Sweep a marketplace or catalogue with a keyless classification API: one pass for category, one multi-label pass for prohibited, counterfeit and misstated-condition signals, one for review-abuse patterns, severity set by the calibrated confidence band, and a queue file only a person acts on. Use on "check these listings", "find counterfeits", "audit the catalogue", "are these reviews fake", or before a category goes live.
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
# Check listings and reviews for the usual abuse
`classifier.dev` tags text against labels you write and returns a score per
label. No key. Three passes over a catalogue export give a category, a set of
policy signals and a review-abuse read, each with a number. It removes nothing
and messages nobody. It fills a queue.
## When not to use this
- Enforcement. Nothing here suspends a seller, delists an item or answers a
trademark claim. Those need a person, usually with counsel.
- Anything turning on the image, the invoice, the seller's history or a brand's
authorised-seller list. This reads listing text only.
- Prohibited lists (knives, supplements, safety marks) differ by market. Write
the labels per market, with whoever owns policy.
## Pass 1 — category, with an escape hatch
```
"labels": ["consumer electronics and accessories", "kitchen and home",
"health and supplements", "knives and weapons", "none of these"]
```
Single label. Miscategorisation is an old listing trick, and a category that
disagrees with a signal is a strong review candidate. Keep `none of these`:
without it every listing lands in a category whatever it sells.

How to install
mdr add mrmps/classifier-dev/listing-hygiene-check@sha256:4a003f73bc6351d4The line at the top of this page pins the label git:20260919.33ae531, 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.
