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, highly specific contract document that gives Claude exact APIs, keys, and files to route edits through, with a real validation section. Its weaknesses are repetition (especially the clipboard-preservation rule), no error-recovery loop around validation, and no progressive disclosure despite a length that clearly warrants splitting into reference files.
Suggestions
Consolidate the repeated 'must not overwrite the user's explicit copy/cut clipboard' rule into one stated invariant in the Clipboard section and reference it from the individual bullets.
Split the Stamps panel, Layers dialog, and Selection properties rule sets into references/ files (e.g. references/stamps-panel.md, references/layers-panel.md), keeping SKILL.md as a short overview with one-level-deep pointers.
Add a feedback loop to the Validation section: what to do when the syntax check, npm test, or browser-check fails (fix, re-run, only proceed when passing).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is project-specific with no padding of concepts Claude already knows, but it can be tightened: "must not overwrite the user's explicit copy/cut clipboard" is repeated nearly verbatim across at least six bullets (lines 47-58), and bullets like the fence-leveling rule run long. This fits 'mostly efficient but could be tightened' better than the noticeably-verbose anchor at 2. | 3 / 5 |
Actionability | Names exact executable surfaces — `setCell(x, z, opts)`, `applyToolToCell()`, `replaceWorldCoords()`, `tinyworld:asset-templates.v1`, `engine/world/33-radial-menu.js`, `window.__tinyworldSelection` — making the guidance concretely actionable for code edits. Not a 5 because no runnable snippets or command examples beyond the validation section are given, leaving minor gaps for the less-standard flows. | 4 / 5 |
Workflow Clarity | The content is a rule catalog rather than a step sequence, but it closes with an explicit validation section ("Run the inline script syntax check, `npm test`, and `npm run build`. " plus a browser-check list covering the risky batch operations: "selected bulk placement, copy/paste/templates, duplicate"). Not a 5 because there is no failure/recovery feedback loop (what to do when a check fails), and the destructive/batch operations have validation listed only once at the end. | 4 / 5 |
Progressive Disclosure | The body is well-sectioned ("Clipboard and templates", "Selection properties", "Stamps panel", "Layers dialog") but is a ~200-line monolith with no bundle files at all — the Stamps-panel and Layers-dialog rule sets in particular are clearly separable reference material. This matches 'some structure but content that should be separate is inline'; it is not a 2 because section headers and consistent bullet format keep it navigable. | 3 / 5 |
