@anonymous-dev/0x0-contracts is the shared schema package. It defines the request, response, stream, session, and WebSocket message shapes used by the server and editor clients.

Why It Exists

0x0 is modular by design. @anonymous-dev/0x0-server, @anonymous-dev/0x0-nvim-chat, @anonymous-dev/0x0-nvim-completion, and any future client should agree on one typed protocol. Use this package instead of copying payload shapes into each client.

​
Example

import { ChatRequestSchema } from "@anonymous-dev/0x0-contracts"

const request = ChatRequestSchema.parse({
  provider: "codex",
  model: "gpt-5.4-mini",
  messages: [{ role: "user", content: "Explain this file." }],
})
