Universal Agent Architecture v3.0.0 Major architectural change implementing Anthropic's recommendation: "Don't Build Agents, Build Skills Instead" Changes: - 88 agent classes → 1 UniversalAgent - Dynamic skill loading (106 skills) - Parallel execution preserved via WorkerPool - Circuit breaker for Human-in-the-Loop safety - Checkpoint/resume for recovery - 9 core skills created - 30-50% token reduction expected New API endpoints: - POST /agents/universal/invoke - POST /agents/oneshot/invoke Breaking: Old agent classes still work but Universal Agent is now preferred.
