When you connect these two GitHub projects with Codex, data archiving takes off immediately. One manages WeChat, the other manages Feishu:

• WeChat Local Vault: https://github.com/mcncarl/yichen-skills/tree/main/wechat-local-vault…
• Feishu CLI: https://github.com/larksuite/cli

The former turns WeChat chats, favorites, and Moments into local assets that can be called by AI; the latter is Feishu’s official CLI, covering office scenarios like messages, documents, spreadsheets, and calendars.

English | 中文

A skill collection for creators who want to streamline writing, X Articles draft publishing, WeChat digital-asset capture, and local workflows with Claude Code and Codex.

What This Repo Does

1. Turn Claude Code conversations into structured Obsidian notes (summary)
2. Upload Obsidian/Markdown articles to X Articles drafts (x-article-draft-uploader)
3. Turn WeChat chats, Moments, and Favorites into AI-powered digital assets (wechat-local-vault)
4. Run two WeChat accounts on one Mac with a distinct blue icon (mac-wechat-dual-open)
5. Fetch benchmark videos/posts from Douyin and Xiaohongshu (douyin-fetcher, xiaohongshu-fetch)
6. Transcribe, caption, and rough-cut talking-head videos with Volcengine ASR (volc-asr)
7. Diagnose benchmark video transcripts (yichen-video-content)
8. Hand off rough cuts to Jianying/CapCut for final editing (jianying-editor)

Included Skills

1) summary

• Purpose: extract key insights from the current conversation and save to Obsidian
• Typical triggers: /summary, “save conversation”, “export highlights”
• Capabilities:
  • Filters out low-value chat transitions
  • Produces structured notes (Background, Core Content, Solution, Key Points, Related)
  • Useful for long-term knowledge accumulation

2) x-article-draft-uploader

Upload Obsidian/Markdown long-form articles to X Articles drafts:

• Uses the first image as the X Article cover
• Converts Markdown into rich text for the X editor
• Inserts body images at their original Markdown positions
• Runs in an independent Playwright browser so it does not take over the user’s current Chrome window
• Reuses Chrome login state through temporary exported cookies
• Saves drafts only and does not click the final 发布 button

See x-article-draft-uploader/README.md for installation, privacy notes, and troubleshooting.

3) mac-wechat-dual-open

Run two WeChat accounts simultaneously on macOS — no third-party tools:

• Copies WeChat, changes the bundle identifier, and re-signs locally
• Recolors the second app’s icon from green to blue for visual distinction
• Handles both outer and embedded icon files, Finder custom icon, and cache refresh
• One-command workflow: create → recolor-icon → launch
• Typical triggers: “微信双开”, “WeChat dual open”, “double WeChat”
• Requirements: macOS 12+, WeChat at /Applications/WeChat.app, Python 3.10+, Pillow
• Limitations: breaks after WeChat updates (re-run repair), push notifications may be unreliable
• Based on the well-known copy + bundle-id + ad-hoc signing method documented by @koffuxu (https://x.com/koffuxu/status/2043110831584690427)

4) wechat-local-vault

WeChat digital-asset assistant for macOS:

• Decrypts WeChat Mac 4.x local SQLCipher databases (AES-256-CBC)
• Extracts chats, Moments (sns.db), and Favorites (favorite.db)
• Generates AI-powered chat digests, Moments reports, Favorites cleanup notes, customer follow-up drafts, and relationship review prompts
• First-time onboarding introduces 3 categories and 9 playbooks: chat records, Moments, and Favorites
• Configurable monitoring for groups, contacts, Moments targets, and Favorites cleanup preferences
• First-time setup guided via frida key extraction
• Typical triggers: “微信解析”, “微信全量”, “微信增量”, “导出聊天”, “朋友圈解析”, “收藏夹整理”, “客户跟进”, “wechat-local-vault”
• Requirements: macOS, WeChat Mac 4.x, Python 3.9+, pycryptodome, zstandard
• See wechat-local-vault/README.md for full documentation

5) douyin-fetcher

Fetch Douyin video metadata and download an MP4 through Playwright network interception:

• Supports /video/ links and selected modal-style URLs
• Writes a compact .metadata.json next to the downloaded video
• Use --metadata-only to validate a link without downloading media

6) xiaohongshu-fetch

Fetch Xiaohongshu video/image posts into local files:

