deploying-airflow covers three distinct deployment paths: astro cli for managed operations, docker compose for local and dev environments, and kubernetes helm charts for production orchestration. includes ci/cd patterns and configuration examples.

debugging-dags provides structured root cause analysis for airflow dag failures using a four-step investigation workflow, failure categorization, and tool-specific commands for astro and oss deployments.

cosmos-dbt-core bridges dbt core projects and airflow through three assembly patterns and eight execution modes, requiring upfront verification of engine type, warehouse, and airflow version before implementation.

testing-dags automates iterative test-debug-fix cycles for airflow dags with diagnostic output and validation commands, supporting timeouts and retries across multiple failure scenarios.

tracing-downstream-lineage helps engineers identify what breaks when altering data tables or pipelines by mapping consumer dependencies, categorizing risk, and generating impact reports before deployment.

managing-astro-local-env covers starting, stopping, and restarting local airflow containers via astro cli, viewing logs across services, accessing container shells, and troubleshooting common docker and standalone setup failures.

creating-openlineage-extractors covers building custom lineage capture for unsupported airflow operators via two patterns: direct methods on owned operators or standalone extractors for third-party code, with registration via airflow.cfg or environment variables.
