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.

Skills (5)
custom-sql-to-data-model
Scan Sigma workbooks for custom SQL elements, dedupe across workbooks, build or reuse Sigma data models, then repoint the workbooks via the v3alpha `:swapSources` endpoint. Use when you want to find ad-hoc SQL in workbooks and promote it to one reusable data model per unique query.
sigma-api
Authenticate against the Sigma Computing REST API and obtain a bearer token. Use whenever the user wants to call the Sigma API directly with curl/HTTP, exchange OAuth client credentials for an access token, sign in interactively via a browser OAuth login (authorization-code + PKCE), configure SIGMA_
sigma-data-models
Author, retrieve, or modify a Sigma data model spec (the JSON/YAML semantic-layer definition with sources, columns, metrics, relationships, filters, controls, folder groupings, and column-level security) by calling the Sigma REST API directly. Use when the user wants to build a new data model from e
sigma-plugin-authoring
Build, register, host, embed, and data-bind a bespoke Sigma custom plugin (@sigmacomputing/plugin) to recreate a source visualization for which Sigma has no native chart/KPI/table equivalent — a radial gauge, a custom heatmap, a sankey, or any bespoke viz kind outside Sigma's native element set. **U
sigma-workbooks
Build, edit, and iterate on Sigma workbook specs — the JSON definition you POST to /v2/workbooks (as `contents`), covering pages, layout, controls, charts, KPIs, tables, formulas, and sources. The Sigma OpenAPI is the source of truth for every shape and field; this skill adds navigation, style guida
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).
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).
Statically analyze a local JS/Electron app you're authorized to study, with file+line evidence, and build an original reimplementation of what you find. Experimental. Phase 1: JS/Electron static analysis. Phase 2: native ELF/PE/Mach-O container inspection. Phase 3: .NET assembly metadata. Phase 4: EVM bytecode inventory. Phase 5: CUDA fatbin, cubin and PTX inventory. Parses, never executes. Dynamic analysis is a future phase, not yet implemented.
Data engineering for Apache Airflow and Astronomer. Author DAGs with best practices, debug pipeline failures, trace data lineage, profile tables, migrate Airflow 2 to 3, and manage local and cloud deployments.
Binary reverse engineering, malware analysis, firmware security, and software protection research for authorized security research, CTF competitions, and defensive security
