Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found a conditional PATH update in postinstall and package-aligned CLI, provider validation, proxy, and setup behavior. No concrete attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-09T05:19:16.534Z - **Finished:** 2026-10-09T05:19:46.960Z - **Download time:** 517 ms - **Static scan time:** 2739 ms - **AI review time:** 27169 ms - **Total time:** 30426 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:** No attack was identified. The install hook conditionally adds the global npm bin directory to the user's shell profile, and the inspected runtime source supports the package's CLI and local model workflow. - **Trigger:** npm installation triggers the postinstall PATH setup; the worker runs when invoked through its CLI entrypoint. - **Impact:** The inspected behavior enables CLI access and intended model connections; no concrete malicious effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:19:46.960Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall adds a marked PATH entry for the global npm bin directory. Proxy routing is gated by configured model endpoint checks, and provider setup rejects metadata and link-local destinations. - **Rationale:** Source inspection found a conditional PATH update in postinstall and package-aligned CLI, provider validation, proxy, and setup behavior. No concrete attack behavior was established. ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall runs a PATH setup script, which conditionally adds the global npm bin directory to the user's shell profile., Provider URL validation rejects metadata and link-local addresses., Proxy routing applies only when the request passes configured proxy checks., The client expert setup probes the machine and checks whether setup is available., The CLI entrypoint starts the worker polling loop. ## Affected versions and remediation This report applies to @tiens.nguyen/gu-cli@1.0.704. - Review the evidence and your use of @tiens.nguyen/gu-cli@1.0.704 before allowing it.
