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:** 0.2.21 - **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 install hook is limited to a setup hint, while explicit CLI setup can install an extension that runs within OMP's request lifecycle. This warrants a warning for guarded agent extension setup, but the inspected behavior does not establish a concrete malicious attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-09T06:28:42.953Z - **Finished:** 2026-10-09T06:29:04.763Z - **Download time:** 260 ms - **Static scan time:** 1255 ms - **AI review time:** 20294 ms - **Total time:** 21810 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 OMP setup installs a package-owned extension that can start the local proxy for zcode requests. - **Trigger:** The user runs the CLI setup or integration command and later makes an OMP request using the zcode provider. - **Impact:** This adds package-controlled code to the agent extension lifecycle and can start the local proxy. The inspected source does not establish a remote attack or credential exfiltration path. - **Evidence paths:** cli/adapters/omp.mjs, proxy/zcode-proxy-autostart.ts - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:29:04.763Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The adapter writes the extension into OMP's extensions directory; the extension reads the local kit key, checks the loopback health endpoint, and runs the preflight when needed. - **Rationale:** The install hook is limited to a setup hint, while explicit CLI setup can install an extension that runs within OMP's request lifecycle. This warrants a warning for guarded agent extension setup, but the inspected behavior does not establish a concrete malicious attack. - **Files touched:** cli/adapters/omp.mjs, proxy/zcode-proxy-autostart.ts - **Network endpoints:** http://127.0.0.1:\_\_ZCODE\_OM\_PORT\_\_/health ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook only prints a setup hint; it does not invoke setup., The OMP adapter writes a package-owned autostart extension into the user's OMP extensions directory during setup., The extension runs on OMP provider requests and starts a local health check using the kit key., The CLI exposes setup and integration as explicit commands. - **Evidence against:** The inspected install hook does not automatically mutate agent configuration., The extension's health request targets a loopback address, and its start behavior is gated on the selected provider being zcode. ## Affected versions and remediation This report applies to zcode-agent-kit@0.2.21. - Review the evidence and your use of zcode-agent-kit@0.2.21 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.
