AI Security Review

scanned 2d ago · by lpm-firewall-ai

The postinstall hook mutates user-level agent skill directories without an interactive consent step and can overwrite an existing same-named skill. The installed content is first-party, so this supports a warning for agent extension lifecycle risk rather than a malicious verdict.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

Installing the npm package runs its postinstall hook.

Impact

The installed skill can affect agent behavior, and a user’s existing scriptctl skill contents can be overwritten.

Mechanism

The hook copies the packaged scriptctl skill into the user’s Claude, agents, and Codex skill directories after removing each existing scriptctl folder.

AI rationale

Evidence

package.jsonscripts/install-skill.mjsskills/scriptctl/SKILL.md~/.claude/skills/scriptctl~/.agents/skills/scriptctl~/.codex/skills/scriptctl

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package postinstall runs the skill installer.
The installer targets Claude, agents, and Codex skill directories under the user’s home directory.
The installer loops through those targets and installs the package’s skill.
It recursively removes an existing same-named target before copying the packaged skill.
The copied skill is the package’s own scriptctl skill for screenplay CLI work.

Evidence against

The installed skill is first-party and describes screenplay work; inspected source did not establish credential theft or other active attack behavior.
The installer has environment-variable opt-outs.

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。
