Sidekick: keep using neovim while a dozen agents rewrite your code
Summary
Sidekick enables AI-assisted coding in Neovim by acting as a conduit between the editor and agents. It blocks edits when there are unsaved changes, auto-reloads buffers after AI edits, and can inject the current visual selection into prompts. The project is open source and offers per-tool integration with Claude Code, Codex, opencode, pi, and Crush, with install and health-check commands.
