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 runs its initialization command. That command installs package skills into an agent directory and initializes local configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-09T10:02:30.182Z - **Finished:** 2026-09-09T10:03:34.440Z - **Download time:** 507 ms - **Static scan time:** 186 ms - **AI review time:** 63564 ms - **Total time:** 64258 ms 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 runs its initialization command. That command installs package skills into an agent directory and initializes local configuration. - **Trigger:** npm installation that permits lifecycle scripts - **Impact:** It can change the local agent extension surface without an explicit user command. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-09T10:03:34.440Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall launches an opaque CLI agent-skill initializer. - **Rationale:** This is an automatic first-party agent extension setup with opaque implementation, so it warrants a warning. The inspected source does not establish concrete malware behavior. - **Files touched:** scripts/postinstall.cjs, dist/index.js, ~/.agents/skills/sino-bc-cli/, ~/.sino-bc-cli/config.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for warning:** The package installs an automatic postinstall hook., The hook launches the bundled CLI with /init and --quiet during installation., The opaque bundled CLI invokes installSkill and also initializes configuration, creating an unattended agent-extension setup path. - **Evidence against:** The postinstall script only launches a local bundled file; it contains no network call., There is no runtime dependency on sino-bc-cli itself., Static inspection found no credential harvesting, remote payload download, or arbitrary code evaluation. ## Affected versions and remediation This report applies to sino-bc-cli@1.8.4. - Review the evidence and your use of sino-bc-cli@1.8.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
