Performance profiling and optimization
team-polish
by Donchitos
"Orchestrate the polish team: coordinates performance-analyst, technical-artist, sound-designer, and qa-tester to optimize, polish, and harden a feature or area for release quality."
react-devtools
by piotrski
React DevTools CLI for AI agents. Use when the user asks you to debug a React or React Native app at runtime, inspect component props/state/hooks, diagnose render performance, profile re-renders, find slow components, or understand why something re-renders. Triggers include "why does this re-render", "inspect the component", "what props does X have", "profile the app", "find slow components", "debug the UI", "check component state", "the app feels slow", or any React runtime debugging task.
vm-create
by RHEcosystemAppEng
Create new virtual machines in OpenShift Virtualization with automatic instance type resolution and OS selection. Use this skill when users request: - "Create a new VM" - "Deploy a virtual machine with [OS]" - "Set up a VM in namespace [name]" - "Provision a [size] VM" This skill handles VM creation with intelligent defaults for OpenShift Virtualization. NOT for managing existing VMs (use vm-lifecycle-manager or vm-delete instead).
vm-rebalance
by RHEcosystemAppEng
Orchestrate VM migrations across cluster nodes for load balancing, maintenance, and resource optimization. Use when: - "Move VM database-01 to worker-03" - "Rebalance VMs to optimize CPU load" - "Drain worker-02 for maintenance" - "Automatically rebalance the cluster" Supports Manual (user-driven) and Automatic (AI-driven) modes. NOT for creating VMs (use vm-create) or lifecycle only (use vm-lifecycle-manager).
deep-review
by coder
Sub-agent powered code reviews spanning correctness, tests, consistency, and fit
content-strategist

Code Cleanup Skill
by pipecat-ai
Pattern checks follow recent Pipecat code
ccs-delegation
by kaitranntt
Auto-activate CCS CLI delegation for deterministic tasks. Parses user input, auto-selects optimal profile (glm/kimi/custom) from ~/.ccs/config.json, enhances prompts with context, executes via ccs {profile} -p "task" or ccs {profile}:continue, and reports results. Triggers on "use ccs [task]" patterns, typo/test/refactor keywords. Excludes complex architecture, security-critical code, performance optimization, breaking changes.
nav-graph
by alekspetrov
Query project knowledge graph. Search across tasks, SOPs, memories, and concepts. Use when user asks "what do we know about X?", "show everything related to X", or "remember this pattern/pitfall/decision".
surprise-me
by bytedance
Create a delightful, unexpected "wow" experience for the user by dynamically discovering and creatively combining other enabled skills. Triggers when the user says "surprise me" or any request expressing a desire for an unexpected creative showcase. Also triggers when the user is bored, wants inspiration, or asks for "something interesting".
gate-check
by Donchitos
"Validate readiness to advance between development phases. Produces a PASS/CONCERNS/FAIL verdict with specific blockers and required artifacts."
vercel-react-best-practices
by Significant-Gravitas
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
learning-log
by codewithmukesh
Auto-document insights and discoveries during development sessions. Unlike MEMORY.md (corrective rules from the self-correction-loop skill), the learning log captures organic discoveries: non-obvious bugs, undocumented architecture decisions, performance findings, workarounds, and gotchas. Stored at .claude/learning-log.md. Load this skill when Claude discovers something non-obvious, finds a workaround, uncovers an undocumented decision, or when the user asks about "learnings", "discoveries", "gotchas", "what did we learn", or "document this finding".
extreme-software-optimization
by pedronauck
Profile-driven performance optimization with behavior proofs. Use when: optimize, slow, bottleneck, hotspot, profile, p95, latency, throughput, or algorithmic improvements.
unsafe-checker
by actionbook
"CRITICAL: Use for unsafe Rust code review and FFI. Triggers on: unsafe, raw pointer, FFI, extern, transmute, *mut, *const, union, #[repr(C)], libc, std::ffi, MaybeUninit, NonNull, SAFETY comment, soundness, undefined behavior, UB, safe wrapper, memory layout, bindgen, cbindgen, CString, CStr, 安全抽象, 裸指针, 外部函数接口, 内存布局, 不安全代码, FFI 绑定, 未定义行为"
researchers-biographical
by bitwize-music-studio
Researches personal backgrounds, interviews, motivations, and humanizing details. Use when research needs biographical context about people involved in the album's subject.
csharp-developer
by Jeffallan
"Use when building C# applications with .NET 8+, ASP.NET Core APIs, or Blazor web apps. Invoke for Entity Framework Core, minimal APIs, async patterns, CQRS with MediatR."
golang-pro
by Jeffallan
Use when building Go applications requiring concurrent programming, microservices architecture, or high-performance systems. Invoke for goroutines, channels, Go generics, gRPC integration.
google-cloud-waf-cost-optimization
by google
Generates cost optimization guidance for Google Cloud workloads based on the Google Cloud Well-Architected Framework (WAF). Use this skill to evaluate a workload, identify cost requirements and constraints, and provide actionable recommendations for build, deploy, and manage the workload cost-efficiently in Google Cloud.
vercel-react-best-practices
by guanyang
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
self-correction-loop
by codewithmukesh
Self-improving correction capture system. After ANY user correction, detect it, generalize the lesson, and store it as a reusable rule in MEMORY.md. Ensures Claude's mistake rate drops over time by compounding corrections into permanent knowledge. Load this skill when a user corrects Claude's output, mentions "remember this", "don't do that again", "learn from mistakes", "update memory", or when starting a new session (to review existing rules).
