Review docs/prose for Writing Guidelines compliance. Use when asked to "review my docs", "check writing style", "audit prose", "review docs voice and tone", or "check this page against the writing handbook".
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
# Writing Guidelines Review files for compliance with Writing Guidelines. ## How It Works 1. Fetch the latest guidelines from the source URL below 2. Read the specified files (or prompt user for files/pattern) 3. Check against all rules in the fetched guidelines 4. Output findings in the terse `file:line` format ## Guidelines Source Fetch fresh guidelines before each review: ``` https://raw.githubusercontent.com/vercel-labs/writing-guidelines/main/command.md ``` Use WebFetch to retrieve the latest rules.

How to install
mdr add vercel-labs/agent-skills/writing-guidelines@sha256:89a5f581193289b8The line at the top of this page pins the label v1.0.0, 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.
