# WeChat local history

Operate only on local WeChat data the user is authorized to access. Keep keys, decrypted databases, voice caches, and exports local. Never print a raw key or include one in chat, logs, commands, or reports.

## Resolve the runtime

Use the directory containing this `SKILL.md` as `SKILL_DIR`; never assume a fixed installation path.

- macOS: prefer `$SKILL_DIR/.venv/bin/python`, otherwise `python3`.
- Windows: prefer `$SKILL_DIR\.venv\Scripts\python.exe`, otherwise `python`.

Before reading chat data, run the read-only diagnostic:
