The Ultimate LeetCode-to-GitHub Automation Engine

AlgoVault is a production-grade Chrome extension designed for software engineers who want to automate their coding journey. It seamlessly synchronizes your LeetCode submissions to a dedicated GitHub repository, creating a professionally structured portfolio of your problem-solving skills.

Unlike basic sync tools, AlgoVault is built with a "Nuclear Stability" architecture, ensuring it remains resilient during browser updates, extension reloads, and complex page lifecycles.

• ⚡ Instant Auto-Sync: Automatically pushes your "Accepted" submissions to GitHub within 1 second.
• 🛡️ Nuclear Stability: Hardened against "Extension context invalidated" errors using advanced zombie-state detection and defensive API wrappers.
• 📁 Professional Structuring: Organizes your code by Topic > Problem Name > Language > solution.ext.
• 📊 Real-time Dashboard: Automatically generates and updates a recruiter-friendly README.md in your repository root with activity heatmaps and categorized problem lists.
• 🔐 Secure & Private: Uses GitHub Device Flow for authentication. Your tokens are encrypted and stored locally on your device.
• 🤖 Intelligence: (Optional) Integrated with OpenRouter for intelligent problem analysis and complexity categorization.

• Core: TypeScript, React, Vite
• Storage: IndexedDB (for high-volume history), chrome.storage.local (for state)
• Manifest: Version 3 (MV3) compliant
• Styling: Material Design 3 inspired aesthetics with Vanilla CSS/Tailwind
• Communication: Robust background-to-content script messaging with auto-recovery

AlgoVault is built to handle the "Edge Cases" that break other extensions:

• Zero Duplicates: Strict synchronous locking prevents duplicate commits even during rapid page refreshes.
• Context Awareness: Proactively detects when the extension has been updated and prompts the user to refresh, preventing silent failures.
• Atomic Operations: Uses a job queue system with exponential backoff to ensure no submission is ever lost due to network issues.
