Guideline-4.3 anti-spam / originality gate — score whether an app (and each portfolio addition) is meaningfully distinct in function, content, and metadata before you invest or submit. Use at validation/new-app time and again before submission. Protects the whole developer account from 4.3 (spam/duplicate) rejections. NOT rejection-handler (that works an existing rejection) and NOT competitive-analysis (that positions in the market).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Originality Check Decide, with evidence, whether an app is *distinct enough to exist* — before you build it or submit it. > At portfolio scale, shipping many similar small apps risks **Guideline 4.3 (spam / duplicate)** > — this is the go/no-go distinctness gate that keeps that from happening. ## Where it fits (read the seams) - **Not `rejection-handler`.** That works a rejection you *already have*. This is upstream — it prevents the 4.3 by catching sameness before you ship. - **Not `competitive-analysis` / `market-research`.** Those size demand and position you in the market. This judges *distinctness* (function + content + metadata) vs your own portfolio and vs near-identical competitors — a spam risk, not a demand question. - **Two moments to run it:** at `validate` / `new-app` (don't build a dup) and before `submit` (don't trip 4.3). Also periodically across the portfolio (internal cannibalization / template-sameness). ## Prerequisites - The app idea or a shipped app to evaluate (name, one-line function, target metadata). - Optional: `.planning/VALIDATION.md` (competitor + market data). If missing/stale, gather fresh …

How to install
mdr add rshankras/claude-code-apple-skills/originality-check@sha256:bfd007edc914509dThe line at the top of this page pins the label git:20260716.1361023, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
