 ```
 
 - **No build step, no dependencies, no tests.** The plugin is entirely declarative.
-- `.mcp.json` routes the `intercom` namespace to the remote HTTP-based MCP server.
+- `.claude-plugin/plugin.json` declares the `intercom` MCP server inline. Don't add a `.mcp.json`: Antigravity never loads it, and `agy plugin validate --strict` fails on it.
 - `.claude-plugin/plugin.json` is the plugin manifest for Claude Code's plugin registry.
+- `.antigravity-plugin/plugin.json` is the Antigravity Plugin Marketplace manifest. Antigravity reads MCP servers from `mcp_config.json` and the card logo from `assets/logo.svg`, both at the repo root.
+- Keep `version` in both manifests in step, and bump it on every published change so installed clients pick up the update.
+- The company is Fin and Intercom is its helpdesk product: use Fin for the publisher (`author`) and Intercom for the product and its features.
 - `.claude/settings.local.json` manages local permissions (currently allows WebFetch from raw.githubusercontent.com).

-Connect your Intercom workspace to Claude Code. Search conversations, analyze customer support patterns, look up contacts and companies, and install the Intercom Messenger — all from your terminal.
+Connect your Intercom workspace to Claude Code or Google Antigravity. Search conversations, analyze customer support patterns, look up contacts and companies, and install the Intercom Messenger.
 
 ## Prerequisites
 
 - An [Intercom](https://www.intercom.com) workspace
-- [Claude Code](https://docs.anthropic.com/en/docs/claude-code) CLI installed
+- [Claude Code](https://docs.anthropic.com/en/docs/claude-code) or [Google Antigravity](https://antigravity.google) installed
 - Your Intercom workspace must be US-hosted (EU and AU support coming soon)
 
 ## Installation
 
+### Claude Code
+
 ```
 /plugin install intercom
 ```
 
+### Google Antigravity
+
+Open **Customizations → Plugins** and install Intercom from **Discover**, or choose **+ Install from URL** and enter `https://github.com/intercom/claude-plugin-external`.
+
+Connecting to the Intercom MCP server requires signing in to your Intercom workspace through OAuth. In Antigravity, explicit skills are invoked without the `intercom:` prefix, for example `/customer-360 jane@example.com`.
