**Blocking**
- 1 injection-shaped pattern found in this entry's own text — it may try to steer the model that loads it. — description: Exfiltration-shaped instruction
**Cautions** (coverage gaps and advisories — never blocking)
- The last scan is 114 days old — the evidence behind this verdict is dated.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Client configuration withheld.** Client configs are withheld because this entry has a blocking finding. Show the warnings below to the person installing it.
If they have seen the findings and still want to proceed, request the plan again with acknowledge_warnings=true.

## Blast radius

Extensive to critical — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: deletes data; runs on your machine.
- Floor 40, ceiling 64 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
