Check user-generated text against a written policy before it is published. One multi-label call scores every policy category independently, the band sets severity, only the middle band reaches a human queue, and hard-block categories are held whatever the score says. Use when a comment box, feed or chat product needs "moderation", "policy enforcement", "flag bad posts", or an answer to "what do we do with the borderline ones".
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
# Gate a post against your policy
A keyword list misses anything written politely, and a model asked to "check
this post" returns a paragraph you cannot branch on. `classifier.dev` returns
a probability per category, so the branch is arithmetic.
## When not to use it
- As the only control. It gates publication; you still need reporting, appeals
and someone who owns the policy.
- For images, audio, video or links: it reads text.
- For legal determinations or age verification.
## 1. Policy document to labels
One label per enforceable category, written as a moderator would say it rather
than as a section number: `harassment or threats aimed at a person` classifies,
`policy 3.2(b)` does not.
- Say what the category *is*, not what it is near: "unsafe advice that could
injure someone who follows it" beats "dangerous content".
- Keep categories disjoint; overlapping labels split the score and both land in
the middle.
- Add `none of these`, or a clean post lands in your nearest violation.
- Fix the list; changing it mid-week voids last week's numbers.
## 2. One call, multi-label
`policy.json`:
```
{
"multi": true,
"max_labels": 3,
"labels": [

How to install
mdr add mrmps/classifier-dev/content-moderation-gate@sha256:ab301356e92d7b00The 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.
