Full skill instructions
Service/transactional email extension for Caffeine AI.
This skill adds support for sending service and transactional emails from the backend canister. Use sendServiceEmail for order confirmations, notifications, and similar one-off emails.
This component is for sending service/transactional emails.
There is the prefabricated module mo:caffeineai-email/emailClient.mo which cannot be modified.
module {
public type SendResult = {
#ok;
#err : Text;
};
public func sendServiceEmail(
fromUsername : Text,
recipients : [Text],
subject : Text,
htmlBody : Text,
) : async SendResult;
};
Usage for sendServiceEmail:
import Runtime "mo:core/Runtime";
import EmailClient "mo:caffeineai-email/emailClient";
actor {
public func sendOrderConfirmationEmail(recipientEmailAddress : Text, username : Text, orderReference : Text) : async () {
let result = await EmailClient.sendServiceEmail(
"no-reply",
[recipientEmailAddress],
"Order " # orderReference # " confirmed",
"Hello " # username # ",\nYour order " # orderReference # " has been confirmed. Your items will ship tomorrow.",
);
switch (result) {
case (#ok) {};
case (#err(error)) {
Runtime.trap("Failed to send order confirmation email: " # error);
};
};
};
};
Send personalised marketing emails to subscribers with an unsubscribe link.
Support for sending an email with a link the recipient can click to prove they own the email address.
General file/object storage, such as for images, videos, files, documents and other bulk data. Perfect fit for image galleries, video galleries, and other file or object management. Supports large files beyond IC limit, with browser-cached HTTP URL access.
Authorization system with role-based access control. Must-have for all apps that manage personal or access-restricted data.
HTTP outcalls performed by the backend canister (not in the frontend).
Core infrastructure providing backend connection configuration, storage client, and React app entry point.
Requests invite-link / RSVP based access where guests can submit responses without login while admin can view responses with login.
Approval-based user management.
Send an email with multiple to, cc and bcc addresses.
MANDATORY recipe for every Caffeine build that calls OpenAI (ChatGPT, GPT-4o, an LLM, a chatbot, embeddings). The ONLY supported path is the `openai-client` mops package with a canister-side API-key bearer. Hand-rolling `ic.http_request` to `api.openai.com/v1/...` is a FORBIDDEN anti-pattern — it leaks the bearer across replicated outcalls (security + 13× billing impact), bypasses the typed request/response bindings, and forces hand-rolled JSON on a language with poor JSON support. Load this skill whenever the user, spec, or any prior task mentions ChatGPT, GPT (any version), OpenAI, an LLM, a chatbot, or embeddings — and BEFORE writing any code that touches `api.openai.com`.
MANDATORY recipe for every Caffeine build that posts to X (Twitter). The ONLY supported path is the `x-client` mops package with OAuth 2.0 PKCE. Hand-rolling `ic.http_request` or `icBooking.http_request` calls to `api.x.com/2/tweets`, `api.x.com/2/oauth2/token`, or any other X endpoint is a FORBIDDEN anti-pattern — it bypasses bearer auth, replication-cost safeguards, and `x-client`'s null-field handling. Load this skill whenever the user, spec, or any prior task mentions tweeting, live-tweeting, posting-to-X, posting-a-status, sharing-to-Twitter, or any equivalent phrasing — and BEFORE writing any code that touches `api.x.com`.
Make a canister's data queryable by the Caffeine Data Intelligence agent. Use whenever an app stores structured data (Maps/Lists/arrays of records) that should be answerable in natural language — "top customers", "revenue by region", "active projects". Adds a discoverable `schema()` and a JSON `execute()` query endpoint via the `caffeineai-oql` mops package's `Expose` mixin.
