Edit Parameters

Edit Parameters

Skill for defining and modifying dynamic parameters in the Lightdash semantic layer.

Purpose

Enables the creation of dynamic, reusable variables that users can modify at runtime in dbt YAML or lightdash.config.yml.

Behavior

1. Parameter Scope: Define parameters either at the project level (lightdash.config.yml) or the model level (dbt YAML).
2. Type Safety: Ensure parameters use supported types (string, number, date).
3. Template Usage: Reference parameters in SQL using ${lightdash.parameters.name} or ${ld.parameters.name}.
4. Reference Consultation: ALWAYS check references/basics.md and references/advanced.md for syntax patterns.

References

• Basics: Parameter definition and simple types.
• Advanced: Multi-select, custom options, and joined model parameters.
• Global Config: Project-level parameters.
• SQL Templating: Using ${lightdash.parameters.name}.

Rules

• ALWAYS provide a default value for parameters.
• Add clear description tags to help end-users understand the parameter's effect.
• Prefer model-level parameters for better encapsulation.
• Refer to read-parameters to verify existing variables before adding new ones.
