replica-skill is the GitHub repo Jakeschincariol/replica-skill: eleven free Claude skills for reverse-engineering a public app’s flows, rebuilding a clean-room clone, testing it, then shipping under a new brand. The README states MIT, no signup, no API key, and nothing to connect. Credit line names Jake Schincariol / opusjake.ai.
The same README draws a hard line: rebuild what an app does (features and flows), not what it owns—source code, logos, trademarks, copy, private APIs, catalogues, or network effects. That boundary is repeated in the Fine print section and is the compliance frame for this article.
How to install replica-skill
Official install paths from the README:
Paste into Claude:
https://github.com/Jakeschincariol/replica-skill
install skill
As a Claude Code plugin:
/plugin marketplace add Jakeschincariol/replica-skill
/plugin install replica-skill@replica-skill
Plugin skills are namespaced (for example /replica-skill:replica-recon). For plain /replica-recon commands, clone and copy folders:
git clone https://github.com/Jakeschincariol/replica-skill.git
cp -r replica-skill/replica-* ~/.claude/skills/
Project-local install: copy the same replica-* folders into the repo’s .claude/skills/. Without Claude Code, paste any single SKILL.md at the top of a chat; Python helper tools will not run, but the method still applies. Tools need Python 3.8+ and use the standard library only—nothing to pip install.

The eleven skills and the pipeline
Repository top-level directories match the eleven skills named in the README:
| Command | Role (README wording) |
|---|---|
/replica-recon |
Reverse-engineer screens, flows, components, data model from public pages, screenshots, store listings, and your own account |
/replica-architect |
Plan stack, database schema, and API |
/replica-design |
Rebuild design system as tokens with your own assets |
/replica-build |
Rebuild the app screen by screen from the recon map |
/replica-backend |
Auth, database, payments, integrations |
/replica-test |
Click through flows and log bugs |
/replica-diff |
Parity score vs the original; list gaps |
/replica-entrepreneur |
Mine real user reviews for complaints → fixes and positioning |
/replica-brand |
New name and brand so the product is yours |
/replica-launch |
Landing page, pricing, store listing |
/replica-deploy |
Ship on your own domain |
Recommended order (README):
recon → architect → design → build → backend → test → diff → entrepreneur → brand → launch → deploy
Each step reads prior output under a project-local replica/ folder. You can also run a single skill alone—README calls out /replica-entrepreneur before committing to a full clone.
Helper scripts (standard-library Python, no network) include replica-diff/imgdiff.py, parity.py, replica-entrepreneur/reviews.py, replica-design/contrast.py, replica-brand/sweep.py, and replica-launch/listing.py. README says sweep.py blocks deploy until original names/domains/colours are gone from the codebase.
Compliance boundaries (README and LICENSE)
Facts as published by the project—not legal advice:
- Clean-room functionality only. Study public behaviour and UX patterns; write new code. Do not copy the target’s source, proprietary assets, logos, trademarks, copy, or private APIs.
- Only read what you are allowed to read. Public pages and your own account. No scraping behind logins against a site’s terms, no other people’s accounts, no paywall bypass. If your account terms forbid competitor research, README says the skills stick to public sources.
- Rebrand before launch. New name, palette, logo, words.
/replica-deployexpects a clean sweep. - “Clone any app” means features and flow, not owned content, networks, or licences (music catalogue example in README).
- No perfect-clone guarantee. Complexity varies; recon sizes the work; diff scores parity.
- Entrepreneur skill must not invent reviews. Quotes need links and stated sample size.
- Before you sell: run trademark checks listed by
/replica-brand, read third-party terms, consult a lawyer when money is on the line.
