Skill Trust Decision

tongcheng-travel-assistant

同程旅行助手功能正常，凭证硬编码用于API调用但未外泄用户数据，第三方依赖缺乏版本锁定存在供应链风险。

Why this conclusion was reached

0/4 dimensions flagged
Pass
Declared vs actual capability

Declared resources and inferred behavior are broadly aligned.

Review
Hidden execution and egress

1 lower-risk artifacts were extracted and still need context.

Pass
Attack chain and severe findings

There is no explicit malicious chain in the report.

Pass
Dependencies and supply chain hygiene

Dependencies are present but no obvious high-risk issue stands out.

What drove the risk score up

凭证硬编码 +10

PROXY_TOKEN硬编码在源码中，但用于合法API调用场景

第三方依赖无版本锁定 +8

无requirements.txt，urllib为标准库但整体缺少依赖管理

外部URL数据流向声明不透明 +4

SKILL.md声明'代理不存储数据'但无法验证

Most important evidence

Low Supply Chain

第三方依赖无版本锁定

代码使用标准库urllib但无requirements.txt，缺少依赖版本管理，无法保证构建一致性

tongcheng_travel.py:1
建议添加requirements.txt明确依赖版本
Low Doc Mismatch

凭证声明与实际不符

SKILL.md声明'自动配置，无需手动设置'但PROXY_TOKEN硬编码在源码中，虽为合法API Token但应透明声明

tongcheng_travel.py:13
建议在文档中说明凭证为内置或提供环境变量覆盖机制
Low Data Exfil

外部代理数据政策不透明

SKILL.md声明'代理不存储用户数据'但无法验证，用户查询数据发送到腾讯云SCF服务器

tongcheng_travel.py:12
建议提供代理服务的数据处理隐私政策链接
