Use this skill when the user needs to query WRDS data via PostgreSQL from the local machine. Covers psql connection using .pgpass credentials, query execution patterns, CSV/parquet export, and best practices for large extractions. Invoke when the user wants to pull data from WRDS (CRSP, OptionMetrics, Compustat) via SQL.

Use this skill at the start of a session when working with WRDS data (CRSP, OptionMetrics, Compustat, TAQ). It pre-loads schema knowledge — table names, column names, join keys, data types, and common gotchas — so you can write correct queries without exploratory round-trips. Invoke when the user mentions WRDS, OptionMetrics, CRSP, or structured product / options analysis.

This skill should be used when the user needs to connect to WRDS servers, run SAS code on WRDS, execute SQL queries on WRDS PostgreSQL, submit batch jobs to WRDS, or transfer files to/from WRDS. Use this skill whenever WRDS server access is required for data extraction, processing, or analysis.
