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
