The postinstall automatically replaces the package's own skill directory in user-level agent locations, creating an agent extension lifecycle risk. Its limited destination scope and opt-out support do not establish a publish-blockable attack.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Installing the package with lifecycle scripts enabled, unless opted out.

Impact

The package can replace its own installed skill files in those locations.

Mechanism

The script removes and recopies the scriptctl skill subdirectory under three user-level skill roots.

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 89.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/install-skill.mjs automatically during postinstall.
The installer targets .claude/skills, .agents/skills, and .codex/skills.
For each target, it recursively removes and recopies only the scriptctl subdirectory.
The installer checks opt-out environment variables before proceeding.

Evidence against

The install operation is limited to the package-named skill directory; no broader agent configuration write or remote payload execution was identified.

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。
