Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.5.32 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The preinstall hook performs a Node version check, while the inspected agent configuration write is user-invoked and limited to missing project files. I classify that concrete agent configuration capability as warning-level risk; the inspected credential use targets the Hugging Face API. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-09T20:11:39.403Z - **Finished:** 2026-10-09T20:12:49.696Z - **Download time:** 2296 ms - **Static scan time:** 470 ms - **AI review time:** 67526 ms - **Total time:** 70293 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:** The explicit project init command can add an agent instruction file to a project. No automatic install-time agent configuration change or confirmed attack was identified. - **Trigger:** A user invokes the init command in a project. - **Impact:** The new AGENTS.md may influence later agent sessions in that project; source inspection did not establish harmful instructions or an attack. - **Evidence paths:** extensions/research-tools/project.ts - **Review source:** ai\_review - **Reviewed:** 2026-10-09T20:12:49.696Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command creates AGENTS.md only if it does not already exist, and creates session-log directories and a README when absent. - **Rationale:** The preinstall hook performs a Node version check, while the inspected agent configuration write is user-invoked and limited to missing project files. I classify that concrete agent configuration capability as warning-level risk; the inspected credential use targets the Hugging Face API. - **Files touched:** extensions/research-tools/project.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The preinstall hook only checks the Node.js version., The init command is explicitly registered and writes AGENTS.md only when it is absent, along with session-log folders., The executable loads the bundled CLI; its child-process helper launches the package’s bundled alpha CLI with inherited arguments and environment. - **Evidence against:** The project init command can create an AGENTS.md file in the current project, which can affect later agent behavior., Hugging Face requests use HF\_TOKEN or HUGGINGFACE\_HUB\_TOKEN as authorization headers for the Hugging Face API. ## Affected versions and remediation This report applies to @companion-ai/feynman@0.5.32. - Review the evidence and your use of @companion-ai/feynman@0.5.32 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.
