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 lifecycle hook or concrete attack behavior. The default-on outbound request is limited to CLI usage fields and goes to the package’s configured MMI hub. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-15T23:40:45.927Z - **Finished:** 2026-10-15T23:44:46.343Z - **Download time:** 1294 ms - **Static scan time:** 5448 ms - **AI review time:** 233673 ms - **Total time:** 240416 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 CLI sends bounded usage telemetry to its configured MMI hub when a command runs. - **Trigger:** A user invokes a CLI command; telemetry can be disabled with MMI\_TELEMETRY=off. - **Impact:** The inspected behavior does not establish credential theft, project-data collection, or agent configuration changes. - **Review source:** ai\_review - **Reviewed:** 2026-10-15T23:44:46.343Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The telemetry request contains the command name, version, CI status, and operating system. The cited agent-directory logic only classifies Git paths. - **Rationale:** Source inspection found no lifecycle hook or concrete attack behavior. The default-on outbound request is limited to CLI usage fields and goes to the package’s configured MMI hub. - **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com/telemetry/cli-call ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json contains no lifecycle hooks or dependency declarations; it packages the plugin, skills, bin, and CLI files., The cited agent-directory paths are used as Git path filters; this code does not modify agent configuration., CLI telemetry sends only the command name, package version, CI status, and operating system to the configured hub., Telemetry is called from the CLI command pre-action hook and can be disabled with MMI\_TELEMETRY=off., The package’s only observed outbound telemetry destination defaults to its MMI hub. - **Evidence against:** Telemetry is enabled by default, but the inspected payload contains no credentials, environment contents, or project records. ## Affected versions and remediation This report applies to @mutmutco/claude-plugin@4.5.156. - Review the evidence and your use of @mutmutco/claude-plugin@4.5.156 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.
