Coral CLI Skill

Use this skill to answer data questions by querying connected sources with coral sql.

Discovery-First Workflow

Before writing any query, follow these steps:

1. List available regular tables:

SELECT schema_name, table_name, description, required_filters, guide FROM coral.tables;

2. Read the guide column — it contains per-table query patterns and gotchas. Use it.

3. List available table functions. Table functions expose API endpoints that require arguments. They are listed in coral.table_functions, not coral.tables, and their result columns are listed in result_columns_json, not coral.columns.
