Explain something on request, at three depths. Use when the user writes "???" (full: What, Why, Example, Consequences), "??" (medium: the same four parts, each short) or "?" (short: two or three bullets) - alone (the last discussed point) at the end of any message ("the audit gate ??", "is xyz so bad?") or inside it, where each marker applies to the part right before it ("what about xyz ?? and explain zxy ???"). The longest ending wins ("???" before "??" before "?"), and a normal question…
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 in Depth Give a thorough, structured explanation of a subject the user wants to understand better. The subject is whatever the user pointed at: a reference, a statement, or a term. This skill exists because a short "?" or a raw pointer is not a literal question - it is a request to unpack the thing properly. ## When to use - The user writes `???` on its own - they did not understand the last thing and want it explained properly (full level). - The user writes `??` on its own - the same at medium depth; `?` on its own gives the short level. - The user writes `???`, `??` or `?` at the end of a message, right after a reference, a statement, or a term (for example `the audit gate ??`) - explain that specific thing, not the surrounding sentence. - The user writes a normal question ending with `?` (for example `Is it done?`) - answer that question at the depth and format its mark sets (short for `?`). - The `/credo:explain [subject] [level]` command is run - explain the given subject, or, if none is given, the thing the user was just pointing at. The level is full (default), medium or short. ## Recognising the shorthand …

How to install
mdr add marcel-bich/marcel-bich-claude-marketplace/explain@sha256:8d46f01ed2449906The line at the top of this page pins the label git:20261101.25e2dfa, 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.
