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.

Apply these principles when composing scenes:
development
Use when searching the web or reading online documentation. Prefer DuckDuckGo for search and read documents through npx curl.md instead of raw HTML.
testing
Use when writing or editing tests. Tests should be ordered by near-normal, normal, then abnormal cases where applicable, and test names must be Japanese behavior descriptions from a reviewer/user perspective.
development
GoF/オブジェクト指向デザインパターンを関数型プログラミング(pure functions, higher-order functions, ADT, composition, immutability, effect boundaries)でシンプルに整理・設計・リファクタリングする。Strategy/Factory/Adapter/ObserverなどGoF全23パターンのFP置き換え、適用判断、具体事例を提示する必要があるときに使う。
tools
Use when committing, pushing, or preparing PRs. Defines the user's commit workflow, message style discovery, review handoff, and branch/worktree push requirements.
