A small iPhone app experience that opens from a link, QR code, NFC tag, or other prompt without requiring a full App Store installation.

In plain words
What is it for?
Use it for tasks such as pay-at-table, scanning a merchant code, adding a card, or claiming an offer in a fintech app.
Why use it?

Token cost

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.

Security

Grade A, and why

app-clips 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 11d 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 — 259 lines — stays where its author put it; the contents beside it link to each section on GitHub.

App Clips (iOS)

A small, fast, launch-on-demand slice of your full app — invoked from a URL (NFC, QR, App Clip Code, Safari banner, Maps, Messages) without an App Store install. For a fintech app the common uses are pay-at-table, scan-to-pay a merchant code, onboard-a-card, or claim-an-offer, then hand off to the full app. Grounded in Apple's AppClip framework, StoreKit, and App Store Connect docs (iOS 26 era).

  • Deep links / associated domains: an App Clip is Universal-Links machinery narrowed to one target; see deep-linking.
  • Secure handoff: shared secrets go through an App Group container or CloudKit, not the Keychain (App Clip Keychain items are not readable by the full app) — see swift-security, cloudkit.
  • Writing physical tags: encode the invocation URL on an NDEF tag with core-nfc.
  • Purchases inside the clip: StoreKit works in a clip — see storekit; Apple Pay via passkit.
  • Submission gates: privacy manifest, size, entitlements — see app-store-review.

Contents

Architecture & targets

  • An App Clip is a separate target inside the full app's Xcode project (File ▸ New ▸ Target ▸ App Clip). It ships inside the full app's binary but downloads independently.
  • The App Clip bundle ID must be the full app's bundle ID plus one suffix segment: full app com.example.wallet → clip com.example.wallet.Clip.
  • One full app has exactly one App Clip. One App Clip can serve many experiences (many URLs / merchants).
  • Reuse code by putting shared logic in a framework or Swift package linked into both targets — do not duplicate. Keep the clip's slice minimal (see budget).
  • The clip is ephemeral: no background execution after the user leaves, data cleared if unused, capped lifetime. Design every flow to complete in one session or resume from the full app.

Changes

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.
