Impact · SKILL.md:44
What drove the risk score up
curl -fsSL https://taskfuel.ai/install.sh | sh 已声明但仍属高危模式
taskfuel connect 在后台运行且尝试打开浏览器
纯文档 skill,CLI 工具本身非恶意
功能描述与实际行为匹配
Most important evidence
远程脚本管道执行
SKILL.md:22 包含 curl -fsSL https://taskfuel.ai/install.sh | sh,这是经典的远程代码执行模式。虽然已声明但仍属高危行为。
SKILL.md:22 未声明的浏览器自动启动
taskfuel connect 命令会尝试自动打开浏览器进行账户授权,SKILL.md 未明确声明此行为。
SKILL.md:44 后台进程启动
taskfuel connect 在后台运行,agent 需要读取其输出并处理配对码,期间可能存在状态同步问题。
SKILL.md:40 allowed-tools 声明缺失
SKILL.md 和 _meta.json 均未声明 allowed-tools 字段,无法确认声明的权限边界。
SKILL.md:1 Declared capability vs actual capability
SKILL.md:22 curl/sh 命令 通过 taskfuel CLI 调用外部 API SKILL.md:44 taskfuel connect 尝试打开浏览器 SKILL.md:16 读取 TASKFUEL_BASE_URL Suspicious artifacts and egress
