alibabacloud-cdn-refresh-preload
Read-only diagnostics for Alibaba Cloud CDN refresh and preload issues. Use when a URL/file/directory refresh or preload looks ineffective - refresh failed, preload failed, cache not cleared, or the task failed. Verifies task records and edge cache status, and produces a diagnosis report; never submits refresh/preload jobs. Triggers: "refresh failed", "preload failed", "cache not cleared", "purge not working", "prefetch not cached", "warm up ineffective", "invalidation unsuccessful", "pre-warming failure", "pre-fetching".

What this skill does
CDN Refresh and Preload Diagnostics Diagnose CDN refresh and preload issues: "content not updated after refresh", "preload failed", "cache not cleared", "URL refresh not effective", "directory refresh still shows old content". Core approach: First query refresh/preload task records to confirm task status, then follow different diagnostic branches based on refresh type (file / directory / preload). Observability All OpenAPI calls (invoked through the aliyun CLI) include: User-Agent: --user-agent AlibabaCloud-Agent-Skills/{SKILLNAME}/{session-id} SKILLNAME: alibabacloud-cdn-refresh-preload session-id: 32-character hex string generated per diagnostic session Prerequisites 1. Python 3.11+ and aliyun CLI — required: aliyun cdn describe-refresh-tasks and aliyun sts assume-role are both invoked via the aliyun CLI (no direct HTTP signing). No external Python SDK dependencies. 2. Alibaba Cloud credentials — Credentials are resolved automatically by the aliyun CLI default credential chain (environment or ~/.aliyun/config.json). Do not read, print, or pass AK/SK/STS tokens explicitly. 3. Target inputs: URL (the resource to diagnose) and UID (the Alibaba Cloud account UID). UID can be omitted — it defaults to the caller account derived via aliyun sts get-caller-identity. Auto-fill first, ask second: never ask the user for UID or role name when they can be derived. Auto-fill declaration requirement: Whenever any parameter is auto-filled (UID, domain, URL, or role name), the Agent MUST explicitly declare this in the response or report metadata. For example: "UID auto-derived via sts:GetCallerIdentity: 1772241626973633" or "Domain auto-discovered via DescribeUserDomains: tofirae.com" or "URL auto-extracted from refresh task records: https://tofirae.com/1.png". This declaration is mandatory and must appear in the final output. …
