Is the OMA DB Agent skill free?

Yes. The skill itself is free from first-fluke/oh-my-agent. SkillProof publishes the install command and an independent test verdict at no cost.

What is the OMA DB Agent SkillProof Score?

8.8/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install OMA DB Agent?

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 OMA DB Agent 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.

Test report

Verdict: Tested · Works
Score: 8.8/10
Tested: Jul 13, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · dd9418d

The SKILL.md packs a genuinely thorough 194-line database spec (3NF/BASE tradeoffs, ACID vs consistency documentation, ISO 27001-aware guardrails, vector/RAG retrieval rules), but two of its own references (../_shared/core/*, ../oma-observability/SKILL.md) live outside the oma-db folder and go dark on a plain skill-dir copy.

What OMA DB Agent does

Guides SQL, NoSQL, and vector-database design end to end — ERD/schema modeling, normalization vs denormalization, transaction/isolation design, capacity and backup planning, and ISO 27001/22301-aware recommendations. Triggers on database, schema, ERD, migration, indexing, RAG retrieval, or vector-index requests.
