Your rubber duck finally has opinions — detect code smells, get roasted with sarcastic inline annotations.
Inspired by CS50's rubber duck debugging, but this duck fights back.
Features
- Inline roast comments — sarcastic one-liners appear as italic annotations next to problematic lines, color-coded by severity (mild/medium/spicy)
- Two roast engines — free template-based roasts or AI-generated roasts via the VS Code Language Model API (requires Copilot or similar)
- Regex scanner — catches TODO/HACK comments, empty catch blocks, commented-out code, console.log spam, hardcoded secrets, long functions, and repeated magic strings
- Diagnostic scanner — picks up compiler errors, type errors, unused variables, deprecated APIs, lint violations, and more from any language server
- Auto-roast — triggers on file save, file switch, and diagnostic updates
Supported Languages
TypeScript, JavaScript, TSX, JSX, Python, Go, Rust, Java, C#, C++.
The diagnostic scanner works with any language that has a VS Code language server.
