aiagentskit/claude-agents-library

Provides 34 production-ready agent configurations across 7 professional categories (engineering, product, marketing, design, etc.), each with detailed prompts, responsibilities, and task-specific expertise. Integrates with Model Context Protocol (MCP) patterns and includes a cost optimization matrix recommending specific Claude models for different tasks, offering documented savings up to 82% on API costs. Architecture emphasizes role-based persona consistency through detailed markdown templates covering communication style, core skills, and example prompts rather than requiring custom prompt engineering.
