Openducky

Rubber duck debugging quiz plugin for OpenCode.

Test your understanding of code through interactive quizzes - the AI reads a file and quizzes you on it, one question at a time.

Installation

Add to your opencode.json:

{
  "plugin": ["openducky"]
}

Usage

Just ask to be quizzed on any file:

ducky

Quiz me on src/index.ts

Use ducky to test my understanding of the auth module

OpenCode will prompt you to select a file and quiz mode, then begin the interactive quiz.

Quiz Flow

1. Select a file - Choose which file you want to be quizzed on
2. Choose a mode - Skim (high-level) or Full (implementation details)
3. Answer questions - 3-5 questions presented one at a time
4. Get feedback - Each answer is evaluated with corrections if needed
5. Review summary - Final assessment of your understanding

Modes

Mode	Focus
Skim	Purpose, architecture, exports, interfaces, what the code does overall
Full	Logic flow, edge cases, error handling, why specific decisions were made

Topic Focus (Optional)

Narrow the quiz to a specific aspect:

Quiz me on src/api.ts, focus on error handling

Test my understanding of the caching logic in utils.ts
