71%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a thorough Three.js lighting reference with excellent actionability - every code example is complete and executable with proper imports. The main weakness is its length; at ~350 lines it reads more like a comprehensive reference document than a focused skill, and would benefit from splitting advanced topics into separate files. The workflow for shadow setup is clear but could include explicit validation/debugging steps.
Suggestions
Split advanced topics (Light Probes, Common Lighting Setups, Light Animation) into separate reference files and link from the main SKILL.md to improve progressive disclosure
Trim obvious inline comments (e.g., '// Modify at runtime', '// Properties') and consolidate the light type sections to reduce token count
Add a brief troubleshooting/validation workflow for shadows: 'If shadows don't appear: 1. Check renderer.shadowMap.enabled 2. Verify castShadow/receiveShadow on objects 3. Use CameraHelper to visualize frustum 4. Adjust bias if shadow acne appears'
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is comprehensive but quite long (~350 lines). Some sections like Light Helpers and Common Lighting Setups are useful but add bulk. The inline comments are mostly helpful, though some are obvious (e.g., '// Modify at runtime'). The overview table is efficient, but the sheer volume of code examples for every light type makes this feel more like a reference manual than a concise skill. | 3 / 5 |
Actionability | Every section provides fully executable, copy-paste ready code with correct import paths, constructor signatures, and property access patterns. The code covers common cases (shadow setup, IBL, light probes) with complete examples including necessary initialization steps like RectAreaLightUniformsLib.init(). | 5 / 5 |
Workflow Clarity | The Shadow Setup section provides a clear 3-step sequence (enable on renderer, enable on light, enable on objects). The skill includes debugging helpers (CameraHelper, LightHelper) and optimization guidance. However, there's no explicit validation/verification workflow - e.g., no 'check if shadows appear correctly, if not adjust bias' feedback loop, though the operations aren't destructive so this is a minor gap. | 4 / 5 |
Progressive Disclosure | The skill has good section headers and a 'See Also' section referencing related skills, but the content is monolithic - all light types, shadow configuration, IBL, light probes, common setups, and animation are inlined in one file. Advanced topics like Light Probes and Common Lighting Setups could be split into separate reference files. No bundle files exist to offload content to. | 3 / 5 |
