The full behavior of the agent integration and installer remains unresolved. - **Trigger:** Unresolved; the inspected excerpts do not establish the relevant integration trigger. - **Impact:** No malicious impact was confirmed; the available citations do not cover all required source paths and integration behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T19:25:02.280Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The excerpts show fixture generation, project instruction-file inspection, process launching, and project-scoped browser dependency resolution, but do not establish a malicious chain. - **Rationale:** The inspected source excerpts do not establish malicious behavior, but they also do not resolve the full agent integration and installer flow. A clean decision cannot be supported within the eight-citation limit given the required source coverage, so this requires manual review. ### Review decision - **Verdict:** Manual Review - **Confidence:** 61.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json shows a prepublishOnly release check; no npm install lifecycle hook is shown in the inspected scripts., The retrieval fixture generates an AGENTS.md test file as deterministic fixture content., The installer excerpt reads an AGENTS.md file and checks for its managed block; this excerpt does not establish the complete install behavior., The repo-scale fixture writes fixture instructions to AGENTS.md., The Pi extension reads a project AGENTS.md file to compute a prefix hash., The Python finding is a small role check that permits editing only for an admin user., The process runner launches a supplied executable with caller-provided working directory and environment options., The browser runtime resolves Playwright dependencies from the supplied project root. - **Evidence against:** No malicious action is established by the inspected excerpts., The cited fixture and runtime excerpts are consistent with test generation, project context inspection, and project-scoped dependency loading. ## Affected versions and remediation This report applies to opencode-agent-skill@16.2.0. - Review the evidence and your use of opencode-agent-skill@16.2.0 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.
