Key Concepts

核心概念

Before diving in, a few things about LINE's architecture:

MIDs = LINE's unique identifiers. Format varies by entity type:

u<32hex>

for users (e.g.,

u0123456789abcdef0123456789abcdef

)

c<32hex>

for groups (e.g.,

c0123456789abcdef0123456789abcdef

)

r<32hex>

for rooms (e.g.,

r0123456789abcdef0123456789abcdef

)

QR code login = the primary authentication method. The CLI generates a QR code URL, you scan it with your phone, and the session is established.
Email/password login = an alternative when QR scanning isn't practical.
Auth token reuse = after initial login, the CLI stores an auth token locally. Subsequent commands reuse it without re-authentication.
Device types = the CLI registers as
```
ANDROIDSECONDARY
```
by default — a secondary device that coexists with the LINE desktop app. Override with
```
--device
```
:
- ```
ANDROIDSECONDARY
```
  (default) — secondary device, V3-capable, won't kick LINE desktop
- ```
DESKTOPMAC
```
  /
```
DESKTOPWIN
```
  — replaces the desktop session (kicks LINE desktop app)
- ```
IOSIPAD
```
  — secondary but limited API (no V3 token refresh)
Chat ID = an MID that identifies a conversation. Use
```
chat list
```
to discover them.

开始使用前，先了解LINE的一些架构知识：

MIDs = LINE的唯一标识符，格式根据实体类型不同而有所区别：
- ```
u<32hex>
```
  代表用户（例如：
```
u0123456789abcdef0123456789abcdef
```
  ）
- ```
c<32hex>
```
  代表群组（例如：
```
c0123456789abcdef0123456789abcdef
```
  ）
- ```
r<32hex>
```
  代表聊天室（例如：
```
r0123456789abcdef0123456789abcdef
```
  ）
二维码登录 = 主要认证方式。CLI生成一个二维码URL，用户用手机扫描即可建立会话。
邮箱/密码登录 = 二维码扫描不可用时的替代方案。
认证令牌复用 = 首次登录后，CLI会在本地存储认证令牌，后续命令可复用该令牌无需重新认证。
设备类型 = CLI默认注册为
```
ANDROIDSECONDARY
```
——这是一种可与LINE桌面应用共存的辅助设备。可通过
```
--device
```
参数覆盖：
- ```
ANDROIDSECONDARY
```
  （默认）——辅助设备，支持V3协议，不会强制下线LINE桌面应用
- ```
DESKTOPMAC
```
  /
```
DESKTOPWIN
```
  ——会替换桌面会话（强制下线LINE桌面应用）
- ```
IOSIPAD
```
  ——辅助设备但API受限（不支持V3令牌刷新）
聊天ID = 用于标识对话的MID。使用
```
chat list
```
命令查看所有聊天ID。

Authentication

认证方式

LINE offers three authentication methods:

LINE提供三种认证方式：

Method 1: QR Code Login (Recommended)

方式1：二维码登录（推荐）

The default and most common method. No credentials needed.

bash

agent-line auth login

The CLI prints a QR code URL to stderr. The user scans it with the LINE app on their phone. Once scanned, authentication completes automatically.

Flow:

CLI requests a QR code session from LINE's server
A URL is printed to stderr (e.g.,
```
https://line.me/R/au/q/...
```
)
User scans the QR code with their LINE mobile app
CLI detects the scan and completes login
Auth token is stored locally for future use

默认且最常用的方式，无需输入凭据。

bash

agent-line auth login

CLI会在标准错误输出中打印二维码URL，用户使用手机上的LINE应用扫描该二维码，扫描完成后认证自动完成。

流程：

CLI向LINE服务器请求二维码会话
在标准错误输出中打印URL（例如：
```
https://line.me/R/au/q/...
```
）
用户使用LINE移动应用扫描二维码
CLI检测到扫描完成并完成登录
认证令牌存储在本地供后续使用

