Is the Sql2er skill free?

Yes. The skill itself is free from ystemsrx/sql_to_ER. SkillProof publishes the install command and an independent test verdict at no cost.

Does Sql2er work with Claude Code?

It is in our test queue — we run every skill on real work before issuing a verdict, and this one is scheduled.

How do I install Sql2er?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Sql2er with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
