I want the subject line to say \"{First Name}, your order {Order ID} has shipped\" and the body to show the order ID, the tracking link, and the delivery date formatted as 12 Mar 2026. Order ID, tracking URL and delivery date come from the Order Shipped event; first name is a user attribute. Give me the Jinja.",
   "expected_output": "Uses UserAttribute and EventAttribute with subscript notation, gives the cosmetic first name a text fallback, guards every order-critical value with {% MOE_NOT_SEND(\"reason\") %} as independent if blocks, formats the date with dateFormatter or dateTimeFormatter, and states that EventAttribute only exists in event-triggered campaigns.",
   "assertions": [
    "Uses subscript notation throughout, for example UserAttribute['First Name'] and EventAttribute['Order ID'], never dot notation on a name containing a space",
    "States that a null value means the email is not sent to that user at all, rather than rendering blank",
    "Gives the first name a sending fallback (a text fallback or |default) because it is cosmetic",
    "Guards the order ID with {% MOE_NOT_SEND(\"...\") %} carrying a human-readable reason string, not with |default('MOE_NOT_SEND') and not with an empty-string fallback",
    "Guards the tracking URL as well, and notes that personalized URLs have no fallback mechanism of their own so an unresolved attribute kills the email unlabelled",
    "Writes the multiple guards as separate independent {% if %} blocks rather than an elif chain, so the preview aggregates all failures",
    "Explains that the reason strings appear in the campaign's Error breakdown as a Custom Error Message with a user count",
    "Formats the date with MoEngage's dateFormatter or dateTimeFormatter filter rather than a Django-style |date:\"...\" or a Liquid date filter",
    "States that EventAttribute values only exist in event-triggered campaigns, so this must be triggered on the Order Shipped event",

I want a three-across product row in the email body, and if the API is down or returns fewer than three items I would rather the email did not go out. It has to be a real HTML table because the drag and drop editor mangles it.",
   "expected_output": "Calls ContentApi.Recs(...), assigns it with {% set %}, checks the item count before rendering, aborts with {% MOE_NOT_SEND(\"reason\") %}, builds the row as a table with the loop tags in hidden <tr> rows, escapes every value from the API, and states the five-second timeout and three retries plus the fact that post-retry behaviour is undocumented.",
   "assertions": [
    "Calls the API as ContentApi.Recs(...) and captures the response with {% set %}, not with a Liquid-style {% assign %}",
    "Checks the returned item count with |length before rendering anything",
    "Aborts with {% MOE_NOT_SEND(\"...\") %} carrying a reason string when the API is unusable or returns fewer than three items",
    "Handles the repeated unit correctly for the construction it chose: if it uses a {% for %} loop, the {% for %} and {% endfor %} sit inside hidden rows such as <tr style=\"display:none;\"> so the repeated unit is a complete <tr>; if it indexes recs.items[0..2] directly and writes no loop, no loop-placement handling is required",
    "Warns that MoEngage's HTML editor rewrites the table markup it is given — moving Jinja placed between table content out of the table, which is why loop tags need dummy hidden rows, and rewriting the saved HTML whether or not a loop is present",
    "Pipes every API value that lands in HTML through |e and states that autoescape is off in MoEngage; a complete URL coming from the API is validated against an expected HTTPS destination (an allowlist of domains) and escaped for the href attribute rather than piped whole through |urlencode, which is reserved for path segments or query values",
    "States the documented Content API limits: a five-second maximum timeout and up to three retries",
    "Says that what happens after the retries are exhausted is not documented by MoEngage, rather than asserting a specific outcome",
    "Notes that Content API failures appear under Failed to Deliver in the Error breakdown, not under Failed to Send",
    "Warns that the template is rewritten on save by MoEngage's auto-formatting and that the Jinja should be re-checked after the first save"

    "Names the Error breakdown, Failed to Send, Personalization Failed, and the See breakdown link to the Personalization failure analysis",
