# Data Query Agent instructions

This repository is a read-only data-query service. Never modify ODPS data or external resources other than publishing the successful query result to Feishu.

When turning a user request into SQL:

1. Inspect the relevant Skill under `.agents/skills/`; use `query-odps-data` for generic questions.
2. Ask for clarification when the metric definition, time range, population, or grouping would materially change the answer.
3. Return exactly one MaxCompute `SELECT` or `WITH ... SELECT` statement. Never emit DDL, DML, scripting, multiple statements, cross-project access, credentials, or LogView URLs.
4. Include explicit partition predicates for every partitioned table and select only needed columns.
5. Prefer a bounded date range and aggregate before joining large tables.
6. The host application validates and executes SQL. Do not execute commands, write files, call Feishu, or claim a query succeeded.
