Blender Agent Skills
Professional Blender 5.2 workflows as Agent Skills: modelling, UVs, PBR, baking, rigging, animation, export and QA.
Listed from the author's README. GameSkill has not run this end to end yet. Agent support and install steps are as documented by the author.
Install
npx skills add EL4CTEO/blender-skills --skill blender-core blender-addon-developmentInstalls this skill plus blender-core, which every Blender skill in this pack builds on. Add -a claude-code (puts it in .claude/skills/), -a codex or -a cursor (.agents/skills/) to choose the agent, and -g to install it for your user instead of the project.
Commands are copied from the project's README. Check the repository before running anything on your machine.
Install for a specific agent
| Agents | -a | Folder |
|---|---|---|
| Claude Code | claude-code | .claude/skills/ |
| Codex | codex | .agents/skills/ |
| Cursor | cursor | .agents/skills/ |
| Gemini CLI | gemini-cli | .agents/skills/ |
| GitHub Copilot | github-copilot | .agents/skills/ |
| OpenCode | opencode | .agents/skills/ |
| Windsurf | windsurf | .windsurf/skills/ |
Add -a <flag> to the command. These are project folders; add -g to install for your user account instead.
What you get
- A pitfalls section with the mistakes to avoid
- Bundled 4 assets the agent reads when needed
- Written for Blender 5.2

Write a Blender 5.2 add-on that batch-renames and exports the selected meshes.About this skill
Write Blender 5.2 add-ons as extensions - blender_manifest.toml, operators/panels/menus/property groups/preferences, bpy.props rules after 5.0, undo/redo, modal and timer patterns, gpu drawing (no bgl), bundling Python wheels, CLI validate/build/install, testing headless, extensions platform publishing. Use when creating or fixing a Blender add-on, tool, or UI.

Good to know
Every skill in Blender Agent Skills builds on blender-core, which runs Python in Blender (live through MCP, or headless) and routes tasks. Install the two together.
Requirements
- Blender 5.2
- Blender 5.2+
- The blender-core skill from the same pack
- Optional: a Blender MCP server for live control
