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. No confirmed malicious attack surface was established. The observed macOS persistence is an explicit user-command feature of this CLI, not an npm lifecycle action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-04T19:49:13.729Z - **Finished:** 2026-09-04T19:50:23.247Z - **Download time:** 761 ms - **Static scan time:** 4456 ms - **AI review time:** 64299 ms - **Total time:** 69518 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 confirmed malicious attack surface was established. The observed macOS persistence is an explicit user-command feature of this CLI, not an npm lifecycle action. - **Trigger:** A user runs waterbrother listen install. - **Impact:** The explicitly requested CLI feature persists the listen service for that user. - **Review source:** ai\_review - **Reviewed:** 2026-09-04T19:50:23.247Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Creates a package-owned macOS launch agent for the listen daemon. - **Rationale:** Source inspection found no automatic lifecycle execution or credential exfiltration. The flagged persistence is explicitly user-invoked and package-owned, while the deep-scan and shell findings are aligned with the stated coding and dependency-scanning CLI functionality. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a CLI but has no preinstall, install, or postinstall hook., The launch-agent installation path is reached only after the user explicitly invokes the listen install command., The persistence code creates a named Waterbrother macOS launch agent that runs this package's listen daemon., The flagged deep scanner is an in-memory package-analysis feature and states that it does not execute scanned package code., The coding-agent shell capability is guarded by an approval-required tool list. - **Evidence against:** No credential harvesting or transmission to an unrelated endpoint was found., No automatic install-time execution, self-dependency, obfuscation, or foreign AI-agent configuration mutation was found., Network code is consistent with configured model providers and opt-in CLI features. ## Affected versions and remediation This report applies to @tritard/waterbrother@0.17.3. - Review the evidence and your use of @tritard/waterbrother@0.17.3 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.
