8 skills · Works with Claude Code, Codex, Cursor & more
Author dbt models, tests, and docs for analytics warehouses. Generates staging/mart layers, incremental models, snapshot logic, ref/source patterns, and CI tests for Snowflake, BigQuery, and Databricks.
claude install-skill community/dbt-models Author Dagster assets, jobs, sensors, and schedules. Generates asset-based DAGs, partitioned backfills, dbt+Dagster integrations, IO managers for warehouses, and observability with declarative scheduling.
claude install-skill community/dagster-orchestration Run fast analytical queries on Parquet, CSV, and JSON with DuckDB. Generates in-process pipelines, S3/HTTPFS reads, MotherDuck deploys, and pandas/polars integration for local-first analytics.
claude install-skill community/duckdb-analytics Migrate from pandas to Polars for fast, lazy DataFrames. Rewrites groupby/window/join chains using expression API, streams large datasets that don't fit in RAM, and emits idiomatic LazyFrame pipelines.
claude install-skill community/polars-dataframe Build data pipelines and ETL workflows. Generates extraction scripts, transformation logic, loading procedures, and scheduling for moving data between APIs, databases, warehouses, and file systems.
