cpp-core-guidelines
by Ariaszzzhc
C++ Core Guidelines by Stroustrup and Sutter for writing modern, safe, and efficient C++ code. Use when writing, reviewing, or refactoring C++ code to ensure type safety, resource safety, and performance. Triggers on C++ code tasks including interface design, resource management (memory, handles, locks), class design, error handling, concurrency, templates, and general code review. Use for questions like "review this C++ code", "how should I manage resources in C++", "best practices for C++ interfaces", or when writing any C++ code that should follow modern standards (C++11/14/17/20).
Builder Operating Model
by Coowoolf
Shift from rigid roles (PM, Designer, Engineer) towards a model where individuals use AI to bridge skill gaps, enabling smaller and flatter teams. Use in early-stage startups or innovation units where speed is critical.
react-agent
by Eva813
Pragmatic React development focused on avoiding over-engineering, effective state management, and render optimization. Use when building React components or features where you need clear guidance on (1) choosing appropriate state management solutions, (2) optimizing component rendering and performance, (3) avoiding common over-engineering patterns, (4) implementing TypeScript with React, or (5) making architectural decisions that balance simplicity with scalability.

Performance patterns for Apollo caching, Redis, and CloudFront optimization
Hierarchy of Engagement
by Coowoolf
A three-level framework to gauge growth quality. Level 1: Core Action completion. Level 2: Retention via accruing benefits and mounting loss. Level 3: Self-perpetuating loops. Don't optimize for MAU—optimize for engaged users.
mobile-design
by liuchiawei
Mobile-first design and engineering doctrine for iOS and Android apps. Covers touch interaction, performance, platform conventions, offline behavior, and mobile-specific decision-making. Teaches principles and constraints, not fixed layouts. Use for React Native, Flutter, or native mobile apps.

simulate-elite-experts
by ooooooooooooooooooop
Simulate high-stakes reasoning by modeling how top experts in the relevant domain would think, disagree, and converge on a decision. Use when users ask to role-play strongest minds, compare elite viewpoints, or ask: what would be a good group of people to explore X, and what would they say. Trigger for prompts like "think like world-class experts", "simulate top domain specialists", "role-play strongest domain people", and "use four-lens dialogue".
global-speed-checker
by openstatusHQ
Run global performance checks on HTTP endpoints from multiple regions worldwide. Use when users want to check speed, latency, performance, or test endpoints globally.
schengen-visa-helper
by 0xhardman
Schengen tourism visa (single applicant) preparation and pre-check assistant. Guides users step by step from onboarding to final review. Works with any Schengen country - user provides their consulate's checklist and application form. Triggers on "check my visa materials", "prepare visa", "Schengen visa", "pre-check", "visa precheck", "review my materials", or any Schengen visa material task. Users with all materials ready can jump directly to Phase 6 review by saying "check my visa materials" or "pre-check".
go-performance
by jovermier
Go performance optimizations including memory allocation reduction, efficient string building, I/O operations, and resource pooling. Use when optimizing Go code for speed or memory efficiency.

session-checkpoint
by guardzcom
This skill should be used when the user says "save checkpoint", "checkpoint", "continue", "resume", "resume work", "save my progress", "clear checkpoint", or "clear all checkpoints". Saves and resumes named session checkpoints to preserve progress across Claude Code sessions. Tracks accomplishments, failed approaches, and modified files. IMPORTANT: When the user says bare "continue" or "resume" at session start and MEMORY.md lists active checkpoints, always invoke this skill.
go-performance-best-practices
