Ruby Optimise

What it does

This skill, Ruby Optimise, refactors Ruby code to improve performance and efficiency. It leverages a community-maintained guide of 42 best practices across eight categories, prioritized by impact. The tool can automatically suggest and apply these optimizations to boost application speed and reduce resource consumption.

When to use it

• When writing new Ruby code or gems.
• For optimizing ActiveRecord queries and database access patterns.
• When processing large collections or building data pipelines.
• During code reviews to identify memory bloat and GC pressure.
• To configure Ruby runtime settings for production environments.

Key capabilities

• Applies rules from a community-maintained performance optimization guide.
• Prioritizes optimizations based on impact (CRITICAL, HIGH, MEDIUM-HIGH, MEDIUM, LOW-MEDIUM).
• Covers categories including Object Allocation, Collection & Enumeration, I/O & Database, String Handling, Method & Dispatch, Data Structures, Concurrency and Runtime & Configuration.
• Provides specific refactoring suggestions like avoiding unnecessary object duplication (alloc-avoid-unnecessary-dup) or using single-pass collection transforms (enum-single-pass).

Example prompts

• "Optimize this Ruby code for performance: [paste code snippet]"
• "Refactor this ActiveRecord query to improve database access patterns."
• "Review this data pipeline and suggest optimizations based on community best practices."

Tips & gotchas

• The skill relies on the provided community guidelines; results will be most effective when applied to Ruby code.
• Be aware that automated refactoring may introduce subtle changes, so thorough testing is recommended after applying optimizations.
