Fresh session per sweep — state lives on the HubSpot lead record itself (a kortix_followup_drafted property + timestamp marks a lead handled), not in a local ledger file. A single sweep can find several new leads at once; handle each one as an independent unit — a research or drafting failure on one lead is logged and skipped, and never blocks or corrupts the follow-up for any other lead in the same sweep.

Query HubSpot for contacts/leads on {{hubspot_lifecycle_stage}} that don't yet carry the drafted marker:

GET /crm/v3/objects/contacts/search
  filterGroups: [
    { propertyName: "lifecyclestage", operator: "EQ", value: "{{hubspot_lifecycle_stage}}" },
    { propertyName: "kortix_followup_drafted", operator: "NOT_HAS_PROPERTY" }
  ]

Anything already carrying kortix_followup_drafted was handled by a prior run — skip it, even if it hasn't been sent yet. Sending is a human decision, not a signal to re-draft.

Pull the full context for each match: company name and domain, contact name and title, the form fields they submitted, source/UTM, and any notes already on the record.

Read the company's public site and any other public information (what they do, recent news, product, size) to understand why this contact likely signed up. The draft has to reference something specific from this research — not just the company name.

Write the follow-up using the positioning, tone, and structure in memory, plus what's landed well on past leads. Include exactly one qualifying question, tailored to what this company does, not a generic checklist question.

Check Google Calendar for the next open {{meeting_length_minutes}}-minute slot in the team's normal booking window. Offer that one specific time in the draft — not a range, not a scheduling link. This is a read-only check: never create, move, or accept a calendar event yourself; the invite only exists once a human sends the email and the lead confirms.

Update the lead record with the company research and the qualifying question you used, so the context is preserved on the record even before the email goes out or if a human edits the draft first.

Place the drafted follow-up in {{approval_channel}} as a draft only. Do not send it. Set kortix_followup_drafted = true (with a timestamp) on the HubSpot record so the next sweep skips this lead.
