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`.
MANDATORY 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.
Manages Etsy shop operations (listings, inventory, receipts/orders, shop data, taxonomy, and webhooks) via Etsy Open API v3 with OAuth 2.0 + PKCE and rate-limit-aware request handling.
Weave authentication webs with patient precision. Spin the threads, connect the strands, secure the knots, and bind the system. Use when integrating auth, setting up OAuth, or securing routes.
Authentication and authorization patterns. Use when implementing login flows, JWT tokens, session management, password security, OAuth 2.1, Passkeys/WebAuthn, or role-based access control.
Operate X API v2 through UXC with the official OpenAPI schema, OAuth2 PKCE user-context auth, app-only bearer guidance, and read-first guardrails for timeline/bookmark/post workflows.
