pp-apple-docs
Every Apple framework, indexed locally, with deprecation analysis and an MCP server no other Apple-docs tool has. Trigger phrases: `look up an Apple API`, `what's deprecated in iOS`, `find a SwiftUI symbol`, `port this from UIKit to SwiftUI`, `what changed at WWDC`, `use apple-docs`, `run apple-docs-pp-cli`.
Why this skill is useful
Adds executable commands for querying and analyzing Apple API documentation, enabling unique workflows for migration and deprecation analysis.

What this skill does
Apple Developer Documentation — Printing Press CLI Prerequisites: Install the CLI This skill drives the apple-docs-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: apple-docs-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Reach for this CLI when you need to read Apple's docs from a terminal, when an agent is grounding Swift code generation against current Apple APIs, when planning a platform migration (iPad → visionOS, AppKit → SwiftUI), or when authoring a 'what's deprecated in iOS N' guide. The local SQLite store unlocks queries — cross-framework grep, snapshot diff, deprecation cliff — that no online docs viewer offers. Anti-triggers Do not use this CLI for: Do not use this CLI to author Apple ID or App Store Connect API calls — use a separate App Store Connect CLI for those. Do not use this CLI as a Swift package manager — it reads docs, not source. Do not use this CLI to fetch full WWDC video transcripts — it indexes WWDC references from doc pages but does not host video content. Unique Capabilities These capabilities aren't available in any other tool for this API. Agent-native plumbing doc get — Project a 50KB+ DocC JSON page down to just the fields an agent actually needs — abstract, signature, platforms, or all three — saving context tokens on every lookup. …
How to use it
Reference it in AdaL, Claude Code, Cursor or any coding agent — nothing to install:
