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:** 0.2.25 - **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 package's install hook is hint-only, but explicit OMP setup installs an extension that participates in provider requests. This warrants a warning for guarded first-party agent extension setup, not a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-09T06:29:17.106Z - **Finished:** 2026-10-09T06:29:43.440Z - **Download time:** 512 ms - **Static scan time:** 1588 ms - **AI review time:** 24233 ms - **Total time:** 26334 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 was identified. The package can install a first-party OMP extension that starts its local proxy for requests using the package's zcode provider. - **Trigger:** The user runs the package's setup command and later makes an OMP request with the zcode provider selected. - **Impact:** The extension adds package-controlled behavior to OMP requests using zcode, creating a guarded agent-extension lifecycle risk. - **Evidence paths:** cli/adapters/omp.mjs, proxy/zcode-proxy-autostart.ts - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:29:43.440Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Setup writes the package-owned extension and registers it; the extension performs a local proxy preflight for matching requests. - **Rationale:** The package's install hook is hint-only, but explicit OMP setup installs an extension that participates in provider requests. This warrants a warning for guarded first-party agent extension setup, not a block. - **Files touched:** ~/.omp/agent/extensions/zcode-proxy-autostart.ts, ~/.omp/agent/config.yml, ~/.omp/agent/models.yml - **Network endpoints:** 127.0.0.1 ### 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 runs a setup script in hint-only mode; the script prints instructions to run setup explicitly., The OMP adapter writes and registers a package-owned extension in the user's OMP agent directory during setup., The extension starts the local proxy only before a request using the zcode provider. - **Evidence against:** The Aider adapter writes its key to a process-local environment file and points its API base at the local proxy., The inspected setup path does not automatically configure agent integrations during postinstall. ## Affected versions and remediation This report applies to zcode-agent-kit@0.2.25. - Review the evidence and your use of zcode-agent-kit@0.2.25 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.
