Detect Humans — external vision skill

AgenticROS skill that wraps an on-robot detection topic as the detect_humans capability. AgenticROS does not run YOLO for you — bring up your perception node, then install this skill.

npx agenticros skills install chrismatthieu/detect-humans
# or pin in config:
# "skillRefs": ["chrismatthieu/detect-humans"]

Restart the gateway / MCP server. ros2_list_capabilities should include detect_humans.

Mission example

{
  "mission": {
    "name": "sample detections",
    "steps": [
      {
        "id": "det",
        "capability": "detect_humans",
        "inputs": { "mode": "subscribe", "timeout_ms": 5000 }
      }
    ]
  }
}

Override the topic if your stack does not publish detections:

{ "capability": "detect_humans", "inputs": { "topic": "yolo/detections", "mode": "subscribe" } }

Requirements

• A ROS 2 node publishing vision_msgs/msg/Detection2DArray (or a transport-compatible equivalent)
• Transport with subscribe support (Zenoh, rosbridge, local, WebRTC)
