+name: manim-video
+description: Build reusable Manim explainers for technical concepts, graphs, system diagrams, and product walkthroughs, then hand off to the wider ECC video stack if needed. Use when the user wants a clean animated explainer rather than a generic talking-head script.
+origin: ECC

+
+# Manim Video
+
+Use Manim for technical explainers where motion, structure, and clarity matter more than photorealism.
+
+## When to Activate
+
+- the user wants a technical explainer animation
+- the concept is a graph, workflow, architecture, metric progression, or system diagram
+- the user wants a short product or launch explainer for X or a landing page
+- the visual should feel precise instead of generically cinematic
+
+## Tool Requirements
+
+- `manim` CLI for scene rendering
+- `ffmpeg` for post-processing if needed
+- `video-editing` for final assembly or polish
+- `remotion-video-creation` when the final package needs composited UI, captions, or additional motion layers
+
+## Default Output
+
+- short 16:9 MP4
+- one thumbnail or poster frame
+- storyboard plus scene plan
+
+## Workflow
+
+1. Define the core visual thesis in one sentence.
+2. Break the concept into 3 to 6 scenes.
+3. Decide what each scene proves.
+4. Write the scene outline before writing Manim code.
+5. Render the smallest working version first.
+6. Tighten typography, spacing, color, and pacing after the render works.
+7. Hand off to the wider video stack only if it adds value.
+
+## Scene Planning Rules
+
+- each scene should prove one thing
+- avoid overstuffed diagrams
+- prefer progressive reveal over full-screen clutter
+- use motion to explain state change, not just to keep the screen busy
+- title cards should be short and loaded with meaning
+
+## Network Graph Default
+
+For social-graph and network-optimization explainers:
+
+- show the current graph before showing the optimized graph
+- distinguish low-signal follow clutter from high-signal bridges
+- highlight warm-path nodes and target clusters
+- if useful, add a final scene showing the self-improvement lineage that informed the skill
+
+## Render Conventions
+
+- default to 16:9 landscape unless the user asks for vertical
+- start with a low-quality smoke test render
+- only push to higher quality after composition and timing are stable
+- export one clean thumbnail frame that reads at social size
+
+## Reusable Starter
+
+Use [assets/network_graph_scene.py](assets/network_graph_scene.py) as a starting point for network-graph explainers.
+
+Example smoke test:
+
+```bash
+manim -ql assets/network_graph_scene.py NetworkGraphExplainer
+```
+
+## Output Format
+
+Return:
+
+- core visual thesis
+- storyboard
+- scene outline
+- render plan
+- any follow-on polish recommendations
+
+## Related Skills
+
+- `video-editing` for final polish
+- `remotion-video-creation` for motion-heavy post-processing or compositing
+- `content-engine` when the animation is part of a broader launch
