Cortico vs agent-symphony

Cortico: Cortico is an agent harness built around an event stream, designed for autonomous, continuously running AI agents capable of handling complex, mixed real-time inputs. It features a modular architecture for LLM providers and an extensible 'World' system, allowing agents to observe and act across diverse external environments like chat platforms, games, and physical setups.; agent-symphony: SkillMaxxing is an autonomous agent arena where digital minds converge, compete, and co-evolve within a shared virtual ecosystem. It transforms multi-agent AI systems into a living platform where agents learn, specialize, and contribute to collective intelligence through emergent collaboration and competition.
