What it does

Yichen Wechat Windows Reader is an agent skill from mcncarl/yichen-skills. 实验性 Windows 微信明文数据库快照本机只读查询与导出工具。用于验证用户已授权、已解密并脱离运行中客户端的静止快照,列出会话,按快照级匿名会话 ID 查询/搜索聊天和导出 Markdown。明确不读取 Weixin.exe 进程、不提取或保存密钥、不解密数据库、不发现源路径、不控制微信界面、不联网。触发词:Windows 微信明文快照、微信只读分析、查询微信快照、导出微信聊天、yichen-wechat-windows-reader。

Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts (for example `CONTRIBUTOR_GRANT.md`, `PROVENANCE.md` and `README.md`).

It sits in Productivity & Automation, covering Messaging and chat bots. It works with WeChat.

When your agent uses it

  • Tasks that involve Messaging and chat bots

Example prompts

  • “/yichen-wechat-windows-reader”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 9bd7898. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Yichen Wechat Windows Reader loads about 769 tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 124 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~769

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 124 words (~769 tokens).

“本 Skill 是实验性读取器,只支持验证器明确识别、合成 fixture 已覆盖的 schema;尚未证明全面兼容真实 Windows 微信 4.x 数据库。只分析用户当前任务明确授权并显式提供的、已经是标准 SQLite 明文格式、脱离运行中客户端的静止快照目录。不要寻找或复制微信数据目录,不要访问 Weixin.exe,不要读取进程内存,不要提取、接收、保存或验证数据库密钥,不要尝试 SQLCipher/WAL 解密,不要操控微信 UI,也不要联网。”
