XMTP Documentation Lookup

Query current XMTP documentation to find accurate SDK patterns before writing code.

Why This Skill Exists

CRITICAL: Never use training data for XMTP SDK methods. The SDK evolves frequently and method names change between versions. All method names, signatures, and patterns MUST be looked up from current documentation.

How to Query

Step 1: Find the right page

Use the docs index to find which page has what you need:

WebFetch({
  url: "https://docs.xmtp.org/llms.txt",
  prompt: "Find the page URL for [topic]"
})

Step 2: Fetch that page

Fetch the specific page for complete code examples:

WebFetch({
  url: "https://docs.xmtp.org[path-from-step-1]",
  prompt: "Extract [specific feature] with code examples"
})

Examples

Find how to create a client:

WebFetch({ url: "https://docs.xmtp.org/llms.txt", prompt: "Find the page URL for creating an XMTP client" })
// Returns: /chat-apps/core-messaging/create-a-client

WebFetch({ url: "https://docs.xmtp.org/chat-apps/core-messaging/create-a-client", prompt: "Extract how to create a client with code examples" })

Find how to stream messages:

WebFetch({ url: "https://docs.xmtp.org/llms.txt", prompt: "Find the page URL for streaming messages" })
// Returns: /chat-apps/list-stream-sync/stream

WebFetch({ url: "https://docs.xmtp.org/chat-apps/list-stream-sync/stream", prompt: "Extract streaming patterns with code examples" })

Tips

1. Always use the index first – Don’t guess URLs; they change when docs reorganize
2. Ask for code examples – Docs include examples for Browser, Node, Kotlin, and Swift
3. One topic per query – Focused queries return better results
4. Don’t use llms-full.txt – It’s 500KB+ and WebFetch can’t reliably search it
