game-juice

game-juice is a skill for Claude Code from JSON-OBJECT/claude-code. It costs 153 tokens per session (3,689 once invoked), scanned A, original, no licence file.

A design workflow for making browser interfaces feel like Japanese gacha or casual mobile games. Gacha games commonly use repeated rewards, effects, and feedback to make actions feel lively, especially on tall phone screens.

In plain words
What is it for?
It is for adding damage numbers, hit effects, screen shake, springy buttons, combo feedback, and other game-feel details to browser UI, especially in a vertical 9:16 layout.
Why use it?
It helps communicate game state through visible and physical-feeling responses instead of making interactions feel flat. It focuses on feedback such as impacts, shakes, and animated controls.

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

game-juice scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
