Prompt

typescript-package-manager Create a mock documentation site for a
TypeScript tool that has variations for several package managers.
The site will be hosted on GitHub Pages, so - use development tools
and no production elements. The TypeScript tool will compare files in
regards to file size, date created, and date modified; and will be
able to check local and remote files. With one condition - by default
the files must have the same file name, else utilize a specific
option for when comparing files with different names.

In addition to making the mock documentation site, create a smoke and
mirror demo where core functionality of the tool can be tested. Use a
form that will not write to a file, but simulate updating local and
remote files.

Break this into two prompts.

Results

Good.
