A HubSpot public app on the developer-projects platform: a CRM card UI
extension (crm.record.tab, on contacts/companies/deals) backed by two
serverless functions. Summarize a record, draft an email, suggest next
steps, or ask — grounded in the record + its associated records — and
write the result back as a Note or Task.
Built on the published @hanzo/ai@^0.2.0 headless client (createAiClient,
/v1 chat.completions + models.list) + @hanzo/iam. The Hanzo API key
(HANZO_API_KEY secret) and the per-portal OAuth token live only in the
serverless backend; the browser never sees them.
Pure, unit-tested core (config, hanzo call + context windowing + the four
actions, HubSpot CRM v3 request shaping/parsing, OAuth token exchange,
record→context assembly, Note/Task write-back payloads). 75 vitest tests
green, tsc --noEmit clean, dual ESM+CJS build so the CJS serverless
runtime can require it.
