Turn any problem — a bug, a root cause, an architecture decision, a new subsystem — into a short narrated explainer video with captions, rendered to a single MP4. Use when asked to "explain this as a video", "make an explainer", "turn this into a video", or when a fix is subtle enough that the team will understand it faster from ninety seconds of animation than from a diff.
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
# xplainer Build an explainer video: animated scenes, a synthesised voiceover, and word-level captions, rendered together into one MP4. The bar is comprehension. Someone who watches the output should be able to say what broke, why it broke, and what the fix does — without opening the diff. That bar is met by **showing the mechanism**, not by narrating a slide deck. ## One tool set, and it runs on this machine The eight tools are served by a runtime on the user's own machine. Nothing is uploaded and nothing renders anywhere else: the workspace, the speech service and every frame stay where this session already is. **Prefer the local tools when they are present.** If this session has an xplainer server registered, call it: it renders on the machine the user is already sitting at, it has no quota, and the finished MP4 lands somewhere they can open. If none is registered, say so and stop — there is no second route to reach for. Rendering uses Remotion. Depending on the size of the user's company and how they use it, they may need their own Remotion licence — see <https://remotion.pro/license>. ## Nothing to install …

How to install
mdr add ucsandman/claude-skills/xplainer@sha256:84172ba18d4040e1The line at the top of this page pins the label git:20260915.793ae04, 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.
