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 agent-directed guidance creates a real but conditional risk of feedback submission without user request. The submission path uses the configured portal and the tool describes excluding project contents and secrets, so the inspected behavior supports a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-16T02:45:08.311Z - **Finished:** 2026-10-16T02:46:19.744Z - **Download time:** 751 ms - **Static scan time:** 284 ms - **AI review time:** 70398 ms - **Total time:** 71433 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:** Bundled guidance urges the connected agent to submit feedback without a user request. If followed, the feedback tool sends its supplied title and detail to the configured portal. - **Trigger:** The guidance is provided to the agent, which may then invoke the feedback tool. - **Impact:** Feedback may be submitted without the user asking for it; source does not establish automatic collection of project content or secrets. - **Evidence paths:** dist/feedback.js, dist/index.js, dist/portalClient.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T02:46:19.744Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The tool passes caller-provided feedback fields to a helper that posts JSON to the portal's /api/feedback endpoint. - **Rationale:** The agent-directed guidance creates a real but conditional risk of feedback submission without user request. The submission path uses the configured portal and the tool describes excluding project contents and secrets, so the inspected behavior supports a warning rather than a block. - **Files touched:** dist/feedback.js, dist/index.js, dist/portalClient.js - **Network endpoints:** /api/feedback ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The feedback guidance tells the connected agent to send feedback even when the user did not request it., The feedback tool forwards caller-provided title and detail to the feedback helper; the helper posts JSON to /api/feedback., Requests use the configured portal URL and its bearer token, so the source does not establish an unrelated package-selected recipient. - **Evidence against:** The feedback tool advises excluding project contents and secret values., Feedback submission requires the connected agent to invoke the tool; no automatic submission of user-authored feedback content was established. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.28. - Review the evidence and your use of @funny-booth/agent-core@0.1.28 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.
