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. A global-install postinstall hook automatically installs an AI skill and copies it into assistant configuration directories. No credential theft or destructive behavior was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-09-29T10:57:45.978Z - **Finished:** 2026-09-29T10:58:34.161Z - **Download time:** 758 ms - **Static scan time:** 155 ms - **AI review time:** 47269 ms - **Total time:** 48183 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:** A global-install postinstall hook automatically installs an AI skill and copies it into assistant configuration directories. No credential theft or destructive behavior was confirmed. - **Trigger:** Global npm installation outside CI without the opt-out setting. - **Impact:** This changes AI-assistant skill configuration without an explicit follow-up user command. - **Evidence paths:** package.json, bin/postinstall.js, bin/run.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T10:58:34.161Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches the package command, which uses npx to add its skill globally and copies skill files to named assistant directories. - **Rationale:** The package performs a guarded but automatic global AI-agent extension setup during postinstall. This is a concrete lifecycle risk, not evidence of a confirmed malicious payload or exfiltration. - **Files touched:** skills/guanmetric ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** package.json defines a postinstall hook., The hook runs only for global non-CI installs, then invokes install-skill automatically., install-skill invokes npx with automatic confirmation to globally add this package skill., The command copies the package skill into CodeBuddy and WorkBuddy home configuration directories. - **Evidence against:** The hook skips local installs, CI, and an explicit opt-out environment setting. ## Affected versions and remediation This report applies to @guandata/guanmetric@0.1.16. - Review the evidence and your use of @guandata/guanmetric@0.1.16 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.
