Included Skills

1) yichen-summary

• Purpose: extract key insights from the current conversation and save to Obsidian
• Typical triggers: /yichen-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) yichen-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 yichen-x-article-draft-uploader/README.md for installation, privacy notes, and troubleshooting.

3) yichen-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)

• 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”, “yichen-wechat-local-vault”
• Requirements: macOS, WeChat Mac 4.x, Python 3.9+, pycryptodome, zstandard

6) yichen-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) yichen-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) yichen-chatgpt-web-research

Run research through the user’s already signed-in official ChatGPT website account:

• Uses the real ChatGPT web page, not the OpenAI API or a separate account
• Prefers Chrome extension control and falls back to visible Computer Use only when necessary
• Waits for a full answer with a unique marker before extracting
• Saves raw and readable Markdown reports under the current workspace’s reports/ directory
• Keeps profile names, local paths, cookies, tokens, and browser storage out of the public skill

10) yichen-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 yichen-volc-asr

11) yichen-agent-memory

Install and maintain the public Agent Memory Vault system:

• Guides prewrite reconcile, closeout, audit, and privacy-safe template updates
• Typical triggers: “install Agent Memory Vault”, “set up memory vault”, “run memory closeout”, “audit my Agent Memory Vault”

See yichen-wechat-mp-batch-exporter/README.md for setup and privacy notes.

13) yichen-wecom-local-vault

Read, decrypt, query, and export local WeCom/企业微信 5.x desktop databases on macOS:

• Creates private, timestamped plaintext snapshots and never writes back to the WeCom container

2. Start a new session and run /yichen-summary
3. Confirm output is written to your Obsidian folder (example paths may use /...)

B) Enable yichen-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 yichen-x-article-draft-uploader/README.md for commands

C) Enable yichen-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 yichen-mac-wechat-dual-open/SKILL.md for all commands

D) Enable yichen-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 yichen-wechat-local-vault/README.md for details

E) Enable the creator video workflow

1. Install Playwright, requests, and ffmpeg
2. Use yichen-douyin-fetcher or yichen-xiaohongshu-fetch to save benchmark media locally
