jaz-pseudo-sql-8a1f3b — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited jaz-pseudo-sql-8a1f3b (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

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:
download_export(exportType=...) canonical report.search_* tools can't express cleanly.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.Call `get_pseudo_sql_schema` first for the live curated catalog (~70 tables, 91 join edges, 47 functions). Pass table to scope it to one table and its joins; the whole catalog is ~18k tokens, one table is ~1k.
The syntax guide is a SEPARATE call, get_pseudo_sql_syntax, returning the canonical jaz-pseudo-sql.md body in agentSkillsDoc.content. It is static (identical for every organization), so fetch it once, cache on version, and skip it entirely if you already have this skill loaded. The two were one response until 2026-09-03; combined they cost ~35k tokens on a call documented as "before any query", of which 42% was the unchanging guide.
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 a pseudo-SQL query from memory. The catalog grows; column names change; the live schema is the only source you should trust.
| Use this instead | When |
|---|---|
download_export(exportType='analysis-anomalous-invoices') etc. | Canonical anomaly / audit / risk reports; they're tuned, parameterized, and faster than re-deriving them in SQL. See jaz-api Rule 141. |
download_export(exportType='trial-balance') etc. | Statements (TB, BS, P&L, GL, cashflow). The reporting engine handles period closing rules, intercompany eliminations, FX revaluation. SQL would miss these. |
search_invoices(filter:...), search_bills, etc. | Listing entities with structured filters. Returns typed objects, supports pagination, faster than SQL. |
get_invoice(resourceId) etc. | Single-entity lookup by ID. |
view_auto_reconciliation | Bank reconciliation match suggestions. |
table scopes it to one table plus the joins touching it. Use the response's version (16-char hex) as a session-stable cache key. Org-agnostic.jaz-pseudo-sql.md body in agentSkillsDoc.content. Static across organizations; fetch once, cache on version, or skip it if this skill is already in context.downloadToFile=true to write to ~/Downloads/.PSEUDOSQL_VALIDATION_ERROR "only SELECT queries are supported".SELECT 1; SELECT 2; → 422 PSEUDOSQL_PARSE_ERROR "only a single SELECT statement is allowed per query". A trailing semicolon on one statement is fine.SELECT 1 (no FROM) → 422 PSEUDOSQL_VALIDATION_ERROR.validation_error "query must be a maximum of 16,384 characters in length". Note: this is the request-shape validator (different error_type from the SQL-engine validators).PSEUDOSQL_VALIDATION_ERROR "unknown table <name>" (lowercased in the error message). Call get_pseudo_sql_schema for the live inventory.truncated:true means "MORE rows matched than were returned in this preview", NOT "you hit the cap". To interpret: compare rowCount against your LIMIT clause or the preview cap (100). If you need every row, switch to export_pseudo_sql.X-Amz-Expires=900). Fetch immediately. If a fetch returns 403, call get_pseudo_sql_export(jobId) again for a fresh URL.run_pseudo_sql_and_download auto-keys from sha256(query).slice(0,16) so dedup is query-tied automatically. If you call export_pseudo_sql directly with a manual key, don't reuse it across different intents.get_pseudo_sql_schema (live; ~73 KB for the whole catalog, ~5 KB with a table filter).
