4 use cases

  • Scope an app clone before you build it

    Map an app's screens and flows, then check what its users complain about.

    View prompt
    Using the replica-skill repo (github.com/Jakeschincariol/replica-skill), run the replica-recon and replica-entrepreneur skills on <target app URL>. Expected output: replica/recon.md listing screens, flows, components, and out-of-scope items, plus a complaint summary. Verify that every complaint in the summary links to a source.

  • Score a rebuilt clone against the original app

    Get a layout diff and a parity score for your clone.

    View prompt
    Using the replica-skill repo (github.com/Jakeschincariol/replica-skill), compare <original.png> with <clone.png> using imgdiff.py and score <replica/features.csv> with parity.py. Expected output: diff.png and a parity score with a missing list. Verify that the missing list includes every must-have that is not done.

  • Rank the complaints users have about an app

    Turn a CSV of linked reviews into ranked, sourced complaint themes.

    View prompt
    Using the replica-skill repo (github.com/Jakeschincariol/replica-skill), run reviews.py on <replica/reviews.csv>. Expected output: ranked complaint themes with linked quotes. Verify that every quote printed matches a row in the input file and carries that row's URL.

  • Check a rebranded clone before you launch it

    Sweep the code for leftover original names and lint the store listing.

    View prompt
    Using the replica-skill repo (github.com/Jakeschincariol/replica-skill), run sweep.py on <project root> avoiding <Original App name> and listing.py on <replica/launch/listing.json>. Expected output: a sweep report and a listing report. Verify that the sweep finds no original name, domain, or colour, including inside identifiers.
