command-profile

A Claude Code slash command for performance profiling and optimization suggestions.

Installation

# Clone to your preferred location
git clone git@github.com:claude-commands/command-profile.git <clone-path>/command-profile

# Symlink (use full path to cloned repo)
ln -s <clone-path>/command-profile/profile.md ~/.claude/commands/profile.md

Usage

/profile                      # Find performance issues in project
/profile src/api/users.ts     # Profile specific file
/profile handleRequest        # Profile specific function
/profile --memory             # Focus on memory usage
/profile --cpu                # Focus on CPU hotspots

What it does

1. Detects language and profiling tools
2. Identifies slow functions and hotspots
3. Analyzes complexity and patterns
4. Generates optimization suggestions
5. Creates benchmarks for comparison

Output Format

# Performance Profile

## Hotspots Identified
1. getUserWithPosts (Line 45)
   - Issue: N+1 query pattern
   - Fix: Use JOIN or batch loading
   - Impact: 10x improvement

## Memory Concerns
| Function | Allocations |
| -------- | ----------- |
| loadAllUsers | 45/call |

## Recommendations
1. Fix N+1 queries
2. Add caching layer
