Personalised air quality advice for a UK location and a specific
user context.
Use this tool whenever the user asks an air-quality question that
depends on *who they are* or *what they're about to do*: e.g. asthma,
pregnancy, school-age child, gas cooker at home, tube commute,
outdoor exercise. It composes location-specific pollution with the
user's personal context to produce evidence-based advice — far more
targeted than a generic "high pollution day" handout.
Composable with Hermes: pass pm25/no2 from Hermes get_current_aq for
advice based on live readings rather than annual average estimates.
Returns structured advice with a plain-English summary, health context,
and local intervention information. Present the 'summary' to users first.
Args:
postcode: UK postcode (e.g. "SE17 1RL"). Provides coords + LAEI pollution.
latitude: Latitude for coordinate-based lookup.
longitude: Longitude for coordinate-based lookup.
pm25: PM2.5 concentration in ug/m3. Overrides location-based estimate.
no2: NO2 concentration in ug/m3. Overrides location-based estimate.
setting: Context — residential, school, workplace, outdoor_exercise, commute.
has_gas_cooker: Whether the person has a gas cooker (affects indoor advice).
commute_mode: If setting is commute — walk, cycle, bus, car, train, tube.
