Create a simple, picture-first explanation of a topic, defaulting to self-contained HTML. Use when the user says ELI5, asks to explain something like they are five, or wants a visual explanation with very few words; do not use for ordinary concise explanations that do not ask for this style.
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
# ELI5
Explain the topic from the user's request as if the reader knows nothing about it.
By default, create one self-contained HTML artifact with big visuals and very few words. Prefer a simple diagram, pictograms, arrows, labels, and one concrete example over paragraphs of explanation. If the user requests another medium, honor it and adapt the explanation to what that medium supports.
## Outcome
The reader should be able to glance at the artifact and understand:
- what the thing is
- how its main parts or steps relate
- one useful mental model or everyday analogy
- the single most important takeaway
## Rules
- Use plain, respectful language. Simplify the topic, not the reader.
- Lead with the visual explanation; keep supporting text short.
- Focus on one core idea. Omit secondary details unless they prevent a false understanding.
- Use familiar examples and define unavoidable technical terms in place.
- When using an analogy, explicitly connect its familiar objects or actions to the real concepts. Briefly label where the analogy stops matching reality when that boundary matters.

The line at the top of this page pins the label git:20260908.1c9156a, 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.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
