This skill automates the setup of synthetic monitoring for applications. It allows Claude to proactively track performance and availability by configuring uptime, transaction, and API monitoring. Use this skill when the user requests to "set up synthetic monitoring", "configure uptime monitoring", "track application performance", or needs help with "proactive performance tracking". The skill helps to identify critical endpoints and user journeys, design monitoring scenarios, and configure alerts and dashboards.

This skill enables Claude to analyze logs for performance insights and issue detection. It is triggered when the user requests log analysis, performance troubleshooting, or debugging assistance. The skill identifies slow requests, error patterns, resource warnings, and other key performance indicators within log files. Use this skill when the user mentions "analyze logs", "performance issues", "error patterns in logs", "slow requests", or requests help with "log aggregation". It helps identify performance bottlenecks and improve application stability by analyzing log data.

Use when profiling native macOS or iOS apps with Instruments/xctrace. Covers correct binary selection, CLI arguments, exports, and common gotchas.

This skill enables Claude to manage database schema changes through version-controlled migrations. It is activated when the user requests to create, apply, or rollback database migrations. The skill supports generating timestamped migration files with both up and down migrations for PostgreSQL, MySQL, SQLite, and MongoDB. It helps in tracking schema evolution and ensuring safe database modifications. Use this skill when the user mentions "database migration", "schema change", "add column", "rollback migration", or "create migration".

This skill enables Claude to scan container images and running containers for vulnerabilities using tools like Trivy and Snyk. It identifies potential security risks in container environments. Use this skill when the user requests a security assessment of a container image, asks to identify vulnerabilities in a container, or wants to improve the security posture of their containerized applications. Trigger terms include "scan container," "container security," "vulnerability assessment," "Trivy scan," or "Snyk scan."

Use when the user mentions Exa research OR when the workflow benefits from complex, multi-step research and other exa-ai approaches are not yielding satisfactory results.

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.

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.

Working with Terraform configuration, CLI, modules, and providers. Use when writing or reviewing HCL configuration, managing infrastructure as code, debugging Terraform plans/applies, or working with Terraform-related tools.

This skill enables Claude to generate Helm charts for Kubernetes applications. It should be used when the user requests the creation of a new Helm chart, the modification of an existing chart, or assistance with packaging and deploying Kubernetes applications using Helm. The skill is triggered by requests that mention "Helm chart", "Kubernetes deployment", "package application for Kubernetes", or similar phrases related to Helm and Kubernetes. It helps streamline the process of creating and managing Kubernetes deployments.

This skill enables Claude to analyze logs for performance insights and issue detection. It is triggered when the user requests log analysis, performance troubleshooting, or debugging assistance. The skill identifies slow requests, error patterns, resource warnings, and other key performance indicators within log files. Use this skill when the user mentions "analyze logs", "performance issues", "error patterns in logs", "slow requests", or requests help with "log aggregation". It helps identify performance bottlenecks and improve application stability by analyzing log data.

Your approach to handling global atomic design. Use this skill when working on files where global atomic design comes into play.

Comprehensive guide for implementing Fullstory's User Identification API (setIdentity) across web applications. Teaches proper uid handling, property passing, re-identification behavior, and session management. Includes detailed good/bad examples for login flows, multi-account scenarios, and SPA applications to help developers correctly identify users for analytics and session replay.

Implements production code for PHP/CakePHP applications based on functional design specifications

Create and (optionally) merge a GitHub pull request (prefer GitHub chat tools; gh/wrappers are fallback), following the repo policy to use rebase and merge for a linear history.

Systematically enumerate how code can fail to prevent claiming safety without evidence. Use when: (1) asked to identify failure modes, enumerate risks, or stress-test reliability assumptions, (2) code is characterized as safe or production-ready without enumerated failure scenarios, (3) a code review covers only successful execution paths, (4) changes are ready for approval without failure analysis, (5) code lacks input validation, error handling, or defensive checks, (6) test coverage includes only successful cases.

Repository structure and dependency analysis for understanding a codebase's architecture. Use when needing to (1) generate a file tree or structure map, (2) analyze import/dependency graphs, (3) identify entry points and module boundaries, (4) understand the overall layout of an unfamiliar codebase, or (5) prepare for deeper architectural analysis.
