-# Himalaya 2 email
+# Email (universal-email)
+
+## Serve the user the Cola way
+
+These rules govern everything you SAY. They never change which commands you RUN — all operations below stay exactly as written.
+
+- **Product words are fine.** 配置、授权、连接、账号、授权码/App 专用密码 — the user should always know which step they are in.
+- **Implementation details never reach the user.** `himalaya`, CLI, config files, TOML, IMAP/SMTP, PATH, keychain service names — say “你的邮箱 / 邮件账户 / your mailbox” instead. If the user explicitly asks how it works, then you may explain.
+- **Narrate by goal, not by tooling.** “正在连接你的邮箱” “正在看你的收件箱”, never “running himalaya account list”.
+- **Ask for the minimum, once.** Ask for the email address. A well-known domain identifies the provider; a company or custom domain does not — it is often hosted on Google Workspace, Microsoft 365 or iCloud, and treating it as a generic mailbox would ask for server settings the user does not have and skip the provider's own sign-in. Check the domain's MX records, or simply ask which service hosts it, before choosing a guide. Then guide the user to generate the provider's app credential (QQ: 设置→账户→开启 IMAP/SMTP 生成授权码; iCloud/Gmail: App 专用密码, links allowed). Do not ask again unless verification actually failed.
+- **Credentials never enter the conversation.** An app password or authorization code must reach the secure local prompt, never a chat message and never a shell argument — a credential pasted into chat stays in the transcript. Ask the user to re-run the setup and enter the new code there; if they paste one anyway, use it once, then tell them to revoke and regenerate it.
+- **Translate errors into next steps.** Never paste raw command output or stack traces. Turn failures into one clear user action (“这个授权码好像不对，去 QQ 邮箱设置里重新生成一个，我这就帮你重新连”).
+- **Confirm in user terms.** Finish with what they can now do (“邮箱连好了，以后直接说『看看今天的邮件』就行”), not with what was configured where.
 
 Use the bundled `himalaya` executable. This Skill targets exactly Himalaya `2.0.0` at revision `923414155f4281d681f4ea8631954f406acf51ee`; do not use Himalaya 1.x configuration fields or command examples.
 
-Always invoke `himalaya` from `PATH`. Treat that command's active configuration as the source of truth: do not bypass it with the packaged binary's absolute path, inspect candidate config files to choose one, or add `--config` merely because a file exists. Use `--config` only when the user explicitly requests a separate profile.
+## Locate the executable
+
+Always use the copy bundled with this Skill; never a `himalaya` that happens to be on `PATH`, which may be an unrelated version. Resolve it once per session:
+
+1. Determine the platform directory — on macOS run `uname -m` (`arm64` → `darwin-arm64`, `x86_64` → `darwin-x64`); on Windows use `win32-x64`.
+2. Resolve `scripts/bin/<platform>/himalaya` against this document's directory — on Windows the file is `himalaya.exe` — and use that absolute path for every command below.
+
+This package ships macOS and Windows builds only. On any other platform there is no bundled copy, so fall back to a `himalaya` on `PATH` **after** confirming `himalaya --version` reports `v2.0.0`; a different version there is unusable and should be reported as such.
+
+The examples below write the command by its bare name for readability; always run the resolved absolute path instead.
+
+If that file is missing, report that the mailbox is not ready yet — never describe it as an account problem or a broken connector.
+
+Treat the active configuration of the executable you invoke as the source of truth: do not inspect candidate config files to choose one, or add `--config` merely because a file exists. Use `--config` only when the user explicitly requests a separate profile.

 ## Network and troubleshooting
 
-Himalaya 2 can inherit proxy routing from the current process or operating system and supports SOCKS5 and HTTP CONNECT. Discover the device's actual settings and preserve the reported protocol. Never infer a proxy protocol from a port number.
+Himalaya 2 supports SOCKS5 and HTTP CONNECT, and takes its route **only** from the environment of each invocation. Operating-system proxy settings are a discovery source, not a route: a proxy configured in macOS or Windows settings but absent from the process environment is not used, so reading it and then running the command unchanged tests the direct route while appearing to test the proxy. To exercise a discovered setting, pass it explicitly in that invocation's environment, and preserve the protocol exactly as reported — never infer one from a port number.
+
+Himalaya has no proxy configuration field or CLI flag: the route comes only from the environment of each invocation, and this build reads exactly two variables — `all_proxy` first, then `https_proxy`. **`http_proxy` is not consulted at all**, so a proxy supplied only through it is silently ignored and the command runs direct; carry such a value over into `https_proxy` for the invocation. This environment is the one lever for per-command route isolation. To force a single command onto the direct route, clear both variables for that invocation only, without touching the user's global proxy. On macOS use `env -u all_proxy -u https_proxy <himalaya> --account <name> ...`; in PowerShell, `env` does not exist, so scope the change to the process instead:
+
+```powershell
+# A child process, so the user's proxy stays intact in this session.
+powershell -NoProfile -Command @'
+Remove-Item Env:all_proxy -ErrorAction SilentlyContinue
+Remove-Item Env:https_proxy -ErrorAction SilentlyContinue
+& '<himalaya>' --account <name> ...
