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:** 16.6.1 - **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. LPM treats this as warn-only first-party agent extension lifecycle risk. The explicit installer can add this package’s router plugin to the OpenCode configuration. This is first-party agent extension setup and presents a guarded extension lifecycle risk; no concrete attack was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-08T19:24:14.474Z - **Finished:** 2026-10-08T19:25:15.320Z - **Download time:** 780 ms - **Static scan time:** 3911 ms - **AI review time:** 56154 ms - **Total time:** 60846 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 explicit installer can add this package’s router plugin to the OpenCode configuration. This is first-party agent extension setup and presents a guarded extension lifecycle risk; no concrete attack was established. - **Trigger:** A user runs the CLI install or sync command while using OpenCode 2 or later. - **Impact:** OpenCode can load the installed plugin and its agent capabilities. - **Evidence paths:** lib/installer.mjs, global-config/plugins/ues-router/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-08T19:25:15.320Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer copies the package-owned router plugin and command templates into the OpenCode plugins configuration. - **Rationale:** The package installs a first-party agent plugin only through an explicit CLI command, which warrants a warning under the agent extension policy. There is no automatic npm install trigger or source evidence establishing a concrete attack. - **Files touched:** lib/installer.mjs, global-config/plugins/ues-router/index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest has a prepublish-only release check; the installer runs from the explicit CLI install or sync command., On OpenCode 2 or later, that command copies the package-owned router plugin into the OpenCode plugins directory and adds prompt aliases., The installer integration location handles only the package-managed AGENTS.md block; the retrieval and repo-scale AGENTS.md locations are generated test fixtures, and the Pi extension location reads project AGENTS.md for a hash., The router plugin is a package-owned agent extension with filesystem and process capabilities. - **Evidence against:** No npm preinstall, install, or postinstall hook is declared., The reviewed behavior requires a user to run the install or sync command; no concrete credential theft, unrelated network transfer, or destructive attack was identified. ## Affected versions and remediation This report applies to opencode-agent-skill@16.6.1. - Review the evidence and your use of opencode-agent-skill@16.6.1 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.
