This skill analyzes and optimizes SQL queries for improved performance. It identifies potential bottlenecks, suggests optimal indexes, and proposes query rewrites. Use this when the user mentions "optimize SQL query", "improve SQL performance", "SQL query optimization", "slow SQL query", or asks for help with "SQL indexing". The skill helps enhance database efficiency by analyzing query structure, recommending indexes, and reviewing execution plans.

This skill empowers Claude to analyze SQL queries, identify performance bottlenecks, and suggest optimizations such as index creation or query rewriting. It leverages the sql-query-optimizer plugin to provide actionable recommendations for improving database performance.
This skill activates when you need to:
User request: "Optimize this SQL query: SELECT * FROM orders WHERE customer_id = 123 AND order_date < '2023-01-01';"
The skill will:
User request: "I need help optimizing a query that filters on product_category and price. Can you suggest any indexes?"
The skill will:
EXPLAIN can help the optimizer identify bottlenecks more effectively.This skill can be used in conjunction with other database management plugins to automate index creation and query rewriting based on the optimizer's suggestions.
testing
This skill enables Claude to manage isolated test environments using Docker Compose, Testcontainers, and environment variables. It is used to create consistent, reproducible testing environments for software projects. Claude should use this skill when the user needs to set up a test environment with specific configurations, manage Docker Compose files for test infrastructure, set up programmatic container management with Testcontainers, manage environment variables for tests, or ensure cleanup after tests. Trigger terms include "test environment", "docker compose", "testcontainers", "environment variables", "isolated environment", "env-setup", and "test setup".
tools
This skill uses the test-doubles-generator plugin to automatically create mocks, stubs, spies, and fakes for unit testing. It analyzes dependencies in the code and generates appropriate test doubles based on the chosen testing framework, such as Jest, Sinon, or others. Use this skill when you need to generate test doubles, mocks, stubs, spies, or fakes to isolate units of code during testing. Trigger this skill by requesting test double generation or using the `/gen-doubles` or `/gd` command.
tools
This skill enables Claude to generate realistic test data for software development. It uses the test-data-generator plugin to create users, products, orders, and custom schemas for comprehensive testing. Use this skill when you need to populate databases, simulate user behavior, or create fixtures for automated tests. Trigger phrases include "generate test data", "create fake users", "populate database", "generate product data", "create test orders", or "generate data based on schema". This skill is especially useful for populating testing environments or creating sample data for demonstrations.
development
This skill analyzes code coverage metrics to identify untested code and generate comprehensive coverage reports. It is triggered when the user requests analysis of code coverage, identification of coverage gaps, or generation of coverage reports. The skill is best used to improve code quality by ensuring adequate test coverage and identifying areas for improvement. Use trigger terms like "analyze coverage", "code coverage report", "untested code", or the shortcut "cov".
