## What it does

This skill establishes a strict process for Vesperfall catalog additions. First, the agent inspects existing files. You cannot treat an asset as present just because code references a planned URL. Catalog references are standardized as 512×512 RGBA transparent images under `public/asset-catalog/<category>/` without baked shadows. In the grid view, cards show no canvas.

The selected inspector displays a single canvas running a Three.js module. Metadata covering asset paths and equipment sockets is stored in `userData`. Grounding is aligned to foot contact geometry rather than dangling weapon edges. When animations shift contact points, tests must verify grounding deterministically.

Before committing, the skill runs `scripts/validate_pair.py <png> <model-source>`. Visual validation is restricted to the Codex in-app browser. It checks both mobile and desktop views, confirming that cards have no canvas and no console errors occur.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-vesperfall-review-assets -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/build-vesperfall-review-assets/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/build-vesperfall-review-assets/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-vesperfall-review-assets -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/build-vesperfall-review-assets/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-vesperfall-review-assets -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/build-vesperfall-review-assets/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MengTo/Skills build-vesperfall-review-assets
```

2. **Manually: put the files in place**
- File: `.github/skills/build-vesperfall-review-assets/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-vesperfall-review-assets -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MengTo/Skills --path agent-skills/game-development/build-vesperfall-review-assets
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/build-vesperfall-review-assets/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill build-vesperfall-review-assets -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/MengTo/Skills/tree/HEAD/agent-skills/game-development/build-vesperfall-review-assets/SKILL.md

## When to use it
- pair transparent catalog PNGs with live Three.js or FBX models
- expose an isolated review route for character animation clips
- attach equipment items to named model sockets
- validate asset pairs deterministically with `scripts/validate_pair.py`

## Example prompts
- Build a transparent PNG card and FBX model pair for the new enemy in Vesperfall.
- Set up an isolated route to review character animations and check foot grounding.
- Run `scripts/validate_pair.py` to verify the asset pair before committing.

# Build Vesperfall Review Assets

Create one reviewable asset pair without confusing catalog media, imported files, procedural factories, and future contracts.

## Workflow

1. Inspect repository truth before choosing a model path.
   - Locate shipped PNG, FBX, GLB, textures, runtime factories, and declared-but-missing paths.
   - Prefer a shipped FBX/GLB when it is the actual runtime source.
   - Use `$img2threejs` only when reconstructing from an image in code. Never relabel imported geometry as img2threejs.
   - Do not claim a GLB or texture exists because code declares a future URL.
2. Produce the transparent catalog reference.
   - Reuse or derive from the production portrait when it already matches the asset identity.
   - Normalize catalog copies to 512×512 RGBA unless the project contract says otherwise.
   - Keep transparent corners and avoid baked floor, halo, or shadow.
   - Store project-bound output under `public/asset-catalog/<category>/`.
3. Build the live model preview.
   - Put loading/model construction in a small asset-specific module.
   - Preserve runtime provenance in `userData`: source paths or factory, action count, sockets, and review-only status.
   - Attach equipment to named sockets. Keep materials, renderer, mixers, events, and animation frames disposable.
   - Frame from measured bounds. Ground from foot/contact geometry, not the lowest weapon tip.
4. Pair the catalog surfaces.
   - Card/grid: transparent PNG only, with no canvas.
   - Selected inspector: one live model canvas plus truthful format label.
   - Add a button to an isolated preview or moveset route.
   - Keep fallback media visible until WebGL/model loading is ready.
5. Build the isolated review route.
   - Expose the real action library when clips exist.
   - Provide restart, pause/play, action selection, drag rotation, source paths, and provenance.
   - For procedural motions, mark runtime, contract, and candidate actions separately.
6. Validate before committing.
