Expert SQL query generation for DBX Studio. An agent skill from Dbxstudio/dbx-studio.

  • Works in 4 steps: Execute tool to get data → Answer the user's question directly with… → Show SQL in sql blocks only if the user… → …
  • Debugging SQL queries against user database connections
  • SKILL.md covers Supported Dialects, Query Patterns, Tool Usage in DBX Studio AI and Query Safety Rules, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

SQL Queries Tool is an agent skill from Dbxstudio/dbx-studio. Expert SQL query generation for DBX Studio. Use when writing, optimizing, or debugging SQL queries against user database connections.

Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases, covering SQL. It works with SQL. The repository describes itself as: Free Open-source AI SQL client that helps developers and data teams explore databases using natural language. The licence is Apache-2.0.

When your agent uses it

  • Debugging SQL queries against user database connections
  • Tasks that involve SQL

Example prompts

  • “/sql-queries-tool”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Execute tool to get data
  2. Answer the user's question directly with the result
  3. Show SQL in sql blocks only if the user asks "how" or "show me the query"
  4. Present numbers clearly: "There are 1,247 orders this month"

What it can do on your machine

Read from SKILL.md and the folder at commit 9592eb7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are sql).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

SQL Queries Tool loads about 577 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 203 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~577

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SQL Query Expert — DBX Studio

This project supports multiple database backends via user connections. Always write dialect-appropriate SQL.

Supported Dialects

BigQueryVia MCP connector
DatabricksVia MCP connector
MySQLVia connection string
SQLiteVia connection string

Query Patterns

Safe SELECT with limit

Always add LIMIT unless the user explicitly wants all rows:

sql
SELECT * FROM "schema"."table" LIMIT 100;
CTEs for complex queries
sql
WITH ranked AS (
  SELECT *, ROW_NUMBER() OVER (PARTITION BY category ORDER BY created_at DESC) AS rn
  FROM orders
)
SELECT * FROM ranked WHERE rn = 1;
Aggregations
sql
SELECT
  DATE_TRUNC('month', created_at) AS month,
  COUNT(*) AS total,
  SUM(amount) AS revenue
FROM orders
GROUP BY 1
ORDER BY 1 DESC;
Window Functions
sql
SELECT
  user_id,
  amount,
  SUM(amount) OVER (PARTITION BY user_id ORDER BY created_at) AS running_total
FROM transactions;

Tool Usage in DBX Studio AI

The AI has access to these tools — always use them rather than guessing:

ToolWhen to Use
read_schemaFirst call — understand table structure
get_table_dataPreview rows before writing complex queries
execute_queryRun SELECT queries (SELECT/WITH only)
describe_tableGet column details, FK relationships
get_table_statsRow counts, distributions
generate_chartVisualize query results

Query Safety Rules

  • Only SELECT and WITH (CTEs) are permitted via execute_query
  • Always quote identifiers: "schema"."table"."column"
  • Add LIMIT automatically unless the user asks for all data
  • Validate table/column names exist via read_schema or describe_table first

Response Format

  1. Execute tool to get data
  2. Answer the user's question directly with the result
  3. Show SQL in ```sql blocks only if the user asks "how" or "show me the query"
  4. Present numbers clearly: "There are 1,247 orders this month"
