A guide for adding vibration and other tactile signals to iOS interactions. It covers standard feedback for taps, selections, success, warnings, and errors, plus custom patterns with Core Haptics.

Use it when adding tactile feedback to buttons, pickers, completed actions, warnings, failures, or custom interaction patterns in an iOS app.

It helps users understand actions through touch, especially when a visual change alone may be easy to miss. It also explains how to avoid using haptics on devices that do not support them.

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.

Model	Per session	Once invoked
Fable 5	$0.00030	$0.00444
Opus 5	$0.00015	$0.00222
Sonnet 5	$0.00006	$0.00089
Haiku 4.5	$0.00003	$0.00044

Security

Grade A, and why

haptics 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 2d 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.

What it actually says

Haptic Feedback

Use this guide when adding tactile feedback to interactions.

Quick Reference

Impact Feedback (taps, collisions)

UIImpactFeedbackGenerator(style: .medium).impactOccurred()

Styles: .light, .medium, .heavy, .soft, .rigid

Notification Feedback (outcomes)

UINotificationFeedbackGenerator().notificationOccurred(.success)

Types: .success, .warning, .error

Selection Feedback (picker changes)

UISelectionFeedbackGenerator().selectionChanged()

Best Practices

Call generator.prepare() before use for lower latency
Check hardware support: CHHapticEngine.capabilitiesForHardware().supportsHaptics
Use .light for subtle confirmations, .medium for standard taps, .heavy for emphasis
Use .success for completed actions, .warning for caution, .error for failures

CoreHaptics (Custom Patterns)

import CoreHaptics

let engine = try CHHapticEngine()
try engine.start()

let event = CHHapticEvent(
    eventType: .hapticTransient,
    parameters: [
        CHHapticEventParameter(parameterID: .hapticIntensity, value: 0.8),
        CHHapticEventParameter(parameterID: .hapticSharpness, value: 0.5)
    ],
    relativeTime: 0
)

let pattern = try CHHapticPattern(events: [event], parameters: [])
let player = try engine.makePlayer(with: pattern)
try player.start(atTime: 0)

When to Use

Action	Haptic
Button tap	`.light` impact
Toggle switch	Selection changed
Delete action	`.warning` notification
Save success	`.success` notification
Slider snap	Selection changed
Error state	`.error` notification

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.

haptics is a skill published in the GitHub repository moasq/ios-dev-agent (4 stars, last pushed 3mo ago), licensed MIT. It adds 30 tokens to every session and 444 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

orca-emulator-android

Control an Android emulator / device from inside Orca using the orca CLI. Use for listing/booting AVDs, taps, swipes, typing, hardware buttons (incl. Back and Recents), rotation, app install/launch, runtime permissions, the accessibility tree, and logcat — driving a real adb-connected device or emulator.…
