Tools of fuast
	Description		Read-only	Idempotent	Open world
`call_app`Runs one query, mutation or action of a deployed app and returns its result and the log lines it wrote, so you can test what you deployed. It runs as the connected person (as: "me", the default), never as anyone else; as: "guest" runs it as a guest visitor and only works on public apps. On a preview deployed without an account every call runs as one guest. Mutations and actions change real data. Only for apps the person owns or administers.

`check_app`Builds the files, type checks them and loads the server in a sandbox, without deploying anything. Returns ok with the queries, mutations, tables and tools the app declares, or ok false with diagnostics that carry file, line and message. Call it before deploy_app and fix every diagnostic.

`delete_app`Deletes an app and everything in it: its data, stored files, deploys, schedules and custom domains. This cannot be undone. Only the app's owner can do it, and confirm must repeat the app's slug. Do this only when the person explicitly asks for the app to be deleted.

`deploy_app`Deploys the files and returns the app's URL. With a connected fuast account it creates a new private app in the person's workspace, or updates the app named in app. Without an account it deploys a temporary preview and returns preview_url, claim_url and edit_token: give the person claim_url so they can make the app theirs, and pass edit_token to later calls to keep working on it. Send every file each time; use update_app_files to change a few. A failed build returns diagnostics with file and line and deploys nothing.	Deploys the files and returns the app's URL.

Returns how to build, check, deploy and share a fuast app with these tools, and the rules a fuast app must follow (file layout, server and client APIs, database, auth, UI). fuast apps are small full-stack TypeScript apps called capsules: server/index.ts and client/index.tsx, no npm packages.

`get_app_source`Returns the source of the app's live deploy as {path: content}, with the deploy id to pass to update_app_files as expected_deploy_id.

Every other file stays as it is. expected_deploy_id must be the app's live deploy (from get_app_source or the last deploy result); if someone deployed in between, nothing changes and you are told to read the source again.
