MANDATORY 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.httprequest 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.
