What problem does it solve? Requesting official bill files from payment platforms like WeChat Pay and Alipay involves many in-app steps, identity verification handoffs, and waiting periods, which makes manual or ad-hoc automation error-prone. This Skill provides a unified entry point that routes each request to the correct channel workflow and device-control backend, tracks state per channel, and pauses safely for user authentication. ## Core Features & Use Cases - Channel Routing: Identifies the bill source (WeChat Pay, Alipay, or multiple channels at once) and loads the matching channel workflow file with its own parameter mapping for time range, transaction type, and delivery method. - Backend Separation: Keeps channel business flows independent from device-control backends such as Computer Use with macOS iPhone Mirroring, so new backends can be added without rewriting channel logic. - State Machine with Auth Handoff: Follows a shared state contract (submitted, generating, downloadable, saved, transferred) and immediately pauses at identity verification pages, never reading or entering passwords, Face ID, or device credentials. - Use Case: Ask to export the last three months of Alipay and WeChat Pay statements; the Skill applies for each transaction record, waits for generation, downloads the files to local device storage, and reports per-channel results without exposing bill contents. ## Quick Start Use the bill-export skill to export my WeChat Pay and Alipay statements for the last three months and save them to my device's local files.
