Agent skill
manimce-best-practices
Trigger when: (1) User mentions "manim" or "Manim Community" or "ManimCE", (2) Code contains `from manim import *`, (3) User runs `manim` CLI commands, (4) Working with Scene, MathTex, Create(), or ManimCE-specific classes. Best practices for Manim Community Edition - the community-maintained Python animation engine. Covers Scene structure, animations, LaTeX/MathTex, 3D with ThreeDScene, camera control, styling, and CLI usage. NOT for ManimGL/3b1b version (which uses `manimlib` imports and `manimgl` CLI).

Quick Reference
Basic Scene Structure
from manim import *
class MyScene(Scene):
def construct(self):
# Create mobjects
circle = Circle()
# Add to scene (static)
self.add(circle)
# Or animate
self.play(Create(circle))
# Wait
self.wait(1)
Render Command
# Basic render with preview
manim -pql scene.py MyScene
# Quality flags: -ql (low), -qm (medium), -qh (high), -qk (4k)
manim -pqh scene.py MyScene
Key Differences from 3b1b/ManimGL
| Feature | Manim Community | 3b1b/ManimGL |
|---|---|---|
| Import | from manim import * |
from manimlib import * |
| CLI | manim |
manimgl |
| Math text | MathTex(r"\pi") |
Tex(R"\pi") |
| Scene | Scene |
InteractiveScene |
| Package | manim (PyPI) |
manimgl (PyPI) |
Jupyter Notebook Support
Use the %%manim cell magic:
%%manim -qm MyScene
class MyScene(Scene):
def construct(self):
self.play(Create(Circle()))
Common Pitfalls to Avoid
- Version confusion - Ensure you're using
manim(Community), notmanimgl(3b1b version) - Check imports -
from manim import *is ManimCE;from manimlib import *is ManimGL - Outdated tutorials - Video tutorials may be outdated; prefer official documentation
- manimpango issues - If text rendering fails, check manimpango installation requirements
- PATH issues (Windows) - If
manimcommand not found, usepython -m manimor check PATH
Installation
# Install Manim Community
pip install manim
# Check installation
manim checkhealth
Useful Commands
manim -pql scene.py Scene # Preview low quality (development)
manim -pqh scene.py Scene # Preview high quality
manim --format gif scene.py # Output as GIF
manim checkhealth # Verify installation
manim plugins -l # List plugins
Recommended Agent Skills
Expand your agent's capabilities with these related and highly-rated skills.
manim-composer
Trigger when: (1) User wants to create an educational/explainer video, (2) User has a vague concept they want visualized, (3) User mentions "3b1b style" or "explain like 3Blue1Brown", (4) User wants to plan a Manim video or animation sequence, (5) User asks to "compose" or "plan" a math/science visualization. Transforms vague video ideas into detailed scene-by-scene plans (scenes.md). Conducts research, asks clarifying questions about audience/scope/focus, and outputs comprehensive scene specifications ready for implementation with ManimCE or ManimGL. Use this BEFORE writing any Manim code. This skill plans the video; use manimce-best-practices or manimgl-best-practices for implementation.
manimgl-best-practices
Trigger when: (1) User mentions "manimgl" or "ManimGL" or "3b1b manim", (2) Code contains `from manimlib import *`, (3) User runs `manimgl` CLI commands, (4) Working with InteractiveScene, self.frame, self.embed(), ShowCreation(), or ManimGL-specific patterns. Best practices for ManimGL (Grant Sanderson's 3Blue1Brown version) - OpenGL-based animation engine with interactive development. Covers InteractiveScene, Tex with t2c, camera frame control, interactive mode (-se flag), 3D rendering, and checkpoint_paste() workflow. NOT for Manim Community Edition (which uses `manim` imports and `manim` CLI).
migrate-to-skills
discover-assumptions
Use after solution concepts exist to surface and prioritize assumptions behind outcomes, opportunities, or solution ideas and design experiments to test them.
discover-opportunities
Use after outcomes are defined to discover opportunities, unmet needs, market gaps, or JTBD insights before choosing solutions.
discover-outcomes
Use at the start of product strategy to define or refine desired outcomes and success metrics (e.g., for Opportunity Solution Trees or continuous discovery) before selecting opportunities or solutions.
