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 | $0.00056 | $0.01814 |
| Opus 5 | $0.00028 | $0.00907 |
| Sonnet 5 | $0.00011 | $0.00363 |
| Haiku 4.5 | $0.00006 | $0.00181 |
Grade A, and why
ue5-blueprint-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 12d 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 — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unreal Engine Blueprint — Audio Logic & Asset Management
Handle Blueprint audio logic: game event detection, parameter wiring to MetaSounds/Wwise, asset scanning, and audio component setup.
Blueprint Audio Architecture
Blueprints are the WHEN layer — they detect game events and route parameters to audio systems:
Game Event (overlap, anim notify, input)
→ Blueprint Logic (detect, filter, transform)
→ Audio Action (play sound, set RTPC, post event)
Audio Blueprint Nodes
Playback
| Node | Use | Spatial |
|---|---|---|
PlaySound2D |
UI, non-positional audio | No |
PlaySoundAtLocation |
One-shot 3D sound | Yes |
SpawnSoundAtLocation |
Persistent 3D sound (returns component) | Yes |
SpawnSound2D |
Persistent non-spatial | No |
Dialogue
| Node | Use |
|---|---|
PlayDialogue2D |
Non-spatial dialogue |
PlayDialogueAtLocation |

|---|---|
SetSoundMixClassOverride |
Override sound class volumes |
ClearSoundMixClassOverride |
Remove overrides |
PushSoundMixModifier |
Activate sound mix |
PopSoundMixModifier |

|---|---|
PostEvent |

SetRTPCValue |

SetSwitch |

Game Event Patterns
Animation Notify → Sound
AnimNotify_Footstep
→ Line Trace Down (surface detect)
→ Set Switch (Surface = result)
→ PostEvent (Play_Footstep)
Overlap Volume → Ambient
OnBeginOverlap
→ Set RTPC (Ambient_Volume = 1.0)
OnEndOverlap
→ Set RTPC (Ambient_Volume = 0.0)
State Change → Weather Audio
OnWeatherChanged (Rain/Snow/Wind/Clear)
→ Set State (Weather = new_state)
→ Set RTPC (Wind_Intensity = value)
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.

ue5-blueprint-audio is a skill published in the GitHub repository koshimazaki/UE-AUDIO-MCP (5 stars, last pushed 2mo ago), licensed MIT. It adds 56 tokens to every session and 1,814 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 2026-08-31.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
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…
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
