Create a narrated 3Blue1Brown-style animated explainer video about how an existing project feature works, using manim with ElevenLabs or local text-to-speech. Use when the user asks for an explainer, walkthrough, or teaching video about code, architecture, or system behavior; not for promotional clips or slide decks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Explainer Video Creation Produce one narrated MP4 that teaches how a feature works. Every narrated claim must come from investigated evidence. ## Workflow ### 1.

Narrate only facts from the sheet. Leave out inconclusive facts or present them as open questions. ### 3. Choose the voice Select the first available provider: …

How to install
mdr add yarlson/yarstack/explainer-video-create@sha256:39cf6a95d8ca8b79The line at the top of this page pins the label git:20261017.2f2e03b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
