使用说明 (SKILL.md)

Pywayne Lark Custom Bot

飞书自定义机器人模块,用于通过 webhook 向飞书渠道发送消息。

Quick Start

from pywayne.lark_custom_bot import LarkCustomBot

# 初始化
bot = LarkCustomBot(
    webhook="your_webhook_url",
    secret="your_secret",  # 可选,用于签名验证
    bot_app_id="your_app_id",  # 上传图片时需要
    bot_secret="your_app_secret"  # 上传图片时需要
)

# 发送文本
bot.send_text("Hello, 飞书!")

# 发送文本并 @所有人
bot.send_text("重要通知!", mention_all=True)

Message Types

Text Message

发送纯文本消息。

bot.send_text("这是一条文本消息")
bot.send_text("@所有人请注意", mention_all=True)

Image Message

发送图片消息,需要先上传获取 image_key

# 从文件上传
image_key = bot.upload_image("/path/to/image.jpg")
bot.send_image(image_key)

# 从 OpenCV 图像上传
import cv2
cv2_img = cv2.imread("/path/to/image.jpg")
image_key = bot.upload_image_from_cv2(cv2_img)
bot.send_image(image_key)

注意: 上传图片需要配置 bot_app_idbot_secret

Rich Text Post

发送富文本消息,支持文本、链接、@用户、图片等元素。

from pywayne.lark_custom_bot import (
    create_text_content,
    create_link_content,
    create_at_content,
    create_image_content
)

content = [
    [create_text_content("欢迎使用飞书机器人\
")],
    [create_link_content(href="https://www.feishu.cn", text="点击访问飞书")],
    [create_at_content(user_id="user_id", user_name="用户名")],
    [create_image_content(image_key="img_xxx", width=400, height=300)]
]

bot.send_post(content, title="富文本消息标题")

Interactive Card

发送交互式卡片消息。

card = {
    "header": {
        "title": {
            "content": "卡片标题",
            "tag": "plain_text"
        }
    },
    "elements": [
        {
            "tag": "div",
            "text": {
                "tag": "plain_text",
                "content": "卡片内容"
            }
        }
    ]
}
bot.send_interactive(card)

Share Chat

分享会话。

bot.send_share_chat(share_chat_id="oc_xxxxxxxxxxxxxxxx")

Content Builders

create_text_content

创建文本内容元素。

create_text_content("文本内容", unescape=False)

create_link_content

创建超链接内容元素。

create_link_content(href="https://example.com", text="点击访问")

create_at_content

创建 @用户内容元素。

create_at_content(user_id="user_id", user_name="用户名")

create_image_content

创建图片内容元素。

create_image_content(image_key="img_xxx", width=400, height=300)

Authentication

Signature Verification

为增强安全性,可配置 secret 进行签名验证:

bot = LarkCustomBot(
    webhook="your_webhook_url",
    secret="your_signing_secret"
)

Image Upload Authentication

上传图片需要应用凭证:

bot = LarkCustomBot(
    webhook="your_webhook_url",
    bot_app_id="cli_xxxxxxxxxxxxxxxx",
    bot_secret="xxxxxxxxxxxxxxx"
)

Error Handling

所有方法内部已实现日志记录和异常处理。发送失败时会记录错误日志并抛出 requests.RequestException

安全使用建议
This SKILL.md documents a Python library but the bundle contains no code or install instructions and the source/homepage are unknown — treat it as incomplete and untrusted. Before installing or using it: 1) ask the publisher for the package source (PyPI name or repository) and an install spec (pip, git URL, or wheel); 2) review the package source code or trust signals (repo, maintainer, releases) before running it; 3) if you must test, do so in an isolated environment/container and avoid reusing production credentials; 4) for image upload features, create a minimal-scope bot credential, rotate it after testing, and avoid giving global account keys; 5) if the publisher cannot provide source or an install artifact, consider the skill untrusted and do not provide secrets.
功能分析
Type: OpenClaw Skill Name: lark-custom-bot Version: 0.1.0 The skill bundle describes a Feishu/Lark Custom Bot API wrapper. The `SKILL.md` provides clear, functional instructions and code examples for sending various message types and uploading images, which inherently involves network communication and file access. There are no indicators of prompt injection attempts, data exfiltration, malicious execution, persistence mechanisms, or obfuscation. All described functionalities are aligned with the stated purpose of a messaging bot skill.
能力评估
Purpose & Capability
The stated purpose (Feishu/Lark webhook wrapper) aligns with the instructions (sending text, images, posts, cards). However the SKILL.md assumes an importable Python package (pywayne.lark_custom_bot) and runtime behavior that require a library to be present; the skill bundle contains no code, no declared dependencies, and no install spec to provide that library or justify its permissions.
Instruction Scope
The instructions themselves stay on-topic (constructing and sending messages, uploading images, signature verification). They reference local files and OpenCV images for uploads and require bot app credentials for image upload — these are coherent with the feature set and do not instruct reading unrelated system files or exfiltrating data. The main issue is that the instructions assume a third-party Python module is available.
Install Mechanism
There is no install spec and no code files. SKILL.md examples import pywayne.lark_custom_bot, but the package source, distribution channel (PyPI, GitHub, etc.), and installation steps are missing. That gap makes it unclear how the code would be obtained or vetted — a material traceability and supply-chain concern.
Credentials
The skill declares no required env vars and no primary credential, which is consistent with examples that pass credentials into the LarkCustomBot constructor. However, image uploads require bot_app_id and bot_secret (sensitive credentials) according to the docs; the skill does not recommend how to provide or securely store these, nor does it declare them as required variables for the skill. Users should not provide long-lived secrets to an unknown package without provenance.
Persistence & Privilege
No persistent installation or elevated privileges are requested by the skill bundle (always:false). There is no indication the skill modifies other skills or system-wide settings. Autonomous invocation remains allowed (platform default) but is not combined here with other privilege escalation indicators.
如何使用
  1. 确保已安装 OpenClaw(本地或 Docker 部署)
  2. 在对话框中输入安装命令:/install lark-custom-bot
  3. 安装完成后,直接呼叫该 Skill 的名称或使用 /lark-custom-bot 触发
  4. 根据 Skill 的参数说明提供必要输入,即可获得结构化输出
