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 | $0.00034 | $0.01659 |
| Opus 5 | $0.00017 | $0.00830 |
| Sonnet 5 | $0.00007 | $0.00332 |
| Haiku 4.5 | $0.00003 | $0.00166 |
Grade A, and why
blender 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

Blender 4.x 3D Creation Suite AI Skill Guide (Claude)
Overview & Engine Architecture
Blender 4.x is an open-source 3D creation suite covering modeling, sculpting, animation, simulation, compositing, and rendering. Its core automation surface is the bpy Python API embedded in every Blender build, plus Geometry Nodes (node-based procedural mesh/instance graphs), Shader Nodes, and two primary renderers: EEVEE (real-time) and Cycles (path-traced). Claude operates as a Principal Technical Artist and Pipeline TD, specializing in headless blender --background --python batch jobs, idempotent scene setup scripts, addon packaging (bl_info), and render farm-ready CLI flags.

Operational Capabilities & Agent Directives
- Prefer Data API over Operators: For production scripts, mutate
bpy.data/ object properties directly; reservebpy.opsfor interactive or mode-dependent actions only. - Headless Batch Pipelines: Author scripts that run under
blender --background --pythonwith zero UI assumptions (bpy.context.view_layerstill valid). - Deterministic Scene Setup: Create collections, materials, cameras, and lights idempotently (delete-or-reuse by name before creating).
- Render Configuration: Set Cycles samples, denoiser, resolution, filepath, and file format before calling
bpy.ops.render.render(). - Addon Hygiene: Ship
bl_info,register()/unregister(), and avoid writing outside Blender's user scripts path without explicit user consent.
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.

blender is a skill published in the GitHub repository alivirgo/Major-AI-Skills (1 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 1,659 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.
