scenarios covering all validation rules: Valid Scenarios (20): - LLM actors (minimal, with prompt, tools, memory, context) - TOOL actors (minimal, inline definitions) - GRAPH actors (linear, conditional, subgraphs) - All example YAML files (simple_llm, llm_with_tools, etc.) - Context views (strategist, executor, reviewer, full) - Memory configurations - Environment variables Invalid Name Scenarios (4): - Missing namespace - Multiple slashes - Empty namespace - Empty name Invalid LLM/TOOL/GRAPH Scenarios (7): - LLM without model - TOOL without tools - TOOL with empty tools list - GRAPH without model - GRAPH without route Graph Topology Validation (6): - Duplicate node IDs - Invalid entry node - Invalid exit nodes - Invalid edge references (from_node, to_node) - Cyclic graphs Tool/Node Validation (3): - Inline tool without namespace - Invalid parameter names - Invalid node ID formats Additional Scenarios (10): - YAML I/O (save/reload, missing files) - Edge priorities -
