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. The install hook only stages the package's scripts and binaries in its own directory, and the inspected scripts reveal no credential collection or unrelated network contact. The only observed network activity is a TUI update-version query; native executable internals could not be resolved. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-31T03:09:44.132Z - **Finished:** 2026-10-31T03:10:20.069Z - **Download time:** 1028 ms - **Static scan time:** 303 ms - **AI review time:** 34605 ms - **Total time:** 35937 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 identified. The install hook stages the package's own assets; the TUI checks for updates, and an optional shell hook records local session history. - **Trigger:** npm postinstall; the update check runs when the TUI starts; the history hook acts when a user sources it in an interactive Rakumux session. - **Impact:** No harmful install-time or default account action was found in the reviewed source. Native executable behavior remains unresolved. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T03:10:20.069Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies scripts and binaries into the package's dist directory. The update check queries npm for the Rakumux version. The shell hook appends session commands to a local history file. - **Rationale:** The install hook only stages the package's scripts and binaries in its own directory, and the inspected scripts reveal no credential collection or unrelated network contact. The only observed network activity is a TUI update-version query; native executable internals could not be resolved. - **Files touched:** dist/, ${RAKUMUX\_HOME:-$HOME/.rakumux}/history/\.log ### Review decision - **Verdict:** Clean - **Confidence:** 78.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook sets up Rakumux by copying its scripts and platform binaries into the package's own dist directory., The launcher runs a daily update check only for the TUI; the check queries npm for Rakumux's version., The optional shell hook is documented to record commands locally inside a Rakumux session. - **Evidence against:** The package ships native executables whose behavior could not be resolved from the available analysis; the package describes them as its terminal, daemon, API, and MCP components. ## Affected versions and remediation This report applies to rakumux@0.1.36. - Review the evidence and your use of rakumux@0.1.36 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.
