Add one new collection under kb/ with its binding COLLECTION.md, landing README, tag participation and routing, then validate it. Use when a project needs a new kind of long-lived content that no existing collection's contract fits.
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
# Add a collection Goal: a new directory `kb/<name>/` whose `COLLECTION.md` binds every artifact written there, which agents can find through the project's routing, and which passes validation. ## Inputs - **Name**: lowercase letters, digits and hyphens, used as `kb/<name>/`. - **Purpose**: what contribution the collection holds and for which reader. - **Model contract** (optional): an existing `COLLECTION.md` to model it on, in this project or supplied as a file. Ask for the name or purpose if either is missing. Do not invent a purpose from the name. ## 1. Check that a collection is the right answer Stop and report instead of creating anything when: - the content is in-flight work whose value is consumed when it finishes: it belongs in a workshop, `kb/work/<name>/`; - an existing collection's contract already covers the contribution: write there, or propose a subdirectory of it; - `kb/<name>/` already exists; - the name is `tags`, `sources`, `reports`, `work` or `types`. Commonplace commands rely on those locations for system roles, so the name is not available for ordinary content. ## 2. Write `kb/<name>/COLLECTION.md` …

How to install
mdr add zby/commonplace/cp-skill-add-collection@sha256:0b0503b70d250b77The line at the top of this page pins the label git:20261023.6e80d13, 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.
