  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.

Workflow

Phase 1: Understand the Concept

1. **Research the topic** deeply before asking questions

• Use web search to understand the core concepts
• Identify the key insights that make this topic interesting
• Find the "aha moment" - what makes this click for learners
• Note common misconceptions to address

2. **Identify the narrative hook**

• What question does this video answer?
• Why should the viewer care?
• What's the surprising or counterintuitive element?

Phase 2: Clarify with User

Ask targeted questions (not all at once - adapt based on responses):

**Audience & Scope**

• What math/science background should I assume? (e.g., "knows calculus" or "high school algebra")
• Target video length? (short: 5-10min, medium: 15-20min, long: 30min+)
• Should this be self-contained or part of a series?

**Focus & Depth**

• Any specific aspects to emphasize or skip?
• Proof-heavy or intuition-focused?
• Real-world applications to include?

**Style Preferences**

• Color scheme preferences?
• Narration style? (casual, formal, playful)
• Any specific visual metaphors you have in mind?

Phase 3: Create scenes.md

Output a comprehensive `scenes.md` file with this structure:

# [Video Title]

## Implementation Order
[Suggested order for implementing scenes, noting dependencies]

3b1b Style Principles

Apply these principles when composing scenes:

Visual Storytelling

• **Show, don't just tell** - Every concept needs a visual representation
• **Progressive revelation** - Build complexity gradually, don't show everything at once
• **Visual continuity** - Transform objects rather than replacing them when possible

Pacing & Rhythm

• **Pause for insight** - Give viewers time to absorb key moments
• **Vary the pace** - Mix quick sequences with slower explanations
• **End scenes with resolution** - Each scene should feel complete

Mathematical Beauty

• **Emphasize elegance** - Highlight when math is surprisingly simple or beautiful
• **Connect representations** - Show the same concept multiple ways (algebraic, geometric, intuitive)
• **Embrace abstraction gradually** - Start concrete, then generalize

Engagement Techniques

• **Pose questions** - Make viewers curious before revealing answers
• **Acknowledge difficulty** - "This might seem confusing at first..."
• **Celebrate insight** - Make the "aha moment" feel earned