• Parses window.__INITIAL_STATE__
• Downloads video, subtitles, images, and metadata when available
• Keeps cookies, Feishu AppToken/TableID, and target table IDs out of the repo

7) volc-asr

Transcribe local audio/video files and generate rough cuts:

• Uses environment variables for Volcengine ASR and TOS configuration
• Produces transcript text, SRT subtitles, ASR cache, and optional rough-cut MP4
• Requires explicit user approval before cleaning temporary files

8) yichen-video-content

Analyze benchmark video transcripts:

• Breaks a transcript down sentence by sentence
• Labels each sentence’s role
• Produces a structured imitation and improvement report

9) jianying-editor

Guide Jianying/CapCut desktop finishing:

• Confirms media files and imports rough cuts
• Handles timeline placement, subtitles, visual polishing, and export notes
• Leaves automatic rough-cut logic to volc-asr

Installation

Copy this repository into your local skills directory:

• Common Claude path: ~/.claude/skills/
• Common Agents path: ~/.agents/skills/
• Custom skill path also works if your setup supports it

Keep directory names unchanged:

• summary
• x-article-draft-uploader
• wechat-local-vault
• mac-wechat-dual-open
• douyin-fetcher
• xiaohongshu-fetch
• volc-asr
• yichen-video-content
• jianying-editor

Quick Start (3 Minutes)

A) Enable summary

1. Ensure summary/SKILL.md is available in your loaded skills path
2. Start a new session and run /summary
3. Confirm output is written to your Obsidian folder (example paths may use /...)

B) Enable x-article-draft-uploader

1. Install Python Playwright: pip3 install playwright pycryptodome && python3 -m playwright install chromium
2. Make sure Chrome is already logged in to X
3. Say “upload this Markdown article to X Articles draft” or run the script directly
4. The skill creates a fresh draft, preserves the first image as the cover, and inserts body images in place
5. See x-article-draft-uploader/README.md for commands

C) Enable mac-wechat-dual-open

1. Install Python dependency: pip3 install Pillow
2. In Claude Code, say “帮我微信双开” or “WeChat dual open”
3. The skill will create a second WeChat at ~/Applications/WeChat-2.app with a blue icon
4. See mac-wechat-dual-open/SKILL.md for all commands

D) Enable wechat-local-vault

1. Install Python dependencies: pip3 install pycryptodome zstandard
2. In Claude Code or Codex, say “微信解析”, “导出聊天”, or “收藏夹整理”
3. First run will guide you through key extraction and choosing among the 9 playbooks
4. If unsure, start with the recommended trio: group chat digest + Moments report + Favorites cleanup
5. Subsequent runs generate the selected digest, report, or draft workflow
6. See wechat-local-vault/README.md for details

E) Enable the creator video workflow

1. Install Playwright, requests, and ffmpeg
2. Use douyin-fetcher or xiaohongshu-fetch to save benchmark media locally
3. Use volc-asr to transcribe or rough-cut recorded talking-head videos
4. Use yichen-video-content to diagnose benchmark transcripts
5. Use jianying-editor for final Jianying/CapCut import, subtitle, polish, and export steps

X Cookie Handling

This repo does not include real credentials or cookie templates. x-article-draft-uploader exports current X cookies from the user’s local Chrome profile into a temporary Playwright cookie file:

python3 ~/.codex/skills/x-article-draft-uploader/scripts/export_x_cookies_from_chrome.py --output /tmp/x_current_cookies.json

The temporary file is sensitive and should be deleted after use:

rm -f /tmp/x_current_cookies.json

.gitignore already ignores **/cookies.json.

Security Notes

• Real token/cookie values are not included
• History/cache artifacts are excluded from tracking
• Personal absolute paths are replaced with generic forms
• Third-party AppID, AppToken, TableID, bucket names, and ASR tokens must be supplied through environment variables or private config

If you ever exposed real cookies in a public repo, rotate them immediately.

FAQ

Why doesn’t a skill trigger?

• Verify the skill folder is in your actually loaded skill path
• Restart the session and retry
• Check name and description in SKILL.md frontmatter

Why did X Articles draft upload fail?

• Check whether Chrome is still logged in to X
• Re-export temporary cookies
• Verify Python Playwright is installed
• Verify local Markdown/image paths exist

Can I use my own Obsidian path?

• Yes. Replace example paths in skill files
• /... is only an example
