Baoyu WeChat Summary skill: what it does and how to install it

What it does. Fetches WeChat messages with the external wx command, resolves groups and senders, and writes normal or optional roast digests with topics, attribution, statistics and profiles. It maintains incremental history, per-user profiles and group fact memory across runs, while supporting saved preferences and bot-directed questions.

When to use it. For summarising a WeChat group over a date range or since the previous digest, including profile backfills. It requires wx-cli and does not install it automatically or decode images without supplied descriptions; bot answers do not use web access.
