Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.00944 |
| Opus 5.5 | $0.00019 | $0.00378 |
| Sonnet 5.5 | $0.00009 | $0.00189 |
| Haiku 4.5 | $0.00005 | $0.00094 |
Grade A, and why
creature-artist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Creature Artist
Believable creature design grounded in anatomy. Movement-informed topology. Fantasy with physical plausibility.
When to Use
- Fantasy creatures, monsters, aliens
- Quadrupeds, flying creatures, aquatic forms
- Hybrid designs (part animal, part mechanical)
- Boss creatures, enemies, companions
Design Principles
- Anatomy grounding — Even fantasy references real biology
- Silhouette first — Unique readable shape
- Movement logic — Skeleton supports intended motion
- Muscle flow — Surface forms follow underlying structure
- Storytelling — Design communicates behavior (predator/prey/scavenger)
Workflow
Reference → Skeleton Blockout → Muscle Masses → Surface Forms
→ Detail (sculpt or model) → Retopology → Rig → Animation Test
Creature Types
| Type | Skeleton Base | Key Forms |
|---|---|---|
| Quadruped | Dog/horse reference | Shoulder hump, haunches |
| Biped | Human/primate | Upright spine, heel plant |
| Flying | Bat/bird | Wing membrane, keel chest |
| Aquatic | Fish/shark | Lateral line, fin placement |
| Serpentine | Snake | Ribcage segmentation |
| Insectoid | Arthropod | Segmented body, jointed legs |
Muscle Flow
- Origin → Insertion direction visible in surface
- Flexed areas: compressed forms, overlapping skin
- Extended areas: stretched, thinner surface
- Fat deposits: soft transitions (belly, cheeks)
- Scars/armor: break muscle flow intentionally
Bone Structure Planning
Before surface modeling:
- Place joint locations (spine segments, limbs)
- Verify range of motion at each joint
- Ensure limb attachment supports gait cycle
- Head/neck connection supports attack/look poses
Surface Detail Tiers
| Tier | Detail | Method |
|---|---|---|
| Primary | Overall mass | Blockout/sphere modeling |
| Secondary | Muscle groups | Sculpt or extrusion |
| Tertiary | Skin folds, veins | Sculpt |
| Micro | Scales, pores, scars | Sculpt + bake to normal |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

creature-artist is a skill published in the GitHub repository arjun988/blender-skills (735 stars, last pushed 3mo ago), licensed MIT. It adds 47 tokens to every session and 944 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

alpha-scene-gen
Generates AI 3D models through the Alpha3D MCP connector and imports them directly into the user's currently open Blender scene, scaled and placed to build out a described environment, prop set, or character roster. Use this skill whenever the user wants to populate, build, dress, furnish, or fill a Blender scene with…
blender-modeling
Create and edit 3D meshes in Blender — primitives, hard-surface modeling, mesh operators, modifier stacks (Bevel, Subdivision, Boolean, Mirror, Array, Solidify), bmesh-level edits, retopology basics. Use whenever the user asks to "make/model/create/build a 3D object", "shape/sculpt this", "add a…
reference-to-3d
Reconstruct Blender models from supplied reference sheets, branding templates, texture atlases, orthographic front/side/back/top views, or mascot/logo art where visual fidelity to the source is more important than a plausible generated object. Use when the user says the model must match a template, wireframe, texture…
blender-uv-texturing
UV unwrap, atlas-map, project textures, use alpha decals, bake maps/lightmaps, and prepare texture-driven Blender assets for glTF/GLB export. Use whenever the user provides texture packs, texture atlases, decals, UV layouts, lightmaps, wants a texture to fit a mesh 1:1, or reports stretched/off textures. Pairs with…
landmark-fit-repair
Validate and repair source-locked Blender models using named landmarks such as leaf tips, shell corners, eyes, smile, rim thickness, aura center/radius, and view-specific depth markers. Use when bbox/IoU is insufficient and the model must align to templates at designed feature points.
closed-surface-uv-coverage
Ensure textures and decals cover all visible surfaces of a closed or extruded Blender asset, especially front/back caps and sidewalls, instead of relying on partial projected planes, curves, or linework overlays. Use when back textures do not fill the model, side textures are missing, spin/turntable views expose plain…
