Use this skill when answering ad-hoc data questions that aren't covered by download_export (canonical reports: anomaly, audit, aging, P&L, BS, GL, statement of account) or search_* tools (entity listings with structured filters). Pseudo-SQL is a read-only DSL against Jaz's curated reporting schema: single SELECT statement, ≤100 row sync preview or full async CSV export. Tools: get_pseudo_sql_schema (live catalog, optional `table` filter), get_pseudo_sql_syntax (the static syntax guide), downloadable jaz-pseudo-sql.md skill body), preview_pseudo_sql, export_pseudo_sql, get_pseudo_sql_export, run_pseudo_sql_and_download.
