IntelliFix – AI-Powered Error Explanations and Fixes for VS Code

Demystify errors, learn faster, and fix code with confidence — right inside VS Code.

🧭 Introduction

IntelliFix is a professional-grade VS Code extension that helps developers understand, fix, and learn from code errors. When diagnostics occur, IntelliFix provides clear explanations, actionable fixes, and an interactive learning experience — turning debugging into a learning opportunity.

• AI-powered error explanations and automatic fixes for common issues
• Interactive "Learn from Error" walkthroughs to build understanding
• Inline error messages for fast feedback without breaking your flow

Supported languages: JavaScript, Python, C/C++, and Java.

✨ Core Features

1) 🛠️ AI‑Powered Code Fixes

Automatically analyze diagnostics and apply targeted fixes to your file.

• Uses editor diagnostics and LSP data to generate accurate corrections
• Returns corrected code plus explanations of what changed and why

2) 🎓 Interactive "Learn from Error"

A step‑by‑step, progressive guide that explains the error, shows how to resolve it, and provides the corrected solution.

• Focus a specific error or the error under the cursor
• Presents sections like Understanding the Error → How to Fix It → See the Solution → Learn More

3) 👁️ Inline Error Display (Error‑Lens style)

Surface diagnostics directly in the editor with severity-aware styling and optional actions.

• End‑of‑line messages, hover tooltips, and optional click-to-learn links
• Fully configurable: enable/disable severities, colors, and message placement

4) 🔍 Comprehensive Code Review

Go beyond syntax fixes with a full‑file analysis focused on quality, best practices, and maintainability.

• Highlights blocking issues, risky patterns, and potential bugs
• Suggests refactors, style and convention improvements, and clearer design choices
• Produces a structured report you can act on immediately
