Structured approach to workplace conflicts, performance discussions, and challenging feedback using preparation-delivery-followup framework. Use when preparing for tough conversations, addressing conflicts, giving critical feedback, or navigating sensitive workplace discussions.

This skill enables Claude to analyze and improve application caching strategies. It optimizes cache hit rates, TTL configurations, cache key design, and invalidation strategies. Use this skill when the user requests to "optimize cache performance", "improve caching strategy", "analyze cache hit rate", or needs assistance with "cache key design", "TTL optimization", or "cache invalidation". The skill identifies potential bottlenecks and recommends adjustments for improved performance and efficiency of caching mechanisms like Redis.

This skill enables cross-browser compatibility testing for web applications using BrowserStack, Selenium Grid, or Playwright. It tests across Chrome, Firefox, Safari, and Edge, identifying browser-specific bugs and ensuring consistent functionality. It is used when a user requests to "test browser compatibility", "run cross-browser tests", or uses the `/browser-test` or `/bt` command to assess web application behavior across different browsers and devices. The skill generates a report detailing compatibility issues and screenshots for visual verification. Activates when you request "conducting browser compatibility tests" functionality.

Master high-performance rendering for large datasets with Datashader. Use this skill when working with datasets exceeding 100M+ points, optimizing visualization performance, or implementing efficient rendering strategies with rasterization and colormapping techniques.

This skill optimizes deep learning models using various techniques. It is triggered when the user requests improvements to model performance, such as increasing accuracy, reducing training time, or minimizing resource consumption. The skill leverages advanced optimization algorithms like Adam, SGD, and learning rate scheduling. It analyzes the existing model architecture, training data, and performance metrics to identify areas for enhancement. The skill then automatically applies appropriate optimization strategies and generates optimized code. Use this skill when the user mentions "optimize deep learning model", "improve model accuracy", "reduce training time", or "optimize learning rate".

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

Generate comprehensive tests for architectural layers with coverage-first analysis.Use when testing specific layers (core, domain, application, infrastructure, boundary).Reads testing strategy from playbook or uses interactive template selection.

Design architecture for Ark features following existing patterns and principles. Use when planning new features, extending components, or evaluating technical approaches.

Create and manage changelog entries. Use when adding changelog entries, finishing features or bugfixes, documenting changes, writing release notes, working in changelog/ directories, wrapping up commits and PRs, or cutting a release.
