AI Security Review

scanned 1d ago · by lpm-firewall-ai

The automatic postinstall mutation of user-level agent skill directories warrants a warning for agent extension lifecycle risk. The inspected source supports this behavior but does not establish a concrete attack that justifies blocking publication.

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 unless an environment opt-out is set.

Impact

The package adds or replaces instructions that agents may use in later sessions.

Mechanism

The installer removes any existing scriptctl skill directory under three agent roots and copies in the package's skill.

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 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/install-skill.mjs from its postinstall hook.
The installer targets the user's .claude, .agents, and .codex skill directories.
For each target, the installer removes the existing scriptctl directory and copies in the package's skill.
The installed skill directs agents to use scriptctl commands.
The installer provides environment-variable opt-outs.

Evidence against

The setup is limited to a skill named scriptctl, and the installer skips source checkouts.
The inspected setup source does not establish credential theft, destructive behavior, or remote code execution.

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。
