\# Blender Animation Skill#

\## Purpose#

This skill enables automated 3D animation generation using Blender in headless mode. It is designed for controlled, programmatic scene creation and rendering workflows in server or agent environments.#

---#

\## When to use#

Use this skill when:#

- Generating 3D animations programmatically#

- Creating motion graphics using Blender#

- Rendering animation output without GUI#

- Automating scene setup, lighting, and camera movement#

Do NOT use this skill for:#

- Arbitrary system command execution#

- File system exploration outside task scope#

- Network-based operations unless explicitly required#

---#

\## Capabilities#

- Scene creation using Blender Python (bpy)#

- Object animation and transformations#

- Camera setup and motion#

- Lighting configuration#

- Rendering animation to MP4 format#

- Headless execution (no GUI)#

---#

\## Execution Model#

1. Generate a Blender Python script#

2. Save script to:#

/tmp/blender_script.py#

3. Execute Blender in headless mode using:#

scripts/run_blender.sh#

4. Output is saved to:#

/tmp/output.mp4#

---#

\## Safety & Constraints#

- Execution is limited to Blender-related operations only#

- No arbitrary shell commands outside the defined script runner#

- No modification of system files outside /tmp#

- No access to sensitive directories (e.g., /etc, /home)#

- Network access should not be used unless explicitly required#

- Scripts must only perform scene creation and animation tasks#

- Avoid large resource usage (default animation limit: 10 seconds)#

---#

\## Sandbox Expectation#

This skill is intended to run in a controlled or sandboxed environment such as:#

- Containerized execution (Docker)#

- Restricted agent runtime#

- Limited-permission server environment#

---#

\## Rules#

- Always run Blender in headless mode#

- Never open GUI#

- Always generate a Python script before execution#

- Keep animations under 10 seconds unless specified#

- Always return output file path and logs#

---#

\## Output#

Return:#

- Rendered video file (/tmp/output.mp4)#

- Blender Python script used#

- Execution logs#

---#

\## Transparency Notice#

This skill executes generated Python scripts within Blender.#

Users should review generated scripts if operating in sensitive environments.#
