AI & Architecture Skills

anthropic-architect

Determine the best Anthropic architecture for your project. Analyze requirements and receive tailored recommendations on the optimal architecture using Skills, Agents, Subagents, Prompts, and SDK primitives based on proven decision rubrics and 2025 best practices.

Key features:

• Analyze project requirements and complexity
• Recommend optimal architecture (Skills vs Agents vs Prompts vs SDK)
• Apply comprehensive decision rubrics
• Progressive disclosure design guidance
• Security and performance best practices
• Real-world architectural patterns
• Cost optimization strategies

Usage:

• "Using anthropic-architect, determine the best architecture for my code review system"
• "Help me choose between Skills and Agents for this workflow"
• "Analyze my project and recommend the right Anthropic primitives"
• "What's the best architecture for automated testing?"

The Four Anthropic Primitives:

• Skills - Reusable domain expertise with progressive disclosure
• Agents/Subagents - Autonomous task handlers with isolated contexts
• Direct Prompts - Simple, clear instructions for straightforward tasks
• SDK Primitives - Custom workflows and system integrations

Decision Framework:

Task Complexity:
  Low (1-3) → Direct Prompts
  Medium (4-6) → Skills
  High (7-9) → Agents/Subagents
  Custom (10) → SDK Primitives

Plus evaluation of:
- Reusability requirements
- Context management needs
- Security & control requirements
- Performance needs
- Maintenance burden
- Time to market
