Update to Sigma

  "name": "sigma-workbook-quickstart",
  "description": "Builds a finished, professional Sigma workbook — dashboard or data app — from a fixed design system plus a corpus of pre-styled Code Mode blocks assembled via the sigma connector's build_workbook tool. Use for any request to build, create, make, generate, design, spin up, put together, or stand up a dashboard, data app, report, scorecard, KPI view, or analytics view, and for \"show me...\", \"visualize this\", \"chart this out\", or \"turn this into a dashboard\" over data that lives in Sigma. Claim these requests even when Sigma is never named and no source has been picked yet: a workbook is the default deliverable for a dashboard or data app. Not for answering one ad-hoc question or drawing a single throwaway chart — answer those inline with built-in visualization tools instead.",
