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, configure SIGMA_BASE_URL / SIGMA_CLIENT_ID / SIGMA_CLIENT_SECRET, troubleshoot 401/403 responses, or pick the right Sigma API hostname for their cloud. Use as a prerequisite when another Sigma skill needs an SIGMA_API_TOKEN.

Create, 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 author a new data model from a description, export/inspect/download an existing model's spec, edit columns or metrics, change a model's source, add relationships or row-level filters, or otherwise round-trip a data model through code. Requires an SIGMA_API_TOKEN — obtain via the sigma-api skill first.
