Is the Database Design skill free?

Yes. The skill itself is free from CloudAI-X/claude-workflow-v2. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Database Design SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Database Design?

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 Database Design 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.

Trigger phrasings — SHOULD load: (1) "Design a schema for a multi-tenant orders system"; (2) "This Prisma query is slow, I think I have an N+1 problem"; (3) "How do I plan a zero-downtime migration to rename a column?". Should NOT load: (4) "Build me a dashboard UI that displays user data" (frontend, adjacent via 'data'); (5) "Debug why my REST endpoint returns 500" (backend, no DB work). All 5 judged correctly = 5/5. Output measured: skill-guided result added a trigger-maintained comment_count counter, a partial index WHERE status='pending', CONCURRENTLY index creation, and cursor pagination that the baseline missed — clearly better with specifics (8/10). Docs claims (SQL+NoSQL schema/indexing/query-opt/migrations) match the body with no overselling.

What Database Design does

A pure-prompt reference skill that guides schema normalization, index selection, EXPLAIN reading, N+1 prevention, zero-downtime migrations, connection pooling, and ORM/NoSQL patterns. Triggers when the task involves designing tables, optimizing queries, planning migrations, or fixing database performance. Self-contained markdown with concrete SQL/Python/JS examples.

How to install Database Design

Clone the repo and copy the skill directory into your Claude config: `git clone https://github.com/CloudAI-X/claude-workflow-v2 && cp -r claude-workflow-v2/skills/database-design ~/.claude/skills/`. Or add the whole marketplace as the `project-starter` plugin via `/plugin marketplace add CloudAI-X/claude-workflow-v2`.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Database Design
