## Tools (as reported by the server, not verified)

- `get\_human\_state`: Get current unified human state for a session. Call this before generating important responses. Returns: - state: calm \| relaxed \| focused \| stressed \| acute\_stress - stress\_score: 0-100 \(lower = calmer\) - confidence: 0.0-1.0 \(based on signal quality and device type\) - suggested\_action: maintain\_eng
- `ingest`: Send biometric signals from any sensor, get unified state back. Required: session\_id + timestamp \(ISO 8601\) + at least one signal. Send whatever you have — the API fuses all signals into one state. Common signals \(highest impact\): - heart\_rate \(bpm, 30-220\) + rmssd \(ms\) — cardiovascular - tone: calm
- `get\_trigger\_memory`: Retrieve psychological trigger profile for a subject. Returns which conversation topics consistently cause stress \(active triggers\) and which have been resolved over time. - active triggers: topics where stress was elevated across multiple sessions. Tread carefully. - resolved triggers: topics where
- `get\_session\_history`: Get state history for a session over time. Returns timestamped datapoints with stress\_score, state, and heart\_rate for each observation. Includes an overall trend: rising \| falling \| stable. Use minutes parameter to control the lookback window \(default: 5, max: 60\). Useful for detecting stress patte
- `delete\_subject`: Permanently delete all sessions and trigger memory for a subject. Irreversible. Only call when the user explicitly requests this deletion.
- `request\_api\_key`: Start free API key authorization; no existing API key needed. Returns a verification\_url. Ask the user to open that URL in their browser, enter their own email, then open the verification email and confirm access for their agent. This tool does not accept email addresses and does not send email. Do
- `check\_api\_key\_status`: Check a pending API key authorization using its request\_id. Use request\_id exactly as returned by request\_api\_key, never an email. Poll every 10 seconds. awaiting\_user means the user must open the URL; pending means email verification is still required. ready returns the API key once only. Store it
