llamaindex-patterns
LlamaIndex implementation patterns with templates, scripts, and examples for building RAG applications. Use when implementing LlamaIndex, building RAG pipelines, creating vector indices, setting up query engines, implementing chat engines, integrating LlamaCloud, or when user mentions LlamaIndex, RAG, VectorStoreIndex, document indexing, semantic search, or question answering systems.
share-skill
Push a local skill to the Notion skills database. Load when user mentions "share skill", "export skill", "push to notion", "add skill to database", or after creating a new skill with create-skill.
mermaid-diagrams
Comprehensive guide for creating software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams (domain modeling, object-oriented design), sequence diagrams (application flows, API interactions, code execution), flowcharts (processes, algorithms, user journeys), entity relationship diagrams (database schemas), C4 architecture diagrams (system context, containers, components), state diagrams, git graphs, pie charts, gantt charts, or any other diagram type. Triggers include requests to "diagram", "visualize", "model", "map out", "show the flow", or when explaining system architecture, database design, code structure, or user/application flows.
global-tech-stack
Reference and maintain the project's technical stack documentation including frameworks, languages, databases, testing tools, and third-party services to ensure consistency across all development work. Use this skill when choosing technologies for new features, when documenting technology decisions, when working with framework-specific code patterns, or when ensuring consistency with existing technology choices. Use this skill when working with any code file to verify it follows the conventions of the project's chosen frameworks and tools. Use this skill when setting up new dependencies, configuring build tools, or making architectural decisions about which libraries or services to use. Use this skill when onboarding new team members or creating technical documentation about the project's architecture and technology choices.
test-doctor
Use this skill to diagnose and repair broken tests with a methodical, surgical approach.AUTO-ACTIVATE when user mentions (FR/EN): - test cassé, broken test, failing test, test fail, test échoue - erreur test, test error, assertion failed, timeout test - réparer test, fix test, corriger test, debug test - npm test fail, jest error, test suite failedAGENTS: Specialized agents (backend-specialist, frontend-specialist, database-specialist) MUST invoke this skill when asked to fix tests. Use: Skill("test-doctor")CRITICAL: NO mass corrections. ONE test at a time with validation. ALWAYS diagnose before fixing. ALWAYS consult DONT_DO.md first.Context: 1211 test files, 5561/6101 passing (540 failing). Stack: Jest, React Testing Library, Prisma, Next.js 15, TypeScript 5.
error-annihilator
Elite debugging and error-resolution system optimized for Next.js/TypeScript/Supabase stacks. Use when encountering ANY error, bug, or unexpected behavior including API failures, database issues, build errors, runtime crashes, logic bugs, performance problems, or deployment issues. Specializes in cryptic webpack errors, Supabase RLS policies, vector database mismatches, module resolution, API cascades, and multi-error triage. Provides rapid root cause analysis + ranked solution approaches + explanatory insights. Trigger on error messages, stack traces, "why isn't this working", "something's broken", debugging requests, or troubleshooting needs.
symbols
Token-efficient codebase navigation through intelligent symbol loading and querying. Use this skill when implementing new features (find existing patterns), exploring codebase structure, searching for components/functions/types, or understanding architectural layers. Reduces token usage by 60-95% compared to loading full files. Layer split enables 50-80% additional backend efficiency.
redis
Redis caching, pub/sub, and data structures. Activate for Redis operations, caching strategies, session management, and message queuing.
notion-uploader-downloader
Bidirectional sync between Markdown and Notion. Upload .md files with images to Notion pages/databases, append to existing pages, or download Notion content back to markdown. Supports rich formatting, tables, code blocks, GitHub-flavored markdown, and recursive page hierarchy downloads with YAML frontmatter for round-trip sync.
project-scaffolder
프론트엔드 프로젝트 구조를 분석하고 정리하여 AI 에이전트가 활용할 수 있는 컨텍스트 문서를 생성하는 스킬. "프로젝트 구조 잡아줘", "폴더 구조 정리해줘", "아키텍처 문서화해줘", "프로젝트 초기 설정해줘" 등의 요청에 트리거된다. Next.js, Supabase, React 등 다양한 프론트엔드 스택에서 범용적으로 사용 가능하다.
cve-search
Searches the NIST NVD database for CVE vulnerabilities using API 2.0. Returns CVE details, CVSS scores, affected software, and references. Use when user asks about "CVE", "vulnerability database", "NIST", "NVD", "security advisory", "CVE-2024", "CVE-2023", "脆弱性", "セキュリティアドバイザリ", or wants to find known vulnerabilities for specific software.
container-best-practices
Expert guidance on dockerfile optimization, multi-stage builds, layer caching strategies, and base image selection. Activates when working with "dockerfile", "docker-compose", "multi-stage", "container optimization", "image layers", or "build cache".
applying-personas
Apply expert personas to provide specialized feedback and perspectives. Use when you want feedback through the lens of specific experts, critics, or archetypes (e.g., "give me feedback as a focused product manager" or "review this as Jason Fried would").