Method 2: Email/Password Login

方式2：邮箱/密码登录

For environments where QR scanning isn't possible:

bash

agent-line auth login --email user@example.com --password pass123

适用于无法扫描二维码的环境：

bash

agent-line auth login --email user@example.com --password pass123

Method 3: Token Login

方式3：令牌登录

If you already have a valid auth token:

bash

agent-line auth login --token <auth-token>

如果已有有效的认证令牌：

bash

agent-line auth login --token <auth-token>

Device Override

设备类型覆盖

To specify a device type explicitly:

bash

agent-line auth login --device DESKTOPMAC
agent-line auth login --device DESKTOPWIN

显式指定设备类型：

bash

agent-line auth login --device DESKTOPMAC
agent-line auth login --device DESKTOPWIN

Agent Behavior (MANDATORY)

Agent行为规范（必须遵守）

When a command fails because no account is configured, the agent MUST drive the auth flow itself:

Step 1: Check auth status

bash

agent-line auth status

If authenticated, retry the original command.

Step 2: Attempt login

bash

agent-line auth login

Possible responses:

```
{"authenticated": true, ...}
```
→ Success. Retry original command.
```
{"next_action": "scan_qr", "qr_url": "...", "qr_html_path": "/tmp/line-qr-xxx.html", ...}
```
→ QR code has been generated. The CLI attempts to open it in the user's browser automatically. If it didn't open, run
```
open <qr_html_path>
```
(macOS) to show the QR code. Tell the user to scan the QR code with the LINE mobile app. The command blocks until the user scans — once scanned, it outputs
```
{"authenticated": true, ...}
```
.
```
{"error": "not_connected", ...}
```
→ Network issue. Check connectivity and retry.

{"error": "not_authenticated", ...}

→ Credentials expired. Re-run

auth login

Important: QR login works in both interactive and non-interactive (agent) sessions. The CLI generates an HTML page with the QR code and opens it in the user's default browser. No TTY is required.

Step 3: Retry the original command

After successful auth, immediately execute whatever the user originally asked for.

IMPORTANT: NEVER guide the user to open a web browser, use DevTools, or manually copy tokens. Always use

agent-line auth login

当命令因未配置账户而失败时，Agent必须自动驱动认证流程：

步骤1：检查认证状态

bash

agent-line auth status

如果已认证，重试原命令。

步骤2：尝试登录

bash

agent-line auth login

可能的响应：

```
{"authenticated": true, ...}
```
→ 登录成功，重试原命令。
```
{"next_action": "scan_qr", "qr_url": "...", "qr_html_path": "/tmp/line-qr-xxx.html", ...}
```
→ 已生成二维码。CLI会尝试自动在用户浏览器中打开二维码页面。如果未自动打开，可运行
```
open <qr_html_path>
```
（macOS）显示二维码。告知用户使用LINE移动应用扫描二维码，命令会阻塞直至用户完成扫描——扫描完成后会输出
```
{"authenticated": true, ...}
```
。
```
{"error": "not_connected", ...}
```
→ 网络问题，检查网络连接后重试。

{"error": "not_authenticated", ...}

→ 凭据过期，重新运行

auth login

命令。

重要提示：二维码登录在交互式和非交互式（Agent）会话中均有效。CLI会生成包含二维码的HTML页面并在用户默认浏览器中打开，无需TTY。

步骤3：重试原命令

认证成功后，立即执行用户最初请求的操作。

重要注意事项：绝对不要引导用户打开浏览器开发者工具或手动复制令牌，必须始终使用

agent-line auth login

命令。

Memory

内存管理

The agent maintains a

~/.config/agent-messenger/MEMORY.md

file as persistent memory across sessions. This is agent-managed. The CLI does not read or write this file. Use the

Read

and

Write

tools to manage your memory file.

Agent会维护一个

~/.config/agent-messenger/MEMORY.md

文件，作为跨会话的持久化存储。该文件由Agent管理，CLI不会读写此文件。使用

Read

和

Write

工具管理内存文件。

Reading Memory

读取内存

At the start of every task, read

~/.config/agent-messenger/MEMORY.md

using the

Read

tool to load any previously discovered chat IDs, friend names, and preferences.

If the file doesn't exist yet, that's fine. Proceed without it and create it when you first have useful information to store.
If the file can't be read (permissions, missing directory), proceed without memory. Don't error out.

