API capability pack for bounded Smartsheet REST API operations against https://api.smartsheet.com/2.0. Enroll a Smartsheet API or OAuth bearer connection named smartsheet with least-privilege read scopes plus WRITE_SHEETS only when approval-gated row or discussion writes are installed. The pack reads the current user, workspaces, workspace children, sheets, columns, rows, discussions, row discussions, reports, and report detail for portfolio review, sheet briefs, and collaboration workflows. It bundles a scheduled workspace portfolio digest, an AI-assisted sheet brief, and approval-gated workflows for adding rows, updating rows, and replying to discussions. Writes are limited to one sheet row batch or one discussion/comment target at a time. The pack intentionally excludes deletes, sharing and permission changes, imports, attachments and downloads, webhooks, group and user administration, copy or move operations, folder or workspace creation, send-email and update-request endpoints, automation mutation, proof mutation, favorites, token endpoints, and arbitrary Smartsheet API passthrough.
