swipi-engine

Reference for generating game assets (sprites, backgrounds, tilemaps, audio) and wiring them into asset-pack.json. Invoked by the swipi-workflow skill during Phase 3, or any time the user asks Claude to add, replace, or debug game assets.

Pick the correct swipi game archetype (platformer, top_down, grid_logic, tower_defense, ui_heavy) from a user prompt using physics-first logic. Invoke from the swipi-workflow skill during Phase 1, or any time you need to decide which template module a game belongs to.

Pre-build consistency checklist and verify→diagnose→repair loop for swipi games. Invoke during Phase 6 of the swipi-workflow, or any time a build/test/dev command fails, or whenever the user reports that a generated game does not run.

Universal 6-section Game Design Document schema used by every swipi archetype. Invoke during Phase 2 of the swipi-workflow before writing GAME_DESIGN.md, or any time the user asks for the structure of a swipi GDD.

Design rules, template API, and implementation guide for grid_logic-archetype games (discrete grid + turn-based or step-based motion — Sokoban, Fire Emblem, Match-3, Pikachu-grid puzzles). Invoke during Phase 2 for GDD drafting and Phase 5 as the reading-list index.

Design rules, template API, and implementation guide for platformer-archetype games (side view + gravity — Mario, Street Fighter, Metal Slug, Castlevania). Invoke during Phase 2 to inform GDD drafting, and again during Phase 5 as a reading-list index.

Design rules, template API, and implementation guide for top_down-archetype games (top-down + free continuous motion — Zelda, Isaac, Vampire Survivors, twin-stick shooters). Invoke during Phase 2 for GDD drafting and Phase 5 as the reading-list index.

Design rules, template API, and implementation guide for tower_defense-archetype games (fixed enemy paths + waves + placeable towers — Kingdom Rush, Bloons TD, Hajimi Defense). Invoke during Phase 2 for GDD drafting and Phase 5 as the reading-list index.

Design rules, template API, and implementation guide for ui_heavy-archetype games (UI-driven, no physics — card battles, visual novels, quiz games, trivia fighters like K.O.F Celestial Showdown). Invoke during Phase 2 for GDD drafting and Phase 5 as the reading-list index.

Authoritative 6-phase workflow for building a playable Phaser web game from a user prompt. Use whenever the user asks Claude to "build a game", "make a game", "scaffold a game", or triggers the /swipi-new slash command. Orchestrates classification, scaffolding, GDD generation, asset generation, config wiring, code implementation, and verification.
