Turn LiveKit call recordings into HubSpot notes and Slack recaps

Build an agent workflow that runs on a cron every 30 minutes and turns finished LiveKit call recordings into structured sales-call notes in HubSpot, so nobody has to relisten to their own calls.

On each run: call LiveKit List Egress to find egresses that reached status EGRESS_COMPLETE since the last sweep. For each completed egress, pull the recording file URL from the egress location output, the room name, and any stored room metadata (assume the metadata carries a HubSpot contact id and/or the caller's phone number, set at Create Room time).

For each new recording, download the audio and send it to Deepgram Transcribe Pre-recorded Audio with diarization turned on and smart formatting enabled. Then read the transcript and produce: (a) a two to three sentence summary of the call, (b) a bulleted list of action items with owners, (c) a sentiment and next-step signal (e.g. positive / neutral / at-risk plus what should happen next), and (d) any commitments made on the call (dates, amounts, follow-up promises).

Match the transcript to the right HubSpot contact. First try the HubSpot contact id from the LiveKit room metadata. If that is missing, fall back to hubspot.get_contact with idProperty=phone using the caller's phone number from the metadata. If neither resolves a contact, post a Slack alert asking a human to attribute the call by hand, and skip HubSpot writes for this one.

When a contact is matched: use HubSpot Create Note associated with that contact carrying the full summary, action items, sentiment, and commitments. Then use HubSpot Create Task for each action item, with the promised due date if the transcript mentioned one and the owner if named. Then use Slack Send a Message to the sales team channel with a short recap (summary + top action items + link into the HubSpot contact record).

Guardrails to bake in:

1) Dedupe on egress_id via a running record (e.g. a store of already-processed egress ids or a last-processed-at cursor) so we never post the same call to HubSpot or Slack twice, even if the same egress shows up on a later sweep.

2) Skip any egress whose recording is shorter than 30 seconds (voicemail beeps, misdials, quick hang-ups) so we do not clutter HubSpot with noise. Make this threshold easy to change.

3) If no HubSpot contact can be resolved (no metadata contact id AND no phone match), post a Slack alert to the sales channel with the room name, call time, and recording URL, asking a human to attribute the call. Do not write anything to HubSpot in that case.

The workflow assumes LiveKit egress was configured with cloud storage the workflow can pull the recording from (S3 signed URL or a publicly accessible URL). Make the Slack channel, sweep cadence, and minimum-duration threshold configurable at setup time.
