## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 1.8.9
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

LPM treats this as warn-only first-party agent extension lifecycle risk. npm installation automatically invokes an obfuscated initializer. It installs package-provided Agent skills and can remove peer skill entries in the Agent skills location.

## Security analysis

### Published attack-surface review

- **Summary:** npm installation automatically invokes an obfuscated initializer. It installs package-provided Agent skills and can remove peer skill entries in the Agent skills location.

- **Trigger:** Installing the package with lifecycle scripts enabled.

- **Impact:** It mutates the local Agent skill control surface without an explicit user command; the obfuscation makes the exact scope difficult to verify.

- **Evidence paths:** package.json, scripts/postinstall.cjs, dist/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T20:38:45.840Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Postinstall launches an obfuscated local initializer that copies skills and removes legacy entries.

- **Rationale:** This is a real automatic Agent-extension lifecycle mutation, but the inspected path is package-named and no exfiltration, remote payload execution, or self-dependency chain was found. Downgrade to warning under the lifecycle policy.

- **Files touched:** scripts/postinstall.cjs, dist/index.js, ~/.agents/skills/sino-bc-cli/, ~/.sino-bc-cli/config.json

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The install lifecycle automatically runs the CLI initializer., The initializer is heavily obfuscated, which prevents transparent inspection of its file operations., The bundled initializer removes peer entries while installing its named skill tree.

- **Evidence against:** The postinstall helper only launches a local bundled entry point and contains no network call., No self-dependency or remote payload loader was found in package.json., The observed target is a package-named Agent skill directory, not a general Agent configuration file.

## Affected versions and remediation

L2: * npm 安装后自动注册 Agent 技能
L3: * 使用 .cjs：scripts/package.json 为 "type": "module"，.js 无法使用 require
L4: * dist 不存在时（本地尚未 build）静默跳过，避免打断 npm install
...
L10: const { join } = require('path');
