Resumen

Convert a web game idea (even a vague one like "build a Raiden-type game" or "make a card game") into a complete Codex /goal-ready Phaser 3 project — runnable scaffold, goals-plan.md, and all goal folders (GOAL.md + VERIFY.md + PROGRESS.md) generated at once. Auto-detects genre (shoot-em-up, card game, platformer, tower defense, puzzle), asks clarifying questions in focused batches, scaffolds a runnable TypeScript + Vite + Phaser 3 skeleton with state bridge for automated verification via Playwright, decomposes into 5-7 goals following a universal build order, and emits tailored /goal commands. Handles bullet hell, endless runner, match-3, solitaire, shmup, side-scroller, defense, and other genre variants. For browser-based 2D Phaser 3 games only — not 3D, multiplayer, RPGs, or non-browser platforms.

webg-spec-to-goal — Vague Game Idea → Complete Codex /goal Project

Turn a rough web game idea into a runnable Phaser 3 project scaffold plus every goal folder Codex /goal needs to build it autonomously:

Games naturally decompose into 5-8 goals following a universal build order. This skill generates all goals at once — no checkpoint between plan and generation.

Extend mode: This skill also supports extending an existing game with new features. When the user explicitly states they want to extend an existing game, the skill reads the current project state and generates additional goals that continue the sequence.

Why this skill exists

Games have a predictable build order: scaffold → core mechanic → enemies/content → progression → UI → polish. This skill exploits that pattern to collapse the entire "idea → goal bundle" pipeline into one conversation that:

auto-detects genre from the description and tailors everything to it
asks 2-3 rounds of clarifying questions (each with options + recommendation)
writes a runnable scaffold (boots to a blank Phaser scene out of the box)
generates all goal folders at once with genre-aware decomposition
bakes in state bridge verification (window.__GAME_STATE__ + Playwright)

Genre system

Five base genres, each with known variants:

Genre	Variants	Physics	Key Data Structures
shoot-em-up	bullet hell, shmup, Raiden-type, vertical/horizontal shooter	Arcade	bullet pools, wave spawners, hitboxes
card-game	solitaire, matching, deck-builder, poker variant	None	deck, hand, discard pile, card state
platformer	endless runner, side-scroller, precision platformer	Arcade	tilemap, player body, collectibles
tower-defense	lane defense, creep wave, placement strategy	None (path-based)	tower registry, enemy path, wave queue
puzzle	match-3, sliding, Tetris-type, word game	None or Arcade	grid state, match detection, gravity

Variant mapping: Map the user's description to a base genre. "Bullet hell" → shoot-em-up. "Endless runner" → platformer. "Match-3" → puzzle. "Solitaire" → card-game. Confirm with the user.

Unsupported types — hard stop:

RPG / JRPG (content-heavy, dialogue trees, save systems)
Simulation (open-ended state)
Racing (continuous physics, track design)
3D games (Phaser is 2D only)

Genre determines: Phaser physics config, data structures in scaffold, goal decomposition order, state bridge fields, and verification patterns in every VERIFY.md.

Core flow — 7 steps

New game mode (default)

Probe — inspect cwd for existing projects, conflicts, or extend intent.
Classify — auto-detect genre from description, ask user to confirm.
Ask — 2-3 rounds of clarifying questions (max 3 rounds).
Scaffold — write runnable game skeleton.
Plan — write goals-plan.md with goal sequence.
Write — generate all goal folders at once (including QC checkpoint as the final goal).
Hand off — print file paths + /goal commands.

Extend mode (user explicitly states intent)

Probe — detect existing project, read goals-plan.md + state bridge to understand current state.
Classify — identify what genre the existing project is (from its goals-plan.md or AGENTS.md).
Ask — 1-2 rounds: what features to add, scope, whether to include QC checkpoint.
(Skip scaffold — project already exists.)
Plan — append new goals to existing goals-plan.md.
Write — generate new goal folders only (continuing goal numbering from highest existing).
Hand off — print new file paths + /goal commands for the new goals only.

Never write files until confidence is at 95%+.

Step 1 — Probe

Before asking the user anything, inspect the cwd.

