This skill enables Claude to create Application Performance Monitoring (APM) dashboards. It is triggered when the user requests the creation of a new APM dashboard, monitoring dashboard, or a dashboard for application performance. The skill helps define key metrics and visualizations for monitoring application health, performance, and user experience across multiple platforms like Grafana and Datadog. Use this skill when the user needs assistance setting up a new monitoring solution or expanding an existing one. The plugin supports the creation of dashboards focusing on golden signals, request metrics, resource utilization, database metrics, cache metrics, business metrics, and error tracking.

Expert guidance for Sparze ECS apps including systems, queries, components, resources, events, and performance trade-offs.

This skill enables Claude to detect and resolve performance bottlenecks in applications. It analyzes CPU, memory, I/O, and database performance to identify areas of concern. Use this skill when you need to diagnose slow application performance, optimize resource usage, or proactively prevent performance issues. The skill is triggered by requests to "detect bottlenecks", "analyze performance", "find performance issues", or similar phrases related to performance optimization. It helps uncover root causes and suggest remediation strategies.

TMDB (The Movie Database) API integration for React Native TV streaming apps. Use when users need help with movie/TV show data, poster images, search functionality, trending content, video trailers from TMDB, API authentication, rate limiting, or TypeScript types for TMDB responses.

This skill automates database backups using the database-backup-automator plugin. It creates scripts for scheduled backups, compression, encryption, and restore procedures across PostgreSQL, MySQL, MongoDB, and SQLite. Use this when the user requests database backup automation, disaster recovery planning, setting up backup schedules, or creating restore procedures. The skill is triggered by phrases like "create database backup", "automate database backups", "setup backup schedule", or "generate restore procedure".

Frontend development guidelines for React/TypeScript applications. Modern patterns including Suspense, lazy loading, useSuspenseQuery, file organization with features directory, styling best practices, routing, performance optimization, and TypeScript best practices. Use when creating components, pages, features, fetching data, styling, routing, or working with frontend code.

This skill enables Claude to detect and resolve performance bottlenecks in applications. It analyzes CPU, memory, I/O, and database performance to identify areas of concern. Use this skill when you need to diagnose slow application performance, optimize resource usage, or proactively prevent performance issues. The skill is triggered by requests to "detect bottlenecks", "analyze performance", "find performance issues", or similar phrases related to performance optimization. It helps uncover root causes and suggest remediation strategies.

Process and implement code review feedback systematically. Use when user provides reviewer comments, PR feedback, code review notes, or asks to implement suggestions from reviews. Activates on phrases like "implement this feedback", "address review comments", or when user pastes reviewer notes.

Detect dangerous operations in database migrations before deployment

This skill enables Claude to detect potential memory leaks and analyze memory usage patterns in code. It is triggered when the user requests "detect memory leaks", "analyze memory usage", or similar phrases related to memory leak detection and performance analysis. The skill identifies potential issues such as unremoved event listeners, closures preventing garbage collection, uncancelled timers, unbounded cache growth, circular references, detached DOM nodes, and unnecessary global state accumulation. It then provides detailed fix recommendations. Use this skill to proactively identify and resolve memory leaks, improving application performance and stability.

This skill enables Claude to monitor database health using real-time metrics, predictive alerts, and automated remediation. It's designed for production-grade database health monitoring for PostgreSQL and MySQL, detecting performance degradation, resource exhaustion, and replication issues. Use this skill when the user requests to monitor database health, check database performance, receive database alerts, or automate database remediation. The skill is triggered by phrases like "check database health", "monitor database performance", "database health check", or "/health-check".

Automatically manages PostgreSQL backups with pgBackRest and Wasabi S3 storage when working with FairDB databases

Complete workflow for evaluating implementation plans before execution with quality checklist and structured feedback

This skill automates security vulnerability testing. It is triggered when the user requests security assessments, penetration tests, or vulnerability scans. The skill covers OWASP Top 10 vulnerabilities, SQL injection, XSS, CSRF, authentication issues, and authorization flaws. Use this skill when the user mentions "security test", "vulnerability scan", "OWASP", "SQL injection", "XSS", "CSRF", "authentication", or "authorization" in the context of application or API testing.

This skill optimizes database connection pooling for enhanced performance and resource management. It is activated when the user requests assistance with connection pooling, database performance tuning, or connection lifecycle management. Use this skill to implement and configure connection pools in various programming languages, identify optimal pool settings, and troubleshoot common connection-related issues. The skill is triggered by phrases like "connection pooling," "optimize database connections," or "improve database performance with connection pool."

This skill automates database archival processes. It helps reduce primary database size by moving historical records to archive tables or cold storage solutions like S3, Azure Blob, or GCS. The plugin supports PostgreSQL and MySQL, implementing automated retention policies, compression, compliance tracking, and zero-downtime migration. Use this when the user mentions "database archival", "archive old database records", "retention policies", "cold storage", or "reduce database size." It is particularly useful for handling requests related to data lifecycle management and compliance requirements in database systems.
