phaser-2d-game

Implement 2D browser games with Phaser. Use when the user wants a Phaser, TypeScript, and Vite stack for scenes, gameplay systems, cameras, sprite animation, and DOM-overlay HUD patterns.

Quality

Content

61%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-organized, lean architecture-directions document that clearly separates concerns (systems vs. scenes, DOM HUD vs. canvas) and flags anti-patterns. Its main gaps are the complete absence of executable guidance — no code or commands — and references that escape the skill bundle and cannot be resolved within it.

Suggestions

Add at least one minimal executable example (e.g., a thin Phaser scene reading system state in TypeScript, or a manifest snippet) so a Claude can start without guessing the concrete module split.

Include or inline the essential content of phaser-architecture.md, or ensure the referenced file ships in the skill's references/ directory so the 'Default Directory Shape' section isn't just a pointer to an unresolvable path.

Give the architecture guidance a sequenced build order (project scaffold → manifest → systems → scene wiring → HUD overlay) with a checkpoint (e.g., run vite dev and confirm the boot scene loads) to strengthen workflow clarity.

DimensionReasoningScore

Conciseness

The body is lean and sectioned with terse bullets (e.g., 'Make scenes thin', the asset folder list, the anti-patterns list) and does not explain Phaser basics. Not 5 because filler like 'Use this skill for the main execution path in this plugin' and the 'Phaser is the default stack... because it handles rendering, timing...' justification could be trimmed; not 3 because such padding is minor.

4 / 5

Actionability

Guidance is structurally concrete — 'Keep gameplay state outside Phaser scenes', the four thin scene types, the asset folders, 'one integration boundary' — but there is no code, command, or worked example, and the file that promises the concrete module split ('../../references/phaser-architecture.md') is not present in the bundle. It matches 'some concrete guidance but incomplete' rather than mostly-executable guidance.

3 / 5

Workflow Clarity

The Architecture section is numbered (1-4) and gives a rough structural order, but there is no sequenced process for actually building a game and no validation checkpoints or feedback loops. Not 4 because no explicit ordered steps with checkpoints exist; not 2 because the numbered architecture list and clearly separated concerns do form a coherent rough sequence.

3 / 5

Progressive Disclosure

Sections are well-organized and references are clearly signaled in a dedicated References section, with detail appropriately deferred ('See ../../references/phaser-architecture.md for a concrete module split'). Not 5 because every referenced path (../../references/, and three sibling ../<skill>/SKILL.md files) points outside this skill's bundle, and no bundle files exist to back them, so the navigation cannot be verified to resolve.

Description

70%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 concise, uses third person, and includes an explicit 'Use when...' clause with a distinct Phaser-anchored niche. Its main weaknesses are limited action coverage (one verb) and a 'when' clause phrased around stack selection rather than natural user requests like building a 2D game.

Suggestions

List 2-3 concrete capabilities (e.g., 'Build scenes, gameplay systems, and cameras; wire sprite animation; layer a DOM HUD') so the 'what' matches the several-specific-actions anchor.

Rephrase the trigger around what users actually ask for — e.g., 'Use when the user asks to build a 2D browser game, or mentions Phaser, TypeScript, Vite, or HTML5/web games' — to cover natural synonyms.

Sharpen distinctiveness by making 'Phaser' the primary trigger and demoting generic terms like 'HUD' and 'sprite animation' that overlap sibling game skills.

DimensionReasoningScore

Specificity

Quotes: 'Implement 2D browser games with Phaser' plus stack enumeration 'Phaser, TypeScript, and Vite'. It names the domain and a single concrete action with stack details, but does not list multiple distinct capabilities (comparable to 'Processes PDF files and extracts content'), so it matches the 1-2-concrete-actions anchor rather than the several-specific-actions anchors.

3 / 5

Completeness

Quotes: 'Implement 2D browser games with Phaser' (clear what) and 'Use when the user wants a Phaser, TypeScript, and Vite stack for scenes, gameplay systems, cameras, sprite animation, and DOM-overlay HUD patterns' (explicit when). Both are present, but the 'when' is unnaturally phrased — users ask to build a game, not to 'want a stack' — so it could be more explicit and user-natural.

4 / 5

Trigger Term Quality

Quotes: '2D browser games', 'Phaser', 'TypeScript', 'Vite', 'sprite animation', 'DOM-overlay HUD' — good natural keyword coverage a user would say. Not 5 because common synonyms like 'web game', 'HTML5 game', or 'game loop' are missing; not 3 because the core natural terms users would actually use are present.

4 / 5

Distinctiveness Conflict Risk

Quotes: 'Phaser', 'TypeScript, and Vite stack' — a mostly distinct niche trigger. Not 5 because broader terms like '2D browser games', 'sprite animation', and 'HUD' create minor overlap risk with closely related game-development skills (the body itself lists sibling game skills); not 3 because the stack-specific triggers are largely distinct.
