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. The package’s install hook sets up its own launchers and binaries, consistent with its stated purpose. However, TUI startup triggers an undisclosed, daily background request for the latest package version, so this is suspicious runtime telemetry. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-31T05:22:14.285Z - **Finished:** 2026-10-31T05:22:52.072Z - **Download time:** 1535 ms - **Static scan time:** 325 ms - **AI review time:** 35926 ms - **Total time:** 37787 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:** Undisclosed runtime update check contacts the npm registry for the package’s latest version. - **Trigger:** Opening the TUI, at most once per day. - **Impact:** Exposes a registry request associated with TUI use; no collection of credentials or machine details was identified. - **Evidence paths:** resources/scripts/rakumux.sh, resources/scripts/shell/gwr\_binary.sh, resources/scripts/shell/gwr/check-updates.sh, README.md - **Review source:** ai\_review - **Reviewed:** 2026-10-31T05:22:52.072Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A background script runs npm view rakumux version and records a timestamp in the user’s cache directory. - **Rationale:** The package’s install hook sets up its own launchers and binaries, consistent with its stated purpose. However, TUI startup triggers an undisclosed, daily background request for the latest package version, so this is suspicious runtime telemetry. - **Files touched:** ${HOME}/.cache/rakumux/last\_update\_check ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Opening the TUI starts a silent background update check; subcommands skip it., The check runs at most once per day and stores its timestamp under ~/.cache/rakumux/last\_update\_check., The update check queries npm for the latest rakumux version; this runtime network activity is not disclosed in the README. - **Evidence against:** The postinstall hook sets up the package’s own scripts and platform binaries in dist/., The package describes itself as a terminal session manager and documents its launcher commands., The inspected update check requests a package version and does not show collection of credentials or machine details. ## Affected versions and remediation This report applies to rakumux@0.1.37. - Review the evidence and your use of rakumux@0.1.37 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.
