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 its initializer. The initializer installs a sino-bc-cli skill tree in the user's agent-skills directory and removes legacy same-vendor skill directories. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-12T22:45:52.765Z - **Finished:** 2026-09-12T22:46:29.544Z - **Download time:** 516 ms - **Static scan time:** 133 ms - **AI review time:** 36128 ms - **Total time:** 36779 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 invokes its initializer. The initializer installs a sino-bc-cli skill tree in the user's agent-skills directory and removes legacy same-vendor skill directories. - **Trigger:** npm postinstall during package installation. - **Impact:** It changes local AI-agent skill configuration without an explicit CLI command. - **Evidence paths:** package.json, scripts/postinstall.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T22:46:29.544Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic first-party agent extension registration. - **Rationale:** This is an automatic lifecycle mutation of an AI-agent extension surface, but it is confined to the package's own named skill tree and legacy same-vendor directories. The opaque bundle warrants a warning rather than a block under the stated policy. - **Files touched:** ~/.agents/skills/sino-bc-cli/, ~/.agents/skills/sino-bc-shared/, ~/.agents/skills/sino-bc-\/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The postinstall hook automatically runs the CLI initialization command., The shipped CLI is deliberately obfuscated and its initialization code writes this package's skill tree under the user's agent-skills directory. - **Evidence against:** The hook launches only the packaged CLI entry point with fixed arguments., No self-dependency, remote payload download, credential harvesting, or unrelated network endpoint was found. ## Affected versions and remediation This report applies to sino-bc-cli@1.8.7. - Review the evidence and your use of sino-bc-cli@1.8.7 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.
