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.

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 | $0.00039 | $0.01785 |
| Opus 5 | $0.00019 | $0.00892 |
| Sonnet 5 | $0.00008 | $0.00357 |
| Haiku 4.5 | $0.00004 | $0.00178 |
Grade A, and why
unity-probuilder 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 7d 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.

Unity ProBuilder Skills
Requirements
com.unity.probuilder(≥ 6.0). If missing, install viaUnity_PackageManager_ExecuteActionwithoperation=Add,package=com.unity.probuilder,version=6.0.9.
When to Use
Use this module for editable ProBuilder meshes, not regular primitive GameObjects. It is best for blockout, level geometry, and procedural mesh refinement.
Batch-first: For scene blockout or level generation, prefer
probuilder_create_batchwhen creating2+shapes.
Common Mistakes
DO NOT (common hallucinations):
probuilder_create_meshdoes not exist -> useprobuilder_create_shapeprobuilder_edit_facedoes not exist -> use the specific face skills such asprobuilder_extrude_faces,probuilder_delete_faces,probuilder_merge_facesprobuilder_set_materialandprobuilder_set_face_materialare different -> whole object vs selected faces- Regular meshes do not become ProBuilder meshes automatically
- Mesh rebuild calls (
ToMesh()+Refresh()) are already handled by the skills. Do not invent a manual rebuild step
Routing:
- For ordinary primitive objects without editable topology -> use
gameobject_create - For material asset creation or shader work -> use
material - For large blockout generation -> combine this module with
materialandlight, but keep geometry creation here
Object Targeting
Most edit/query skills accept one of:
nameinstanceIdpath
Prefer instanceId when multiple scene objects share the same name.
Quick Reference
Create and Batch
| Skill | Use | Key parameters |
|---|---|---|
probuilder_create_shape |
Create a parametric ProBuilder shape | shape, name?, x/y/z?, sizeX/Y/Z?, rotX/Y/Z? |
probuilder_create_batch |
Create multiple shapes in one call | items, defaultParent? |
Supported shape values: Cube, Sphere, Cylinder, Cone, Torus, Prism, Arch, Pipe, Stairs, Door, Plane.

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.

unity-probuilder is a skill published in the GitHub repository batihandev/unity-mcp-skills (6 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 1,785 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
