Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 5.1 | $0.00061 | $0.01534 |
| Opus 5 | $0.00030 | $0.00767 |
| Sonnet 5 | $0.00012 | $0.00307 |
| Haiku 4.5 | $0.00006 | $0.00153 |
Grade A, and why
game-feel 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

game-feel is a skill published in the GitHub repository rshankras/claude-code-apple-skills (713 stars, last pushed 1mo ago), licensed MIT. It adds 61 tokens to every session and 1,534 once invoked, about $0.0003 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 2026-08-30.
