sigma-migration-skills

Canonical Sigma authoring skills every converter defers to: sigma-workbooks (workbook spec — element kinds, source kinds, controls, formulas, formatting, layout), sigma-data-models, and custom-sql-to-data-model. Install this ALONGSIDE any converter — they assume it is present for the current Sigma spec surface.

5 skills

Domo → Sigma — DataSets → Sigma data model (flat materialized tables → table elements), Beast Mode calc fields → Sigma formulas (MySQL-dialect SQL), and cards → charts/KPIs/pivots (every card's Summary Number → a KPI, never a table). Ports page + card filters as controls, detects PDP policies for opt-in row-level security, and verifies warehouse parity (live step). Bundles a read-only domo-assessment skill (public governance-dataset inventory → value/cost-ranked migration-readiness readout).

Power BI models/reports → Sigma, DAX translation + gap-scout, with parity verification. Bundles powerbi-to-sigma + powerbi-assessment + powerbi-import-to-snowflake (Import-mode data landing).

3 skills

Tableau workbooks/datasources → Sigma data model + workbook, with parity verification. Bundles tableau-to-sigma + tableau-assessment + tableau-vds-to-cdw (lands published-datasource/extract data in Snowflake or Databricks when it isn't already in the warehouse).

GoodData Cloud / GoodData.CN → Sigma — the declarative workspace layout (LDM + analytics model) → Sigma data model + workbook (datasets/attributes/facts/references → DM; MAQL metrics → Sigma formulas; insights → charts/KPIs/pivots; dashboards → pages + layout), with parity verification and opt-in user-data-filter RLS. Flags compute-only MAQL and exotic widgets rather than mis-converting. Bundles gooddata-to-sigma + gooddata-assessment.

2 skills

Hex → Sigma — SQL cells, single-value/METRIC cells, and EXPLORE charts → Sigma data model + workbook, built from a project's .hex.yaml export (Hex's REST API doesn't return cell content), with app layout carried over and warehouse parity verification. Bundles a read-only hex-assessment skill (scaffolded, not yet built out).

2 skills

Looker (LookML semantic model + LookML/user-defined dashboards) → Sigma data model + workbook (KPI/bar/line/area/pie/donut/scatter/table/pivot, table calcs), with 3-way warehouse parity. Bundles looker-to-sigma + looker-assessment.

2 skills

Metabase models, questions, and dashboards → Sigma data models + workbooks, with MBQL/pMBQL translation, native-SQL remodeling, controls, exact-grid layout, and parity verification. Bundles metabase-to-sigma + the read-only metabase-assessment.

2 skills

MicroStrategy (Strategy One) → Sigma — dossier + classic semantic model (attributes/facts/metrics over a star schema) → Sigma data model + workbook, with deterministic reproduction of Analytical-Engine row-collapse quirks and row-level parity verification. Bundles microstrategy-to-sigma + microstrategy-assessment.

2 skills

Mode Analytics Reports (SQL Queries + Charts) -> Sigma, with parity verification. No formula translation needed -- Mode's SQL already runs in the target warehouse dialect.
