Nefesh Human State Agent

Provides real-time human physiological state awareness for AI agents. Fuses biometric signals (heart rate, HRV, voice, facial expression, text sentiment) into a unified stress score (0-100) with behavioral adaptation prompts. Includes trigger memory for cross-session psychological context and adaptation effectiveness feedback.

Skills (4)

  • Get Human State get-human-state
    Returns current stress state (0-100), suggested_action (maintain/simplify/de-escalate/pause), and adaptation_effectiveness showing whether your previous action reduced stress.
  • Ingest Biometric Signals ingest-signals
    Send biometric signals (heart rate, HRV, voice tone, expression, sentiment, 30+ fields) and receive unified state. Include subject_id for cross-session trigger memory.
  • Get Trigger Memory get-trigger-memory
    Retrieve psychological trigger profile - which conversation topics cause stress (active) and which have been resolved over time.
  • Get Session History get-session-history
    Timestamped state history with trend (rising/falling/stable). Useful for detecting stress patterns during conversations.
