At a glance

Collects best-practice rules and tested example scripts for ManimGL, the 3Blue1Brown OpenGL animation engine, covering scenes, mobjects, Tex rendering, 3D and interactive mode.

  • Works in 6 steps: Version confusion - Ensure you're using… → ShowCreation vs Create - ManimGL uses… → Tex vs MathTex - ManimGL uses Tex with… → …
  • Writing or debugging a ManimGL animation script
  • SKILL.md covers How to use, Working Examples, Scene Templates and Quick Reference, plus 1 more section
  • Runs Python scripts from its folder; calls pip

What it does

The skill is a set of rule files and example Python scripts for ManimGL specifically, the from manimlib import * version used for 3Blue1Brown-style animations, not Manim Community Edition. Rule files cover core concepts such as InteractiveScene and mobject types, creation and transform animations like ShowCreation and TransformMatchingTex, text and math rendering with Tex and tex_to_color_map, styling such as fill, stroke and GLSL coloring, 3D objects and camera control with frame.reorient, and interactive development using the -se flag and checkpoint_paste.

It triggers when manimgl or 3b1b manim is mentioned, when code imports from manimlib, when manimgl CLI commands run, or when patterns like InteractiveScene, self.frame or self.embed() appear. Working example files cover basic animations, LaTeX-heavy math visualization, graphing with Axes, and 3D scenes with camera control, and the licence is CC-BY-NC-4.0, which restricts commercial use.

When your agent uses it

  • Writing or debugging a ManimGL animation script
  • Adding 3D surfaces, camera moves or interactive debugging to a Manim scene
  • Rendering LaTeX equations or colored math expressions in an animation
  • Migrating or distinguishing ManimGL code from Manim Community Edition

Example prompts

  • “Write a ManimGL scene that rotates a 3D torus while a LaTeX equation fades in.”
  • “Use checkpoint_paste to debug this ManimGL animation interactively.”
  • “Color the matrix terms in this Tex expression using tex_to_color_map.”

Requirements

  • ManimGL (the from manimlib import * package)
  • A LaTeX installation for Tex rendering

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Version confusion - Ensure you're using manimgl, not manim (community version)
  2. ShowCreation vs Create - ManimGL uses ShowCreation, not Create
  3. Tex vs MathTex - ManimGL uses Tex with capital R raw strings
  4. self.frame vs self.camera.frame - ManimGL uses self.frame directly
  5. fix_in_frame() - Call on the mobject, not the scene
  6. Interactive mode - Use -se flag for interactive development

What it can do on your machine

Read from SKILL.md and the folder at commit cef0450. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Python, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • creativecommons.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

ManimGL Best Practices loads about 1.9k tokens when it runs, and up to ~7.5k if it reads all its reference files. Until then it costs about 157 tokens; SKILL.md has 412 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~157
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (CC-BY-NC-4.0) doesn't allow us to republish the file, so here is its outline and opening line. It has 412 words (~1,860 tokens).
