## What relay does, in the publisher's words

This is the editable source for Relay's coding-agent guidance and generated Codex and Cursor distributions.

The Relay skill teaches the locked Relay v1 contract: Agent Tokens, signed Webhooks, acknowledged WebSocket delivery, Chats, Messages, ordered parts, Attachments, receipts, groups, Add requests, retries, and errors.

The repository is also a portable Agent Plugin and a Claude Code plugin. The dedicated Codex and Cursor repositories are generated from this source so their host-specific layouts never become independent editable copies.

From the project README, punctuation lightly normalized. Full text: https://raw.githubusercontent.com/RelayMessenger/Relay-Skills/HEAD/README.md

## Skills

- relay: Implement, debug, or review a Relay v1 agent backend, Webhook receiver, WebSocket consumer, messaging flow, or @relaymessenger/sdk integration.

Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized.

## MCP servers
