Service	Tools
Apps	`apps_build` · `apps_create` · `apps_edit` · `apps_fork` · `apps_embed` · `apps_read` · `apps_search` · `apps_test` — build small web tools and put them anywhere
Archive	`archive_search` · `archive_list` — everything this instance has collected, across news, video, markets and posts at once. Use it when the question crosses a service, or when you do not know which one would hold the answer
Blog	`blog_create` · `blog_read` · `blog_list` · `blog_update` · `blog_delete` — publish, with AI-generated daily digests
Browser	`browser_read` · `browser_shot` — a real browser for the pages a plain fetch cannot read: open one and get its text after its JavaScript has run, or photograph it and get a URL for the picture. Costs, because it runs a Chromium; a plain fetch is free and is the right first try
Chat	`chat_rooms` · `chat_messages` · `chat_send` — the live discussion rooms attached to an item, and saying something in one
Contacts	`contacts_add` · `contacts_find` · `contacts_list` · `contacts_delete` — turn a name into an address
Docs	`docs_write` · `docs_read` · `docs_list` · `docs_delete` — your own documents: a title and a markdown body, private by default. `docs_write` with an `id` replaces one. For something short to remember, use notes; apps persist through `mu.db`, which is a record store rather than documents
Events	`events_create` · `events_list` · `events_delete` · `events_free` — schedule, cancel, and find when you are free, counting the Google Calendar you already keep
Files	`files_put` · `files_get` · `files_list` · `files_share` · `files_delete` — keep a file, get a URL
Flights	`flights_overhead` · `flights_track` · `flights_airport` — where aircraft are, live from the positions they broadcast themselves. No schedule behind it, so it says where an aeroplane is and never why it is late
Food	`food_product` · `food_search` · `food_hygiene` — what is in a packet and whether the kitchen is clean. A barcode gives ingredients, allergens, nutrition per 100g and how processed it is, from Open Food Facts; `food_hygiene` gives the Food Standards Agency's inspection rating for any UK business. Where the data is silent it says so, because an absence of allergen information is not an absence of allergens. Needs no key
Hazards	`hazards_quakes` · `hazards_alerts` · `hazards_floods` — recent earthquakes worldwide from the USGS, with magnitude, place, how long ago and any tsunami warning, and current disasters from GDACS: cyclones, floods, volcanoes and wildfires, green through red. And flood warnings in force in England from the Environment Agency — the one hazard here that is a forecast rather than a record, since a warning says flooding is expected.
