About this skill

Problem Solved

When downloading WeChat Channels links, a naive approach often relies on browser cookies, request headers, or the user's normal profile. This skill keeps authentication inside a Skill-only Edge or Chrome profile, accepts https://weixin.qq.com/sph/ links, and downloads using a locally installed browser.

How It Works

Environment check: doctor verifies Python 3.10+, the selected browser, and the dedicated profile; it can install Playwright locally without downloading another Chromium build.
Login session: login opens a visible dedicated browser window for Yuanbao login; closing the window does not sign out, and the local profile is reused.
Resolve and download: resolve verifies metadata and media availability; download streams MP4, defaulting to H.264 and supporting --codec h265 when requested.
Session recovery: on HTTP 401 or SESSION_EXPIRED, the command clears stale session data only in the selected Skill profile, waits for re-login, then retries the original link once.

Boundaries

It only downloads content the user is authorized to access and does not bypass private, deleted, paywalled, or access-controlled material. The browser stays visible by default; use --headless only after a successful headed download on the same browser and machine. Reports include file path, size, title, author, browser, and SHA-256, not media URLs, cookies, generalToken, or request headers.

Use Cases

Save an accessible WeChat Channels MP4 to Downloads after receiving a sph link, then verify title, size, and SHA-256.
Re-scan Yuanbao in the visible browser when the session expires, then let the command retry the same video link.
Check whether a link resolves and media is available with resolve before writing any file.
Prefer Chrome over Edge by saving the browser choice in doctor before running login and download.

Best For

Operations staff assembling channel clips: save accessible shared links to local MP4 and verify metadata.
Product managers archiving content: record resolved title, byte size, and SHA-256 in an archive sheet.
Automation engineers using local browser scripts: keep login and downloads in a dedicated profile instead of the normal browser profile.
Technical testers validating media flows: exercise resolve, download, and session-recovery paths.
