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:** 15.1.1 - **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 sets up this package's agent resources in OpenCode configuration. This is a guarded first-party agent extension capability; no concrete attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-08T19:21:38.339Z - **Finished:** 2026-10-08T19:22:29.557Z - **Download time:** 1016 ms - **Static scan time:** 2390 ms - **AI review time:** 47809 ms - **Total time:** 51218 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 sets up this package's agent resources in OpenCode configuration. This is a guarded first-party agent extension capability; no concrete attack was identified. - **Trigger:** A user runs ocskill install or ocskill sync. - **Impact:** The setup changes agent instructions and plugin configuration, enabling this package's agent integration. - **Evidence paths:** lib/installer.mjs, bin/ocskill.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-08T19:22:29.557Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer writes a managed workflow block and, for OpenCode 2 or later, copies the package-owned router plugin into the OpenCode plugin directory. - **Rationale:** The source shows first-party agent configuration and plugin setup, activated by an explicit CLI command, with no npm install hook. Under the agent integration policy, this warrants a warning for package-owned extension setup, but the inspected behavior does not establish a malicious attack. - **Files touched:** lib/installer.mjs, bin/ocskill.mjs, lib/repo-scale-fixture.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest defines a prepublishOnly check, not an npm install hook., The installer writes a managed block from the package's workflow into the OpenCode AGENTS.md file., For OpenCode 2 or later, the installer copies the package-owned router plugin into the OpenCode plugin directory., Configuration installation runs through the explicit ocskill install or sync command., The other flagged AGENTS.md write creates instructions inside a generated test fixture. - **Evidence against:** The inspected configuration writes are tied to the explicit CLI install or sync path, not npm installation., The installer targets package-owned resources and adds a managed workflow block; no credential forwarding or unrelated network recipient was identified. ## Affected versions and remediation This report applies to opencode-agent-skill@15.1.1. - Review the evidence and your use of opencode-agent-skill@15.1.1 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.
