baoyu-wechat-summary Skill (JimLiu) for Claude: What It Does and How to Install It

• Discovers your own wxid and writes EXTEND.md

  Tries wx whoami, then your own sent messages, to pre-fill your wxid and display name, then asks you to confirm and saves preferences to EXTEND.md.

  Write · First-time setup

• Reads messages for a group and time range

  Runs wx history for the named group between two dates, through the local wx-cli daemon, which reads WeChat’s own data folder.

  Try: “Summarize the "产品群" chat from the last 7 days.”

  Runs code · Pull group history

• Structured summary with sections and a self-check

  Follows the section order and format in output-formats.md to write a readable recap of the period.

  Write · Normal digest

• Opt-in snarkier version of the same period

  Generated only when you ask for it, alongside or instead of the normal digest.

  Write · Roast (毒舌) digest

• Builds and updates a markdown file per group member

  Keeps separate profile folders for the normal and roast versions so roast commentary never leaks into the sober digest, per profiles.md.

  Write · Per-user profiles

• Records corrected facts group members pointed out

  Writes a fact only when it meets three conditions in group-memory.md: it corrects a specific claim, with a reason or evidence, and nobody disputed it. It always reports how many candidates it scanned and how many it wrote.

  Write · Group memory (memory.md)

• Rebuilds profiles from past history on request

  Runs when you ask to "回溯画像" or "初始化画像" (backfill or initialize profiles).

  Write · Backfill profiles

Watch out for

• Reads your real WeChat messages outside the sandbox

  SKILL.md says every wx command needs dangerouslyDisableSandbox: true because wx-cli reads ~/.wx-cli and WeChat’s own Containers data folder, both outside Claude Code’s default sandbox. Only run this where you are comfortable giving that access. github.com

• Other people's chat messages and a profile on each of them

  The digest is built from the group's messages, so what other members wrote enters your Claude session, and profiles.md keeps a markdown file per wxid with nicknames, tags and message counts. These people did not opt in. Output goes to {project_root}/wechat unless you set data_root in EXTEND.md; do not commit that folder. github.com

• First-time wx init may need a changed WeChat app signature

  setup.md tells you to run wx init while WeChat is running and, on macOS, to run `codesign --force --deep --sign - /Applications/WeChat.app` first. It prefers a non-sudo init and falls back to sudo only if your wx-cli version needs it. Those commands are yours to run; the skill hands them to you. github.com

• Group memory can record a disputed claim if unchecked

  group-memory.md sets a three-part bar before writing a fact (specific, backed by reason or evidence, undisputed) and requires the skill to report how many candidates it scanned versus wrote, so a silent skip is a deviation from spec. github.com

• Setup forbids auto-install and sudo, but asks you to run them

  setup.md tells the skill never to auto-install wx-cli or run sudo on your behalf; it hands you the exact npm install or chown/sudo command to run yourself. github.com
