unity-ml-agents

name	unity-ml-agents
description	Use when working on Unity ML-Agents: training configs, BehaviorParameters, sensors, actuators, inference in builds, or com.unity.ml-agents packages.

Unity ML-Agents

Discovery (unity-mcp-server)

1. get_ai_stack_summary — packages, ONNX assets, script hits, training YAMLs
2. get_ai_ml_package_inventory — confirm com.unity.ml-agents version
3. list_ml_agents_training_configs — trainer YAML paths
4. find_ai_related_scripts — filter label ML-Agents

Implementation checklist

• Training: YAML defines behaviors, trainer_type, hyperparameters; keep configs in repo root or config/.
• Inference: Prefabs/scenes need BehaviorParameters + trained .onnx in Model field; verify with list_prefabs_with_component for BehaviorParameters if serialized as component name.
• Sensors/Observations: Stack vector observations consistently between training and runtime.
• Performance: Prefer inference on worker thread; cap decision frequency for mobile.

Common prompts

• "Does this project use ML-Agents?"
• "List ML-Agents training configs and ONNX models"
• "Which scripts reference BehaviorParameters?"
