AG Kit is a toolkit that gives Google Antigravity coding agents a structured workspace with rules, skills, specialist agents, workflows, persistent memory, orchestration, MCP guidance, and a safety hook. It is for building and operating agent workflows in Antigravity, and its catalogue entries provide parts of that workspace contract.

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 | $0.00018 | $0.01319 |
| Opus 5.5 | $0.00007 | $0.00528 |
| Sonnet 5.5 | $0.00004 | $0.00264 |
| Haiku 4.5 | $0.00002 | $0.00132 |
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.

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.
- 1mo ago First seen · 191 lines · 18 tokens per session scan A 5cfa7e0a750c
game-audio is a skill published in the GitHub repository vudovn/ag-kit (8,199 stars, last pushed 3d ago), licensed MIT. It adds 18 tokens to every session and 1,319 once invoked, about $0.0001 per session on Opus 5.5. 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.

godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…

Generate motion from joint-position trajectories, rhythm and contact constraints through IK; refine bone orientation against the action, then export, retarget and validate on the target mesh.
