## Prerequisites Before creating entities, ensure you are on the correct workspace and branch. Use `get_session_workspace_and_branch` to check the current session context. For development work, create a branch with `create_workspace_branch` (the session switches automatically). See the `workspace-branch` skill for the full workspace/branch tool reference. --- ## Overview A Honeydew **entity** is the foundational modeling object — a named, governed representation of a business concept at a specific granularity. Every metric and calculated attribute is anchored to an entity. An entity maps to a data warehouse (Snowflake, Databricks, or BigQuery) table, view, custom SQL query, or a virtual derivation from the semantic model. When creating an entity you are answering three questions: 1. **What is this?** — the business concept (orders, customers, products, locations) 2. **What makes a row unique?** — the granularity key (primary key column(s)) 3. **What columns should be exposed?** — the initial attribute mapping from source columns > This skill focuses on the entity shell: source, key, and attribute mapping. > Use `attribute-creation` to add calculated attributes and `relation-creation` to wire up joins afterwards. --- ## Creation Methods ### Quick Import: import_tables Use `import_tables` to quickly import one or more data warehouse tables into the semantic model. Each table becomes an entity with its columns automatically mapped as attributes. This is the fastest wa
