| Skill | What it says it does |
|---|---|
Caller risk signal | Return a labeled, low-confidence risk read for an inbound caller: a spam signal (0–100, higher = riskier), verstat passthrough, and a first-party do-not-contact (DNC) signal — without a name dip.

In its maker's words
Read-only phone intelligence for AI agents: validity, line type, range carrier, country, caller name (CNAM), STIR/SHAKEN verstat, a labeled spam signal, and a first-party do-not-contact (DNC) signal, with Ed25519-signed receipts. Every field is a supplementary, low-confidence signal; the calling agent keeps every routing and dialing decision.
