C/Code is an AI pair-programming assistant that lives right inside VS Code — one keystroke opens a live session in a split terminal, aware of whatever file or selection you're looking at.
Prerequisites
Requires a local CLI runtime already available on your machine. C/Code takes care of launching and talking to it — you shouldn't need to think about it day to day.
Features
Quick Launch: Use Cmd+Esc (Mac) or Ctrl+Esc (Windows/Linux) to open a C/Code terminal in a split view, or focus an existing session if one's already running.
New Session: Use Cmd+Shift+Esc (Mac) or Ctrl+Shift+Esc (Windows/Linux) to start a fresh C/Code session, even with one already open. The C/Code button in the editor toolbar does the same.
Context Awareness: Your current selection or open file is shared with the session automatically.
File Reference Shortcuts: Use Cmd+Option+K (Mac) or Alt+Ctrl+K (Linux/Windows) to insert a reference to the active file, e.g. @File#L37-42.
Pre-release builds
C/Code ships on two Marketplace channels. Pre-release versions (0.9.x) carry
changes still under test, and you receive them only if you opt in - everyone
else stays on the stable line.
Open the Extensions view and search for C/Code.
Click the dropdown next to Install and choose Install Pre-Release
Version. On an already-installed copy, use Switch to Pre-Release
Version.
VS Code then auto-updates you to each new pre-release build.
Switch to Release Version in the same menu moves you back to the stable
line.
Development
code sdks/vscode - Open the sdks/vscode directory in VS Code. Do not open from repo root.
bun install - Run inside the sdks/vscode directory.
Press F5 to start debugging - This launches a new VS Code window with the extension loaded.
Making Changes
tsc and esbuild watchers run automatically during debugging (visible in the Terminal tab). Changes to the extension are automatically rebuilt in the background.
To test your changes:
In the debug VS Code window, press Cmd+Shift+P
Search for Developer: Reload Window
Reload to see your changes without restarting the debug session
