SQL Analyst

What it is

Given a schema and a question, it writes a single query with explicit column selection and a row limit, then explains the result. The rule that makes it safe is boring and effective: one query, no DDL, no writes, and the explanation must name the table and filter that produced the number.

Install

Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.

How to judge it

Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
