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 two assistant configuration locations. No credential theft, data exfiltration, or destructive behavior was identified in the inspected scripts. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-29T14:35:46.377Z - **Finished:** 2026-09-29T14:38:10.872Z - **Download time:** 1272 ms - **Static scan time:** 154 ms - **AI review time:** 143068 ms - **Total time:** 144495 ms The recorded confidence comes from the underlying analysis.

No credential theft, data exfiltration, or destructive behavior was identified in the inspected scripts. - **Trigger:** A global npm installation or upgrade outside CI, without the opt-out flag. - **Impact:** This is a guarded automatic AI-agent extension installation affecting user home configuration, but no confirmed active attack surface was established. - **Evidence paths:** bin/postinstall.js, bin/run.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T14:38:10.872Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook starts the package launcher with install-skill; that path non-interactively calls the skills installer and then copies the bundled skill to CodeBuddy and WorkBuddy directories. - **Rationale:** The automatic postinstall mutation of AI-assistant skill locations is a concrete guarded extension lifecycle risk. Its constraints and absence of a demonstrated harmful payload support a warning rather than a block. - **Files touched:** .codebuddy/skills/guanmetric, .workbuddy/skills/guanmetric ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package registers a postinstall hook that launches bin/postinstall.js., The hook runs only for global, non-CI installs unless an opt-out environment flag is set, then invokes install-skill., The install-skill path non-interactively invokes npx skills add with global-install flags., After that command succeeds, it copies the package skill into CodeBuddy and WorkBuddy configuration directories. - **Evidence against:** The lifecycle hook skips local installs and CI, and supports an explicit opt-out., No source inspected shows credential collection, data transmission, destructive actions, or remote payload execution. ## Affected versions and remediation This report applies to @guandata/guanmetric@0.1.17. - Review the evidence and your use of @guandata/guanmetric@0.1.17 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.
