# Manim Video Use this skill for Python-based Manim projects that need a clean planning phase, strong visual direction, reusable scene structure, and a deterministic render pipeline. The output contract is usually a workspace project directory containing `plan.md`, `script.py`, `concat.txt`, draft renders, and optionally a stitched `final.mp4`. ## Creative Standard This is educational cinema, not animated slides. - Make it beautiful and professional. The draft should feel intentional, polished, and presentation-ready, not like a rough internal diagram dump. - Before writing code, define the narrative arc: confusion -> visual hook -> mechanism -> payoff -> recap. - Geometry before algebra. Show the shape, motion, system flow, or data change before the formal equation. - Every scene teaches one dominant idea. If a scene has two unrelated claims, split it. - Direct attention with opacity layering: primary elements at 1.0, contextual elements around 0.35-0.45, and structural elements like axes or grids around 0.12-0.2. - Give reveals breathing room. Add `self.wait()` after every important animation and make the main aha moment the longest pause. - Keep one cohesive visual language across the whole project: shared palette, shared timing constants, shared font rules, and stable concept-color meaning. - Avoid repetitive scenes. Vary dominant color, layout, and entry animation across scenes while keeping the overall palette consistent. - First-render quality matters. If the layo...
