Why this conclusion was reached

2/4 dimensions flagged
Block
Declared vs actual capability

2 undeclared or violating capabilities were inferred.

Review
Hidden execution and egress

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

Block
Attack chain and severe findings

The report includes 3 attack-chain steps and 1 severe findings.

Review
Dependencies and supply chain hygiene

Dependency information is incomplete, so supply-chain confidence stays limited.

What drove the risk score up

远程 SKILL.md 覆盖机制 +20

426 错误处理时执行 curl 下载远程 SKILL.md 并覆盖本地文件,无完整性验证

凭证通过 API 传输 +15

Suno/MVSEP API keys、PayPal 邮箱、API tokens 通过 update-agent-settings 端点传输

curl|bash 安装模式 +8

SETUP.md 展示 curl -fsSL URL | bash 安装方式,无签名验证

硬编码 API 密钥 +5

SKILL.md 包含硬编码的 Supabase REST API key

Most important evidence

High Supply Chain

远程 SKILL.md 覆盖机制存在供应链攻击风险

426 错误处理流程要求代理执行 curl 下载远程 SKILL.md 并覆盖本地文件。攻击者若控制 beatclaw.com 域名或中间人攻击,可植入恶意指令覆盖技能定义。skill-card.md 已声明此风险但无实际缓解措施。

SKILL.md:45
在覆盖前验证下载内容的 GPG 签名或 SHA256 哈希;仅在可信网络环境下执行更新。
Medium Credential Theft

API 密钥通过 update-agent-settings 端点传输

Suno API key、MVSEP API key 通过 update-agent-settings 端点传输到 beatclaw.com 平台。凭证理论上应仅用于调用外部 API,但传输路径和存储安全性未知。

SKILL.md:92
确认平台是否记录或存储这些密钥;考虑使用环境变量替代 API 密钥传输。
Medium Doc Mismatch

文档未声明 shell 写入权限

SKILL.md 声明为纯文档型技能,但 426 错误处理流程实际需要 shell:WRITE 权限来执行 curl 下载和文件覆盖操作,与声称的能力不符。

SKILL.md:43
在 SKILL.md 权限声明部分明确列出 shell:WRITE 和 filesystem:WRITE 权限。
Low Supply Chain

curl|bash 安装模式缺乏完整性验证

SETUP.md 展示的安装命令使用 curl -fsSL URL | bash 模式,无签名验证或哈希校验。

SETUP.md:6
提供安装脚本的 SHA256 哈希供验证。
Low Sensitive Access

硬编码 API 密钥暴露

SKILL.md 包含硬编码的 Supabase REST API key,可能被意外泄露。

SKILL.md:77
使用环境变量替代硬编码密钥。

Security positives

skill-card.md 主动声明了远程 SKILL.md 覆盖、凭证处理、人类确认等已知风险
文档明确要求生成前必须获得人类确认
要求明确禁止暴露 secrets
API 密钥传输到第三方平台(Suno/MVSEP)而非存储在本地,有合理业务解释
无发现代码执行、凭证收割、Base64 混淆等高危指标
