Replica Diff, score how close your clone is to the original
Compares an app clone against the original: a feature parity score from the feature matrix, plus a screenshot layout diff that ignores colour so a rebrand does not count against you.
- What
- Compares an app clone against the original: a feature parity score from the feature matrix, plus a screenshot layout diff that ignores colour so a rebrand does not count against you.
- Cost
- Free
- Needs
- a current feature matrix (replica/features.csv) and paired screenshots of the original and the clone in the same viewport and state; Python 3 for the tools (standard-library only, no installs).
- Install
- Copy the installer prompt below into your Muse — your agent does the rest.
Curated by Skill Harbor: the comparison step of the 11-skill Replica pack. Replica Diff answers how close your clone really is: a weighted feature parity score from your feature matrix, with the missing list in build order, a screenshot layout diff that ignores colour so a rebrand does not count against you, and a behaviour diff walked flow by flow. The report ends with an honest verdict: not shippable if any must-have is missing or an S1 bug is open, shippable when the must-haves are done and the feature score reaches 80 (the --visual overall score is a different number: 80% features + 20% layout), or better than the original when the entrepreneur fixes are in too.

Install
Copy the install package below, then paste it into Muse📌 Pinned version: commit 77c9436Prerequisites: a current feature matrix (replica/features.csv) and paired screenshots of the original and the clone in the same viewport and state; Python 3 for the tools (standard-library only, no installs). Install "Replica Diff, score how close your clone is to the original" for me. It gives my agent @Jakeschincariol's comparison workflow, the comparison step of the Replica pack: a weighted feature parity score with the missing list in build order, a screenshot layout diff that ignores colour so a rebrand does not count against you, a behaviour diff flow by flow, and an honest verdict: not shippable, shippable, or better than the original. Repository: https://raw.githubusercontent.com/Jakeschincariol/replica-skill/77c9436fb3d18c3d58169efb8caf4fe906b0dc51/replica-diff/SKILL.md Pinned version: install the code at commit 77c9436fb3d18c3d58169efb8caf4fe906b0dc51 exactly. Do not substitute a newer version. If this commit is unreachable, stop and tell me. 1. Fetch the SKILL.md file (and any helper files, including parity.py and imgdiff.py) from the repository path into a temporary folder 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code: you create your own accounts and keys and put keys in .env.local, the agent writes .env.example with names only and never types a password, card or live key. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "replica-diff". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. bring the feature matrix up to date; take paired screenshots in the same viewport and state). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. In Muse, invoke pack neighbour skills by name, not as /slash commands. If anything looks off, stop and ask me. After installation, ask me if I want to leave private feedback Private for now: only the Skill Harbor team sees it. Sellers may be looped in later.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
