.agent/skills/game-development/game-audio/SKILL.md

game-audio is a skill for Claude Code from diillson/chatcli. It costs 18 tokens per session (1,319 once invoked), scanned A, a copy of game-audio, Apache-2.0.

Guidance for creating game sound effects, organizing music and other audio, and making sounds respond to what happens during play.

In plain words
What is it for?
Useful for planning music, sound effects, ambient sounds, interface sounds, voice, recording, synthesis, sample libraries, and layered effects.
Why use it?
It helps decide which sounds matter most when several compete and how to produce them within the project's time and skill limits.

This is diillson/chatcli's own configuration. It tells Claude Code how to work on chatcli itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything chatcli configures →

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-audio 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.

Origin

Game Audio Principles

Sound design and music integration for immersive game experiences.


1. Audio Category System

Category Definitions

Category Behavior Examples
Music Looping, crossfade, ducking BGM, combat music
SFX One-shot, 3D positioned Footsteps, impacts
Ambient Looping, background layer Wind, crowd, forest
UI Immediate, non-3D Button clicks, notifications
Voice Priority, ducking trigger Dialogue, announcer

Priority Hierarchy

When sounds compete for channels:

1. Voice (highest - always audible)
2. Player SFX (feedback critical)
3. Enemy SFX (gameplay important)
4. Music (mood, but duckable)
5. Ambient (lowest - can drop)

2. Sound Design Decisions

SFX Creation Approach

Approach When to Use Trade-offs
Recording Realistic needs High quality, time intensive
Synthesis Sci-fi, retro, UI Unique, requires skill
Library samples Fast production Common sounds, licensing
Layering Complex sounds Best results, more work

Layering Structure

Layer Purpose Example: Gunshot
Attack Initial transient Click, snap
Body Main character Boom, blast
Tail Decay, room Reverb, echo
Sweetener Special sauce Shell casing, mechanical

3. Music Integration

Music State System

Game State → Music Response
│
├── Menu → Calm, loopable theme
├── Exploration → Ambient, atmospheric
├── Combat detected → Transition to tension
├── Combat engaged → Full battle music
├── Victory → Stinger + calm transition
├── Defeat → Somber stinger
└── Boss → Unique, multi-phase track

Transition Techniques

Technique Use When Feel
Crossfade Smooth mood shift Gradual
Stinger Immediate event Dramatic
Stem mixing Dynamic intensity Seamless
Beat-synced Rhythmic gameplay Musical
Queue point Next natural break Clean

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.
