To learn more about different context types, check out our dedicated context section.
Now that you have something rudimentary working, you’ll want to augment your agent with richer context. We suggest doing this in one of two ways:
  1. Adding queries.
  2. Adding semantic models.

​
Adding queries as context

The cleanest way to add queries as context is to create a dedicated directory for your queries, then use a wild-card (*.sql) to slurp them all up into a context object, as follows: 
context:
  - name: queries
    type: file
    src:
      - "*.sql"
We suggest adding a comment at the top of each query explaining what the query is for, so the LLM has this context. The resulting queries can then be injected into your system_instructions using Jinja, as follows: 
system_instructions: |
  You are a data analyst. Write and execute SQL to answer the given question.

  {{ context.schema_information }}

  # Queries
  {{ context.queries }}

​
Adding semantic models as context

Sometimes you don’t need a full set of queries, but simply some snippets of SQL that represent metric calculations, dimension calculations, etc. — something minimal to bridge business logic to query logic. In these situations, building a semantic model is a good choice. Each semantic model has three required fields: measures, dimensions, and entities. measures are special, in that they require a sql field to run. The other objects only require a name field, though a few other fields (of note: sample (an array of sample data), description (a plaintext description of the column), synonyms (an array of synonyms for the column)). We suggest using the column name as name. A sample semantic model is shown below: 
entities:
  - name: content_id
    description: content_id
    sample: [1, 2, 3, 4]

dimensions:
  - name: month
    sample:
      - "2024-08"
  - name: property_grouping
    synonyms:
      - "property_grouping"
    sample:
      - "Fruit"
      - "Vegetable"

measures:
  - name: count_content_id
    sql: sum(distinct content_id)
You can learn more about semantic models in our dedicated semantic models section. At this point, your agent should be generally good to go, and you have the basic tools required to improve the agent when you encounter issues. To start familiarizing yourself with how to iterate on your agent more robustly, check out the next step of our guide, how to test your agent.
