What is threejs-app-director?

Instructions for building and upgrading general Three.js applications, which are browser-based 3D experiences. They cover viewers, configurators, simulations, visualizations, editors, and showcases.

Use them to plan or upgrade a Three.js application, route work to specialized 3D skills, and follow the required patterns for assets, spatial interaction, debugging, and browser release.

They help choose the right supporting guidance for models, materials, interaction, rendering, testing, and release. They also prevent adding game mechanics when the requested experience is not a game.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00038	$0.01017
Opus 5.5	$0.00015	$0.00407
Sonnet 5.5	$0.00008	$0.00203
Haiku 4.5	$0.00004	$0.00102

Measured 2mo ago against content hash 28eb0649ff5a, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

threejs-app-director 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.

The scan reads SKILL.md. This mod also ships 12 executable files (assets/threejs-vite-asset-viewer/src/asset-manifest.ts, assets/threejs-vite-asset-viewer/src/main.ts, assets/threejs-vite-asset-viewer/src/viewer/dispose.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Three.js App Director

Own the complete non-game 3D application outcome. Do not invent game objectives, scoring, failure, or progression unless the experience genuinely needs them.

Read references/app-patterns.md for the matching application archetype. For a fresh model, animation, asset-pack, material, material-pack, or Mint-world delivery whose asset is the requested product, read ../../references/asset-viewer.md and start from the packaged Asset Viewer scaffold. For imported-model orientation, manipulation, simulation, terrain, or other spatially complex work, read ../../references/spatial-contracts.md.

Route The Work

Need	Skill
Models, composition, materials, lighting, shaders, VFX	`../threejs-visual-systems/SKILL.md`
Cameras, controls, picking, selection, configuration, manipulation, UI	`../threejs-interaction-systems/SKILL.md`
Rendering, loading, input bugs, profiling, optimization	`../threejs-debug-profiler/SKILL.md`
Browser QA, visual regression, production release	`../threejs-qa-release/SKILL.md`
Game mechanics or game feel inside a mixed experience	`../threejs-gameplay-systems/SKILL.md`

Workflow

Inspect the existing stack, scene lifecycle, assets, interactions, UI, data ownership, loading states, target devices, and deployment constraints.
Define the app brief: user goal, primary 3D subject, essential interactions, camera/control model, state or data flow, loading/error behavior, outputs, and performance budget.
If the work needs Mint assets, resolve one Mint Project for the local codebase through ../../references/mint-project-workspaces.md. Infer its name from the app brief when no association or explicit destination exists.
Establish one owner for renderer, scene, camera, animation frame, resize, asset lifecycle, and disposal.
Use Mint MCP through ../../references/mint-mcp-assets.md when production assets are needed. Register ordinary artifacts and remote world runtime configuration in the project-root mint-assets.json through ../../references/asset-pipeline.md; stream world RAD manifests through ../../references/mint-world-splats.md.
Implement the smallest complete user journey before secondary polish.
Apply visual systems and interaction guidance appropriate to the archetype.
Reproduce and measure defects or performance issues before optimizing.
Follow ../../references/verification-policy.md: run the automatic minimum, then offer a scoped desktop/browser QA pass. Treat mobile as a separate approval.

What ships with it

Changes

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.
