Expert guidance for Domain-Driven Design architecture and implementation. Use when designing complex business systems, defining bounded contexts, structuring domain models, choosing between modular monolith vs microservices, implementing aggregates/entities/value objects, or when users mention "DDD", "domain-driven design", "bounded context", "aggregate", "domain model", "ubiquitous language", "event storming", "context mapping", "domain events", "anemic domain model", strategic design, tactical patterns, or domain modeling. Helps make architectural decisions, identify subdomains, design aggregates, and avoid common DDD pitfalls.

Manage Model Context Protocol (MCP) servers - discover, analyze, and execute tools/prompts/resources from configured MCP servers. Use when working with MCP integrations, need to discover available MCP capabilities, filter MCP tools for specific tasks, execute MCP tools programmatically, access MCP prompts/resources, or implement MCP client functionality. Supports intelligent tool selection, multi-server management, and context-efficient capability discovery. | Sử dụng khi: quản lý MCP, tool server, kết nối external tools.

Designs digital experiences for ADHD brains using neuroscience research and UX principles. Expert in reducing cognitive load, time blindness solutions, dopamine-driven engagement, and compassionate design patterns. Activate on 'ADHD design', 'cognitive load', 'accessibility', 'neurodivergent UX', 'time blindness', 'dopamine-driven', 'executive function'. NOT for general accessibility (WCAG only), neurotypical UX design, or simple UI styling without ADHD context.

Self-improving context loader that MUST be run before every prompt. Searches Graphiti for relevant past work, loads appropriate vibe, and provides intelligent recommendations.

Comprehensive guide for Amplitude MCP queries. Use when analyzing product analytics, user behavior, funnels, retention, experiments, or metrics. Reduces context overhead by documenting query patterns, event taxonomies, and RDC-specific configurations. Triggers on Amplitude, product analytics, user behavior, funnel analysis, retention, experiment analysis, or metric queries.

Guides creation of high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK). Covers tool design, authentication, Docker deployment, and evaluation creation. NOT when consuming existing MCP servers (use the server directly).

Validate that skill instructions use domain-agnostic language by mentally applying them across three unrelated contexts and revising vocabulary that carries meaning in one field but creates friction in others. Use when: (1) a skill draft uses terminology from its origin domain, (2) reviewing a skill that works well in some contexts but feels awkward in others, (3) before finalizing any skill intended for general use.

Recognize, diagnose, and mitigate patterns of context degradation in agent systems. Use when context grows large, agent performance degrades unexpectedly, or debugging agent failures.

Validate and sanitize user input to prevent XSS, injection attacks, and ensure data quality. Use this skill when you need to validate forms, sanitize user input, prevent cross-site scripting, use Zod schemas, or handle any user-generated content. Triggers include "input validation", "validate input", "XSS", "cross-site scripting", "sanitize", "Zod", "injection prevention", "validateRequest", "safeTextSchema", "user input security".

Military-style SITuation REPort protocol for multi-agent coordination. Enforces structured status reporting with 🟢🟡🔴 codes, quantitative progress (0-100%), blockers, dependencies, ETAs, and authorization codes for secure handoffs. Prevents communication failures, lost context, and delayed blocker reporting. Use when: coordinating multiple agents, wave execution, reporting progress, requesting status updates, handing off deliverables.

Creates production-grade, reusable skills that extend Claude's capabilities. This skill should be used when users want to create a new skill, improve an existing skill, or build domain-specific intelligence. Gathers context from codebase, conversation, and authentic sources before creating adaptable skills.

Read and extract content from EPUB ebook files. Use this skill when the user wants to read an EPUB file, extract text from an ebook, view EPUB metadata (title, author), list chapters or table of contents, search within EPUB content, or analyze ebook content.

Build type-safe APIs with Hono - fast, lightweight routing for Cloudflare Workers, Deno, Bun, and Node.js. Set up routing patterns, middleware composition, request validation (Zod/Valibot/Typia/ArkType), RPC client/server with full type inference, and error handling with HTTPException.Use when: building APIs with Hono, setting up request validation with schema libraries, creating type-safe RPC client/server communication, implementing custom middleware chains, handling errors with HTTPException, extending context with custom variables, or troubleshooting middleware type inference issues, validation hook confusion, RPC performance problems, or middleware response typing errors.

Intelligent pattern selection for Fabric CLI. Automatically selects the right pattern from 242+ specialized prompts based on your intent - threat modeling, analysis, summarization, content creation, extraction, and more. USE WHEN processing content, analyzing data, creating summaries, threat modeling, or transforming text.

Enhanced Just-In-Time document loading system that intelligently discovers, loads, and caches relevant documentation based on user intent and project context. Use when users need specific documentation, when working with new technologies, when answering domain-specific questions, or when context indicates documentation gaps.

This skill should be used when the user requests "get JSON with fields X, Y, Z", "need JSON output from this text", "create structured JSON from", or provides a JSON schema they want extracted from input data. Use this for converting ANY text into structured JSON format.

Lock tasks to user-provided sources (PDF/txt/URL) by creating a per-task context container, ingesting and chunking only those sources, ranking chunks for relevance, and enforcing negative constraints against out-of-scope content. Use when strict source grounding is required.

Load architecture principles and core conventions for grounding work against project standards - simple context loading for all workflow stages

Stream long-form content to markdown files with resume capability. Writes content incrementally with section markers, enabling recovery if context limits are hit. Use when generating long documents (over 1000 lines), B-SPEC or specification writing, multi-section reports, any task where context compaction may occur mid-generation, or when user explicitly requests streaming output. Commands: init, write, status, resume, finalize, repair.

Expert guidance for tRPC (TypeScript Remote Procedure Call) including router setup, procedures, middleware, context, client configuration, and Next.js integration. Use this when building type-safe APIs, integrating tRPC with Next.js, or implementing client-server communication with full TypeScript inference.
