axiom-apple-docs is a skill for Claude Code, Codex from ComeOnOliver/skillshub. It costs 54 tokens per session (1,629 once invoked), scanned A, original, MIT.

A guide for answering questions about Apple frameworks, APIs, Swift compiler errors, and documentation included with Xcode. It serves as a route to Apple’s official technical material.

In plain words
What is it for?
Use it to look up API behavior and signatures, investigate Swift errors, and supplement architecture guidance with Apple’s own documentation.
Why use it?
It helps developers find accurate details about current Apple APIs and understand compiler diagnostics instead of relying on guesses or outdated examples.

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

axiom-apple-docs 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 6d 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 — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

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.
