tracking-resource-usage

This skill enables Claude to track and optimize resource usage across an application stack. It is activated when the user requests insights into resource consumption, performance bottlenecks, or cost optimization opportunities. The skill uses the resource-usage-tracker plugin to monitor CPU, memory, disk I/O, network I/O, file descriptors, database connections, and thread/process counts. Use this skill when the user mentions "resource usage", "performance optimization", "cost optimization", "track resources", or "right-sizing".

analyzing-network-latency

This skill enables Claude to analyze network latency and optimize request patterns within an application. It helps identify bottlenecks and suggest improvements for faster and more efficient network communication. Use this skill when the user asks to "analyze network latency", "optimize request patterns", or when facing performance issues related to network requests. It focuses on identifying serial requests that can be parallelized, opportunities for request batching, connection pooling improvements, timeout configuration adjustments, and DNS resolution enhancements. The skill provides concrete suggestions for reducing latency and improving overall network performance.

running-load-tests

This skill enables Claude to create and execute load tests for performance validation. It is designed to generate load test scripts using tools like k6, JMeter, and Artillery, based on specified test scenarios. Use this skill when the user requests to create a "load test", conduct "performance testing", validate "application performance", or needs a "stress test" to identify breaking points in the application. The skill helps define performance thresholds and provides execution instructions.

collecting-infrastructure-metrics

This skill enables Claude to collect comprehensive infrastructure performance metrics across compute, storage, network, containers, load balancers, and databases. It is triggered when the user requests "collect infrastructure metrics", "monitor server performance", "set up performance dashboards", or needs to analyze system resource utilization. The skill configures metrics collection, sets up aggregation, and helps create infrastructure dashboards for health monitoring and capacity tracking. It supports configuration for Prometheus, Datadog, and CloudWatch.

analyzing-capacity-planning

This skill enables Claude to analyze capacity requirements and plan for future growth. It uses the capacity-planning-analyzer plugin to assess current utilization, forecast growth trends, and recommend scaling strategies. Use this skill when the user asks to "analyze capacity", "plan for growth", "forecast infrastructure needs", or requests a "capacity roadmap". It is also useful when the user mentions specific capacity metrics like CPU usage, memory, database storage, network bandwidth, or connection pool saturation. This skill is ideal for proactive infrastructure planning and preventing performance bottlenecks.

profiling-application-performance

This skill enables Claude to profile application performance, analyzing CPU usage, memory consumption, and execution time. It is triggered when the user requests performance analysis, bottleneck identification, or optimization recommendations. The skill uses the application-profiler plugin to identify performance bottlenecks and suggest code-level optimizations. Use it when asked to "profile application", "analyze performance", or "find bottlenecks". It is also helpful when the user mentions specific performance metrics like "CPU usage", "memory leaks", or "execution time".

creating-apm-dashboards

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.

creating-alerting-rules

This skill enables Claude to create intelligent alerting rules for proactive performance monitoring. It is triggered when the user requests to "create alerts", "define monitoring rules", or "set up alerting". The skill helps define thresholds, routing, and escalation policies, and offers options for multi-category alert creation, including latency, error rate, throughput, resource utilization, availability, and SLO violation alerts. It is useful for Site Reliability Engineers (SREs) and DevOps teams looking to improve system observability.

performing-security-code-review

This skill enables Claude to conduct a security-focused code review using the security-agent plugin. It analyzes code for potential vulnerabilities like SQL injection, XSS, authentication flaws, and insecure dependencies. Claude uses this skill when the user explicitly requests a security audit, asks for a code review with a focus on security, or mentions security concerns related to code. The security-agent plugin then provides structured security findings with severity ratings, code locations, impact assessments, and remediation guidance.

managing-autonomous-development

Enables Claude to manage Sugar's autonomous development workflows. It allows Claude to create tasks, view the status of the system, review pending tasks, and start autonomous execution mode. Use this skill when the user asks to create a new development task using `/sugar-task`, check the system status with `/sugar-status`, review pending tasks via `/sugar-review`, or initiate autonomous development using `/sugar-run`. It provides a comprehensive interface for interacting with the Sugar autonomous development system.

creating-kubernetes-deployments

This skill enables Claude to generate Kubernetes deployment manifests, services, and related configurations following best practices. It should be used when the user asks to create a new Kubernetes deployment, service, ingress, or other related resources. Claude will generate YAML files for Deployments, Services, ConfigMaps, Secrets, Ingress, and Horizontal Pod Autoscalers. Use this skill when the user mentions "Kubernetes deployment", "K8s deployment", "create service", "define ingress", or asks for a manifest for any K8s resource.

generating-infrastructure-as-code

This skill enables Claude to generate Infrastructure as Code (IaC) configurations. It uses the infrastructure-as-code-generator plugin to create production-ready IaC for Terraform, CloudFormation, Pulumi, ARM Templates, and CDK. Use this skill when the user requests IaC configurations for cloud infrastructure, specifying the platform (e.g., Terraform, CloudFormation) and cloud provider (e.g., AWS, Azure, GCP), or when the user needs help automating infrastructure deployment. Trigger terms include: "generate IaC", "create Terraform", "CloudFormation template", "Pulumi program", "infrastructure code".
