Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 19 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.2.40 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found that postinstall only prints a setup hint, while harness configuration is performed through the CLI setup flow. The inspected credential request targets the configured local proxy, and the flagged eval occurs in the captcha solver; these facts do not establish a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-09T06:29:20.328Z - **Finished:** 2026-10-09T06:29:52.462Z - **Download time:** 511 ms - **Static scan time:** 2083 ms - **AI review time:** 29539 ms - **Total time:** 32134 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 confirmed attack surface was identified in the inspected source. The install hook prints a setup hint, and the reviewed credential use targets the configured local proxy. - **Trigger:** Package installation prints the hint; configuration runs after an explicit setup command. - **Impact:** The inspected behavior does not establish credential exfiltration, unconsented broad agent control-surface mutation, or another concrete attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:29:52.462Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected files show a user-invoked harness setup flow, isolated Codex configuration, managed OMP configuration, and local proxy authentication. - **Rationale:** Source inspection found that postinstall only prints a setup hint, while harness configuration is performed through the CLI setup flow. The inspected credential request targets the configured local proxy, and the flagged eval occurs in the captcha solver; these facts do not establish a concrete attack. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json postinstall only prints a setup hint; configuration is selected by a later user command., setup.mjs delegates setup to the CLI only outside the postinstall-hint branch., The inspected proxy authentication request uses its configured local proxy base., The Codex adapter writes configuration under a generated isolated home., The OMP adapter uses a managed configuration block with takeover rules., Captcha eval is part of the guest captcha solver; inspected evidence does not establish an external payload or unrelated execution. ## Affected versions and remediation This report applies to zcode-agent-kit@0.2.40. - Review the evidence and your use of zcode-agent-kit@0.2.40 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.
