Agency Agents

About Agency Agents
Agency Agents is an open-source AI framework that replaces generic assistants with hundreds of role-specific agent personas. Each agent has a defined identity, mission, rules, and success metrics, enabling domain-expert performance across engineering, marketing, product, and other fields. By constraining AI to specialized roles, the system reduces hallucinations and improves output consistency for complex tasks like software architecture, product strategy, or marketing execution. Users can activate multiple agents simultaneously to simulate real-world team collaboration, integrating with tools such as Claude Code, Cursor, Copilot, and Aider. The framework supports customization, allowing developers to modify existing agents or create new ones using markdown-based definitions. This approach is designed for developers, startups, agencies, and AI builders seeking scalable, production-ready AI workflows with structured reasoning and higher reliability than single-agent systems.
