Performance Optimization Guide

optimizing-performance

CloudAI-X/claude-workflow-v2

Provides a structured workflow to analyze and improve application performance across frontend, backend, and database layers, including profiling, bottleneck identification, optimization tactics, and validation steps.

SQL Query Optimization

optimizing-sql-queries

jeremylongshore/claude-code-plugins-plus-skills

Analyzes SQL statements, identifies bottlenecks, suggests indexes and rewrites, and leverages the sql-query-optimizer plugin so you can improve database responsiveness when queries run slowly.

Performance Testing Automation

performance-testing

jeremylongshore/claude-code-plugins-plus-skills

Automates load, stress, spike, and endurance tests through the performance-test-suite plugin, collecting response time, throughput, and error-rate metrics to spot CPU/memory/database/network bottlenecks and deliver graphs plus optimization guidance.

Supabase Postgres Best Practices Guide

postgres-best-practices

sickn33/antigravity-awesome-skills

A comprehensive resource providing best practices for PostgreSQL performance optimization, schema design, and security configuration. Developed by Supabase, it covers critical areas like query performance, connection management, and Row-Level Security. Use this skill when writing complex SQL queries, reviewing schema integrity, or diagnosing database bottlenecks to ensure high performance and stability.

PostHog Rate Limits

posthog-rate-limits

jeremylongshore/claude-code-plugins-plus-skills

Guides on handling PostHog rate limits with exponential backoff, jitter, idempotent keys, queuing, and header monitoring to keep API calls reliable during throttling or retry scenarios.

Batch API Processing

processing-api-batches

jeremylongshore/claude-code-plugins-plus-skills

Defines a batch-processing pattern for APIs that validates payloads, runs synchronous or async execution with concurrency limits, tracks per-item progress, reports partial failures, and integrates retries and throttling for large bulk operations.

Application Performance Profiling

profiling-application-performance

jeremylongshore/claude-code-plugins-plus-skills

Profiles application performance by analyzing CPU usage, memory allocation, and execution time with the application-profiler plugin, then identifies bottlenecks and suggests code-level optimizations for faster execution.

Performance Optimization Advisor

providing-performance-optimization-advice

jeremylongshore/claude-code-plugins-plus-skills

Provides prioritized performance optimization recommendations across frontend, backend, and infrastructure, offering bottleneck analysis, impact estimates, and phased implementation roadmaps when users request speed improvements or reviews.

Replit Rate Limit Guard

replit-rate-limits

jeremylongshore/claude-code-plugins-plus-skills

Provides Replit-specific rate limiting guidance, adding exponential backoff with jitter, deterministic idempotency keys, queue throttling, and header monitoring so apps stay within quotas while retrying safely.

Retell AI Rate Limits

retellai-rate-limits

jeremylongshore/claude-code-plugins-plus-skills

Provides Retell AI clients with structured rate limit handling by combining exponential backoff with jitter, idempotent request keys, header monitoring, and optional queueing so retries stay safe when 429 or limit headers indicate throttling.

Performance Test Suite

running-performance-tests

jeremylongshore/claude-code-plugins-plus-skills

Guides systematic load, stress, spike, and soak testing with k6, Artillery, JMeter, Locust, or autocannon, producing SLA-aligned metrics, bottleneck analysis, and CI gates for production-like services.

Sentry Performance Tracing

sentry-performance-tracing

jeremylongshore/claude-code-plugins-plus-skills

Configure Sentry to monitor application performance, enable distributed tracing, and visualize spans so teams can identify bottlenecks and validate that requests propagate through services as expected.
