SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps developers identify and resolve performance bottlenecks in their Node.js, Python, or browser applications, leading to faster and more efficient software.

Core Features & Use Cases

Automated Profiling: Detects runtime environments and sets up appropriate profiling tools (e.g., clinic.js, cProfile, Lighthouse).
Bottleneck Identification: Scans code for common anti-patterns like synchronous operations and large dependencies.
Optimization Recommendations: Provides actionable advice and generates profiling scripts.
Use Case: A developer notices their web application is slow. They run this Skill, which detects it's a Node.js app, sets up clinic doctor, and provides a report highlighting slow API calls and suggesting optimizations.

Quick Start

Run this skill to profile your Node.js application and identify performance bottlenecks.

Frequently Asked Questions about performance-profile

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I find and fix performance bottlenecks in my Node.js application?▼

To find performance bottlenecks in a Node.js application, this skill automatically sets up clinic.js to profile runtime execution, detects slow API calls, and suggests actionable optimizations.

Can I profile Python code to identify slow execution and anti-patterns?▼

Yes, you can profile Python applications using cProfile. The skill detects the Python runtime, generates profiling scripts, and scans your code for anti-patterns like synchronous operations that slow execution.

What's the best way to detect browser application performance issues?▼

The best way to detect browser performance issues is using Lighthouse. This skill sets up the tool automatically to audit your web application and provides token-efficient reporting on bottlenecks.

Do I need to manually install profiling tools before scanning my code?▼

No, you do not need to manually install profiling tools. The skill detects your runtime environment—Node.js, Python, or browser—and handles the automated setup of clinic.js, cProfile, or Lighthouse.

What types of code anti-patterns does performance profiling look for?▼

Performance profiling scans your code to identify common anti-patterns such as synchronous operations and large dependencies that cause software bottlenecks.

Does the performance-profile skill work with both Node.js and Python environments?▼

Yes, the skill works with both Node.js and Python environments, as well as browser applications. It detects the active runtime to apply the correct profiling tool and optimization recommendations.
