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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-05T10:24:18.589Z - **Finished:** 2026-10-05T10:25:47.564Z - **Download time:** 765 ms - **Static scan time:** 49 ms - **AI review time:** 88159 ms - **Total time:** 88975 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:** Explicit setup can replace project agent instructions and refresh existing harnesses. A separately launched voice server exposes unauthenticated Claude investigation requests on its listening interfaces. - **Trigger:** Running the catalyst-os CLI in a project, or separately launching the voice server. - **Impact:** Project agent behavior can change, and reachable clients can request codebase investigations through the user's Claude session. No confirmed malicious install-time attack was established. - **Evidence paths:** .catalyst/bin/install.js, .catalyst/voice/meet-server.js - **Review source:** ai\_review - **Reviewed:** 2026-10-05T10:25:47.564Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Setup copies behavior-bearing agent files into the current directory; the HTTP server forwards caller-supplied investigation prompts to Claude without authentication or a loopback binding. - **Rationale:** The scanner's blocking claim is not supported by the installer's working-directory selection and self-copy guard. Explicit agent configuration mutation and the exposed voice bridge warrant a behavior-specific warning. - **Files touched:** AGENTS.md, .claude, .pi, .codex ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json automatically runs the installer after installation., The installer targets the current working directory and skips copying files onto themselves., Explicit CLI setup copies skills and overwrites AGENTS.md in the selected project., Setup also refreshes existing agent harness directories without separate approval., The separately launched voice server accepts unauthenticated investigation requests and listens without a loopback host restriction. - **Evidence against:** Normal npm lifecycle execution targets the installed package directory; inspected source does not redirect installation to the consuming project., No runtime self-dependency, obfuscated payload, or covert credential export was found in the inspected files., Voice authentication sends the user-supplied ElevenLabs key to the fixed ElevenLabs API destination. ## Affected versions and remediation This report applies to catalyst-os@3.11.0. - Review the evidence and your use of catalyst-os@3.11.0 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.
