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. The scanner findings are explained by a vendored runtime archive and a research-agent CLI. Direct inspection found a benign preinstall check and user-invoked setup, not a concrete malicious chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-08-27T02:09:54.332Z - **Finished:** 2026-08-27T02:12:30.269Z - **Download time:** 6386 ms - **Static scan time:** 16156 ms - **AI review time:** 133394 ms - **Total time:** 155937 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 confirmed malicious attack surface was established. The package performs runtime setup only after its CLI is invoked. - **Trigger:** Installing runs the Node version checker; running feynman loads its bundled runtime and patches. - **Impact:** No source-backed credential theft, unconsented network exfiltration, destructive action, or foreign agent-control mutation was found. - **Evidence paths:** package.json, scripts/check-node-version.mjs, bin/feynman.js, scripts/patch-embedded-pi.mjs, scripts/install/install-skills.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-27T02:12:30.269Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local version validation and user-invoked runtime setup. - **Rationale:** The scanner findings are explained by a vendored runtime archive and a research-agent CLI. Direct inspection found a benign preinstall check and user-invoked setup, not a concrete malicious chain. - **Files touched:** scripts/check-node-version.mjs, bin/feynman.js, scripts/patch-embedded-pi.mjs, .feynman/runtime-workspace.tgz ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Installation runs a local Node version check., The command launcher dynamically imports bundled runtime code and applies Pi runtime patches when the user runs the CLI., The package includes a compressed vendored runtime workspace. - **Evidence against:** The preinstall source only checks the running Node version and prints guidance., No install-time download, shell execution, credential collection, or foreign agent configuration write was found., The skill installer downloads and writes files only when explicitly run by the user. ## Affected versions and remediation This report applies to @companion-ai/feynman@0.3.47. - Review the evidence and your use of @companion-ai/feynman@0.3.47 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.
