SignalWire is a client of mine. They shipped POM in April.

We noticed that Microsoft released the POML (Prompt Orchestration Markup Language) yesterday.

SignalWire's version complies to markdown or XML.

The very close parallels may be pure coincidence, but it may not be.

If a clone job...not a good look to rip off OSS software without even a link to the inspiration.

If a coincidence: the co-founders at SignalWire have a lot of foresight (they hacked a tool use framework within two weeks of GPT-4, before OpenAI introduced tool calling).

Their AI toolset is worth a deeper look.
