Rubber Duck Copilot
Rubber Duck Copilot is a playful debugging companion. When you save a file or hit errors, it asks a thoughtful question to help you reason out loud.
What it does
- Picks short, curated prompts across understanding, assumptions, boundaries, observability, and clarity.
- Avoids repeating the same prompt twice in a row.
- Includes cooldowns, session caps, and a 10-minute mute.
- Includes a Duck Panel in the sidebar with a cute duck and quick actions.
- Prompts and UI labels follow your VS Code display language (English/Spanish).
Development
From the repo root:
cd extensions/rubber-duck-copilot
