Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00095 | $0.01003 |
| Opus 5 | $0.00048 | $0.00502 |
| Sonnet 5 | $0.00019 | $0.00201 |
| Haiku 4.5 | $0.00010 | $0.00100 |
Grade A, and why
originality-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 beforesubmit(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 theproduct/competitive-analysisskill. - 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.mdif present; otherwiseWebSearchfor 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
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

originality-check is a skill published in the GitHub repository rshankras/claude-code-apple-skills (713 stars, last pushed 1mo ago), licensed MIT. It adds 95 tokens to every session and 1,003 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
