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 install lifecycle hook or confirmed attack behavior. The scanner’s agent-path and credential-exfiltration hints are not supported by the inspected code: the cited agent helper classifies paths, and telemetry sends limited CLI usage metadata to the package’s Hub. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-18T13:20:07.435Z - **Finished:** 2026-10-18T13:20:41.085Z - **Download time:** 1542 ms - **Static scan time:** 3961 ms - **AI review time:** 28146 ms - **Total time:** 33650 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 in the inspected source. The flagged agent-path code classifies paths, while CLI telemetry sends limited usage metadata to the package’s Hub. - **Trigger:** Telemetry runs when a CLI command is invoked. - **Impact:** The inspected behavior does not establish credential theft, command-output disclosure, or agent configuration changes. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T13:20:41.085Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends the command name, client version, CI status, and operating system to its default Hub endpoint; an environment variable can disable this telemetry. - **Rationale:** Source inspection found no install lifecycle hook or confirmed attack behavior. The scanner’s agent-path and credential-exfiltration hints are not supported by the inspected code: the cited agent helper classifies paths, and telemetry sends limited CLI usage metadata to the package’s Hub. - **Files touched:** package.json, cli/dist/main.cjs - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com ### 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 declares no lifecycle scripts and includes the CLI as package content., The inspected agent-path helper only recognizes agent configuration directories for path classification; it does not modify agent settings., The CLI telemetry sends command, version, CI status, and operating system to the package’s default Hub endpoint; it does not include credentials or command output., Telemetry is emitted when a CLI command runs and can be disabled with MMI\_TELEMETRY=off. ## Affected versions and remediation This report applies to @mutmutco/claude-plugin@4.5.107. - Review the evidence and your use of @mutmutco/claude-plugin@4.5.107 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.
