AI Security Review

scanned 11d ago · by lpm-firewall-ai

The postinstall hook performs package-owned agent skill setup, which merits a warning under the extension lifecycle policy. The inspected source does not establish an unconsented broad agent control-surface takeover or another confirmed attack.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm installation, unless the installer is disabled by its environment-variable opt-outs.

Impact

The package can add or replace its own agent skill during installation; no broader control hijack was established.

Mechanism

The installer copies the bundled skill into per-user Claude, agents, and Codex skill subdirectories, replacing the existing scriptctl subdirectory.

AI rationale

Evidence

package.jsonscripts/install-skill.mjs~/.claude/skills/scriptctl~/.agents/skills/scriptctl~/.codex/skills/scriptctl

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook runs a script that installs the package's bundled skill into Claude, agents, and Codex skill directories.
The installer removes and replaces only the scriptctl skill subdirectory and provides environment-variable opt-outs.
The view server binds to loopback; the Gemini adapter uses its SDK with a caller-configurable base URL.

Evidence against

Inspected source shows first-party skill setup rather than broad agent configuration changes or a remote payload channel.
The flagged dynamic require loads the declared Google SDK, and the view server uses a loopback address.

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。
