Apple Documentation Router

Apple bundles for-LLM markdown documentation inside Xcode. These are authoritative, up-to-date guides and diagnostics written by Apple engineers. Use them alongside Axiom skills for the most accurate information.

When to Use

Use Apple's bundled docs when:

You need the exact API signature or behavior from Apple
Axiom skills reference an Apple framework and you want the official source
A Swift compiler diagnostic needs explanation
The user asks about a specific Apple framework feature

Priority: Axiom skills provide opinionated guidance (decision trees, anti-patterns, pressure scenarios). Apple docs provide authoritative API details. Use both together.
