vercel-labs/zero — reverse-engineered prompt

Build me an experimental programming language project called Zero, aimed at helping agents create small native tools.

I want a working compiler command line tool that can check, run, and build simple Zero source files, with clear output and predictable behavior. Include example programs so someone can try hello world, basic math, small systems style packages, web route examples, and size or graph inspection commands. Add a local documentation site with getting started, a practical language tour, language reference, and examples grouped by concept.

Please include tests for the CLI and language behavior, conformance fixtures, native compiler tests, benchmarks, and a simple way to validate everything with npm scripts. It should also have a VS Code extension for syntax highlighting of .0 files. Keep the language clearly marked as experimental, with docs explaining that the compiler, standard library, and syntax may still change.

Look up current docs online if you need to, and make the repo easy for someone to install, run locally, and give feedback on.
