Manim Video Composer

What it does

When your agent uses it

• Planning a 3Blue1Brown-style math or science explainer
• Turning a vague concept into a scene-by-scene outline
• Deciding audience, length and focus before animating

Example prompts

• “Plan a 3b1b-style video explaining why the sum of the first n odd numbers is a perfect square.”
• “I want a video about Fourier series. Ask me what you need and write scenes.md.”
• “Compose a medium-length explainer on eigenvalues for people who know basic linear algebra.”

Requirements

• Web search, for researching the topic

Workflow steps

3 steps, taken from the step headings in SKILL.md.

1. 1Understand the Concept
2. 2Clarify with User
3. 3Create scenes.md

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

  No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

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

• Network

  No URLs in SKILL.md.

  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

Manim Video Composer loads about 1.2k tokens when it runs, and up to ~4.8k if it reads all its reference files. Until then it costs about 179 tokens; SKILL.md has 309 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~179

When it runs · the whole SKILL.md, loaded when a task matches

~1.2k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~4.8k

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

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.

description

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.
