Quality

Content

68%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, token-efficient constraint/reference skill with concrete file and ID wiring and a validation hook. It is not a multi-step workflow, so workflow clarity is only adequate, and all detail is inlined in one file.

Suggestions

Add an explicit verification sequence (e.g., '1. make change; 2. run `npm test`; 3. only ship if static guards pass') to turn the 'Gotcha' into a real checkpoint loop.

Consider extracting the long welcome-modal and toolbar-palette specifications into a references/ file and linking from the body, to improve progressive disclosure.

DimensionReasoningScore

Conciseness

Dense with exact IDs, function names, and file paths; assumes codebase knowledge with no concept-padding. A few enumerations (e.g., the welcome-modal spec) run long, keeping it just below a 5.

4 / 5

Actionability

Instruction-only but highly actionable: concrete wiring targets ('#build-play-mode toggles body.tw-play-mode', 'keep aria-keyshortcuts=Escape') and explicit keep/do-not directives. No runnable code, which the rubric permits for instruction skills, but minor gaps keep it at 4.

4 / 5

Workflow Clarity

Organized as preservation rules with a 'Gotcha' validation pointer (npm test / static guards), but there is no explicit sequenced workflow or validate-fix-retry loop; checkpoints are implicit.

3 / 5

Progressive Disclosure

Single SKILL.md with no bundle directories, well-sectioned headers and no nested references; the inlined welcome-modal and toolbar detail could arguably live in a reference, so not a 5.

Description

71%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is tightly scoped to Tiny World Builder internals with a clear 'Use when' trigger and three concrete targets, making it highly distinct. It loses points on trigger-term breadth (niche jargon, no synonyms) and on action-verb specificity.

Suggestions

Add a second verb or explicit capability noun (e.g., 'Configure ... and preserve the Esc-to-Select invariant') so the 'what' is more than a single 'changing' verb.

Include a more user-natural synonym alongside the internal jargon (e.g., 'mode HUD', 'startup tool') to broaden trigger-term coverage.

DimensionReasoningScore

Specificity

Names the domain (Tiny World Builder) and three concrete capability targets — 'mode indicator', 'boot tool selection', 'Esc-to-Select behaviour' — tied to a single action verb 'changing'; comprehensive on targets but thin on distinct action verbs, so below 5.

4 / 5

Completeness

Has both an explicit 'when' ('Use when changing ...') and an implied 'what' (changing those three behaviours); the 'when' is specific but the 'what' is a single thin action, so not a 5.

4 / 5

Trigger Term Quality

Covers the app's internal trigger phrases but they are niche jargon with no synonyms or common variations, fitting 'some relevant keywords but missing common variations'.

3 / 5

Distinctiveness Conflict Risk

Scoped to one app's specific internal behaviours, giving a clear niche with distinct triggers and minimal conflict risk.
