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 | $0.00110 | $0.03269 |
| Opus 5.5 | $0.00044 | $0.01308 |
| Sonnet 5.5 | $0.00022 | $0.00654 |
| Haiku 4.5 | $0.00011 | $0.00327 |
Grade A, and why
dungeon-os-threejs 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 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.
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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Dungeon OS — Three.js World Builder
The 3D dungeon is a 2.5-D isometric night scene where six LLM-driven agents move around and build an "Agentic OS." The renderer is a view of game state — it reads state over a WebSocket and never owns game logic.
Before writing render code, read the two source-of-truth files (don't trust memory):
agora-game-server/static/index.html— the entire renderer (single-file vanilla ESM Three.js, ~1500 lines).agora-game-server/game_state.py—GameEngine/DungeonState(the tilemap + entities the scene renders). Run it:cd agora-game-server && python mcp_server.py→ openhttp://localhost:5174. The dungeon process is launched/restarted by the loop's standard procedure; after editingindex.htmlyou only need a browser hard-refresh (it's served raw, no build step).
GROUND TRUTH — the actual stack (build to match this, not a target)
| Concern | Reality |
|---|---|
| Three.js | r0.170.0, vendored at agora-game-server/node_modules/three. ESM via <script type="importmap">: "three" → /node_modules/three/build/three.module.js, "three/addons/" → /node_modules/three/examples/jsm/. |
| Renderer | WebGLRenderer({ antialias:true }) — synchronous, no await init(). setPixelRatio(min(dpr,2)), shadowMap.enabled, PCFSoftShadowMap, ACESFilmicToneMapping, toneMappingExposure ≈ 1.45. (A WebGPU build three.webgpu.js is vendored but UNUSED — see Upgrade Path before touching it.) |
| Camera | OrthographicCamera iso, d ≈ 15, position (d,d,d) looking at (0,0,0), OrbitControls (rotation NOT locked yet). |
| Atmosphere | scene.background = 0x0a0e18 (deep night); scene.fog = new THREE.Fog(0x0a0e18, 45, 95) (linear, matches bg). |
| Lights | AmbientLight(0x37466a, .5) + cool moonlight DirectionalLight(0x9fb2da, 1.0) with a tight shadow frustum (±16) for crisp shadows + HemisphereLight(0x5a6e98, 0x2a2420, .5) + ~9 warm torch PointLights from state (radius, decay 1.8) + cheap emissive flame meshes flickered each frame. Point lights are sparse ON PURPOSE. |
| Floors/walls/props | The Quaternius "Ultimate Modular Ruins Pack" (Floor_Standard, Floor_Diamond, Wall*, Statue_*, Flag_Wall, columns…). Loaded once into a ruinsCache, then one clone per tile (floors are real models, not boxes; one tinted template per zone colour). |
| Agents | 6 (King Aldric, Sgt Voss, Dame Elara, High Priest Orin, Shadow Kael, Sage Mira). Quaternius glTF, cloned with SkeletonUtils.clone, one AnimationMixer each, tweened movement, CanvasTexture Sprite labels (name / HP bar / thought bubble). |
| State→view | Client opens WS :5175, gets a snapshot, applies incremental events (entity_moved/state/health/thought/face, tasks_update, effect_added, os_build, trust/HUD). Reads, never writes. HTTP is :5174. |
| Post-processing | NONE yet. EffectComposer, UnrealBloomPass, SSAOPass, GTAOPass, SMAAPass, OutputPass are all present in node_modules/three/examples/jsm/postprocessing/ and unused. This is the single biggest visual win available. |
What ships with it
1 file 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.

dungeon-os-threejs is a skill published in the GitHub repository DanceNitra/agora (3 stars, last pushed 7d ago), licensed MIT. It adds 110 tokens to every session and 3,269 once invoked, about $0.0004 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 2026-08-31.
