Threejs Skill Router

Three.js Visual Skill Router

Treat the model's Three.js knowledge and official documentation as prerequisites. Load only the expertise that changes the visual result.

Route by the visual system being authored

Execution order

For a new procedural scene:

1. Define a visual contract: subject, scale, camera distance, motion, and target frame budget.
2. Load $threejs-camera-direction when framing, lens, camera frame, or mode transitions affect the target.
3. Load the subject-generation skill.
4. Add $threejs-procedural-animation when object motion requires authored phases, moving frames, or spring convergence.
5. Add $threejs-procedural-fields when multiple visual channels must share coherent structure.
6. Add lighting/shadows and atmosphere only after silhouette and material masks read without effects.
7. Add $threejs-image-pipeline last.
8. Load only the atomic image effects actually needed.
9. Use $threejs-visual-validation for a deterministic evidence set.

Routing constraints

• Do not load a skill for API setup alone. Inspect the installed Three.js version and use official docs.
• Do not route “make it beautiful” directly to post-processing. Find the missing authored system.
• Prefer one strong, inspectable visual rule over several independent noise layers.
• When adapting a supplied reference, preserve the mechanism that creates its character. Do not reduce it to a generic effect category.
• Keep source-space, world-space, and screen-space systems separate unless the composition explicitly requires coupling.
• If no retained skill matches, state that the pack lacks expert coverage for that system. Do not stretch the nearest skill to cover it.

Acceptance gate

A routed task is incomplete until the implementation exposes:

• deterministic seed or reproducible inputs;
• visual debug modes for its controlling fields;
• parameters grouped by perceptual role;
• an intentional mechanism-backed quality or resolution tier when the system defines one;
• a no-post baseline that still reads.
