Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 13 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.5.25 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 preinstall hook performs a Node version check, while project configuration writes require explicit init invocation and preserve existing AGENTS.md. The flagged child-process and credential behavior is consistent with launching the bundled CLI and accessing Hugging Face; no malicious attack surface was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-09T20:11:19.956Z - **Finished:** 2026-10-09T20:11:55.767Z - **Download time:** 761 ms - **Static scan time:** 483 ms - **AI review time:** 34566 ms - **Total time:** 35811 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 lifecycle, CLI, project setup, or Hugging Face request paths. - **Trigger:** Installation runs the Node version check; the project file setup runs only when a user invokes the init command. - **Impact:** No malicious effect was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T20:11:55.767Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The init command preserves an existing AGENTS.md, and the inspected credentialed requests target Hugging Face. - **Rationale:** Source inspection shows the preinstall hook performs a Node version check, while project configuration writes require explicit init invocation and preserve existing AGENTS.md. The flagged child-process and credential behavior is consistent with launching the bundled CLI and accessing Hugging Face; no malicious attack surface was established. - **Network endpoints:** https://huggingface.co/api, https://huggingface.co ### 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 preinstall runs a Node version check; the check exits only when the Node version is unsupported., The project init command creates AGENTS.md only when it does not already exist., The CLI checks for its Pi peer dependencies, then loads the bundled CLI entrypoint., The bundled CLI loads a cwd .env file and launches the bundled alpha CLI with the current environment and working directory., Hugging Face requests use a fixed Hugging Face endpoint and send the Hugging Face token there when configured. ## Affected versions and remediation This report applies to @companion-ai/feynman@0.5.25. - Review the evidence and your use of @companion-ai/feynman@0.5.25 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.
