Quality

Content

72%

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

A lean, well-organized instruction skill that assumes Claude's competence and avoids fluff, but it provides design/QA checklists rather than concrete implementation guidance or a sequenced workflow. Adding a few specific APIs/code patterns and a brief QA sequence would lift actionability and workflow clarity.

Suggestions

Add concrete implementation anchors — e.g., specific safe-area APIs (env/safe-area-inset), touch event patterns, and example quality-setting values — to move actionability from checklist-level to executable.

Turn the Performance and QA test list into a short ordered QA sequence with a pass/fail checkpoint (e.g., run each item, log results, only ship when all pass) to add workflow clarity.

Consider one small representative code snippet (e.g., a minimal touch-movement + safe-area HUD layout) so the guidance is copy-paste ready.

DimensionReasoningScore

Conciseness

Lean and efficient with no padding: it assumes Claude knows Three.js and mobile browsers, listing only task-specific guidance. Not a 2 because there is no unnecessary explanation or filler to tighten.

3 / 3

Actionability

Gives concrete, specific checklists ('Test touch targets, multi-touch, long sessions, audio unlock, pause/background return, reduced motion, low-end quality') and clear constraints, but stays at the 'what' level with no implementation detail (no touch-handling patterns, safe-area APIs, or quality settings). Not a 3 because the guidance is not copy-paste ready or executable; not a 1 because the items are specific rather than vague.

2 / 3

Workflow Clarity

Content is organized into clear topical sections with a QA test checklist, but there is no sequenced workflow or validation checkpoints. Not a 3 because no explicit sequence or feedback loop is present; not a 1 because the structure and test list provide clear, organized guidance rather than missing steps.

2 / 3

Progressive Disclosure

Under 50 lines with no bundle files and no need for external references, organized into three well-separated sections. Per the simple-skills note, well-organized sections alone warrant a 3 here.

Description

100%

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

A strong, concise description that clearly states both capability and trigger conditions with a rich set of natural trigger terms. It carves out a distinct niche and is unlikely to conflict with other skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('Build, tune, or test a Three.js game') plus a comprehensive set of specific capabilities (touch movement, target selection, safe areas, responsive HUD, battery/performance budgets, real mobile browser QA). Not a 2 because the action list is broad and concrete rather than naming only a domain and a few actions.

3 / 3

Completeness

Explicitly states what ('Build, tune, or test a Three.js game for mobile web') and when via an explicit 'Use for ...' trigger clause. Not a 2 because the 'when' guidance is explicit, satisfying the 'Use when...' requirement.

3 / 3

Trigger Term Quality

Covers natural terms a user would say ('Three.js game', 'mobile web', 'touch movement', 'safe areas', 'portrait/landscape', 'responsive HUD', 'mobile browser QA'). Not a 2 because it spans the common user phrasings rather than a single technical label.

3 / 3

Distinctiveness Conflict Risk

The mobile-Three.js-games niche is highly specific with distinct triggers, making collision with other skills unlikely. Not a 2 because the combination of 'Three.js', 'mobile web', and the listed touch/HUD/QA triggers carves out a clear, non-overlapping niche.
