Skill: Add a New Silver dbt Model

Steps

1. Identify the raw source table — check dbt/models/sources.yml; add it if missing.

2. Create the SQL model at dbt/models/silver/<layer>_<source>__<entity>.sql:

   {{ config(materialized='table') }}
   
   SELECT
       {{ clean_text('col') }}   AS col,
       {{ parse_bdpm_date('date_col') }} AS date_col
   FROM {{ source('raw', 'table_name') }}
   WHERE {{ is_valid_cis('cis') }}
   

3. Create the contract at dbt/models/silver/<layer>_<source>__<entity>.yml:

   version: 2
   models:
     - name: <layer>_<source>__<entity>
       description: "..."
       columns:
         - name: <pk>
           data_tests: [unique, not_null]
   

4. Add a new macro in dbt/macros/ if any transformation is reused across models.

5. Validate locally:

   uv run dotenv -f dbt/.env run -- uv run dbt run --project-dir dbt --profiles-dir dbt --select <model_name>
   uv run dotenv -f dbt/.env run -- uv run dbt test --project-dir dbt --profiles-dir dbt --select <model_name>
