What it does
Game Feel is an agent skill from rshankras/claude-code-apple-skills. Game feel ("juice") for Apple apps — celebration choreography, haptic vocabulary design, sound-effect layers, and the event×channel feedback audit. Use when big moments fall flat, when designing haptics or SFX, or when auditing whether every meaningful event actually reaches the user.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `feedback-audit.md`, `haptic-design.md` and `sound-design.md`).
It sits in Media & Creative, covering Music and audio generation. The repository describes itself as: Claude Code skills for Apple platform development (iOS, macOS, iPadOS) — product validation, code generation, App Store optimization, and more. The licence is MIT.
When your agent uses it
- Big moments fall flat
- Designing haptics
- Auditing whether every meaningful event actually reaches the user
Example prompts
- “/game-feel”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 9ffb831. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
developer.apple.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Game Feel loads about 1.6k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 630 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Game Feel (Juice)
Makes an app's meaningful moments land — through coordinated motion, haptics, and sound. Animation technique lives in design/animation-patterns; confetti/badge generation lives in generators/milestone-celebration. This skill is the discipline layer: which events deserve feedback, on which channels, and how to verify nothing important is silent.
When This Skill Activates
Use this skill when the user:
- Says the app feels flat, lifeless, or "lacks juice/polish/delight"
- Wants celebrations designed (winners, streaks, reveals, score changes)
- Asks to design or review haptics (vocabulary, Core Haptics,
.sensoryFeedback) - Asks about sound effects, buzzers, countdown ticks, or fanfares
- Wants a feedback audit — do the right events fire the right channels?
- Is building a party/group game where the phone is shared, passed, or watched at a distance
Core Principles
1. Channels have different reach — match the channel to the audience
| Channel | Who perceives it |
|---|---|
| Haptics | Only the person holding the device |
| Screen motion | Whoever is looking at the screen |
| Audio | The whole room |
| Torch / flash | The whole room, even in noise |
A single-user utility can lean on haptics. A shared-phone or room-facing app (party games, kitchen timers, presentations) must put its signature moments on a room-scale channel. The most common juice failure: all feedback is haptic, and the phone is lying on a table.
2. Feedback scales with rarity
Tick < action confirmed < success < round complete < winner. If the rarest event (winning) fires the same pattern as a routine one (round end), the app has no climax. Reserve the biggest pattern, the confetti burst, and the fanfare for the rarest event.
3. Escalation must agree across channels
If the timer's ring turns amber at 10s and red at 5s, the haptic tier and any audio tick must escalate at the same thresholds. Cross-channel disagreement reads as broken, not layered.
4. Single-owner rule
Exactly one code layer fires feedback for a given event. When an engine and a view-store both react to "music stopped", the user gets a double-buzz. Decide the owner (usually the layer closest to the state machine) and make the other layer silent.
5. Juice amplifies meaning — it never decorates
Every effect must be attached to an event the user cares about. Ambient/always-on effects (background particles, looping glows) are texture, not feedback — keep them static or slow, and never let them compete with event feedback.

6. Every channel needs an accessibility story
- Motion → gate large-scale motion on Reduce Motion, with a static equivalent
- Haptics → user-facing toggle (the system provides no global haptics setting for Core Haptics)
- Sound → mute toggle independent of system volume; a deliberate, documented silent-switch policy
Decision Tree
What do you need?
│
├─ Which events should have feedback, and on which channels?
│ └─ → feedback-audit.md (event×channel matrix + three-lens audit)
│
├─ Design or review haptics (vocabulary, service architecture, APIs)
│ └─ → haptic-design.md
│
├─ Add a sound-effect layer (assets, latency, AVAudioSession coexistence)
│ └─ → sound-design.md
│
├─ HOW to animate a celebration/transition you've already decided on
│ └─ → design/animation-patterns (springs, transitions, symbol effects)
│
├─ Generate confetti / badge / milestone UI code
│ └─ → generators/milestone-celebration
│
└─ Animated SF Symbols for feedback moments
└─ → design/sf-symbols (preset vocabulary)Review Checklist
When reviewing an app's game feel, verify:
- Signature moments hit ≥2 channels (e.g. winner = motion + haptic + sound)
- Room-facing events use a room-scale channel (audio, display-size motion, torch)
- Rarity gradient exists — the rarest event has visibly/audibly the biggest feedback
- No channel disagreement — escalation thresholds match across visual/haptic/audio
- Single owner per event — no double-fire from two layers
- Score/number changes animate (
.contentTransition(.numericText())) — values never teleport - State changes transition — no hard cuts between phases of a flow
- Reduce Motion parity — every gated effect has a static equivalent conveying the same information
- User controls exist — haptics toggle; mute toggle if there's an SFX layer
- Loading/waiting states have anticipation — determinate progress or a live effect, not a bare spinner at a climactic moment
