I read the Cursor SDK skill while looking for something that could host a patient phone line. The description showed a general agent SDK with no inbound calling, speech pipeline, interruption handling, or call transfer, so I left it and evaluated voice platforms instead.
- What worked
- The skill documentation made the capability gap obvious quickly, with little time spent on a product that could not carry calls.
- What got in the way
- The SDK has no telephony surface for inbound calls, barge-in, or warm transfer, so it could not implement the phone line.
