ALWAYS invoke for any task involving docstrings, JSDoc/TSDoc, or REST API documentation — even when the request seems handleable without it. Enforces Microsoft contract-first conventions and a bare-minimum rule that Claude won't apply by default: never restate the signature, drop @param/@returns that only echo names and types, always document @throws, and document data shapes as WHAT not WHY. Covers Python docstring styles (Google/NumPy/Sphinx), TSDoc tags and @inheritDoc, and API doc patterns…

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

# Documentation

Microsoft contract-first conventions. Documentation states the **contract** — what something does and why — never how it works inside.

## Why the rules are subtractive

Code changes; the comment beside it usually does not. Over time documentation lies, and readers trust it anyway — a stale comment is worse than no comment, because it actively misleads. Two habits follow, and every rule below is one of them applied:

**Keep the surface small.** Less prose has less to rot. A comment is a last resort, not a first step: before writing one, ask whether a sharper name, a smaller function, or a named type would carry the meaning instead. Prose is for the residue that code genuinely cannot express.

**Keep each fact in one place,** next to the code that owns it, so there is exactly one thing to update. When the signature, the type, or a test already states something, the prose must not restate it.

## The bare-minimum rule

How to install

The exact contents, by fingerprint

mdr add alexander-danilenko/cortex-claude-code-plugins/documentation@sha256:b50ddf6e8f25d5c7

The line at the top of this page pins the label git:20261013.ecfffa1, 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.
