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 npm install lifecycle hook or concrete attack behavior. The flagged agent configuration changes are part of explicit CLI integration setup, so the package is clean. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-11T19:01:29.410Z - **Finished:** 2026-10-11T19:02:05.433Z - **Download time:** 779 ms - **Static scan time:** 481 ms - **AI review time:** 34762 ms - **Total time:** 36023 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 was identified. The package configures its agent integrations through CLI actions and uses managed local settings and files. - **Trigger:** Running an explicit PennyRouter install, update, or launch command. - **Impact:** These actions enable the selected PennyRouter integration; inspected source did not establish unauthorized control-surface mutation or credential theft. - **Review source:** ai\_review - **Reviewed:** 2026-10-11T19:02:05.433Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI configures harness settings and writes managed runtime or statusline files; CodeGPT setup is manual. - **Rationale:** Source inspection found no npm install lifecycle hook or concrete attack behavior. The flagged agent configuration changes are part of explicit CLI integration setup, so the package is clean. ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes a command-line entry point; its scripts are start and check, with no install lifecycle hook., Agent configuration writes are reached through explicit install, update, or launch commands., The statusline helper preserves an existing user command when wrapping it and writes the managed setting to the supplied configuration object., CodeGPT setup presents manual instructions and does not edit JetBrains settings., MCP registry behavior is implemented as a config transformation; thread-session paths locate local session data. ## Affected versions and remediation This report applies to pennyrouter@0.2.33. - Review the evidence and your use of pennyrouter@0.2.33 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.
