Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 1.5.74 - **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 source supports a warning for first-party agent extension setup: eligible runtime sessions load bundled workflow skills through a plugin directory. The inspected postinstall hook unpacks platform tools, and the supplied integration locations do not establish a separate attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 79.0% - **Started:** 2026-10-15T08:35:49.280Z - **Finished:** 2026-10-15T08:38:01.081Z - **Download time:** 4349 ms - **Static scan time:** 11141 ms - **AI review time:** 116310 ms - **Total time:** 131801 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 concrete malware chain was identified. Eligible sessions install and load a package-bundled workflow plugin from Thalamus's home directory. - **Trigger:** Launching a session type that enables workflow skills when the Claude executable supports plugin directories. - **Impact:** The launched Claude session can use the bundled workflow skills; no broader agent configuration change was established. - **Evidence paths:** dist/api-C5lncKMu.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-15T08:38:01.081Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package materializes its bundled skill files under the Thalamus home directory and passes that directory to Claude. - **Rationale:** The source supports a warning for first-party agent extension setup: eligible runtime sessions load bundled workflow skills through a plugin directory. The inspected postinstall hook unpacks platform tools, and the supplied integration locations do not establish a separate attack. - **Files touched:** Thalamus home directory/plugins/workflows/\ ### Review decision - **Verdict:** Suspicious - **Confidence:** 79.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook runs a tool unpacker that extracts platform-specific archives., The four supplied agent-integration locations concern Claude project paths and friction-metrics state., Runtime code writes bundled workflow skills as a plugin under Thalamus's home directory., Eligible session types pass that plugin directory to Claude when launching a session., The unpacking code selects archives by the current platform. ## Affected versions and remediation This report applies to thalamus@1.5.74. - Review the evidence and your use of thalamus@1.5.74 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.
