63%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A dense, project-specific constraint map with excellent actionability — precise function names, file locations, constants, and gotchas Claude could not rediscover cheaply — plus a genuine validation section. Its weaknesses are length (the material/strata and mooring sections run long) and a monolithic structure that inlines three separable subsystems instead of splitting them into reference files.
Suggestions
Split the self-contained subsystems into one-level-deep reference files (e.g. references/mooring-cables.md, references/planes.md, references/island-materials.md) and keep SKILL.md as a short overview with clearly signaled links.
Tighten the island shell material/strata and mooring sections to directive form — cut the design-history rationale ('which is what "island without a base" was', the backdrop fall-through explanation) down to the rule it motivates.
Add an error-recovery loop to the Validation section: what to check and fix when `node tools/check.js` fails or the 8×8 vs 20×20 visual check regresses, and re-run.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Almost every line is project-specific knowledge Claude could not know (constants like `EDITABLE_ISLAND_PROP_LOCAL_Z = -2.84`, pick conventions, rebuild flow), so there is no padding with general concepts — but ~300 lines of dense prose includes sections that could be tightened, e.g. the long shader/material rationale paragraphs and repeated 'keep / do not' directives that restate the same constraint. This sits at anchor 3 ('mostly efficient but some unnecessary explanation or could be tightened'), below 4 because the material/strata and mooring sections carry noticeably compressible rationale. | 3 / 5 |
Actionability | Guidance is highly concrete: named functions with file and approximate line locations (`buildHomeBorder()` ~line 16340, `pickEditableIslandEngine` in `18-scene-pick-xr.js`), exact constants (`DEFAULT_AZIMUTH = π * 0.32`, `target.z - (GRID * 0.5) - (GRID * 2)`), a runnable command (`node tools/check.js`), and precise do/don't rules. Not 5 because it is instruction-only with no copy-paste code snippets for the most common edits (e.g. how to register a new emitter or swap the banner data URL), leaving minor gaps. | 4 / 5 |
Workflow Clarity | The `buildHomeBorder()` rebuild sequence is laid out step-by-step, the 'Validation' section gives explicit post-change checkpoints (`node tools/check.js`, visual check at 8×8 and 20×20, banner readability, L↔R audio pan), and placement/deletion flows name the exact call order. Not 5 because validation has no error-recovery loop (what to do when `tools/check.js` fails or the visual check regresses) and most subsystem sections are constraint lists rather than sequenced steps. | 4 / 5 |
Progressive Disclosure | Section headers are clear and topical, but the skill is a single ~300-line monolith with no bundle files at all (no references/, scripts/, or assets/ exist), while several self-contained subsystems — mooring cable styles/interaction, the plane/crop-duster system, island shell materials/strata — are prime candidates for one-level-deep reference files. This matches anchor 3 ('some structure but could be better organized; content that should be separate is inline') rather than 2, since the inline content is well-sectioned and navigable, and the file paths cited (e.g. `23-particles-clouds.js`) point to the project codebase being edited, not missing skill references. | 3 / 5 |
