Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 16.15.0 - **Selected version is latest:** Yes - **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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 79.0% - **Started:** 2026-10-08T22:14:31.171Z - **Finished:** 2026-10-08T22:15:08.754Z - **Download time:** 1532 ms - **Static scan time:** 5045 ms - **AI review time:** 31005 ms - **Total time:** 37583 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 package provides a Pi extension and an explicit CLI installer that can place its own router plugin in OpenCode configuration. This is a first-party agent integration capability; the inspected sources do not establish an active attack. - **Trigger:** A user invokes the package CLI's install command; Pi may load the extension when the package is configured for Pi. - **Impact:** The package can add its own agent plugin and extension to supported agent environments. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T22:15:08.754Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer copies the package-owned router plugin into the OpenCode plugins directory and registers it in managed state. - **Rationale:** Source inspection supports a warning for explicit setup of a first-party agent extension and plugin, not a confirmed attack. The scanner-supplied integration locations are fixture content or managed-block cleanup and do not show malicious behavior. - **Files touched:** package.json, bin/ocskill.mjs, lib/installer.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 79.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package declares Pi extensions, including pi/extensions/ues.ts., The CLI's install command calls installResources, which can copy the package's router plugin into the OpenCode plugins directory., The three scanner-supplied agent configuration locations are fixture content or cleanup of a managed AGENTS.md block; they do not establish an attack. - **Evidence against:** The installer capability is activated through the package CLI's install command; the inspected code does not show it running from an npm install hook., The two fixture files generate test instructions, and the installer location removes only a managed block from AGENTS.md. ## Affected versions and remediation This report applies to opencode-agent-skill@16.15.0. - Review the evidence and your use of opencode-agent-skill@16.15.0 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.
