Send to Copilot CLI

Compose prompts in VS Code. Send them to your Copilot CLI session with one click.

Why?

Writing prompts directly in the terminal is awkward. One accidental Enter and your half-finished prompt is sent. You can't easily select, rearrange, or paste code snippets. And if you're building a multi-line prompt with context from multiple files, the terminal input line just isn't built for that.

This extension lets you write your prompts in a VS Code editor — a virtual/scratch document, an untitled file, or any file you have open — and send the content (or a selection) straight into your active Copilot CLI session. You get all the editing power of VS Code (multi-cursor, find & replace, snippets) for crafting the perfect prompt, and the CLI gets the final result.

How it works

The extension pairs with a small CLI bridge extension that runs inside your Copilot CLI session. When the CLI starts, the bridge opens a local connection and registers itself. When you send text from VS Code, the extension discovers the bridge and injects your prompt into the active session using session.send() from the Copilot CLI SDK.

The bridge is a lightweight Copilot CLI extension, which is a single .mjs file that the CLI loads automatically. No npm install required; the CLI runtime resolves @github/copilot-sdk on its own.

Getting started

1. Install the VS Code extension

Install Send to Copilot CLI from the VS Code Marketplace (or build from source).

2. Install the CLI bridge extension

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run:

Send to Copilot CLI: Install Bridge Extension

You'll be asked where to install:

3. Start a CLI session

Open a terminal and start the Copilot CLI (copilot). The bridge extension loads automatically and you'll see:

🔗 VS Code prompt bridge ready

4. Send your prompt

1. Open (or create) a file in VS Code (an untitled scratch file works great)
2. Write your prompt
3. Right-click → Send to Copilot CLI → Send Selection, or use the Command Palette
4. Your prompt appears in the CLI session

Tip: If nothing is selected, the Send Selection command sends the entire file content.

Commands

All commands are available in the Command Palette under the Send to Copilot CLI: prefix and in the editor right-click context menu.
