Description

Find slow queries faster and fix them with your AI — with a real SQL audit guide included.

Curated collection plus an original guide. The 7 skills are MIT (free on GitHub); the SQL Query Audit Guide is original content by the pack publisher and is marked as such inside the zip.

Price: $19 once. No subscription and no upsell. Instant download after payment, with your link on the order page and in your receipt email. Re-download anytime from My Account > Downloads. 30-day refund. If it does not help you find slow queries faster, email [email protected] within 30 days and you get your money back.

What you get

  • 7 skills from addyosmani/agent-skills (MIT): performance-optimization, observability-and-instrumentation, security-and-hardening, source-driven-development, code-review-and-quality, debugging-and-error-recovery, test-driven-development.
  • Bonus: SQL Query Audit Guide (original, 2,700+ words) — EXPLAIN walkthrough, slow query log, indexing strategy, pagination (offset vs keyset), and 5 query rewrites. Clearly marked as original content, not part of the upstream project.
  • Self-contained — references bundled and paths fixed.
  • Playbook with 4 workflows: Slow Query Triage, N+1 Eradication, Production Outage Forensics, Data Layer Security Review.
  • License & attribution included.

Why this pack is different

The upstream project has no dedicated SQL skill. This pack is reframed as Backend & Database Performance and the gap is filled by the original Audit Guide — stated honestly on the page and in the zip.

Who it is for

Backend developers, data engineers and solo builders who debug slow endpoints and want a repeatable audit flow they can run with an agent.

System requirements

  • Claude Code, Codex, or Cursor. No extra dependencies.

Updates

v1.0.0 (upstream @ df1edb2). Free updates for 12 months. See CHANGELOG.md.

From the curator

Built because backend performance questions come up in almost every review — and the upstream lacked a focused SQL guide. Not an official distribution.

FAQ

Is the SQL guide from the upstream project?
No — it is original content by Yixing Store, marked as such.
