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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00181 | $0.01371 |
| Opus 5.5 | $0.00072 | $0.00548 |
| Sonnet 5.5 | $0.00036 | $0.00274 |
| Haiku 4.5 | $0.00018 | $0.00137 |
Grade A, and why
hig-inputs 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 1mo 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.
This is a copy
100% identical to hig-inputs — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Apple HIG: Inputs
Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.
Key Principles
-
Support multiple input methods. Touch, pointer, keyboard, pencil, voice, eyes, hands, controllers. Design for the inputs available on each platform. On iPadOS, support both touch and pointer; on macOS, both pointer and keyboard.
-
Consistent feedback for every input action. Visible, audible, or haptic response.
-
Standard gestures must behave consistently. Tap to activate, swipe to scroll/navigate, pinch to zoom, long press for context menus, drag to move. Don't override system gestures (edge swipes for back, Home, notifications).
-
Use standard recognizers; keep custom gestures discoverable. Apple's built-in recognizers handle edge cases and accessibility. If you add non-standard gestures, provide hints or coaching to teach them.
-
Apple Pencil: precision drawing, markup, and selection. Support pressure, tilt, and hover. Distinguish finger from Pencil when appropriate (finger pans, Pencil draws).
-
Support Scribble in text fields. Users expect to write with Pencil in any text input.
-
Keyboard shortcuts and full navigation. Standard shortcuts (Cmd+C/V/Z) plus custom ones visible in the iPadOS Command key overlay. Logical tab order.
-
Respect the software keyboard. Adjust layout when keyboard appears. Use keyboard-avoidance APIs.
-
Game controllers: MFi controllers with on-screen fallbacks. Map to extended gamepad profile, sensible defaults, remappable. Always offer touch or keyboard alternatives.
-
Pointer and trackpad: native feel. Hover effects, pointer shape adaptation, standard cursor behaviors. Two-finger scroll, pinch to zoom, swipe to navigate.
-
Digital Crown: primary scrolling and value-adjustment input on watchOS. Scrolling lists, adjusting values, navigating views. Haptic feedback at detents.
-
Eyes and spatial (visionOS): look and pinch. Generous hit targets (eye tracking is less precise than touch). Avoid sustained gaze for activation. Direct hand manipulation in immersive experiences.

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.

hig-inputs is a skill published in the GitHub repository chama-x/GroundRules (5 stars, last pushed 2mo ago), licensed MIT. It adds 181 tokens to every session and 1,371 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to hig-inputs, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
android-compose-patterns
Use when building native Android with Jetpack Compose - stateless composables, state hoisting, ViewModel-owned state, edge-to-edge, predictive back, adaptive layout, atomic components, and Material theming over hardcoded values.
mobile-design-system-foundation
Use when the mobile repository has no theme tokens or component library yet (a new app, an "Apply design system" task, or a task that asks for one), before building any screen - writes the approved design system's generated files from getdesignsystem (files true) and builds the theme from them when there is one.
mobile-ui-ux
Use when designing or building any mobile screen or component a user sees (Flutter, SwiftUI or Compose) - platform conventions, hierarchy, type that scales, colour roles and dark mode, safe areas and insets, forms and keyboard, states, feedback, and the generic-mobile anti-patterns.
mobile-accessibility
Use when building or changing any interactive mobile UI - VoiceOver/TalkBack labels, grouping, headings, focus order, Dynamic Type/font scale, reduce motion, contrast, and the automated check for each stack.
flutter-atomic-components
Use when adding or reusing Flutter UI - organize widgets as atoms, molecules, and organisms in a shared library and never hand-roll a component that already exists.
mobile-ui
Use when a ticket builds or reworks UI in a React Native / Expo (or React + Capacitor) mobile app and it must feel like a real, store-credible native app — not a wrapped mobile website. Covers the native-feel bar, safe areas and edge-to-edge, gestures and back navigation, haptics, Dynamic Type and screen readers…
