## 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:** 1.8.5
- **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. Installing the package automatically invokes an obfuscated CLI initializer. The initializer is intended to install this package's agent skill into a user-level agent skills directory.

## Latest scan

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Installing the package automatically invokes an obfuscated CLI initializer. The initializer is intended to install this package's agent skill into a user-level agent skills directory.

- **Trigger:** npm postinstall

- **Impact:** It can influence an installed AI agent without an explicit setup command, but no broad control-surface overwrite or exfiltration was confirmed.

- **Evidence paths:** scripts/postinstall.cjs, dist/SKILL.md

- **Review source:** ai\_review

- **Reviewed:** 2026-09-09T11:02:05.726Z

### AI review details

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

- **Mechanism:** Automatic first-party agent extension registration

- **Rationale:** This is an automatic, obfuscated agent-extension installer, which warrants a warning. The available source does not establish a foreign or broad agent-control overwrite, remote payload execution, or data theft required for a malicious block.

- **Files touched:** scripts/postinstall.cjs, dist/index.js, dist/SKILL.md

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The install lifecycle automatically starts the bundled CLI with /init., The shipped agent skill instructs agents to use this CLI and avoid direct gateway requests., The distributed CLI is heavily obfuscated, preventing transparent verification of its initialization writes.

- **Evidence against:** The lifecycle launcher executes the package-local entrypoint with Node and supplies no remote command., The manifest has no dependency on another version of sino-bc-cli., The installed skill target is a package-named directory, indicating a first-party extension rather than a broad agent-config overwrite.

## Affected versions and remediation

- Review the evidence and your use of sino-bc-cli@1.8.5 before allowing it. Restrict the permissions described in this report.
