Expert-level React development with hooks, performance optimization, state management, and modern patterns
Comprehensive code reviewer for Java and Python implementations focusing on correctness, efficiency, code quality, and algorithmic optimization. Reviews LeetCode solutions, data structures, and algorithm implementations. Use when reviewing code, checking solutions, or providing feedback on implementations.
Provides AWS Lambda integration patterns for Java with cold start optimization. Use when deploying Java functions to AWS Lambda, choosing between Micronaut and Raw Java approaches, optimizing cold starts below 1 second, configuring API Gateway or ALB integration, or implementing serverless Java applications. Triggers include "create lambda java", "deploy java lambda", "micronaut lambda aws", "java lambda cold start", "aws lambda java performance", "java serverless framework".
Advanced token optimization and context management strategies.
Comprehensive guide to the Compact programming language for writing privacy-preserving smart contracts on Midnight Network. Use when users need to write Compact smart contracts with zero-knowledge proofs, understand Compact syntax and language features, implement ZK circuit patterns and optimizations, generate contract boilerplate and project scaffolding, learn best practices for secure contract development, access Compact standard library functions, and compile and test Compact contracts.
Frontend development patterns for React, Next.js, state management, performance optimization, and UI best practices.
When the user wants to analyze website traffic sources, attribution, or dark traffic. Also use when the user mentions "traffic sources," "dark traffic," "direct traffic," "UTM parameters," "traffic attribution," "channel attribution," "attribution optimization," "channel analysis," "traffic analysis," "traffic diversification," "natural traffic benchmark," or "organic vs paid traffic."
Email marketing specialist covering email sequences, newsletters, automation workflows, deliverability, list management, and transactional emails. Use when the user wants to write emails, create drip campaigns, set up welcome sequences, design nurture flows, improve open rates, reduce unsubscribes, plan newsletters, set up email automation, segment audiences, or optimize email deliverability. Also triggers for subject line optimization, email copywriting, A/B testing emails, or ESP selection.
Provides expert guidance for building GraalVM Native Image executables from Java applications. Use when converting JVM applications to native binaries, optimizing cold start times, reducing memory footprint, configuring native build tools for Maven or Gradle, resolving reflection and resource issues in native builds, or implementing framework-specific native support for Spring Boot, Quarkus, and Micronaut. Triggers include "graalvm native image", "native executable java", "java cold start optimization", "native build tools", "ahead of time compilation java", "reflection config graalvm", "native image build failure".
Architecture optimization team skill. Analyzes codebase architecture, designs refactoring plans, implements changes, validates improvements, and reviews code quality via CSV wave pipeline with interactive review-fix cycles.
OpenSearch development best practices for indexing, querying, search optimization, vector search, and cluster management
Analyze VictoriaMetrics query trace JSON to diagnose slow queries and produce a structured performance report with time breakdown, bottleneck analysis, and optimization recommendations. ALWAYS use this skill when: (1) the user mentions a VictoriaMetrics or VM trace, query trace, or trace JSON, (2) the user provides or references a JSON file containing duration_msec/message/children fields, (3) the user asks why a VictoriaMetrics/VM query is slow and has trace output, (4) the user asks about vmstorage node distribution, cache misses, or rollup performance in the context of a trace, (5) the user mentions vmselect trace, trace=1, or query performance debugging with VictoriaMetrics. This skill provides a structured report template that ensures consistent, thorough analysis — do not attempt to analyze VM traces without it.
