AI Security Review

scanned 11d ago · by lpm-firewall-ai

The automatic postinstall skill installation creates a concrete first-party agent extension lifecycle risk, so this warrants a warning. The inspected source does not support a publish block for an unconsented foreign or broad agent-control mutation.

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

Installing the npm package runs its postinstall hook, unless an environment-variable opt-out is set.

Impact

An existing scriptctl skill in those locations can be replaced, changing instructions available to the corresponding agent.

Mechanism

The installer targets the scriptctl subdirectory under .claude/skills, .agents/skills, and .codex/skills, removes each target recursively, then copies the bundled skill there.

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 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/install-skill.mjs during postinstall.
The script removes and replaces the package-owned scriptctl skill under three user-level agent skill directories; environment-variable opt-outs are available.
This establishes automatic first-party agent skill setup, but the inspected code does not establish a broader agent-control attack.

Evidence against

The Gemini SDK is loaded when the video route is exercised, rather than as install-time behavior.
The view server binds to 127.0.0.1 and is started by the view command.

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。
