🚀 Gemini AI Code Companion (Dev Refactor AI)

Next-generation, commercial-grade AI pair programmer directly integrated into Visual Studio Code.
Powered by the lightning-fast Google Gemini Flash API, offering seamless real-time completions, inline cursor edits, security auditing, split diff reviews, and smart devops workflows.

🌟 Key Features Showcase

1. ⚡ Ghost-Text Inline Autocomplete

• Low-latency GitHub Copilot-style inline code suggestions in gray text as you type.
• Accept suggestions instantly with Tab or toggle suggestions on/off using Alt + \.

2. 💬 Interactive Sidebar Chat Assistant

• Sleek glassmorphism UI embedded in the VS Code Activity Bar.
• One-click action triggers: Fix & Refactor, Explain Code, and custom conversational debugging.

3. ✍️ Comment-to-Code Generation

• Simply write a comment (e.g. // function to find factorial of a number) and watch Gemini synthesize idiomatic, fully functional implementations automatically.

4. 🎯 Floating Inline Edit (Ctrl + I)

• Select any block of code and press Ctrl + I to trigger an in-place floating input.
• Prompt natural language instructions (e.g., "Convert to async/await", "Add input validation") without leaving the editor canvas.

5. 🔀 Native Split Diff Viewer

• Review all AI-generated code transformations side-by-side (Original ↔ Gemini Edit) before committing changes to your workspace.

6. 🛠️ Terminal Error Auto-Fixer

• Automatically diagnose complex shell, runtime, or package manager errors (such as npm ERR! ERESOLVE).
• Provides instant root-cause breakdowns and ready-to-run copyable terminal commands.

7. ✨ AI Git Commit Message Generator

• Directly integrated into the VS Code Source Control panel title bar (✨ icon).
• Automatically reads staged changes (git diff --cached) and crafts conventional semantic commit messages (e.g., feat: ..., fix: ...).

8. 🛡️ Real-Time Security & Secret Scanner

• Audits files on save for exposed credentials, Google API keys, database connection strings, JWT tokens, and SSH keys.
• Flags vulnerabilities inline with diagnostic underlines and provides mitigation advice via the Problems panel.

9. 🔍 Smart Hover Tooltip Provider

• Hover over complex syntax—such as regular expressions—to view inline interactive markdown cards breaking down pattern logic.

10. 🏗️ Automated Boilerplates, JSDoc & Unit Tests

• Scaffolding: QuickPick templates for production Express REST servers, multi-stage Dockerfiles, Mongoose schemas, and Tailwind templates.
• JSDoc Injection: Auto-generate complete docstrings with @param and @returns tags.
• Unit Test Suite: Auto-generate isolated test cases utilizing native assert or Jest frameworks.
