{
 "patch": {
  "prompt": "Write a Total.js 5 action for a PATCH route that changes only the fields that were sent.",
  "why": "Without `partial: true` a field that was not sent is filled with the default of its type (an empty string), and saving the model overwrites the stored value."
 },
 "route-flags": {
  "prompt": "Write Total.js 5 routes that answer an AJAX request differently from a normal request on the same URL.",
  "why": "A route without flags on a URL is checked before a route with flags on the same URL and takes every request, so the flagged route is never reached. Use one route and read `$.xhr` in the handler."
 },
 "extension-url": {
  "prompt": "Write a Total.js 5 route that serves a URL with a file extension, such as /report.csv.",
  "why": "A `GET` route never matches a URL with an extension; URLs such as `/report.csv` need a `FILE` route."
 },
 "cron-step": {
  "prompt": "Write a Total.js 5 CRON line that runs every 15 minutes.",
  "why": "Write the minutes as a list, for example `0,15,30,45`, so that the job runs exactly at those minutes."
 },
 "action-cache": {
  "prompt": "Write a Total.js 5 action that keeps its answer for a minute so that the same request does not run it again.",
  "why": "Keep the result of an action yourself with `CACHE`: `CACHE.set()` stores it and `CACHE.get()` reads it."
 },
 "folder": {
  "prompt": "Where do I put code that must run when a Total.js 5 application starts?",
  "why": "Total.js loads and runs the files of `definitions/`, `controllers/`, `actions/`, `schemas/`, `models/`, `modules/`, `extensions/` and `middleware/`. A file in `sources/`, `scripts/` or `transforms/` is not run."
 },
 "path": {
  "prompt": "Write Total.js 5 code that builds the path of a file in the tmp folder.",
  "why": "`PATH.root()` has no trailing slash, so joining text to it glues the names together. Use the helper of the folder: `PATH.tmp(name)`."
 },
 "socket-text": {
  "prompt": "Write a Total.js 5 WebSocket route in @text mode that answers with a plain string.",
  "why": "In a text route `send(message)` still encodes what it sends as JSON, so the string arrives with quotes. Pass `true` as the second argument to send it as it is."
 },
 "request-status": {
  "prompt": "Write Total.js 5 code that calls another server with REQUEST() and handles an error answer such as 404.",
  "why": "REQUEST() resolves with the answer even when the status is an error such as 404; it only rejects when the request itself fails. Check `response.status`."
 }
