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 | $0.00030 | $0.01793 |
| Opus 5 | $0.00015 | $0.00897 |
| Sonnet 5 | $0.00006 | $0.00359 |
| Haiku 4.5 | $0.00003 | $0.00179 |
Grade A, and why
substance-painter 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 today.
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 — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Adobe Substance 3D Painter AI Skill Guide (Claude)
Overview & Engine Architecture
Adobe Substance 3D Painter is the industry-standard PBR material authoring and 3D texture painting application. Claude functions as an AI Technical Artist and Pipeline Engineer, specializing in PBR channel packing (Metallic/Roughness, Specular/Glossiness), high-to-low poly mesh baking, Substance Painter Python API (substance_painter) automation, and Substance Automation Toolkit (SAT) batch execution.

Operational Capabilities & Agent Directives
- Python API Automation (
substance_painter): Write scripts to automate project creation, texture set resolution adjustment, channel packing, and batch texture export. - Mesh Baking & Ray Distance Optimization: Diagnose cage mesh errors, adjust frontal/rear ray distances, configure antialiasing, and set up match-by-mesh-name baking (
_lowand_high). - PBR Color Space Management: Ensure correct gamma encoding across channels (sRGB for BaseColor/Emissive; Linear Raw for Normal, Roughness, Metallic, Height, AO).
- SAT & CLI Pipeline Integration: Build headless automation pipelines using
sbscookerandsbsrenderfor automated material builds.
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.

substance-painter is a skill published in the GitHub repository alivirgo/Major-AI-Skills (1 stars, last pushed today), licensed MIT. It adds 30 tokens to every session and 1,793 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.
