DAG Authoring Skill

This skill guides you through creating and validating Airflow DAGs using best practices and MCP tools.

For testing and debugging DAGs, see the testing-dags skill which covers the full test → debug → fix → retest workflow.

⚠️ CRITICAL WARNING: Use MCP Tools, NOT CLI Commands ⚠️

STOP! Before running ANY Airflow-related command, read this.

You MUST use MCP tools for ALL Airflow interactions. CLI commands like astro dev run, airflow dags, or shell commands to read logs are FORBIDDEN.

Why? MCP tools provide structured, reliable output. CLI commands are fragile, produce unstructured text, and often fail silently.
