ApKI — Apple Knowledge Index

ApKI is a compact routing skill for current, official Apple developer resources. It indexes Apple Developer videos, framework documentation, Swift, Human Interface Guidelines, sample code, technology overviews, Apple Open Source, and curated Apple/SwiftLang open-source repositories without copying the underlying documentation into the skill.

Installing ApKI

Install the skill with npx:

npx skills add https://github.com/Gucky/ApKI --skill apki

To install it globally for Codex:

npx skills add https://github.com/Gucky/ApKI --skill apki --agent codex --global

For a specific agent:

npx skills add https://github.com/Gucky/ApKI --skill apki --agent claude-code

For all supported agents:

npx skills add https://github.com/Gucky/ApKI --skill apki --agent '*'

If npx is not available, install Node.js first. On macOS with Homebrew:

brew install node

Using ApKI

Invoke the skill directly:

$apki

Or ask naturally, for example: “Find the official Apple documentation and WWDC sessions for AsyncImage, StoreKit subscriptions, or App Intents.”

ApKI provides:

• a complete Apple Developer video catalogue;
• a directory of Apple frameworks and technologies;
• focused component indexes for common Apple-platform development tasks;
• curated Apple and SwiftLang libraries, developer tooling, toolchain references, and evolution resources;
• direct routes to HIG, sample code, technology overviews, and Apple Open Source.

Requirements

• Node.js for npx
• An AI coding assistant that supports agent skills
• Internet access for following Apple source links
