Summary

Adds documentation for the new conversational SMS channel (sms.polyai) and the per-project SMS prompt decorator.

The upstream release introduces a two-way SMS channel that runs the same flows, topics, and tools as voice and webchat. A built-in SMS prompt decorator keeps responses short, plain-text, and within SMS segment limits, and can be overridden per project via the sms_decorator prompt field. Filler utterances and partial function outputs are disabled on the channel, older Raven variants are auto-swapped for a safe text-channel model, and auto-reasoning is enabled.

Changes

  • sms/introduction.mdx – split the page into Conversational SMS and Outbound SMS templates; document when to use sms.polyai, the channel identifier, the SMS prompt decorator (including override example), and the automatic model/behavior switches.
  • tools/classes/conv-object.mdx – add "sms.polyai" to the list of possible conv.channel_type values and clarify "sms.twilio" as the outbound variant.
  • glossary/introduction.mdx – update the Channel glossary entry to include conversational SMS.
  • webchat/multichannel.mdx – note that the per-channel prompt decorator also covers conversational SMS.
