Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No attack was identified in the inspected package sources. The flagged process and network behavior runs a local OpenCode server and checks its readiness over loopback. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-07T23:53:33.375Z - **Finished:** 2026-10-07T23:54:22.887Z - **Download time:** 520 ms - **Static scan time:** 1425 ms - **AI review time:** 47567 ms - **Total time:** 49512 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 attack was identified in the inspected package sources. The flagged process and network behavior runs a local OpenCode server and checks its readiness over loopback. - **Trigger:** Importing the package entrypoint or invoking the serve launcher. - **Impact:** No malicious effect was established from the inspected behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T23:54:22.887Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher starts the OpenCode binary on 127.0.0.1 and sends a Basic-authenticated readiness request to that local server; the flagged plugin location is documentation. - **Rationale:** Source inspection found no install lifecycle hook or concrete malicious behavior. The reverse-shell-style scanner hint corresponds to launching OpenCode locally and probing its loopback server; the flagged plugin location is documentation rather than a configuration write. - **Files touched:** package.json, dist/index.js, dist/serve.js, dist/plugin/index.js - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. - **Evidence for AI clean decision:** package.json exports dist/index.js and defines no install lifecycle hook., dist/serve.js launches the configured OpenCode binary as a serve process bound to 127.0.0.1., dist/serve.js sends its authenticated readiness request to that same loopback server., The flagged dist/plugin/index.js location is documentation describing user-local persona files and examples, not an agent configuration mutation., The OpenCode launch passes its supplied credentials, servers, and user-auth data to materialEnv. ## Affected versions and remediation This report applies to @cotal-ai/connector-opencode@0.73.0. - Review the evidence and your use of @cotal-ai/connector-opencode@0.73.0 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.
