A programmable, explicit world model on Godot — worlds are pure JSON run by a fixed primitives + interpreter engine. Built by Claude, for Claude.

Convert a markdown design doc (GDD, milestone, ADR, etc.) into a self-contained HTML page. Splits into multiple pages with prev/next nav + index when the doc is long. Use whenever the user asks to "view as HTML", "convert to HTML", "render this doc", or wants a more readable / shareable format than raw markdown.

Visual + audio + UI-style designer for Yume games. Picks ONE consistent strategy per project (library lookup / AI-gen prompt / code-draw shape) for visuals; writes audio cue mappings and localized strings. Per ADR 0009 — owns audio/cues.json (semantic event → sound name) and ui/strings.json (localizable HUD text), in…
Skill Claude CodeCodex
Designer for music + soundtrack architecture across a Yume game — distinct from yume-asset-designer (which writes audio/cues.json mapping signals to one-shot SFX). This skill owns: BGM selection per screen/level/state, dynamic intensity layers (calm/explore/combat/boss), bus design (composes ADR 0013's…
Skill Claude CodeCodex
Second-pair-of-eyes for Yume engine + content changes. Socratic, principle-aligned, smell-based. Reviews diffs / files / sessions and produces a tight verdict (accept / accept-with-conditions / revise / reject). NOT the invariant gate — that's yume-tech-director. NOT a designer — those are the domain skills. This is…
Skill Claude CodeCodex
Compositional / recipe-system designer for Yume games. Translates GDD intent for crafting / alchemy / breeding / key-combos / chemistry / spell-combinations into a concrete combining-design.md — recipe table, discovery model, yield rules, failure modes, Yume primitive mapping. Universal pattern (NOT magic-specific) …
Skill Claude CodeCodex
Entities + initial state designer for Yume games. Translates GDD + world plan into entity definitions (entities/.json), initial placements (per-level entities.json), and world initial state (world/state.json). Picks tag names, state field names, default values, positions. Per ADR 0009 — narrowed scope: rules are NOT…
Skill Claude CodeCodex
One-command text-to-3D-world pipeline. From a prose scene pitch, produces a runnable Yume scene end-to-end — hero reference → hero-conditioned orthographic → semantic + heightmap → extract → map (composeworld) → presentation shell (composeshell) → optional Tripo assets. The catalog is the single LLM-authored input…
Skill Claude CodeCodex
Run the Yume text-to-game pipeline. Orchestrates 7 specialist skills (yume-game-designer → game-planner → systems-designer → content-designer → asset-designer → qa-tester, plus tech-director on demand) with optional user-approval gates. Skills load into orchestrator context (no subagent spawn — Tier 2.6 architecture).…
Skill Claude CodeCodex
Numeric balance + resource flow designer for Yume games. Reads GDD + world plan (+ optional combining-design.md) and produces economy-design.md with explicit sources/sinks per resource, conversion ratios, currency design, pricing curves, pacing math, and adversarial balance checks. Owns the question "do the numbers…
Skill Claude CodeCodex
Stage 5 of the text-to-world pipeline (2026-05-25). Reads a semantic map (PNG) + class catalog (JSON from stage 2) + optional heightmap (PNG from stage 4), and writes a per-scene Python extraction script that emits extracted.json — the sparse tile-map output containing per-class biome masks (terrainshader)…
Skill Claude CodeCodex
You are the flavor writer for Yume — the specialist for prose density. Mechanics give a game features; flavor gives it soul. You own the layer between "stat + behavior" and "named character / remembered moment / textured world.".
Skill Claude CodeCodex
First-line designer for Yume games. Takes a prose description of a game and produces a structured GDD using MDA decomposition (Mechanics → Dynamics → Aesthetics). Output feeds yume-systems-designer.
Skill Claude CodeCodex
Translates the abstract GDD (from yume-game-designer) into a concrete world bible — named NPCs with schedules, named items with purposes, named plants with growth properties, named events with triggers, town layout. Bridges design philosophy and content authoring.
Skill Claude CodeCodex
Adversarial reviewer for Yume GDDs. Reads docs/games/ /GDD.md and applies critical-but-fair scrutiny across 15 depth axes (mechanical/strategic/pacing/feedback/aesthetic/scope/adversarial + total content scope, signature moments, theme/identity, replay value, real-UX, spatial-design/level-layout). Outputs review.md…
Skill Claude CodeCodex
Goal-condition + flow-progression designer for Yume games. Per ADR 0009 revision (2026-05-16), scope NARROWED — rule authoring (scoring + transitions + objectives + tutorial overlays) folded into yume-systems-designer (writes world/rules/.json). This skill now owns (a) declarative win:/lose: blocks in hud.json that…
Skill Claude CodeCodex
You are the GDD coverage tracker for Yume — the gauge that measures how much of a GDD is actually built. Without you, autonomous runs declare "complete" when correctness tests pass; you turn that into a real coverage metric: "X% of the GDD's promises are wired and reachable.".
Skill Claude CodeCodex
Fit-fit HUD authoring from a wireframe image. Reads the per-game context from tools/visuallayout/wireframetohud.py preprocess (binding manifest + element catalog + viewport + scale factors + anchor geometry formulas) AND the wireframe PNG directly via vision, then authors a hud.json where every panel's geometry is…
Skill Claude CodeCodex
Designer for "game feel" — the polish layer of particles, screen shake, hit-pause, flash, camera kicks, and timing curves that make actions feel impactful. Distinct from yume-asset-designer (which picks visuals) and yume-visual-designer (which judges aesthetics) — this skill owns the kinetic micro-feedback per…
Skill Claude CodeCodex
Spatial layout designer for Yume games. Reads GDD + world plan, produces level-design.md with concrete coordinates for every placement plus a design rationale per element. Genre-aware patterns (TD paths with chokepoints, shooter arenas with cover, sim zones with density falloff). Output is the single source of truth…
Skill Claude CodeCodex
You are the lighting designer for Yume — the specialist for the lighting block in scene.json (per ADR 0025: declarative day/night).
Skill Claude CodeCodex
Fit-fit LEVEL/MAP authoring from a semantic top-down map image. Third sibling of yume-hud-author / yume-screen-author. Reads the per-game context from tools/visuallayout/wireframetomap.py preprocess (entity catalog with tags + assetresolution anchor/zone hints + scatterpresets + world bounds + pixel→world coord…
Skill Claude CodeCodex
Genre-specific GDD writer for merchant / shopkeeping / item-shop games. Extends yume-game-designer's generic MDA framework with merchant-required sections — adventurer-class table (≥3 classes × ≥3 gear types each), daily cycle phase table (morning/adventure/shop/sleep durations + transitions), haggle mechanic spec…
Skill Claude CodeCodex
Genre-specific reviewer for merchant / shopkeeping / item-shop GDDs. Strictest layer — runs AFTER yume-game-reviewer's generic 15-axis accept, applies 8 merchant-specific axes that catch genre concerns the generic reviewer can't see (customer-archetype variety, class-gear coverage, daily-cycle pacing balance, haggle…
Skill Claude CodeCodex
You are the playtest harness for Yume — the gate that turns "tests passed" into "actually plays end-to-end." Headless unit tests + scenario tests don't fire onclick chains, can't see render bugs, and can't catch dangling screen references that warn at runtime instead of erroring. You catch those.
