Use when a concept needs making clear rather than practising: explain simply, why does this exist, draw it, or simplify for a beginner. Not for scaffolded practice: use drill.
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
# Explain concept ## Contract | Field | Bound contract | |---|---| | Trigger | A concept needs making clear not practising; explain simply, why does this exist, draw it, what is the difference, or simplify for a beginner (ELI5). | | Authority | Read-only. No file, VCS, credential, paid, published, deployed, or remote mutation. Reading files, one web citation search for the origin angle, and a transient diagram render that leaves no artifact are the only outward operations. | | Side effect | Chat output only: a one-screen explanation for the chosen angle, one authored diagram for the picture angle, one citation search for the origin angle. Nothing is written to any file or repository. | | Done | A single-angle explanation is presented in chat, grounded in sources or with unanchored claims marked, and the user is prompted to restate or verify where the angle requires it. | ## Inputs …

How to install
mdr add outlinedriven/outline-driven-development/explain-concept@sha256:560b5b3a9f4894b1The line at the top of this page pins the label git:20260905.1f63894, 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.
