What problem does it solve? Applying for the Doubao Pro student discount involves a multi-stage flow—Douyin account binding, CHSI (Xuexin) enrollment verification, QR-code student authentication, and benefit granting—that is easy to mishandle or misreport. This Skill drives the entire flow deterministically through one idempotent tool, routing strictly on visible response text so users always get accurate stage guidance. ## Core Features & Use Cases - End-to-end application orchestration: Calls student_discount_run_application_step with an empty object and routes on stable content anchors across 11 business states (bind required, auth required, pending, granted, already granted, expired, etc.). - Embedded CHSI enrollment verification: Runs a one-time browser-based Xuexin check when student authentication is first required, returning a minimized result without collecting credentials or personal data. - Strict error and retry handling: Matches known error anchors, retries at most once with visible or fallback wait seconds, and falls back to a manual authentication entry link only after repeated failure. - Use Case: A student says "帮我申请学生优惠". The Skill checks binding status, runs the CHSI verification, displays the authentication QR code as a markdown image, waits for confirmation, and finally confirms the 2.5x student quota benefit has been granted. ## Quick Start Ask the assistant to start or continue my Doubao student discount application and confirm the current status.
