Building a Production CLI Tool to Gamify and Enforce Code Documentation with GitHub Copilot CLI

This is a submission for the GitHub Copilot CLI Challenge What I Built Cognitive Guard - A CLI tool that analyzes code complexity and blocks commits when complex functions lack documentation. It uses cognitive complexity (not just lines of code) and adds gamification to make documentation less painful. 🔗 GitHub : cognitive-guard 📦 PyPI : pip install cognitive-guard Core Features Analyzes cognitive complexity using AST parsing Blocks git commits with undocumented complex code Interactive TUI for fixing violations in-terminal Achievement system with progress tracking Multi-language support (Python, JS, TS) Demo # Quick demo cognitive-guard demo # Interactive setup cognitive-guard init --interactive # When you try to commit undocumented code: git commit -m "Add feature" 🔍 Analyzing staged files... 🚫 COMMIT BLOCKED Found 2 violations: 📁 src/utils.py ❌ calculate_discount ( complexity: 15 ) - Missing docstring # Progress tracking cognitive-guard stats 📊 Your Documentation Journey Current: ██
