Disk Octopus: AI-Powered Terminal Storage Analytics Built with GitHub Copilot CLI

GitHub Copilot CLI Challenge Submission

This is a submission for the GitHub Copilot CLI Challenge

What I Built

Disk Octopus - Intelligent Storage Analytics powered by AI

I built a professional-grade terminal application that transforms how users analyze and understand their disk storage. Disk Octopus combines sophisticated file system visualization with AI-powered analysis to provide deep insights into storage usage patterns.

Key Features Built:

πŸ–₯️ Interactive Terminal UI

  • Split-panel interface with resizable sections using Textual framework
  • Beautiful braille octopus ASCII art for visual appeal
  • Real-time file tree with intelligent lazy-loading
  • Status bar with progress tracking

πŸ“Š Advanced File Analysis

  • Recognition and categorization of 40+ file types (code, documents, media, config, specialized formats)
  • Real-time file type statistics and storage distribution analysis
  • File path indexing and searchable results
  • Intelligent file complexity classification

πŸ€– AI-Powered Deep Analysis

  • Integration with GitHub Copilot CLI for enhanced file analysis
  • Intelligent fallback analyzer using pattern-based analysis when Copilot unavailable
  • Analysis of file purpose, usage context, creator information, and practical assessments
  • Support for files up to 5MB with streaming analysis

⚑ Performance Optimizations

  • Lazy-loading of directory trees for instant responsiveness
  • Intelligent caching of analysis results
  • Efficient terminal rendering with minimal CPU usage
  • Async file scanning with real-time progress

Technical Architecture:

  • Core: Python 3.10+ with Textual TUI framework
  • UI: Rich terminal formatting with CSS-based styling
  • Analysis: Pattern-based intelligent analyzer + Copilot CLI integration
  • File System: Recursive directory scanning with size tracking
  • Data Processing: Real-time statistics aggregation

Why I Built This:

Traditional disk analysis tools like WizTree are GUI-only and resource-intensive. Disk Octopus brings powerful storage analytics directly to the terminal - where developers work. The AI integration transforms generic file analysis into actionable insights about file purposes, storage patterns, and disk organization opportunities.

My Experience with GitHub Copilot CLI

How I Used Copilot CLI:

1. Deep File Analysis Integration
I integrated GitHub Copilot CLI to analyze file contents and generate intelligent commentary. The challenge was that subprocess calls with complex prompts would hang on Windows. I solved this by implementing an intelligent fallback analyzer that uses pattern-based analysis, while still leveraging Copilot when available.

2. Problem-Solving for Complex Issues
When deep analysis wasn't working (files showing "Uploading... Please Wait" indefinitely), I used Copilot to help debug the subprocess hanging issue. This led me to discover PowerShell argument parsing limitations and implement a robust fallback mechanism.

3. Development Acceleration
Copilot CLI helped me:

  • Generate analysis frameworks for file categorization
  • Create intelligent fallback logic for when Copilot is unavailable
  • Develop comprehensive file type recognition across 40+ formats
  • Debug threading and async issues with terminal UI updates

Impact on Development Experience:

Positive Impacts:

  • βœ… Reduced debugging time for complex subprocess issues
  • βœ… Accelerated implementation of file type detection system
  • βœ… Helped design the intelligent fallback analyzer architecture
  • βœ… Provided pattern suggestions for file analysis frameworks
  • βœ… Enhanced code quality through intelligent suggestions

Technical Achievements:

  • Built a production-ready terminal application with advanced features
  • Implemented robust error handling and fallback mechanisms
  • Created 40+ file type recognition system
  • Achieved seamless Copilot integration with graceful degradation
  • Delivered comprehensive documentation and user guides

Key Learning:
The biggest insight was designing systems that gracefully degrade when external services (like Copilot CLI) are unavailable. This approach made the application more robust and user-friendly, as it works perfectly even without Copilot while providing enhanced features when available.

Copilot CLI Integration Details:

The application automatically:

  1. Detects if Copilot CLI is installed
  2. Attempts analysis via Copilot when available
  3. Falls back to intelligent pattern-based analysis if not
  4. Shows users which analysis method was used
  5. Provides meaningful insights either way

This design philosophy made Disk Octopus inclusive for all users, regardless of their GitHub Copilot subscription status.

Project Highlights

  • Professional Quality: Production-ready code with clean architecture
  • Cross-Platform: Works on Windows, macOS, and Linux
  • Well-Documented: Comprehensive README with screenshots and setup guides
  • User-Friendly: Intuitive keyboard navigation and clear help system
  • Open Source: MIT licensed, ready for community contributions
  • Robust: Handles large directories and files gracefully

Version: 1.0.0
