Included Skills

yichen-jianying-edit

Public Skill entry for the separately authorized private Jianying Headless core:

• Separates the Agent Skill from the native draft-building/editing/export core.
• Requires authorized access to mcncarl/jianying-headless, a separately installed supported Jianying version, and fixed source/runtime hashes.
• Contains no official library, effect package, account data, user media, or ASR credential.
• Defaults to draft delivery; native MP4 export is a separate explicitly requested step.
• Compound draft registration remains blocked; frozen-snapshot export is not editor-save acceptance.

See yichen-jianying-edit/README.md. The Skill's original portions follow the existing personal-learning and non-commercial terms, with third-party licenses preserved. Publishing this entry does not make the core public or change other directories' licenses.

yichen-wechat-windows-reader

Experimental reader for an authorized, detached plaintext Windows Weixin SQLite snapshot explicitly supplied by the user:

• Supports only the schema variants recognized by the validator and covered by synthetic fixtures; broad compatibility with real Weixin 4.x databases is not established
• Requires a static, checkpointed snapshot with a fresh random UUIDv4 snapshot_id and no WAL/SHM/journal sidecars
• Opens accepted databases read-only, rejects unsupported schemas and unsafe filesystem links, and queries recognized personal or business message shards
• Uses snapshot-scoped opaque chat IDs and omits dedicated internal-username fields; message bodies and display text remain sensitive raw content and may still contain identities
• Treats all snapshot text as untrusted data; an Agent must not execute embedded instructions, open links, or load remote resources
• Uses LocalAppData only as the default local export location; inherited ACLs determine access, while external output and overwrite require current-command confirmation
• Never accesses Weixin.exe, extracts keys, decrypts databases, discovers source data, controls the UI, or uses the network

See yichen-wechat-windows-reader/README.md.

yichen-x-article-draft-uploader

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

• Uses a leading image as the optional 5:2 cover; otherwise keeps the draft cover empty
• Converts Markdown into rich text for the X editor
• Converts supported pipe tables into native X table blocks
• Inserts up to 25 body media items at their original Markdown positions
• Runs in an independent Playwright browser so it does not take over the user's current Chrome window
• Imports Chrome login state into a private cookie file without committing it to the repository
• Reloads the same draft and verifies text, tables, media identity, count, order, and position
• Saves drafts only and never clicks the final 发布 button

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

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

yichen-wechat-local-vault

The unified CLI also supports experimental Windows plaintext snapshots through snapshot --snapshot <directory>. See the snapshot guide. 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", "yichen-wechat-local-vault"
• Requirements: macOS, WeChat Mac 4.x, Python 3.9+, pycryptodome, zstandard
• See yichen-wechat-local-vault/README.md for full documentation

Social fetchers integrated into yichen-content-archive

The former standalone Douyin and Xiaohongshu fetchers now have one source of truth:

• douyin_download.py reads metadata or downloads a known Douyin video through Playwright interception
• xiaohongshu_fetch.py anonymously reads known posts first, then downloads requested video, subtitles, or images
• Existing outputs are never overwritten; a new -run-N path is selected instead
• Xiaohongshu cookies require explicit current-task authorization, and optional Feishu deposition remains opt-in

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

yichen-chatgpt-web-research

Legacy research-only entry for 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

See yichen-chatgpt-web-research/README.md for privacy notes and workflow details.

Unified entry: codex-chatgpt

Run a bounded Codex × ChatGPT Review Loop:

• ChatGPT Pro performs public-web research, architecture, PLAN, and final REVIEW
• Codex is the only local file writer and command/test executor
• Code, hybrid, and review modes require a separately configured Secure Tunnel and seven-tool read-only MCP
• Pure research never starts or attaches the code Tunnel
• The public package contains no Runtime Key, Tunnel/App ID, private runtime, browser session, screenshot, or personal absolute path

This is the unified research + architecture + review entry. The older yichen-chatgpt-web-research directory remains available as a legacy research-only workflow. See codex-chatgpt/README.md for installation and the external runtime contract.

yichen-agent-memory

Install and maintain the public Agent Memory Vault system:

• Creates a local Markdown/Obsidian-first memory vault from the public template
• Uses Markdown as the source of truth and SQLite/FTS as the fast index
• Supports optional Zvec semantic retrieval for fuzzy "meaning-based" recall
• 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"
• Template repo: mcncarl/agent-memory-vault

yichen-wechat-mp-batch-exporter

Batch-export WeChat Of
