## Before you call it

1. Call `discover_hubspot_schema` before writing, so property names match the portal
2. Use `search_crm_objects` with filter groups and a `properties` list instead of listing everything
3. Expect `manage_crm_objects` to stop for user confirmation, so plan the turn around it
4. Read `policyName` on a 429 to tell a 10-second burst from the daily cap
5. Ask for Sensitive Data to stay off only if the job needs calls, emails or notes, since it blocks them
