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 hook or agent-configuration mutation at the flagged location. The reported credential and command-output concerns are not supported by the inspected source; the observed telemetry contains only basic CLI usage metadata and goes to the product-configured hub. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-18T13:27:56.820Z - **Finished:** 2026-10-18T13:28:37.932Z - **Download time:** 1531 ms - **Static scan time:** 4011 ms - **AI review time:** 35569 ms - **Total time:** 41112 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 has default-on call telemetry, but the inspected code limits its payload to command and basic runtime metadata. - **Trigger:** A CLI command invokes the telemetry function. - **Impact:** The inspected behavior reports basic CLI usage and does not expose credentials or establish an attack surface. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T13:28:37.932Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The function posts command, version, CI status, and operating system to the configured MMI hub; MMI\_TELEMETRY=off disables the send. - **Rationale:** Source inspection found no install hook or agent-configuration mutation at the flagged location. The reported credential and command-output concerns are not supported by the inspected source; the observed telemetry contains only basic CLI usage metadata and goes to the product-configured 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:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines no lifecycle scripts and publishes the CLI and plugin files., The flagged agent-path code classifies Claude, Cursor, Codex, and agent directories for Git change filtering; it does not mutate agent configuration., CLI telemetry sends only the command, version, CI status, and operating system to the configured MMI hub; the code supports disabling it with MMI\_TELEMETRY=off. - **Evidence against:** The CLI sends telemetry by default to the configured hub, whose built-in default is an AWS endpoint. ## Affected versions and remediation This report applies to @mutmutco/claude-plugin@4.5.128. - Review the evidence and your use of @mutmutco/claude-plugin@4.5.128 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.
