What problem does it solve? Before any wecomcli-* business skill runs a wecom-cli command, the CLI must be installed at version 1.2.1 or higher and the WeCom credentials must be authorized; this Skill performs those shared prerequisite checks so business commands do not fail unpredictably. ## Core Features & Use Cases - CLI Installation and Version Check: Runs wecom-cli --version and requires version 1.2.1 or higher, directing users to the Pinvou plugin center instead of manual npm installs when missing or outdated. - Authorization Flow: Checks auth status with wecom-cli auth show --status and initializes credentials via wecom-cli auth init --noninteractive with QR-code scanning when unauthorized. - Identity Retrieval and Output Constraints: Fetches bot or authorized user identity via wecom-cli identity whoami and enforces a global rule that internal IDs (userid, mail_id, docid, etc.) must never appear in user-facing replies. - Use Case: Before sending a WeCom message or querying a document, run this check to confirm the CLI is ready and authorized, then proceed to the corresponding business skill. ## Quick Start Before running any wecom-cli command, verify the CLI is installed at version 1.2.1 or higher and that WeCom authorization shows as authorized.
