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 a Node-version install guard, user-triggered project setup and AlphaXiv authentication, and package-aligned runtime telemetry. Although failed commands may send up to 4 KB of Pi stderr, the telemetry has an opt-out and does not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-23T14:24:50.820Z - **Finished:** 2026-10-23T14:27:08.627Z - **Download time:** 513 ms - **Static scan time:** 518 ms - **AI review time:** 136774 ms - **Total time:** 137807 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 malicious attack behavior was identified in the inspected source. The automatic install action checks the Node version; observed authentication and project setup are user-triggered. - **Trigger:** The version check runs during npm installation. AlphaXiv login and project scaffolding require an explicit command or setup confirmation. - **Impact:** No confirmed attack impact was established; the observed telemetry is limited to runtime reporting and can be disabled. - **Review source:** ai\_review - **Reviewed:** 2026-10-23T14:27:08.627Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** No unrelated credential transfer or unconsented agent-control change was found. Runtime telemetry sends command data and may include bounded Pi stderr after a failed command, with an opt-out notice. - **Rationale:** Source inspection found a Node-version install guard, user-triggered project setup and AlphaXiv authentication, and package-aligned runtime telemetry. Although failed commands may send up to 4 KB of Pi stderr, the telemetry has an opt-out and does not establish malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package’s only install hook runs a Node version check; the script compares the installed version with the minimum and exits when it is too old., The flagged project-file write belongs to the explicit \`/init\` command. It creates \`AGENTS.md\` only when that file is absent and preserves an existing one., AlphaXiv login is triggered by an explicit command or setup confirmation and uses the AlphaXiv authentication issuer., The inspected dependencies provide prompt UI, AlphaXiv authentication, and XML parsing functionality through their declared entrypoints., Runtime telemetry reports command metadata and may include up to 4 KB of Pi stderr after a failed command. The package displays an opt-out notice; no unrelated credential recipient or agent-control mutation was found. - **Evidence against:** Telemetry is enabled by default and may send Pi stderr from failed commands to the configured or default PostHog host. ## Affected versions and remediation This report applies to @companion-ai/feynman@0.5.56. - Review the evidence and your use of @companion-ai/feynman@0.5.56 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.
