Rerank retrieved passages by whether each one answers the question, drop the near-misses before they reach the prompt, and check every citation in the answer against the passage it points at. Use after a vector search returns twenty plausible chunks, or when an answer needs its citations verified. Triggers on "rerank these", "which chunks answer this", "check these citations", "my RAG cites the wrong chunk".
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
# Rerank and verify with a yes/no call
Vector search returns what is *near* the question. Much of it is about the right
subject and answers nothing, which costs context and invites citations pointing
at passages that never made the claim.
`classifier.dev` answers one question per passage — does this answer it — with a
calibrated confidence, keyless, in one batched call. It never writes text; the
answer stays yours to write.
## When not to use it
Not for first-stage retrieval (it does not embed or search), not for five
passages already in context, and not for ranking a set that is entirely
relevant — every passage gets a label, so a uniformly good set all comes back
`answers the question`.
## Step 1: one call over every candidate
```python
import json, urllib.request
def rerank(question, passages):
body = {"labels": ["answers the question",
"related but does not answer",
"unrelated"],
"inputs": passages, # up to 1,000 per request
"instructions": f"The question is: {question}"}
req = urllib.request.Request(

How to install
mdr add mrmps/classifier-dev/rag-reranker@sha256:31507c5c11ea0450The 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.
