Quick Inline Suggestion
VS Code extension that brings AI-powered code editing into your editor — select code, hit Cmd+I, describe the change, review the diff.
Supports Claude Code and OpenAI Codex CLI as backends.
Motivation
Recently, VS Code's built-in AI features have become increasingly bulky. I only wanted the simple inline suggestion workflow from VS Code Copilot: select code, ask for a change, review it, and apply it. So I built this plugin together with Claude Code to keep that experience lightweight and focused.
Features
- Inline edit —
Cmd+I opens an input box, describe what you want, AI returns the modified code
- Diff preview — review changes side-by-side before applying
- WorkspaceEdit apply — accepted changes are applied via VS Code's native edit API, keeping undo history intact
- Project-aware — the AI agent runs with the workspace as
cwd, so it sees your full project context
- Question mode — ask "what does this do?" and get an explanation in a new document
- Configurable backend — switch between Claude Code and Codex CLI in settings
Requirements
Usage
- Select code in the editor (or place cursor — empty selection sends the whole file)
- Press
Cmd+I (macOS) / Ctrl+I (Windows/Linux) — Cmd+Shift+I / Ctrl+Shift+I as fallback
- Type what you want (e.g. "convert to async/await", "add error handling", "what does this function do?")
- For edits: review the diff. For questions: read the explanation in the new document.
Keybinding conflicts
Official GitHub Copilot and some other extensions also bind Ctrl+I. If the shortcut doesn't work, use Ctrl+Shift+I or run Quick: Inline Edit from the command palette.
Extension Settings
quick-inline-suggestion.backend: Choose the AI backend — claude (Claude Code, default) or codex (OpenAI Codex CLI)
Installation
Search Quick Inline Suggestion or download from the VS Code Marketplace.
Architecture
Cmd+I → InputBox (instruction) → spawn AI CLI → extract code block → vscode.diff → WorkspaceEdit
