BF apple-developer-toolkit
All-in-one Apple developer skill with three integrated tools shipped as a single unified binary. (1) Documentation search across Apple frameworks, symbols, and 1,267 WWDC sessions from 2014-2025. No credentials needed. (2) App Store Connect CLI with 120+ commands covering builds (find/wait/upload), TestFlight, pre-submission validate, submissions, signing, subscriptions (family-sharable), IAP, analytics, Xcode Cloud, metadata workflows, release pipeline dashboard, insights, win-back offers, promoted purchases, product pages, nominations, accessibility declarations, pre-orders, pricing filters, localizations update, diff, webhooks with local receiver, workflow automation, and more. Requires App Store Connect API key. (3) Multi-platform app builder (iOS/watchOS/tvOS/iPad/macOS/visionOS) that generates complete Swift/SwiftUI apps from natural language with auto-fix, simulator launch, interactive chat mode, and open-in-Xcode. Requires an LLM API key and Xcode. Includes 38 iOS development rules and 12 SwiftUI best practice guides for Liquid Glass, navigation, state management, and modern APIs. All three tools ship as one binary (appledev). USE WHEN: Apple API docs, App Store Connect management, WWDC lookup, or building iOS/watchOS/tvOS/macOS/visionOS apps from scratch. DON'T USE WHEN: non-Apple platforms or general coding.

How to improve
- Shorten the description to 1024 characters.
- The text references files that are not there: add them or drop the references.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

- 0Result and completion. Does not say what the result is
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 7 mutating operations with no state check
- 50When it triggers. No condition that starts the skill
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Steps. 5 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1944 tokens
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
