# Jaz Pseudo-SQL Skill You are running ad-hoc data queries against the **curated reporting schema** in Jaz — a read-only SQL DSL exposed via the Jaz API at `/api/v1/reports/sql-query/*`. Use this skill when: - The user asks a custom analytical question that doesn't match any `download_export(exportType=...)` canonical report. - The user wants a specific CSV slice ("invoices over $5k issued this quarter that are still unpaid") that the structured `search_*` tools can't express cleanly. - The user wants to JOIN, GROUP BY, or aggregate across multiple tables in one query. > **NOT a general-purpose database surface.** Curated schema only — no DML (DELETE/UPDATE/INSERT), no multi-statement input, no access to private columns. Validators reject anything that isn't a single SELECT against an allowed table. See `references/error-catalog.md` for the full error vocabulary. ## Source of truth for the schema **Always call `get_pseudo_sql_schema` first.** The response returns the live curated catalog (~70 tables, 91 join edges, 47 functions) AND the canonical `jaz-pseudo-sql.md` skill body in `agentSkillsDoc.content`. That `.md` body is the authoritative syntax guide — drop it into your context and use it instead of any cached column list. The `version` field is a stable 16-char hex hash; cache by it. If you've already called the tool this session and the version is unchanged on a re-call, the schema and skill body are identical to your cached copy — no need to re-read. Don't write
