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
via WebSearch or the product/competitive-analysis skill.
Optional ASC access to read the developer's existing portfolio (list_apps / get_metadata).
Flow
Internal check (your own portfolio).list_apps → for each shipped app read its positioning
(get_metadata). Does the candidate overlap one you already ship in function, code
template, or metadata? Two apps that differ only in theme/reskin = 4.3 risk.
External check (the market). Read VALIDATION.md if present; otherwise WebSearch for close
look-alikes. Judge: is the core function a thin reskin of an existing app, or a genuine wedge?
Distinctness scorecard. Score each dimension meaningful difference vs cosmetic, and flag any
that is only skin-deep:
Dimension
Distinct if…
Function
it does something materially different, not a template swap
Content / data
unique data or content, not a generic wrapper
Metadata
name / keywords / screenshots not near-identical to siblings or competitors
UX / value
a real reason a user picks this one
Verdict + remedy.
Distinct → proceed.
Borderline → give concrete ways to differentiate (merge sibling apps into one configurable
app, add the unique wedge, or drop it); if approved, name the specific wedge that MUST be built
to clear 4.3.
Duplicate → recommend not shipping; consolidate any existing thin apps into one strong
app instead.
Record. Write the verdict + reasoning to .planning/ (VALIDATION or STATE). For a
borderline-approved app, record the wedge as a build requirement so plan/build deliver it.
Done
A written verdict (distinct / borderline+wedge / duplicate) with per-dimension reasoning, and —
if borderline — the specific differentiation that must ship before submission.
Caveats
Cosmetic theming ≠ differentiation — Apple judges function + metadata similarity, not intent.
Protect the account. When in doubt between "borderline ship" and "consolidate," prefer one
strong app over several thin ones.
