AI Security Review

scanned 11d ago · by lpm-firewall-ai

The postinstall hook performs guarded, package-owned skill setup in three user-level agent skill directories, replacing only the scriptctl subdirectory. This is a lifecycle extension risk, but the inspected source does not establish malicious behavior or justify a publish block.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm installation runs the postinstall hook unless the installer opt-out environment variables are set.

Impact

This adds or replaces a package-specific agent skill and is a guarded first-party extension setup; inspected source does not establish broader agent control or a concrete attack.

Mechanism

The installer recursively removes each existing scriptctl skill directory and copies the bundled skill into its place.

AI rationale

Evidence

package.jsonscripts/install-skill.mjs

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook runs a script that copies the package-owned scriptctl skill into three user-level agent skill directories.
The installer removes the existing scriptctl skill directory before copying its replacement; environment variables can opt out.
The package also exposes an explicit update command that runs npm to install a release of this same package.
The inspected review-agent code sends JSON POST requests; the excerpt does not establish credential theft or an unrelated recipient.

Evidence against

The skill installer limits its removal to the scriptctl subdirectory and copies the bundled skill there.
No inspected source establishes a hidden payload, credential exfiltration, or an unconsented broad agent configuration write.

2// postinstall: 把打包进 npm 包的 scriptctl skill 装到用户根目录下的三处 skill 目录

3// （Claude Code / agents / codex），并把「本次安装对应的 scriptctl 版本号」戳进每份

4// SKILL.md 的 frontmatter + 一个 .scriptctl-version 标记文件里。

5//

6// 设计要点：

7// - 永不让安装失败：全程 try/catch，任何异常只打印警告并以 0 退出（skill 装不上不该

8// 拖垮 `npm i -g scriptctl` 本身）。

9// - 开发态跳过：源码检出（存在 src/）不是「已发布的包」，跳过，免得 dev `pnpm install`

10// 覆盖你本地手改的 skill。

11// - 可关闭：SCRIPTCTL_SKIP_SKILL_INSTALL=1 或 SCRIPTCTL_SKILL_INSTALL=0。
