Integrations & APIs
Integration agent skills teach AI agents to work with specific external services and APIs: third-party platforms, webhooks, MCP servers, and data syncs. Instead of re-explaining an API every session, install the skill and the agent knows the endpoints and conventions.
-
quodsoler Bundle Ue State TreesUse this skill when working with State Tree, StateTree, UStateTree, state machine, StateTreeTask, StateTreeCondition, StateTreeEvaluator, StateTreeSchema, AI State Tree, Mass StateTree, FStateTreeExecutionContext, or data-driven state logic in Unreal Engine. See references/state-tree-patterns.md for task/condition/evaluator templates and references/state-tree-mass-integration.md for Mass Entity integration.
-
quodsoler Bundle Ue Animation SystemUse this skill when working with Unreal Engine animation: AnimInstance, montage playback, blend space, state machine, anim notify, IK, AnimGraph, skeletal mesh, or linked anim graphs.

caffeinelabs Skill Connector SlackEXPERIMENTAL, UNTESTED recipe for posting messages to a Slack workspace from a Caffeine canister via the `slack-client` mops package (Slack Web API). Use it when the user wants their app to send a message to a Slack channel — "post to Slack", "notify a channel", "send a Slack message", or equivalent. The client is a pre-release 0.1.0 drop (bot `xoxb-` or user `xoxp-` token): its request path is verified against the live Slack API (a real message posts), but the success-response decode is not yet runtime-confirmed, so treat it as a starting point and do NOT present Slack as a fully supported platform feature yet. Hand-rolling `ic.http_request` calls to `slack.com/api` is still the wrong move — prefer the generated client so bearer auth, percent-encoding, and JSON parsing come for free.
-
caffeinelabs Skill Connector TwilioEXPERIMENTAL, NOT YET VERIFIED AGAINST LIVE TWILIO, and it spends real money — every message is billed, and a US-bound production number additionally needs A2P 10DLC registration (fees, weeks of lead time). Say both things to the user before building. That said, if a Caffeine build does send SMS or MMS, or configures Twilio messaging, from a canister, the `twilio-client` mops package (Twilio REST API) with a canister-held HTTP Basic credential is the only supported path. Hand-rolling `ic.http_request` calls to `api.twilio.com` or `messaging.twilio.com` is a FORBIDDEN anti-pattern — it bypasses the typed bindings, the per-operation host routing, the Basic-Auth header construction, and above all the non-replicated outcall default that stops one `send` from becoming ~13 billed messages. Load this skill whenever the user, spec, or any prior task mentions SMS, MMS, "text message", "send a text", phone numbers, Twilio, a Messaging Service, A2P 10DLC, toll-free verification, short codes, or an alphanumeric sender —

caffeinelabs Skill Extension StripePayment support based on Stripe, supporting credit cards and debit cards
-
caffeinelabs Skill Connector GooglemailMANDATORY recipe for every Caffeine build that sends email through the user's own Gmail account. The ONLY supported path is the `googlemail-client` mops package (Gmail REST API) combined with the `google-oauth` mops package (token exchange + refresh + PKCE). Hand-rolling `ic.http_request` calls to `oauth2.googleapis.com` or `gmail.googleapis.com` is a FORBIDDEN anti-pattern — it bypasses bearer auth, replication-cost safeguards, and the `google-oauth` library's percent-encoding and JSON parsing. Load this skill whenever the user, spec, or any prior task mentions sending email, Gmail, "notify via email", "forward results by email", or any equivalent phrasing — and BEFORE writing any code that touches a Google endpoint.
-
caffeinelabs Skill Connector GoogledriveMANDATORY recipe for every Caffeine build that lists, reads, creates, shares, or organizes files and folders on the user's own Google Drive. The ONLY supported path is the `googledrive-client` mops package (Drive REST API v3) combined with the `google-oauth` mops package (OAuth 2.0 token exchange + refresh + PKCE). Hand-rolling `ic.http_request` calls to `oauth2.googleapis.com` or `www.googleapis.com/drive/v3` is a FORBIDDEN anti-pattern — it bypasses bearer auth, the `is_replicated = ?false` replication-cost safeguard, and the `google-oauth` library's token handling. Load this skill ONLY when the user, spec, or a prior task refers to **Google Drive specifically** — e.g. "Google Drive", "my Drive", "Drive files/folders", a Drive file/folder ID or share link, "upload to Google Drive", "list my Drive files", or Drive sharing/permissions. Do NOT load it for generic file storage, documents, uploads, or access-control features that are not Google Drive — those are unrelated and this connector must not be attached
-
caffeinelabs Skill Extension Posting To XMANDATORY 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`.
-
caffeinelabs Skill Connector GooglecalendarMANDATORY recipe for every Caffeine build that lists upcoming events or creates events on the user's own Google Calendar. The ONLY supported path is the `googlecalendar-client` mops package (Calendar REST API v3) combined with the `google-oauth` mops package (token exchange + refresh + PKCE). Hand-rolling `ic.http_request` calls to `oauth2.googleapis.com` or `www.googleapis.com/calendar/v3` is a FORBIDDEN anti-pattern — it bypasses bearer auth, replication-cost safeguards, and the `google-oauth` library's percent-encoding and JSON parsing. Load this skill whenever the user, spec, or any prior task mentions scheduling, calendar events, appointments, meetings, "add to calendar", or any equivalent phrasing — and BEFORE writing any code that touches a Google endpoint.
