SDD — VS Code Extension

Control the SDD coding agent directly from VS Code. Run autonomous coding sessions, chat with @sdd in VS Code Chat, and monitor your agent from a sidebar dashboard — all without leaving the editor.

Requirements

SDD must be installed before activating this extension:

npm install -g sdd-pi

Node.js ≥ 20.0.0 and Git are required.

Features

Click the SDD icon in the Activity Bar to open the agent dashboard. It shows:

Connection status (connected / disconnected)
Active model and provider
Thinking level
Token usage and session cost
Quick action buttons: Start, Stop, New Session, Compact, Abort

Chat Integration (`@sdd`)

Use @sdd in VS Code Chat (Ctrl+Shift+I) to send messages to the agent:

@sdd refactor the auth module to use JWT
@sdd /sdd auto
@sdd what's the current milestone status?
