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 guarded PATH setup hook and application-aligned CLI process and network behavior. No concrete malicious chain or credential exfiltration was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-09T05:20:32.226Z - **Finished:** 2026-10-09T05:21:04.612Z - **Download time:** 756 ms - **Static scan time:** 3755 ms - **AI review time:** 27874 ms - **Total time:** 32386 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 malicious attack surface was identified. The postinstall helper conditionally adds an idempotent PATH block to the user’s shell startup file. - **Trigger:** Package installation invokes the postinstall helper; other process and network behavior is activated through CLI features. - **Impact:** The startup-file change makes the CLI easier to invoke; inspected behavior does not establish covert access, exfiltration, or agent-control mutation. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:21:04.612Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper skips Windows and CI and writes a PATH block to the selected shell startup file. The inspected API, worker, and proxy code supports the package’s stated CLI functions. - **Rationale:** Source inspection found a guarded PATH setup hook and application-aligned CLI process and network behavior. No concrete malicious chain or credential exfiltration was established. - **Files touched:** install-path.mjs ### 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 helper; it skips Windows and CI, then adds an idempotent block to a shell startup file., The CLI uses process and network APIs as part of its worker and local API features; inspected code did not establish covert execution or credential exfiltration., The local API installer and proxy routing are explicit application features; proxy routing follows configured model endpoints. - **Evidence against:** The postinstall behavior is limited to making the installed CLI available on PATH; no foreign AI-agent control surface is modified., The flagged process and network behavior is consistent with the package’s CLI, worker, and local API functions. ## Affected versions and remediation This report applies to @tiens.nguyen/gu-cli@1.0.731. - Review the evidence and your use of @tiens.nguyen/gu-cli@1.0.731 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.
