Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 0.5.57 - **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. Static inspection found no malicious install hook or credential theft. The default-on telemetry path can transmit failed tool-result text, creating a conditional privacy risk that supports a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-24T05:08:09.112Z - **Finished:** 2026-10-24T05:09:18.753Z - **Download time:** 515 ms - **Static scan time:** 482 ms - **AI review time:** 68643 ms - **Total time:** 69641 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:** Telemetry can send text from failed tool results to Feynman's PostHog collector. This creates a conditional privacy exposure if an error contains sensitive text. - **Trigger:** A CLI-launched Pi session runs a tool that reports an error while telemetry is enabled. - **Impact:** Sensitive text included in a tool error may be disclosed to the telemetry collector. - **Evidence paths:** dist/cli.js, dist/pi/runtime.js, dist/telemetry/posthog.js, extensions/research-tools/telemetry.ts - **Review source:** ai\_review - **Reviewed:** 2026-10-24T05:09:18.753Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The extension extracts text content from the failed result and adds it to a captured telemetry event. - **Rationale:** Static inspection found no malicious install hook or credential theft. The default-on telemetry path can transmit failed tool-result text, creating a conditional privacy risk that supports a warning rather than a block. - **Files touched:** dist/cli.js, dist/pi/runtime.js, dist/telemetry/posthog.js, extensions/research-tools.ts, extensions/research-tools/telemetry.ts - **Network endpoints:** https://us.i.posthog.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The preinstall hook runs a Node version check that exits on unsupported versions., The explicit init command creates AGENTS.md only when that file is absent., CLI startup initializes telemetry and passes its settings to the Pi child; the first-run notice describes error telemetry generally., Telemetry can be disabled through environment settings, and its default collector is Feynman's PostHog host., When a Pi tool reports an error, the extension extracts text from its result and includes it in a telemetry event sent to the configured collector. ## Affected versions and remediation This report applies to @companion-ai/feynman@0.5.57. - Review the evidence and your use of @companion-ai/feynman@0.5.57 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.
