Sugon-Scnet 机动车销售统一发票识别 OCR 技能\r
\r 本技能封装了 Sugon-Scnet 机动车销售统一发票识别 OCR 服务,通过单一接口即可调用 1 种识别能力,高效提取文字及票据信息。\r \r
功能特性\r
\r
- 机动车销售统一发票票据:覆盖机动车销售统一发票自动提取关键字段。\r \r
前置配置\r
\r
⚠️ 重要:使用前需要申请 Scnet API Token\r \r
申请 API Token\r
\r
- 访问 Scnet 官网 注册/登录\r
- 在控制台申请 API 密钥(格式:
sc-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx)\r - 复制密钥备用\r \r
配置 Token\r
\r 手动配置(推荐)\r
- 在技能目录下创建
config/.env文件,内容如下:\r
# ===== Sugon-Scnet OCR API 配置 =====\r
# 申请地址:https://www.scnet.cn\r
SCNET_API_KEY=your_scnet_api_key_here\r
\r
# API 基础地址(一般无需修改)\r
SCNET_API_BASE=https://api.scnet.cn/api/llm/v1\r
```\r
2. 添加:`SCNET_API_KEY=你的密钥`\r
3. 设置文件权限为 600(仅所有者可读写)\r
**⚠️ 安全警告**:切勿将 API Key 直接粘贴到聊天对话中,否则可能被记录或泄露。\r
\r
### Token 更新\r
\r
Token 过期后调用会返回 401 或 403 错误。更新方法:重新申请 Token 并替换 config/.env 中的 SCNET_API_KEY。\r
\r
### 依赖安装\r
\r
本技能需要 Python 3.6+ 和 requests 库。请运行以下命令:\r
\r
```bash\r
pip install requests\r
```\r
---\r
### 使用方法\r
\r
### 参数说明\r
\r
| 参数名 | 类型 | 必填 | 描述 |\r
|--------|------|------|------|\r
| ocrType | string | 是 | 识别类型枚举。必须为以下之一:\x3Cbr>• VEHICLE_SALE_INVOICE(机动车销售统一发票) |\r
| filePath | string | 是 | 待识别图片的本地绝对路径。支持 jpg、png、pdf 等常见格式。 |\r
\r
### 命令行调用示例\r
\r
```bash\r
python .claude/skills/car_sales_invoice_ocr/scripts/main.py VEHICLE_SALE_INVOICE /path/to/invoice.jpg\r
```\r
\r
### 在 AI 对话中使用\r
\r
用户可以说:\r
\r
- “提取这张发票的信息,路径是 /Users/name/Downloads/fapiao.png”\r
\r
AI 会根据 description 中的关键词自动触发本技能。\r
\r
### AI 调用建议\r
为避免触发 API 速率限制(10 QPS),请串行调用本技能,即等待前一个识别完成后再发起下一个请求。\r
如果使用 OpenClaw 的 exec 工具,建议设置 timeout 或 yieldMs 参数,让命令同步执行,避免多个命令同时运行导致并发。\r
\r
### 配置选项\r
\r
编辑 `config/.env` 文件:\r
\r
| 变量名 | 默认值 | 说明 |\r
|--------|--------|------|\r
| SCNET_API_KEY | 必需 | Scnet API 密钥 |\r
| SCNET_API_BASE | https://api.scnet.cn/api/llm/v1 | API 基础地址(一般无需修改) |\r
\r
### 输出\r
\r
- 标准输出:识别结果的 JSON 数据,结构与 API 文档一致,位于 `data` 字段内。\r
- 识别结果位于 data[0].result[0].elements 中,具体字段取决于 ocrType。\r
- 错误信息:如果发生错误,会输出以 `错误:` 开头的友好提示。\r
\r
### 注意事项\r
\r
- 本技能调用的 OCR API 有 10 QPS 的速率限制。\r
- 如果遇到 429 错误,请等待 2-3 秒后重试,不要连续发起请求。\r
- 建议在调用前确保图片已准备就绪,避免因网络问题导致重复调用。\r
### 故障排除\r
\r
| 问题 | 解决方案 |\r
|------|----------|\r
| 配置文件不存在 | 创建 config/.env 并填入 Token(参考前置配置) |\r
| API Key 无效/过期 | 重新申请 Token 并更新 `.env` 文件 |\r
| 文件不存在 | 检查提供的文件路径是否正确 |\r
| 网络连接失败 | 检查网络连接或防火墙设置 |\r
| 不支持的文件类型 | 确保文件扩展名为允许的类型(参考 API 文档) |\r
| 401/403/Unauthorized | Token 无效或过期,重新申请并配置 |\r
| 429 Too Many Requests | 请求过于频繁,技能会自动等待并重试(最多 3 次)。若持续失败,请降低调用频率或联系服务方提高限额。 |\r

Usage Guidance
This skill appears to do what it says: upload a local invoice image to the Scnet OCR API and return structured JSON. Before installing, confirm you trust the Scnet service (https://api.scnet.cn) and the skill author: the repository/homepage in the manifest is a placeholder and the source is marked unknown. Store SCNET_API_KEY securely (use environment variables or a protected config file with strict permissions) and never paste it into chat. Review the included scripts/main.py yourself (it's small and readable) and, in sensitive environments, ensure outbound network access to the API host is acceptable and permitted by policy because invoice images contain personal data (VIN, name, tax IDs). If you need stronger assurance, contact the skill author or use a private/enterprise OCR service you trust.
Capability Analysis
Type: OpenClaw Skill
Name: car-sales-invoice-ocr
Version: 1.0.3
The skill is a legitimate OCR tool for processing vehicle sales invoices via the Sugon-Scnet API. The core logic in `scripts/main.py` is well-structured, focusing on file uploads to a specific endpoint (api.scnet.cn), handling rate limits (429 errors) with backoff retries, and providing clear security warnings regarding API key management. No evidence of data exfiltration, malicious execution, or prompt injection was found.
Capability Tags
Capability Assessment
Purpose & Capability
Name/description, declared env vars (SCNET_API_KEY, optional SCNET_API_BASE), and the code all align: the script posts invoice image files to https://api.scnet.cn/api/llm/v1/ocr/recognize and returns structured JSON. There are no unrelated credentials, binaries, or config paths requested.
Instruction Scope
SKILL.md and scripts instruct the agent to read a local image path and a local config/.env (or environment variable) for the SCNET_API_KEY, then upload the file to the Scnet OCR API. The instructions do not ask the agent to read other system files, secrets, or send data to unexpected endpoints.
Install Mechanism
No install spec or external downloads are included; only a small Python script is bundled and requires standard Python + requests. This is proportionate for an included helper script.
Credentials
Only a single service credential (SCNET_API_KEY) is required and an optional base URL; that matches the described external API usage. No extraneous SECRET/TOKEN/PASSWORD variables or unrelated service credentials are requested.
Persistence & Privilege
The skill is not set to always:true and does not request elevated or persistent platform privileges. It does not modify other skills or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install car-sales-invoice-ocr - After installation, invoke the skill by name or use
/car-sales-invoice-ocr - Provide required inputs per the skill's parameter spec and get structured output
