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:** 0.2.39 - **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. The inspected lifecycle hook only displays a setup hint, and the flagged dynamic evaluation and network behavior occur in the proxy’s captcha and local account-management functions. The inspected source supports intended package functionality and does not establish an attack surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-09T06:29:16.919Z - **Finished:** 2026-10-09T06:29:48.316Z - **Download time:** 503 ms - **Static scan time:** 1784 ms - **AI review time:** 29109 ms - **Total time:** 31397 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 attack was identified in the inspected source. The flagged execution and network behavior supports the package’s local proxy and captcha functionality. - **Trigger:** The postinstall hook prints an informational message; proxy, captcha, and harness configuration behavior activates when the user runs the relevant commands or proxy. - **Impact:** No confirmed unauthorized mutation, credential exfiltration, or other attack impact was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:29:48.316Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected account request targets the configured proxy host, captcha evaluation loads page content in its runtime, and harness setup edits isolated or managed configuration. - **Rationale:** The inspected lifecycle hook only displays a setup hint, and the flagged dynamic evaluation and network behavior occur in the proxy’s captcha and local account-management functions. The inspected source supports intended package functionality and does not establish an attack surface. ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook only prints a message asking the user to run setup; it does not run setup automatically., The proxy manager verifies that a process belongs to this package before treating it as its own., The captcha evaluation runs inside the captcha page and loads its SDK content., The flagged account request sends its key to the configured local proxy host., Codex setup creates an isolated home; OMP edits a managed configuration block. ## Affected versions and remediation This report applies to zcode-agent-kit@0.2.39. - Review the evidence and your use of zcode-agent-kit@0.2.39 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.
