blender-geometry-nodes

blender-geometry-nodes is a skill for Claude Code from ra100/blender-claude-plugin. It costs 68 tokens per session (3,073 once invoked), scanned A, original, MIT.

Guidance for Blender 5.x Geometry Nodes, Blender's visual system for creating procedural 3D models and effects from connected operations. It also covers building node trees with Blender's Python API.

In plain words
What is it for?
Use it to create scattering and procedural models, work with meshes, curves, volumes, simulations, and repeat zones, or automate node-tree construction and inspection.
Why use it?
It helps explain the large and changing set of Geometry Nodes, diagnose slow setups, and inspect or modify a live Blender scene. A connected Blender tool can run changes directly; otherwise it can produce Python scripts.

Token cost

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.

Security

Grade A, and why

blender-geometry-nodes 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 10d 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.

Blender Geometry Nodes Expert

Overview

This skill provides expert guidance for Blender 5.x geometry nodes: designing node setups, writing Python scripts to build node trees programmatically, debugging performance issues, and understanding the complete node catalog. The reference files contain the full node listing and Python API patterns.

MCP-First Approach

Prefer the official Blender MCP Server (Blender Lab, Blender 5.1+) for creating node groups, wiring fields, scattering instances, reading outputs directly in a running Blender session. Fall back to emitting Python scripts only when the MCP server is not connected.

Detection: at session start, look for tools whose names match execute_blender_code, get_objects_summary, or search_api_docs — these belong to the official blender-mcp server. If any are present, MCP is available.

Tools used by this skill:

  • execute_blender_code — run bpy Python in the live session (primary action)
  • get_objects_summary, get_object_detail_summary — inspect scene state before mutating
  • get_blendfile_summary_datablocks / _missing_files / _of_linked_libraries / _path_info / _usage_guess — inventory the file
  • search_api_docs, get_python_api_docs, search_manual_docs — confirm correct API/operator names before calling them
  • get_screenshot_of_window_as_image / _as_json, get_screenshot_of_area_as_image — verify visual results
  • jump_to_tab_by_name, jump_to_tab_by_space_type, jump_to_view3d_object_by_name, jump_to_view3d_object_data_by_name — drive the UI to make changes visible
  • render_thumbnail_to_path, render_viewport_to_path — capture quick visual feedback

Workflow: inspect with a get_* / search_* tool → mutate via execute_blender_code → verify with a screenshot or summary tool. Keep code blocks small and idempotent so failures are easy to localize.

Setup: see docs/blender-mcp-setup.md.

Task Decision Tree

  • "Create a geometry node setup for X" -> Design the node tree, then generate Python code to build it (see Generating Node Trees)
  • "My geometry nodes are slow" -> Follow the Debugging & Optimization workflow
  • "What node does X?" -> Consult references/node_reference.md for the complete node catalog
  • "How do I connect X to Y?" -> Check socket compatibility and suggest the correct node chain
  • "Script a geometry node tree" -> Consult references/python_api.md for API patterns

Changes

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-geometry-nodes is a skill published in the GitHub repository ra100/blender-claude-plugin (14 stars, last pushed 4mo ago), licensed MIT. It adds 68 tokens to every session and 3,073 once invoked, about $0.0003 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.
