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 | $0.00017 | $0.05284 |
| Opus 5 | $0.00009 | $0.02642 |
| Sonnet 5 | $0.00003 | $0.01057 |
| Haiku 4.5 | $0.00002 | $0.00528 |
Grade A, and why
unity-material 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 3d 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 — 397 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via
GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.
Triggers
- Changing how a surface looks
- Tweaking material parameters
- Swapping shaders
- 调整物体外观、修改材质参数、切换 Shader
Unity Material Skills
BATCH-FIRST: Use
*_batchskills when operating on 2+ objects/materials.
Operating Mode
- Approval (default): all mutating skills (
material_create,material_create_batch,material_assign,material_assign_batch,material_duplicate,material_set_color/_emission/_texture/_float/_int/_vector/_keyword/_render_queue/_shader/_texture_offset/_texture_scale/_gi_flags, and the*_batchvariants) need user grant; grant triggers a single server-side execution that returns the result. - Auto / Bypass: those skills execute directly.
- Query skills (
material_get_properties,material_get_keywords) areSkillMode.SemiAuto— they run in all three modes without grant. - This module contains no Delete / PlayMode / Reload / high-risk skills (no NeverInSemi); to delete a material asset, call the
assetmodule.
Guardrails
DO NOT (common hallucinations):
material_set_metallic/material_set_smoothnessdo not exist → usematerial_set_floatwithpropertyName="_Metallic"or"_Glossiness"(Standard) /"_Smoothness"(URP)material_set_colorr/g/b/a range is 0–1, not 0–255material_set_propertydoes not exist → use the specific setter:material_set_float,material_set_int,material_set_vector,material_set_colormaterial_get_colordoes not exist → usematerial_get_properties(returns all properties including colors)
Routing:
- For shader changes →
material_set_shader(this module) - For texture tiling →
material_set_texture_scale/material_set_texture_offset - Pipeline-specific property names differ: check Render Pipeline Compatibility table in this doc
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.
- 3d ago First seen · 397 lines · 17 tokens per session scan A 4d95a852c95a
unity-material is a skill published in the GitHub repository Besty0728/Unity-Skills (1,695 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 5,284 once invoked, about $0.0001 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 2026-08-30.
