@anonymous-dev/0x0-server is the local runtime for AI-powered developer tools. It exposes one provider layer over OpenAI and Anthropic models. The primary app surfaces are server chat and server completions. Clients can call them through HTTP for simple requests or WebSocket for editor sessions, agent turns, cancellation, and change review.

​
What It Provides

  • Provider discovery through GET /providers
  • Streaming chat through POST /chat
  • One-shot code completion through POST /completions
  • One-shot inline edits through POST /inline-edit
  • Git-backed agent sessions over /ws
  • Worktree-based change review with accept and discard operations

​
