adds synthesized background music and sound effects to games via web audio api step sequencer, requiring zero external audio files or dependencies. wires game events to audio playback with browser autoplay policy handling and mute toggle.

qa-game adds playwright-based testing to game projects, covering boot verification, scene transitions, visual regression, performance budgets, and design-intent validation. it audits game internals and generates a test suite with fixtures.

add-feature guides developers through extending browser games by planning feature scope, reading existing architecture, implementing with strict patterns (eventbus, constants, state), and verifying integration without breaking existing systems.

quick-game scaffolds a minimal playable game prototype in phaser or three.js, prioritizing speed over polish. core loop (input, movement, fail, score, restart) lands on screen immediately, with explicit deferral of assets, audio, and deploy to separate skills.

use-template clones game templates from a manifest-backed gallery, auto-prompting users to select if no template ID is provided, then copies working code to a contextually-aware project directory.

promo-video automates recording of phaser game footage at 50 fps in mobile portrait format, using playwright video capture combined with ffmpeg speed-up to work around native 25 fps limitations.

design-game audits game visuals across multiple dimensions (color, animations, atmosphere, typography) and generates a scored report with ranked improvements. implementation follows a pattern-library approach via game-designer skill, writing all changes to constants and eventbus.

make-game scaffolds game development workflows from brainstorm through iteration, detecting project state and routing to appropriate tools. delegates procedural detail to referenced skills rather than specifying steps directly.

worldlabs generates photorealistic 3d environments via gaussian splats from text or images using the marble api, producing renderable spz scenes with physics colliders for game integration.

game-designer evaluates and enhances browser game visuals, atmosphere, and player experience through polish techniques like particle effects, color coherence, and feedback systems. lacks procedural depth and concrete triggering scenarios.

game-assets provides pixel art sprite generation via code matrices for browser games, with reference documentation on character archetypes and rendering functions, but lacks concrete execution steps and failure handling.

phaser covers foundational principles for building 2d browser games with phaser 3 and typescript, emphasizing core loop implementation, scene architecture, and event-driven communication patterns.

threejs-game provides architectural guidance for modular three.js game development with event-driven patterns and reference material, but lacks concrete procedures and specific invocation guidance.

record-promo captures autonomous gameplay footage for social media by spinning up a dev server, using playwright to record frames at high fps, and piping output through ffmpeg. incomplete, defers core logic elsewhere.

improve-game promises iterative game auditing and enhancement across multiple dimensions but lacks concrete procedural steps, decision criteria, and failure handling. the skill is abandoned mid-definition.

add-assets replaces geometric shapes with pixel art sprites for game entities. documentation is incomplete, procedure stops mid-sentence, and failure modes are not addressed.
