DuckDB Local Skill for Claude
Local-first SQL analytics on files. Read, profile, clean, and export data without a warehouse.
When to Use This Skill
Activate when: Reading local files (CSV, Parquet, JSON, Excel) into DuckDB, profiling data quality, running SQL analytics on local data, cleaning/transforming datasets, exporting results to various formats.
Don't use for: Building dbt models (use dbt-transforms with DuckDB adapter), cloud warehouse administration, pipeline scheduling (use data-pipelines), Python DataFrame transformations (use python-data-engineering).
Scope Constraints
- Local files only -- does not manage cloud warehouse connections or remote databases.
- No cloud warehouse administration (Snowflake, BigQuery, Redshift).
- Reference files loaded on demand -- do not pre-load multiple references.
- File paths must be validated before use; never execute user-provided paths without checking existence.
