Add Performance Analysis Plugin with 5 Specialized Agents

[murali-marimekala]

Overview

Introduces a comprehensive Performance Analysis Plugin for Claude Code that provides specialized agents for identifying performance bottlenecks, analyzing algorithmic complexity, detecting memory issues, validating concurrent code, and recommending practical optimizations.

This plugin addresses a critical gap in Claude Code's feature set by providing developers with robust performance analysis capabilities integrated directly into their workflow.

Problem Statement

Currently, Claude Code lacks dedicated performance analysis features. Developers must:

• Manually identify bottlenecks through profiling or code review
• Lack systematic approaches to complexity analysis
• Miss memory inefficiency patterns
• Struggle to validate concurrent/async code
• Have no integrated optimization guidance

Solution

The Performance Analysis Plugin provides:

3 Commands

• /perf-analyze - Comprehensive multi-agent code performance analysis
• /perf-profile - Deep-dive performance profiling of specific files/functions
• /perf-compare - Performance regression detection between branches

5 Specialized Agents

1. Bottleneck Detective - Identifies code sections with high execution frequency
2. Complexity Analyzer - Calculates Big O complexity and suggests better algorithms
3. Memory Profiler - Detects leaks and inefficient allocations
4. Concurrency Validator - Identifies race conditions and deadlock risks
5. Optimization Recommender - Provides actionable optimization suggestions with code examples

2 Guidance Skills

• Performance Patterns - 10+ common optimization patterns and anti-patterns
• Profiling Tools Guide - Language-specific tools (JS, Python, Java, C#, Go, Rust)

Key Features

✅ High-Signal Analysis - Focuses on real performance issues, not code style
✅ Multi-perspective Review - 5 agents analyze code from different angles
✅ Language-Aware - Recognizes patterns in multiple programming languages
✅ Actionable Findings - Every issue includes concrete optimization suggestions
✅ Severity-Based Filtering - Critical/High/Medium/Low prioritization
✅ PR Integration - Can post findings as PR comments
✅ Comprehensive Training - Includes anti-patterns, tools guide, and best practices

/perf-analyze src/ --threshold high

# Profile specific file for detailed analysis
/perf-profile src/core/engine.ts

# Detect regressions vs main branch
/perf-compare main

# Focus on memory issues in PR changes
/perf-analyze --pr --focus memory

Standards & Compliance

✅ Follows Anthropic's plugin structure and conventions
