Suggested MVP
A VS Code extension that scans all TypeScript/JavaScript files in the workspace and displays errors in the Problems panel, with basic filtering by file type and error severity. Include simple configuration for excluding node_modules and specifying file patterns to scan.
Distribution Strategy
Launch on VS Code Marketplace with freemium model (basic features free, advanced filtering/performance optimizations paid). Target TypeScript communities on Reddit, Discord, and Twitter, plus promote on the original GitHub issue thread.
