Core Concepts

Skills: Domain knowledge and expertise (e.g., coding standards, design patterns) Commands: Quick shortcuts with /command syntax Agents: Autonomous task executors with tool access Workflows: Multi-step processes orchestrating the above

Note: Claude Code has built-in support for Skills, Commands, and Agents. Workflows can be implemented through these components.

Getting Started

Installation

1. Clone this repository:

git clone https://github.com/oyjs1989/marketplace.git
cd marketplace

2. Browse the available components in each directory

3. Copy the desired components to your Claude Code project

Usage

Each component type has its own usage pattern:

• Skills: Invoke using skill notation in your Claude Code sessions
• Commands: Use with slash notation (e.g., /command-name)
• Agents: Configure as specialized assistants for specific tasks
• Workflows: Follow the documented process for complex operations

Available Components

Skills

Problem-Solving Framework (v1.0.0)

Comprehensive problem-solving capabilities with cognitive agents and specialized analysis modules.

Core Orchestrator:

• problem-solving - Main orchestrator with 5 cognitive agents:
  • 🔵 systems-thinking - Global perspective, emergent properties, leverage points
  • 🟢 modeling-abstraction - Conceptual models, DDD patterns, abstraction layers
  • 🟣 decomposition - Hierarchical breakdown, WBS, composition strategies
  • 🟠 iteration - Incremental improvement, feedback loops, MVP approach
  • 🔷 pattern-recognition - Pattern discovery/refactoring, GoF patterns

Analysis Modules:

• decision-support - Multi-criteria decision analysis (MCDA, AHP, TOPSIS, weighted scoring)
• risk-assessment - Risk evaluation using COSO ERM and ISO 31000 frameworks
• cost-benefit-analysis - Economic evaluation (ROI, NPV, IRR, TCO, payback period)

Methodology Skills:

• methodology-agile - Scrum framework (Sprint planning, user stories, velocity, burndown charts)
• methodology-devops - CI/CD pipelines, IaC, monitoring, incident response, DORA metrics
• methodology-waterfall - Traditional SDLC (6 stages, SRS, SDD, gate reviews, change management)

Quick Start Examples:

# Comprehensive problem analysis
"Help me analyze this microservices architecture design"
→ Triggers all 5 cognitive agents in parallel

# Decision support
"Compare MongoDB vs PostgreSQL for my use case"
→ Uses MCDA with weighted criteria matrix

# Risk assessment
"Evaluate risks of cloud migration"
→ Generates risk matrix with mitigation strategies

# Cost-benefit analysis
"Should we build or buy a CRM system?"
→ Calculates ROI, payback period, NPV

# Agile planning
"Plan the next Sprint for user authentication"
→ Provides Scrum guidance and templates

# DevOps design
"Design a CI/CD pipeline for Node.js microservices"
→ Provides stage-by-stage pipeline configuration

# Waterfall project
"Create requirements specification for banking system"
→ Generates IEEE 830 SRS template

Integration Patterns:

• Problem-solving → Risk assessment → Decision support (comprehensive analysis)
• Agile + DevOps (modern software development)
• Waterfall + Cost-benefit analysis (traditional projects)

Output Language: All skills output in Chinese (中文) following FUTU standards.
