React performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React code to ensure optimal performance patterns. Triggers on tasks involving React components, data fetching, bundle optimization, or performance improvements.
Understand business logic vulnerabilities in AI code including race conditions, integer overflow, and calculation errors that pass functional tests but create security holes. Use this skill when you need to learn about race conditions in AI code, understand integer overflow vulnerabilities, recognize business logic security flaws, or identify calculation errors. Triggers include "race conditions", "business logic vulnerabilities", "integer overflow", "race condition AI", "flash sale security", "concurrent access", "negative totals", "calculation errors".
Use when encountering any bug, test failure, or unexpected behavior in Flutter - requires systematic investigation before proposing fixes
Bewertet Views auf iOS und Android nach Accessibility, Code-Qualität, Test-Coverage und UX/Layout. Erstellt automatisch Tickets für kritische Findings. Aktiviere diesen Skill wenn der User nach View-Qualitätsprüfung, View-Review, Accessibility-Check einer View, oder Cross-Platform-Konsistenz fragt.
Verify performance implications were considered and no obvious anti-patterns exist. Issues result in WARNINGS.
Develop advanced debugging workflows for concurrent rendering, including reproducibility under non-deterministic scheduling.
触发并汇总预览结果(Java转发到Node Preview),输出预览链接与渲染耗时/错误快照。用户要预览或验收预览时调用。
Use when analyzing YouTube videos for research, learning, or understanding how content relates to a project - downloads transcripts with yt-dlp, chunks long content, and provides context-aware analysis
Analyses and optimises performance across frontend, backend and database interactions. Identifies bottlenecks and implements solutions to enhance speed and efficiency.
Search reference OS source code online (Linux, xv6, seL4, MINIX3, Fuchsia/Zircon, FreeBSD). Use when looking up implementation patterns, understanding how production or teaching OSes handle specific features, or finding reference code for scheduler, memory management, IPC, drivers, syscalls.
CodeQL suppressions, security vulnerability troubleshooting, and security best practices
A Windows screenshot skill that provides both programmatic full-screen capture and interactive region selection.
Run and manage performance benchmarks with cargo xtask bench for facet-json, analyzing results with Markdown reports and comparing against serde_json baseline
Detects type confusion vulnerabilities by identifying unsafe type casts, vtable corruption, and polymorphism issues. Use when analyzing object-oriented code, type casting, or investigating C++ memory safety issues.
Detects use-after-free vulnerabilities by identifying pointer dereferences after memory deallocation. Use when analyzing memory management, cleanup code, or investigating dangling pointer issues.
This skill should be used when users need to capture screenshots of web pages. It supports full-page screenshots, viewport-specific captures, responsive screenshots across multiple device sizes, and element-specific screenshots. Use this skill for visual testing, documentation, design reviews, or any task requiring automated browser screenshots.
Three.js lighting - light types, shadows, environment lighting. Use when adding lights, configuring shadows, setting up IBL, or optimizing lighting performance.
Detects arbitrary write vulnerabilities by identifying unchecked array indexing and out-of-bounds memory writes. Use when analyzing memory write operations, pointer arithmetic, or investigating code execution vulnerabilities.
Master Go concurrency with goroutines, channels, sync primitives, and context. Use when building concurrent Go applications, implementing worker pools, or debugging race conditions.
Systematic backward tracing through call chains to find where bugs originate. Triggers on debug, trace, root cause, call stack, error, exception, bug, investigate, find the source, test pollution, flaky test, bisect, why is this failing, where does this come from, track down. Integrates with mcp__zen__debug for hypothesis-driven investigation.
Unified observability for the .NET 8 WPF widget host app - logging, telemetry, health checks, diagnostics exports, and operational tooling. Use when configuring Serilog, Application Insights, health checks, correlation IDs, or support tools.
Use when analyzing code for performance bottlenecks, optimizing slow queries, reducing memory usage, or improving application speed. Identifies N+1 queries, inefficient algorithms, and caching opportunities.
