Turn the user's labels on repo prose, or their notes from reviewing a document in Plannotator, into calibrated Vale rules.
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
# Prose Lab
The user flags writing anti-patterns in this repo's documents. The lab turns a pattern with enough examples into a Vale rule that holds a precision floor on text it was not written from, and retires shipped rules the corpus stops supporting. `.claude/rules/vale-styles.md` sets the bar every rule meets.
Run every command as `bun ${CLAUDE_SKILL_DIR}/../../../packages/prose-lab/lab.ts <command>`. `--help` on any command lists its flags. Data lives in `packages/prose-lab/data/`, gitignored. Run `sync pull` before a sitting and `sync push` after one.
## Arguments
- `--corpus <name>`: the documents `sweep` lints. Default: `skills`.
## Flag
Run `sweep`, then `serve` in the background, and hand the user the URL. The sample tab takes right, wrong, or unsure per hit with an optional pattern slug. The document tab flags spans that the rules missed. Stop until the user says the sitting is done.
## Review
…Read the whole file at its exact version.
How to install
mdr add bendrucker/claude/prose-lab@sha256:e9358692df8b6adcThe line at the top of this page pins the label git:20261030.cb11d4a, 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.
