Queries the data warehouse with SQL and answers business questions about data. Use when answering anything that needs warehouse data - counts, metrics, trends, aggregations, joins across tables, data lookups, or ad-hoc SQL analysis (for example "who uses X", "how many Y", "show me Z", "find customers", "what is the count").
Answer business questions by querying the data warehouse. The kernel auto-starts on first exec call.
All CLI commands below are relative to this skill's directory. Before running any scripts/cli.py command, cd to the directory containing this file.
Pattern lookup — Check for a cached query strategy:
If a pattern exists, follow its strategy. Record the outcome after executing:
Concept lookup — Find known table mappings:
Table discovery — If cache misses, search the codebase (Grep pattern="<concept>" glob="**/*.sql") or query INFORMATION_SCHEMA. See reference/discovery-warehouse.md.
Execute query:
Cache learnings — Always cache before presenting results:
Present findings to user.
| Function | Returns |
|---|---|
run_sql(query, limit=100) | Polars DataFrame |
run_sql_pandas(query, limit=100) | Pandas DataFrame |
run_sql_many(queries, limit=100) | List of Polars DataFrames (one per query) |
pl (Polars) and pd (Pandas) are pre-imported.
Run independent queries together with run_sql_many — they execute concurrently (Snowflake async / connection-pool fan-out) instead of one at a time:
run_sql_many is fail-fast: if any query errors, the call raises and the results of the queries that succeeded are discarded. Use separate run_sql calls if you need partial results.
Timeouts: exec waits up to 120s by default, then interrupts the query and returns a "client stopped waiting" message (the query may still finish server-side). Raise it for known long-running queries: uv run scripts/cli.py exec "..." -t 600.
Idle kernel: the kernel self-terminates after 2h idle (preserving state until then). Override with ASTRO_KERNEL_IDLE_TIMEOUT (seconds; 0 disables).
