What it does

Build Vesperfall Review Assets is an agent skill from nirholas/three.ws. Build truthful Vesperfall asset-library review pairs from transparent PNG references and live Three.js, FBX, or img2threejs models. Use when adding a character, enemy, prop, or equipment asset to the Vesperfall catalog; creating a card-PNG plus inspector-model treatment; exposing an isolated model or moveset route; or standardizing provenance, grounding, tests, and Codex-browser validation for game art review.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/catalog-contract.md` and `scripts/validate_pair.py`).

It sits in Game Development, covering 3D graphics and WebGL, Sprites and pixel art and Game development. It works with Three.js. The repository describes itself as: Open-source platform for 3D AI agents. Turn text or a photo into a rigged, animated GLB avatar, give it an LLM brain, memory and a wallet, and embed it anywhere with one web… The licence is Apache-2.0.

When your agent uses it

  • Adding a character
  • Equipment asset to the Vesperfall catalog
  • Creating a card-PNG plus inspector-model treatment
  • Exposing an isolated model

Example prompts

  • “/build-vesperfall-review-assets”

Requirements

  • Python 3

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Inspect repository truth before choosing a model path.
  2. Produce the transparent catalog reference.
  3. Build the live model preview.
  4. Pair the catalog surfaces.
  5. Build the isolated review route.
  6. Validate before committing.
  7. Commit the narrow task and hand off its exact SHA before deployment reconciliation.

What it can do on your machine

Read from SKILL.md and the folder at commit 66624fb. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Build Vesperfall Review Assets loads about 870 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 111 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~111
When it runs · the whole SKILL.md, loaded when a task matches
~870
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Build truthful Vesperfall asset-library review pairs from transparent PNG references and live Three.js, FBX, or img2threejs models. Use when adding a character, enemy, prop, or equipment asset to the Vesperfall catalog; creating a card-PNG plus inspector-model treatment; exposing an isolated model or moveset route; or standardizing provenance, grounding, tests, and Codex-browser validation for game art review.

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.
    • Run scripts/validate_pair.py <png> <model-source>.
    • Add inventory tests for exact paths, RGBA dimensions, preview kind, and route.
    • Test every motion/contact point deterministically when grounding changes with animation.
    • Run build, lint, full tests, and git diff --check.
    • Use the Codex in-app browser only. Verify desktop and mobile, card PNG/no canvas, inspector model/one canvas, preview navigation, grounding, scroll, overflow, broken media, and console warnings/errors.
  7. Commit the narrow task and hand off its exact SHA before deployment reconciliation.

Required reporting

Report:

  • PNG path, dimensions, and alpha status
  • model source or procedural factory
  • whether the model is imported, runtime procedural, or review-only reconstruction
  • preview route and available actions
  • test/build/browser proof
  • exact commit SHA
