## Tools
- contextual_advice - 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.
    has_indoor_sources: Indoor pollution sources (smoking, woodstove).
    audience: Target audience — general, children, elderly, respiratory, pregnant.

- exposure_assessment - Estimate personal daily air pollution exposure across home, work, and commute.

Uses time-weighted modelling across environments: home (with indoor source
adjustments), work, and commute (with route-based pollution and transport mode
factors). Based on annual average pollution estimates, not live readings.

Args:
    home_postcode: Home location UK postcode (e.g. "SE17 1RL"). Required.
    work_postcode: Work/school location postcode. Omit if not commuting.
    transport_mode: Commute mode — walk, cycle, bus, car, train, tube.
    work_frequency: How often you commute — most_days, some_days, less_often, never.
    commute_hour: Hour of commute (0-23) for time-of-day pollution adjustment.
    cooker_type: Home cooker type — gas, electric, induction, unknown.
    smoking_at_home: Whether anyone smokes indoors (major PM2.5 source).
    tube_line: London Underground line for tube commuters (e.g. "victoria").
