Use when implementing or reviewing AI image generation integrations, provider adapters, prompt builders, OpenAI/other image API flows, generate-edit-fix workflows, API-key handling, provenance metadata, generated asset queues, or UI panels for creating sprites on demand. Do not use for local pixel-fixing algorithms unless the task involves generated-image handoff.
Use when implementing, reviewing, or optimizing visual rendering, preview viewports, canvas layers, worker/offscreen rendering, sprite animation playback, or performance instrumentation. Applies to Canvas2D, OffscreenCanvas, WebGL, Three.js preview surfaces, zoom/pan rendering, dirty-region drawing, and avoiding React render bottlenecks. Do not use for pure algorithm work unless rendering performance is involved.
Use when implementing or reviewing a command-line interface, local API, batch processor, MCP server, automation-friendly commands, machine-readable outputs, or skill/tool integrations that call the app’s pixel-fixing and export functionality. Applies to deterministic CLI behavior, JSON schemas, exit codes, local HTTP APIs, MCP tool definitions, and batch workflows. Do not use for visual UI work unless exposing that workflow through CLI/API/MCP.
Use when implementing or reviewing exporters, importer scripts, presets, or documentation for Godot, Unity, Phaser, TexturePacker, Tiled, LDtk, or other game engines/frameworks. Applies to texture settings, nearest filtering, sprite slicing, pivots, animation import, tileset metadata, and engine-specific bundles. Do not use for the generic sprite manifest unless engine adaptation is involved.
Use when choosing, adding, updating, or reviewing dependencies; drafting repo license/NOTICE files; evaluating whether a package can be used in an open-source and commercially sold tool; or checking attribution obligations. Applies to npm, Rust, WASM, image-processing libraries, AI SDKs, desktop shells, and embedded assets. Do not use for ordinary coding tasks unless dependency or license risk is involved.
Use when implementing, debugging, or reviewing the image-processing core that converts AI-generated pseudo-pixel art into true grid-aligned pixel art. Applies to pseudo-pixel grid detection, block-aware downsampling, palette reduction, alpha/background cleanup, frame-stable palettes, and pixel-art quality tests. Do not use for general UI layout, engine exporters, or AI provider integration unless the task directly touches the pixel-fixing algorithms.
Use when implementing or reviewing the future sprite sheet player, animation preview controls, controllable character sandbox, scene preview, 2D test arena, or Three.js-based 3D sprite/object sandbox. Applies to playback timing, input controls, camera, sprite billboarding, texture filtering, scene setup, performance, and validating assets in motion. Do not use for the pixel-fixing algorithms unless the task involves visual playback or sandbox validation.
Use when implementing or reviewing sprite sheet slicing, character sheet normalization, animation timing metadata, frame tags, pivots, margins, spacing, padding, extrusion, PNG frame sequences, sheet atlases, or generic JSON manifests. Do not use for engine-specific import scripts unless combined with the game-engine-export skill.
