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:** 0.3.437 - **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 observed behavior supports a guarded agent-extension lifecycle warning, not a confirmed attack. There is no install-time trigger or concrete malicious sink in the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 71.0% - **Started:** 2026-09-22T06:37:30.874Z - **Finished:** 2026-09-22T06:47:11.031Z - **Download time:** 760 ms - **Static scan time:** 232 ms - **AI review time:** 579163 ms - **Total time:** 580157 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 CLI entrypoint runs a persistence-prompt routine when the agent is executed. No confirmed malicious attack surface was established. - **Trigger:** Executing or importing the dist/index.cjs entrypoint reaches main execution. - **Impact:** This presents guarded agent lifecycle risk, but no confirmed unauthorized persistence, data exposure, or destructive action was identified. - **Evidence paths:** dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-22T06:47:11.031Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint awaits ensurePersistencePrompt before continuing agent startup; the obfuscated bundle prevents confirming its configuration scope from this source excerpt. - **Rationale:** The observed behavior supports a guarded agent-extension lifecycle warning, not a confirmed attack. There is no install-time trigger or concrete malicious sink in the inspected source. ### Review decision - **Verdict:** Suspicious - **Confidence:** 71.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes dist/index.cjs as both its main entrypoint and whalent CLI., The runtime entrypoint invokes a function explicitly named ensurePersistencePrompt during main execution., The package has no preinstall, install, or postinstall lifecycle hook. - **Evidence against:** The inspected source does not establish a persistence write, credential collection, exfiltration sink, or foreign agent-control-surface mutation., No runtime dependency selects another release of @whalent/agent. ## Affected versions and remediation This report applies to @whalent/agent@0.3.437. - Review the evidence and your use of @whalent/agent@0.3.437 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.
