@anonymous-dev/0x0-nvim-completion is the inline completion plugin. It is separate from chat. It watches insert-mode context, sends prefix and suffix text to the 0x0 server, and renders the response as ghost text.

​

​
Excluded Filetypes

The plugin does not request completions in noisy prompt or utility buffers by default: 
{ "TelescopePrompt", "NvimTree", "help", "qf", "alpha", "dashboard" }

​
API Surface

The plugin uses POST /completions or the WebSocket completion message. The request contains:
  • prefix
  • suffix
  • language
  • filepath
  • Optional provider and model overrides
Completion is intentionally narrow. It does not manage chat history, agent sessions, or review state.
