Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 21 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 1.0.841 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 no concrete attack behavior. The credential request is part of worker authentication to the package’s default Gu API, and the install hook performs conditional PATH setup. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-17T17:18:45.139Z - **Finished:** 2026-10-17T17:20:47.165Z - **Download time:** 1524 ms - **Static scan time:** 4488 ms - **AI review time:** 116013 ms - **Total time:** 122026 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 surface was identified in the inspected source. The install hook conditionally updates PATH, while the reviewed runtime behavior serves the CLI’s documented Gu and local development functions. - **Trigger:** Package installation runs the postinstall PATH setup; other reviewed behavior requires using the CLI or REPL. - **Impact:** No concrete attack impact was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T17:20:47.165Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer adds npm’s global bin directory when it is absent from PATH. The login flow sends a worker key to the configured Gu API for authentication. - **Rationale:** Source inspection found no concrete attack behavior. The credential request is part of worker authentication to the package’s default Gu API, and the install hook performs conditional PATH setup. ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest runs a postinstall that adds npm’s global bin directory to a shell profile when needed., The REPL asks for a worker key or browser sign-in; key validation sends it to the default Gu API host for a read-only settings request., Project hooks run only after per-folder approval, and approval is an explicit command; Claude settings are read without being written., Project MCP servers are filtered by per-folder approval before use, and the CLI exposes explicit approval commands., The reviewed MongoDB, proxy, browser extension, and agent-stop helpers perform their stated operational tasks; no attack behavior was identified in them., Provider setup keeps API keys out of provider URLs. - **Evidence against:** The scanner flags credential redirection, but the inspected source uses the default Gu API for worker-key authentication and validation., The postinstall changes shell PATH only when npm’s global bin directory is missing from PATH. ## Affected versions and remediation This report applies to @tiens.nguyen/gu-cli@1.0.841. - Review the evidence and your use of @tiens.nguyen/gu-cli@1.0.841 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.
