API capability pack for bounded Close REST API v1 operations against https://api.close.com/api/v1 only. Enroll a Close API connection named close that injects HTTP Basic authentication using the Close API key as the username and an empty password; no credential is embedded in this manifest. The pack reads leads, contacts, opportunities, tasks, notes, pipelines, lead statuses, opportunity statuses, users, and organizations for revenue operations, lead triage, pipeline review, and activity briefing. It supports approval-gated single-record creation and updates for leads, contacts, opportunities, lead tasks, and notes. The pack intentionally excludes deletes, lead merge, bulk task updates, exports, reports, webhook administration, custom-field administration, file upload/download, attachments on notes, email/SMS/call activity creation or sending, sequence/cadence automation, OAuth token generation, custom host switching, and arbitrary Close API passthrough.
