sidekick.nvim is a Neovim plugin that bridges your editor with AI coding assistants. It integrates Copilot LSP’s Next Edit Suggestions feature with a built-in terminal for any AI CLI tool, supporting Claude, Gemini, Grok, Codex, and Copilot CLI out of the box. The plugin provides context-aware prompts that automatically include file content, cursor position, and diagnostics, along with a library of pre-defined prompts for common development tasks like explaining code, fixing issues, or writing tests.
