AI Security Review

scanned 6d ago · by lpm-firewall-ai

Source confirms an automatic postinstall that installs a first-party skill into user-level agent directories without an affirmative prompt. Its scope and inspected content support a warning for extension lifecycle risk, but do not establish a broader control hijack or a concrete attack.

Static reason

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

Trigger

Installing the package with npm, which runs its postinstall hook.

Impact

Agent environments receive the package’s skill instructions automatically. The inspected source does not establish broader agent configuration changes or credential disclosure.

Mechanism

The hook copies the package’s scriptctl skill into three agent skill roots, replacing any existing scriptctl subdirectory; environment variables can opt out.

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 manifest runs the skill installer automatically through its postinstall hook.
The installer targets the scriptctl skill directory under the Claude, agents, and Codex skill roots.
For each target, the installer removes that scriptctl directory and copies in this package’s own skill files.
The installer has environment-variable opt-outs, but no affirmative consent prompt.
The installed guide describes using scriptctl with local screenplay files.

Evidence against

The installer’s deletion is scoped to the scriptctl child directory, rather than the surrounding skill roots.
The inspected skill guide describes a package-aligned local CLI workflow.

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

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。
