Use when working with ANY GPU rendering, Metal, OpenGL migration, shaders, 3D content, RealityKit, AR, or display performance. Covers Metal migration, shader conversion, RealityKit ECS, RealityView, variable refresh rate, ProMotion.
Use these skills when you need to troubleshoot performance bottlenecks, analyze query execution plans, identify resource-heavy processes, and monitor system-level PromQL metrics.
Implements the Syncfusion React Bullet Chart component for KPI and performance indicator visualization. Use this when users need feature measure displays, comparative measures, target comparisons, or metric visualizations. Covers data binding, value bars, target bars, ranges, titles, tooltips, data labels, axis customization, orientation, and accessibility.
Cross-platform mobile development with React Native and Expo. Use when building iOS/Android apps with JavaScript/TypeScript, implementing native features, or optimizing mobile performance.
NestJS best practices and architecture patterns for building production-ready applications. This skill should be used when writing, reviewing, or refactoring NestJS code to ensure proper patterns for modules, dependency injection, security, and performance.
Provides situational playbooks for high-stakes edge cases that don't fit the standard management toolkit — produces step-by-step guidance for inappropriate team behavior, an engineer badmouthing your manager, letting someone go when circumstances are hard, manager quitting guilt, and handling layoffs (for both those leaving and those staying). Use when the user says "don't know how to handle this," "someone said something inappropriate," "engineer said something offensive," "developer talks badly about my manager," "letting someone go when their situation is hard," "I feel guilty about leaving my job," or "handling a layoff." Do NOT use for standard underperformance management (use performance-reviews) or giving direct feedback (use feedback).
Helps engineering managers measure and improve team delivery — produces a history of why common metrics fail, the DORA four-key-metrics framework (deployment frequency, lead time, change failure rate, MTTR), DevEx's three dimensions (feedback loops, cognitive load, flow state), a translation layer from engineering metrics to business outcomes, and a list of measurement anti-patterns to avoid. Use when the user says "how do I measure productivity," "DORA metrics," "velocity," "cycle time," "developer experience," "DevEx," "how do I show our team is performing well," "metrics for engineering," "team is slow," "engineering performance," or "connect engineering to business." Do NOT use for managing an underperforming individual — use performance-reviews instead.
Filter Etsy stores through multiple dimensions (sales volume, favorites, reviews, store opening time, country, main category, Raving/star label, etc.) via the EHunt MCP tool `_ehunt_storeQuery` (display name: "Etsy Store Query"). Trigger this skill when users mention EHunt Etsy stores, Etsy store search, Etsy seller, Etsy store rankings, Etsy weekly sales stores, ehunt stores, Etsy store query, or _ehunt_storeQuery. Even if users don't mention EHunt, this skill should be triggered as long as they are looking for stores on Etsy, filtering store data, or analyzing store performance.
Analyze production Agentforce agent behavior using session traces and Data Cloud. TRIGGER when: user queries STDM session data or Data Cloud trace records; investigates production agent failures, regressions, or performance issues; asks about session traces, conversation logs, or agent metrics; wants to reproduce a reported production issue in preview; runs findSessions or trace analysis queries. DO NOT TRIGGER when: user creates, modifies, or debugs .agent files during development (use developing-agentforce); writes or runs test specs (use testing-agentforce); uses sf agent preview for local development iteration; deploys or publishes agents.
Code Review Expert: Perform in-depth code reviews using context-isolated subagents, covering security vulnerabilities, performance optimizations, and production reliability
Safely inspect, backup, and maintain local Codex state to keep performance fast and clean
Airbnb-DLS-aligned design system engineering for Expo / React Native apps targeting both web and native iOS, built on Unistyles v3, Reanimated, Skia, and FlashList. Use whenever building, reviewing, or refactoring shared UI — design tokens, theming, variant-driven component APIs, typography, spacing, cross-platform web/iOS parity, native-feel performance, or complex surfaces like calendars and drawing canvases (examples use a clinic app). Covers token architecture, theming, component API contracts (variants over style props), web/iOS parity (Unistyles `_web` hover/focus/cursor, Platform splits, one shared theme), the Unistyles styling engine, and governance. Trigger even when the user does not say "design system" but is creating or changing reusable React Native components, tokens, theme code, or making a component behave natively on both web and iOS. Teaches how to BUILD the design system; pair with expo-react-native-coder for features and expo-ios-hig for iOS native-feel decisions.
