Skill: Add a New Dagster Asset

Steps

1. Choose the layer file: asset_bronze.py, asset_silver.py, or asset_gold.py.

2. Declare the asset:

   @asset(group_name="<layer>", deps=["<upstream_asset>"])
   def <asset_name>(context: AssetExecutionContext) -> None:
       """One-line description."""
       settings = PipelineSettings()
       # ... logic
       context.add_output_metadata({"key": "value"})
   

3. File naming: follow <type>_<function>.py for any new utility files.

4. Resources (e.g. DbtCliResource): declare in function signature, already registered in definitions.py.

5. Register: load_assets_from_modules in definitions.py picks up the asset automatically if it's in the right module.

6. Validate:

   uv run dotenv -f .env run -- uv run dagster asset list
   uv run dotenv -f .env run -- uv run dagster asset materialize --select <asset_name>