Signal	What it tells us
`package.json`	Existing project — check for Phaser in deps
`package.json` → Phaser 3 in deps	Existing Phaser project → check if extend mode
`tsconfig.json`	TypeScript already configured
`vite.config.*`	Build tool already in place
`src/` with Phaser imports	Existing game code → check if extend mode
`goals/` folder	Previous goal runs; check for slug collision
`goals-plan.md`	Existing roadmap → strong signal for extend mode
`AGENTS.md`	Existing conventions to respect
`.gitignore`	Check coverage for node_modules, dist/
`index.html`	Existing entry point
`tests/` with Playwright	Test infra already in place

New game mode

Existing Phaser project detected AND user did NOT express extend intent? Stop. Print:

This directory already contains a Phaser project. Would you like to extend it with new features (extend mode), or should we scaffold a new game in a different directory?

Extend mode detection

The user explicitly states they want to extend an existing game (e.g., "add a boss fight to my shmup", "extend the game with a new level", "add power-ups to the existing game"). When this happens:

Read goals-plan.md to determine: genre, variant, highest goal number, state bridge state.
Read src/state-bridge.ts to see current fields.
Read AGENTS.md for project conventions.
Note the highest existing goal number (e.g., 08) — new goals start at N+1.

If goals-plan.md doesn't exist but it's clearly a Phaser project made by this skill (has state-bridge.ts, goals/ folder), reconstruct the context from the goal folders.

Step 2 — Classify

Read the user's game description and auto-detect the genre. The variant mapping table in references/genre-templates.md has the full mapping. Quick process:

Scan for genre keywords (see genre table above).
Map variants to base genre.
Present the detection to the user for confirmation:

Based on your description, this sounds like a shoot-em-up (Raiden-type vertical shooter). Is that right, or should I classify it differently?

If the description is ambiguous, present 2-3 candidate genres with reasoning and ask the user to pick.

If the description maps to an unsupported type (RPG, simulation, racing, 3D), stop immediately with a clear explanation of why it's out of scope.

Step 3 — Ask clarifying questions

Use the AskUserQuestion tool when available. Fall back to natural-language Q&A with the same shape: 2-4 questions per round, recommended option first and labeled (Recommended), plus a one-line reason.

Aim for 2-3 rounds. Max 3 rounds. Skip questions already answered by the spec or probe.

Round 1 — Identity + Resolution

Game name / slug: Suggest kebab-case from the game description (e.g., "space-raiders"). Must be a valid npm package name and directory name.
Resolution: 800x600 (Recommended — standard 4:3, works on most screens) / 1024x768 / 960x540 (16:9) / Custom.
Confirm genre: "I detected [genre]. Correct? If not, which genre fits better?"

Round 2 — Mechanics + Scope

Acceptance criteria: Draft 4-6 AC bullets from the spec, then ask the user to confirm, edit, or add. Don't make them write ACs from scratch.
Out of scope: Suggest boundaries (multiplayer, mobile-specific controls, save/load, procedural generation, online leaderboards).
Genre-specific mechanics: Tailor to the genre:
- shoot-em-up: weapon types, power-up system, boss fights?
- card-game: hand size, draw rules, win condition?
- platformer: jump physics, wall-jump, double-jump?
- tower-defense: tower types, upgrade tiers, enemy variety?
- puzzle: grid size, match rules, scoring?

Round 3 — Art + Audio + Optional Goals

Art style: Pixel art (Recommended for most games — clear at small sizes, fast to generate) / Flat vector / Painted / Placeholder-only (colored rectangles).
Audio: Include sound effects + music goal (Recommended) / Skip audio entirely.
Optional goals: Any extra goals beyond the standard decomposition? (e.g., "add a tutorial level", "add screen shake effects").

Confidence check after each round

After each round: "If I started writing files now, what could go wrong?" If "not much" → proceed. If meaningful unknowns → ask one more focused round. If 3 rounds done and still under 95% → tell the user rather than guessing.

Recommendation heuristics

Area	Heuristic
Name/slug	Kebab-case from game description; short and memorable
Resolution	800x600 unless user specifies widescreen or mobile
Genre	Trust the variant mapping; ask only when ambiguous
Scope	Narrowest scope that achieves the spec. Out-of-scope wins ties
Art style	Pixel art default — fast to generate, scales cleanly
Goal count	5-7 goals; fewer for simple games, more for complex ones
Mechanics	Genre defaults first; only add mechanics the user explicitly mentions

Step 4 — Scaffold

Always scaffold. This is mandatory (unlike WP/CLI skills where it's optional). Templates live in references/scaffold-templates.md (file contents) and references/agents-template.md (AGENTS.md content). Read both when scaffolding.
