axiom-extensions-widgets-ref is a skill for Claude Code, Codex from ComeOnOliver/skillshub. It costs 46 tokens per session (9,263 once invoked), scanned A, original, MIT.

An API reference for Apple's iOS widget and app-extension systems, including WidgetKit, ActivityKit, App Groups, and extension lifecycle rules. It covers standard and interactive widgets, Live Activities, Control Center controls, and visionOS widgets.

In plain words
What is it for?
Use it to implement widgets, Live Activities, Control Center controls, shared app data, widget refresh policies, or extension integrations with App Intents.
Why use it?
It gives developers the relevant platform details when they need to build system-facing app extensions or understand how their timelines, permissions, and shared data work.

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-extensions-widgets-ref 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 9d 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.

Extensions & Widgets API Reference

Overview

This skill provides comprehensive API reference for Apple's widget and extension ecosystem:

  • Standard Widgets (iOS 14+) — Home Screen, Lock Screen, StandBy widgets
  • Interactive Widgets (iOS 17+) — Buttons and toggles with App Intents
  • Live Activities (iOS 16.1+) — Real-time updates on Lock Screen and Dynamic Island
  • Control Center Widgets (iOS 18+) — System-wide quick controls
  • Liquid Glass Widgets (iOS 26+) — Accented rendering, glass effects, container backgrounds
  • visionOS Widgets (visionOS 2+) — Mounting styles, textures, proximity awareness
  • App Extensions — Shared data, lifecycle, entitlements

Widgets are SwiftUI archived snapshots rendered on a timeline by the system. Extensions are sandboxed executables bundled with your app.

When to Use This Skill

Use this skill when:

  • Implementing any type of widget (Home Screen, Lock Screen, StandBy)
  • Creating Live Activities for ongoing events
  • Building Control Center controls
  • Sharing data between app and extensions
  • Understanding widget timelines and refresh policies
  • Integrating widgets with App Intents
  • Adopting Liquid Glass rendering in widgets
  • Supporting watchOS or visionOS widgets
  • Implementing visionOS mounting styles, textures, or proximity awareness

Do NOT use this skill for:

  • Pure App Intents questions (use app-intents-ref skill)
  • SwiftUI layout issues (use swiftui-layout skill)
  • Performance optimization (use swiftui-performance skill)
  • Debugging crashes (use xcode-debugging skill)
  • app-intents-ref — App Intents for interactive widgets and configuration
  • swift-concurrency — Async/await patterns for widget data loading
  • swiftui-performance — Optimizing widget rendering
  • swiftui-layout — Complex widget layouts
  • extensions-widgets — Discipline skill with anti-patterns and debugging

Key Terminology

  • Timeline — Series of entries defining when/what content to display; system shows entries at specified times
  • TimelineProvider — Protocol supplying timeline entries (placeholder, snapshot, timeline generation)
  • TimelineEntry — Struct with widget data + display date
  • Timeline Budget — Daily limit (40-70) for timeline reloads
  • Budget-Exempt — Reloads that don't count (user-initiated, app foregrounding, system-initiated)
  • Widget Family — Size/shape (systemSmall, systemMedium, accessoryCircular, etc.)
  • App Groups — Entitlement for shared data container between app and extensions
  • ActivityAttributes — Static data (set once) + dynamic ContentState (updated during lifecycle)
  • ContentState — Changing part of ActivityAttributes; must be under 4KB total
  • Dynamic Island — iPhone 14 Pro+ Live Activity display; compact, minimal, and expanded sizes
  • ControlWidget — iOS 18+ widgets for Control Center, Lock Screen, and Action Button
  • Supplemental Activity Families — Enables Live Activities on Apple Watch or CarPlay

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.
