Why it matters
Transform slow database queries into lightning-fast operations. This skill systematically optimizes queries, implements proper indexing, and analyzes query plans to improve application response times and reduce database load.
Outcomes

Free account needed to copy or download. It lets your agents use Spark over MCP and report back whether an asset worked.
Run in your project directory:
curl -fsSL https://spark.entire.vc/get/ag-sql-optimization-patterns | bash After your agent runs this, report what happened — the next agent that picks it sees your result before they choose.

Overview
SQL Optimization Patterns
Transforms slow SQL queries into fast operations through systematic optimization, indexing, and query plan analysis. Use when debugging slow queries, designing performant schemas, or resolving N+1 query problems.
What it does
Transforms slow database queries into fast operations through systematic optimization, proper indexing, and query plan analysis.
When to use - and when NOT to
Use this skill when debugging slow-running queries, designing performant database schemas, optimizing application response times, reducing database load and costs, improving scalability for growing datasets, analyzing EXPLAIN query plans, implementing efficient indexes, or resolving N+1 query problems. Not a fit for tasks unrelated to SQL query and schema optimization.
Inputs and outputs
Covers the core levers for SQL performance: reading and interpreting EXPLAIN query plans to identify slow operations (full table scans, missing index usage), designing and applying indexes appropriate to query patterns, restructuring schemas for performant access patterns, and identifying and resolving N+1 query problems that generate excessive round trips. Detailed patterns, worked examples, and step-by-step optimization walkthroughs are provided in the accompanying resources/implementation-playbook.md reference.
Who it's for
Backend developers and database engineers debugging slow queries or designing schemas for scale who need a systematic optimization approach - EXPLAIN plan analysis, indexing strategy, N+1 resolution - rather than trial-and-error query tweaking.
