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 shows the install hook performs a Node version check, while the flagged agent configuration write is limited to an explicit init command and preserves an existing AGENTS.md. The token use inspected is directed to the Hugging Face API; no concrete attack surface was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-09T20:10:40.874Z - **Finished:** 2026-10-09T20:11:08.426Z - **Download time:** 509 ms - **Static scan time:** 456 ms - **AI review time:** 26586 ms - **Total time:** 27552 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 preinstall hook checks the Node version, and the project setup behavior is an explicit command that creates limited project files. - **Trigger:** Package installation invokes preinstall; the project setup behavior runs when a user invokes the init command. - **Impact:** No malicious effect was identified. The inspected Hugging Face token use sends credentials to the Hugging Face API. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T20:11:08.426Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook checks the installed Node version. The init command creates notes directories and adds AGENTS.md only if absent. - **Rationale:** Source inspection shows the install hook performs a Node version check, while the flagged agent configuration write is limited to an explicit init command and preserves an existing AGENTS.md. The token use inspected is directed to the Hugging Face API; no concrete attack surface was established. - **Files touched:** AGENTS.md, notes/, notes/session-logs/README.md - **Network endpoints:** https://huggingface.co/api ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The preinstall hook runs a Node version check, and the CLI entrypoint also checks the Node version before loading the CLI., The flagged project configuration command is explicitly invoked and creates AGENTS.md only when it does not already exist., The CLI loads a working-directory .env file; no malicious use of its contents was identified in the inspected excerpt., The Hugging Face tool sends optional Hugging Face tokens as authorization headers on its API requests. ## Affected versions and remediation This report applies to @companion-ai/feynman@0.5.10. - Review the evidence and your use of @companion-ai/feynman@0.5.10 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.
