A Bug Finder CLI to explore your application bugs

GitHub Copilot CLI Challenge Submission

This is a submission for the GitHub Copilot CLI Challenge

What I Built

I built a Bug Finder CLI tool powered by the GitHub Copilot SDK. The tool analyzes a bug ticket, reasons about it, and scans the codebase to identify likely root causes and relevant files.

This project was inspired by a real problem at work: tracking a reported bug across a large codebase often takes hours. Understanding the context, tracing dependencies, and identifying potential breakpoints is time-consuming and mentally expensive.

This tool performs the preliminary investigation automatically. It:

  • Interprets the bug ticket
  • Searches the repository for related code paths
  • Highlights potential problem areas
  • Suggests next debugging steps

Instead of starting from scratch, I begin with structured insights. It reduces investigation time and lets me focus on solving the problem rather than locating it.

My Experience with GitHub Copilot CLI

As a full-time software engineer, I have limited time for side projects. To make this feasible, I set up GitHub Copilot CLI on my home Raspberry Pi and built the entire application using it.

The CLI-based workflow fit perfectly with how I work. I would:

  • Prompt Copilot to implement or refactor features
  • Let it generate code
  • Review, test, and iterate

Features like plan mode, diff view, code review, and model reasoning control significantly improved productivity.

The experience was strong overall, but a few improvements would make it even better:

  • An “undo last prompt” feature
  • Faster navigation between previous prompts

Despite that, Copilot CLI dramatically reduced the friction of building and experimenting.