在每个任务开始时，使用

Read

工具读取

~/.config/agent-messenger/MEMORY.md

，加载之前保存的聊天ID、好友名称和用户偏好。

如果文件尚未存在，无需处理，继续执行任务，当有有用信息时再创建该文件。
如果无法读取文件（权限问题、目录缺失），无需报错，继续执行任务。

Writing Memory

写入内存

After discovering useful information, update

~/.config/agent-messenger/MEMORY.md

using the

Write

tool. Write triggers include:

After login, remember the
```
account_id
```
from the output
After discovering chat IDs and participant names (from
```
chat list
```
)
After the user gives you an alias or preference ("call this the work chat", "my group chat with Alice is X")
After discovering chat structure (group chats, 1:1 chats)

When writing, include the complete file content. The

Write

tool overwrites the entire file.

发现有用信息后，使用

Write

工具更新

~/.config/agent-messenger/MEMORY.md

。触发写入的场景包括：

登录完成后，保存输出中的
```
account_id
```
发现聊天ID和参与者名称后（来自
```
chat list
```
命令）
用户设置别名或偏好后（例如："将这个聊天称为工作群"、"我和Alice的群聊ID是X"）
发现聊天结构后（群组、一对一聊天）

写入时需包含完整的文件内容，

Write

工具会覆盖整个文件。

What to Store

存储内容

Account ID (MID) from login
Chat IDs with participant names or display names
User-given aliases ("work chat", "family group")
Commonly referenced chat IDs
Any user preference expressed during interaction

登录时获取的账户ID（MID）
带有参与者名称或显示名的聊天ID
用户设置的别名（例如："工作群"、"家庭群"）
常用的聊天ID
交互过程中用户表达的任何偏好

What NOT to Store

禁止存储内容

Never store tokens, passwords, credentials, or any sensitive data. Never store full message content (just IDs and chat context). Never store auth tokens.

绝对不要存储令牌、密码、凭据或任何敏感数据。不要存储完整消息内容（仅存储ID和聊天上下文）。不要存储认证令牌。

Handling Stale Data

处理过期数据

If a memorized chat ID returns an error, remove it from

MEMORY.md

. Don't blindly trust memorized data. Verify when something seems off. Prefer re-listing over using a memorized ID that might be stale.

如果保存的聊天ID返回错误，将其从

MEMORY.md

中删除。不要盲目信任保存的数据，当出现异常时进行验证。优先重新列出聊天ID，而非使用可能过期的保存ID。

> Memory lets you skip repeated `chat list` calls. When you already know a chat ID from a previous session, use it directly.

用户偏好使用--pretty输出
工作群聊是最常用的聊天


> 内存功能可避免重复调用`chat list`命令。如果已从之前的会话中获取聊天ID，可直接使用。

Troubleshooting

故障排除

agent-line: command not found

agent-line: command not found

agent-line
is NOT the npm package name. The npm package is

agent-messenger

If the package is installed globally, use

agent-line

directly:

bash

agent-line chat list --pretty

If the package is NOT installed, use

--package

to install and run:

bash

npx -y --package agent-messenger agent-line chat list --pretty
bunx --package agent-messenger agent-line chat list --pretty
pnpm dlx --package agent-messenger agent-line chat list --pretty

Note: If the user prefers a different package runner, use the matching command above.

NEVER run
npx agent-line
,
bunx agent-line
, or
pnpm dlx agent-line
without

--package agent-messenger

. It will fail or install a wrong package since

agent-line

is not the npm package name.

agent-line
不是npm包名称，npm包名称为

agent-messenger

。

如果已全局安装该包，可直接使用

agent-line

：

bash

agent-line chat list --pretty

如果未安装该包，使用

--package

参数安装并运行：

bash

npx -y --package agent-messenger agent-line chat list --pretty
bunx --package agent-messenger agent-line chat list --pretty
pnpm dlx --package agent-messenger agent-line chat list --pretty

注意：如果用户偏好其他包管理器，使用上述对应命令。

**绝对不要运行

npx agent-line

、

bunx agent-line

或

pnpm dlx agent-line

**而不添加

--package agent-messenger

参数，这会导致失败或安装错误的包，因为

agent-line

不是npm包名称。
