Solidity smart contract gas optimization guidelines based on RareSkills. Use when writing, reviewing, or auditing Solidity code. Triggers on tasks involving smart contracts, EVM development, gas optimization, or Solidity best practices.
Ruby Refactoring Expert
by ag0os
Automatically invoked when analyzing code quality, refactoring, or maintainability. Triggers on mentions of "code smell", "refactor", "code quality", "technical debt", "complexity", "maintainability", "clean code", "SOLID", "DRY", "improve code", "simplify", "extract method", "extract class", "long method", "large class", "duplication". Provides Ruby refactoring patterns and code smell identification based on Ruby Science methodology for recently written Ruby/Rails code.
magento-configuration-specialist
by maxnorm
Analyzes and manages Magento 2 system configuration. Use when analyzing configuration, retrieving configuration data, managing system settings, or troubleshooting configuration issues. Masters configuration analysis, system settings, and configuration optimization.
magento-catalog-specialist
by maxnorm
Analyzes and retrieves catalog information from Magento 2. Use when analyzing product catalogs, retrieving catalog data, assessing catalog health, or optimizing catalog performance. Masters catalog structure analysis, product data inspection, and catalog diagnostics.
python-concurrency-performance
by ahgraber
Use when designing or reviewing concurrent Python code — selecting between asyncio, threads, or multiprocessing; structuring cancellation and deadline propagation; bounding fan-out and backpressure. Also use when diagnosing race conditions, deadlocks, slow throughput, or thread/task leaks under load.
backend-dev
by julianromli
Comprehensive backend development workflow that orchestrates expert analysis, architecture design, implementation, and deployment using the integrated toolset. Handles everything from API design and database architecture to security implementation and DevOps automation.
browser
by julianromli
Minimal Chrome DevTools Protocol tools for browser automation and scraping. Use when you need to start Chrome, navigate pages, execute JavaScript, take screenshots, or interactively pick DOM elements.
pmf-survey
by breethomas
Create and analyze a PMF survey using Rahul Vohra's Superhuman framework. The magic 40% benchmark for product-market fit.
prompt-engineering
by breethomas
Expert prompt optimization system for building production-ready AI features. Use when users request help improving prompts, want to create system prompts, need prompt review/critique, ask for prompt optimization strategies, want to analyze prompt effectiveness, mention prompt engineering best practices, request prompt templates, or need guidance on structuring AI instructions. Also use when users provide prompts and want suggestions for improvement.
coreml-optimizer
by ckorhonen
Optimize CoreML models for iOS and macOS deployment. Covers quantization, palettization, pruning, Neural Engine targeting, compute unit selection, and performance profiling. Use when converting ML models to CoreML, optimizing model size/latency, debugging Neural Engine issues, or benchmarking on-device inference.
architecture-serverless
by KentoShimizu
"Serverless architecture workflow for event-driven and bursty workloads using managed compute and platform services. Use when elasticity and reduced platform operations justify managed-service constraints; do not use when workload shape requires long-lived stateful control loops."
db-query-optimization
by KentoShimizu
"Query optimization workflow for reducing latency and resource cost through plan-aware rewrites and access-path improvements. Use when hot-path query behavior is the bottleneck; do not use for conceptual schema redesign without workload evidence."
gather-plan-apply
by mgd34msu
"MANDATORY before starting any task. Enforces the GPA execution loop that prevents tool call sprawl. G: GATHER phase combines discover queries + memory reads + file reads into one phase. P: Plan in text with zero tool calls. A: APPLY all writes/edits/verification in one phase. One call per tool type per phase — batch all same-type operations together. Covers dependency analysis, batch opportunities, scope estimation, and loop-back triggers."
goodvibes-memory
by mgd34msu
"ALWAYS load before starting any task. Provides persistent cross-session memory for learning from past work. Read memory at task start to avoid repeating mistakes; write memory at task end to record what worked. Covers decisions.json (architectural choices), patterns.json (proven approaches), failures.json (past errors and fixes), preferences.json (project conventions), and session activity logs."
prompt-engineering-expert
by TomsTools11
Advanced expert in prompt engineering, custom instructions design, and prompt optimization for AI agents
task-orchestration
by mgd34msu
"Load PROACTIVELY when decomposing a user request into parallel agent work. Use when user says \"build this\", \"implement this feature\", or any request requiring multiple agents working concurrently. Guides task decomposition into parallelizable units, agent assignment with skill matching, dependency graph construction, WRFC loop coordination across up to 6 concurrent agent chains, and result aggregation."
concurrency-patterns
by KentoShimizu
"Design and review concurrency strategy for shared state, coordination, and contention control. Use when parallel execution or async coordination introduces race/deadlock/liveness risk and explicit pattern selection is required; do not use for persistence schema or deployment topology decisions."
performance-audit
by mgd34msu
"Load PROACTIVELY when task involves optimizing speed, reducing bundle size, or improving responsiveness. Use when user says \"make it faster\", \"reduce bundle size\", \"fix slow queries\", \"optimize rendering\", or \"check Core Web Vitals\". Covers bundle analysis and tree-shaking, database query optimization (N+1, indexing), React rendering performance (re-renders, memoization), network waterfall optimization, memory leak detection, server-side performance, and Core Web Vitals (LCP, FID, CLS) improvement."
