Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## 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:** 1.8.22 - **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. Automatic installation attempts to register package-owned agent skills. Source validation and package-scoped destinations limit the behavior; no confirmed malicious attack was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-30T09:23:30.783Z - **Finished:** 2026-09-30T09:25:08.022Z - **Download time:** 760 ms - **Static scan time:** 286 ms - **AI review time:** 96191 ms - **Total time:** 97239 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:** Automatic installation attempts to register package-owned agent skills. Source validation and package-scoped destinations limit the behavior; no confirmed malicious attack was established. - **Trigger:** npm postinstall invokes /init --quiet. - **Impact:** When sources are available, installation adds or replaces this package's agent instructions. The missing source tree prevents the inspected registration path from reaching writes in this snapshot. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T09:25:08.022Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI locates skill sources and copies them into package-named agent skill directories, checking agent roots for conditional destinations. - **Rationale:** The inspected lifecycle attempts first-party package-owned agent extension setup, which the supplied policy classifies as warning-only. Source guards and package-scoped writes do not establish broad control hijacking or another concrete malicious chain. - **Files touched:** SKILL.md, .claude, skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The npm postinstall hook automatically invokes the CLI with /init --quiet., Registration copies package skill files into a directory named sino-bc-cli., Registration targets agent skill directories, including Claude, with agent-root existence guards., Registration requires a source skill tree before writing; that tree is absent from this snapshot. - **Evidence against:** Inspected registration writes are scoped to this package's skill directory., No concrete exfiltration or broad agent configuration overwrite was established. ## Affected versions and remediation This report applies to sino-bc-cli@1.8.22. - Review the evidence and your use of sino-bc-cli@1.8.22 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.
