list_cities | The cities CitySignal covers, with their slug, timezone, center point, the official sources it reads, and status: live, or preview (still being checked, open to sign-ups, trackers not yet public). Call this when unsure which city slug to pass. |
city_now | Live alerts in a city, deduplicated from official feeds (roads, transit, weather, power, water, construction) and placed by the app's own rule into four buckets: now (live and current), ongoing (live for more than two days, or unconfirmed), ahead (starts later, within 7 days, grouped by day) and rec |
city_near | Alerts within a radius of a latitude and longitude in a city, nearest first, each with its distance in miles: live ones (bucket now, ongoing or ahead) and ones that ended in the last 12 hours (bucket recap, so 'was there anything here this afternoon' can be answered). Default radius 3 miles, max 25. |
city_week | Week-over-week memory for a city: counts by category for the last 7 days and the 7 before, a plain-language read of the week, measured insights, where it concentrated (areas and corridors), why an unusual week was unusual, and what a newsroom published about it. Use for 'how has this week been', 'is |
city_incidents | Four weeks of what happened in a city, sorted by kind, for one category. roads (default): crashes, stalled vehicles, hazards and debris, closures, vehicle fires. power: outages by size (one home, small, neighborhood, large), planned outages, downed or sparking lines. transit: delays, canceled trips, |
cities_report | Report mode: how every live CitySignal city is doing, in one call. The CitySignal Index for the last complete week (Sunday to Saturday): each city scored against its own typical week (Quiet, Typical, Busy, Heavy, with how many times typical), per category (roads, water, power, construction, transit) |
city_events | Events, concerts and home games coming up in a city within the next N days (default 7, max 14), with venue area, ticket price range and a ticket link when listed, and expected local traffic impact when known. Each event carries placeholder_url, a CitySignal summary card (not a picture) you may link |
get_signal | Full detail for one signal by its signal_id (from any other tool): summary, place, area, corridor, timing, source link, confidence and whether a live camera check confirmed or contradicted it. When a real picture exists it carries picture_url, label and link (a ready markdown link), and the card com |
city_cameras | Road cameras within a radius of a latitude and longitude (default 1 mile, max 5), nearest first, each with a link to its current still and whether it has live video; plus the camera checks CitySignal ran on alerts there in the last N hours (default 24, max 72): what the camera showed and whether it |
city_pictures | Up to six CitySignal picture cards for incidents in a city, including ones that already cleared: the frame a camera check kept, or a live view while the incident is still going. Each card has a headline, time, city, and a Cleared / Earlier today tag when it's over. Incidents with no picture are left |
get_profile | The connected CitySignal account: a stable opaque id and display name. Call this to confirm which account is linked before reading personal tools. |
my_day | The connected person's own Now / Ongoing / Ahead / Recap: live signals that touch their saved spots and routes, in the same buckets the app shows, plus today's calendar line. Use for 'anything I should know today', 'what's near my places', 'is my area affected'. Needs a connected account. |
my_brief | Today's written brief for the connected person: top alerts, citywide items, what is near their spots with why it matters and a recommended action, events, what is ongoing, what came and went since the last brief. Use when they ask for their briefing or a summary of their day. Needs a connected accou |
my_routes_now | Each of the connected person's saved routes with its current state (Clear, Minor delay, Expect delays, Consider another route) and what changes how the road drives on its corridor now and ahead: crashes, lane closures, roadwork, weather over the route's counties, and event crowds around the trip tim |
my_along_the_way | Errands on the connected person's list that fit a trip they already make today, with the store, the detour in minutes, why that store, and a price line when one is known. Use for 'what can I pick up on the way', 'any errands I can do today'. Needs a connected account. |
my_list | The connected person's shopping list as Scout priced it at their home Kroger: each item with product, size, price and whether it is on sale, plus the running total.

add_errand | Adds one errand to the connected person's own list, in their words ('milk and eggs', 'pick up lotion at the pharmacy'), the way the app, Siri and a text to Scout do: Scout reads the store kind from the words and fits the errand into a drive they already make.

get_detour | Resolves a DETOUR-XXX code for the connected person: which drive it is on, the event, whether it is worth it (a stop) or dodge it (a way around), the streak and offer lines, and the link that opens it. Codes are per person and per day; a code that has passed says so. Use when the person says or past |
