nithishchandra0119/ANGULAR-PROJECT ? reverse-engineered prompt

Build me a TypeScript package for Angular projects that checks code style and common mistakes with static analysis. I want it to work like a linter add on for Angular apps, so it can catch things like bad component and directive selectors, missing lifecycle interfaces, incorrect input and output patterns, unused CSS, and template issues.

Make it easy to plug into an existing Angular app with a simple config file, and also let people run it from the command line against one file or an entire project. Include a few example rules and a small demo showing the kind of errors it reports, plus clear setup instructions for Angular CLI and a custom TSLint setup. If it helps, look up current docs online for any Angular or TSLint details you need.
