What it does

Storekit is an agent skill from dpearson2699/swift-ios-skills. Implement, review, or improve in-app purchases and subscriptions using StoreKit 2. Use when building paywalls with SubscriptionStoreView or ProductView, processing transactions with Product and Transaction APIs, verifying entitlements, handling purchase flows (consumable, non-consumable, auto-renewable), implementing offer codes or promotional/win-back/introductory offers, managing subscription status and renewal state, setting up StoreKit testing with configuration files, or integrating Family Sharing, Ask to…

Its SKILL.md is about 4.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `evals/evals.json`, `references/app-review-guidelines.md` and `references/storekit-advanced.md`).

It sits in Mobile, covering iOS development, Error handling and Referral and retention marketing. It works with SwiftUI and iOS. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.

When your agent uses it

  • Building paywalls with SubscriptionStoreView
  • Processing transactions with Product and Transaction APIs
  • Verifying entitlements
  • Handling purchase flows (consumable

Example prompts

  • “/storekit”

Workflow steps

10 steps, taken from the step headings in SKILL.md.

  1. Not starting Transaction.updates at app launch
  2. Forgetting transaction.finish()
  3. Ignoring verification result
  4. Using original In-App Purchase APIs in new StoreKit 2 code
  5. Not checking revocationDate
  6. Hardcoding prices
  7. Not handling .pending purchase result
  8. Checking entitlements only once at launch
  9. Missing restore purchases button
  10. Subscription views without policy links

What it can do on your machine

Read from SKILL.md and the folder at commit 8d90fd1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • sosumi.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Storekit loads about 4.3k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 143 tokens; SKILL.md has 696 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~143
When it runs · the whole SKILL.md, loaded when a task matches
~4.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~11k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 696 words (~4,293 tokens).

“Implement in-app purchases, subscriptions, paywalls, and StoreKit testing using StoreKit 2. Use the modern Swift-based Product, Transaction, PurchaseAction, StoreView, and SubscriptionStoreView APIs. Avoid original In-App Purchase APIs (SKProduct, SKPaymentQueue) unless legacy OS support requires them.”
