (3,000 reads/min, 60 space writes/min), and troubleshooting for six common issues

Cloudflare Workers recommended; Web Crypto API required for token verification; no official npm package—use fetch API directly
