Claude skills for SQL: common questions
Is there a Claude skill for SQL?
There are 455 of them, spread over 192 repositories on GitHub. Named for it and most starred: postgresql table design (wshobson/agents, ★ 42k), sql optimization patterns (wshobson/agents, ★ 42k) and creating oracle to postgres master migration plan (github/awesome-copilot, ★ 41k). Stars rate the repository a skill sits in, not the skill.
How do I install a Claude skill for SQL?
For SQL, take the postgresql-table-design folder from wshobson/agents (the folder that holds SKILL.md) into ~/.claude/skills/ to use it in every Claude Code project, or into .claude/skills/ for one project. In the Claude apps, zip that folder and upload it as a custom skill in settings.
Are all these SQL skills in English?
No: Strix•SQL 注入 is written mainly in Chinese, Japanese, Korean or Russian rather than English, though the SQL task is the same. Claude can follow it either way, but read it before you install.
What should I check before installing a SQL skill?
A SQL skill is instructions Claude follows, and it can bundle scripts Claude runs, so read SKILL.md and every script first: for postgresql table design, that is everything in the postgresql-table-design folder. Red flags: piping a download into a shell, sending files to a URL, and instructions to hide what it does from you.
Are these SQL skills maintained?
337 of the 455 SQL skills sit in repositories that changed in the 30 days before 31 Oct 2026.
Are these SQL skills official?
No. None of the 455 SQL skills comes from Anthropic's own skills repository, so all of them are community-made across 192 repositories.
