Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The automatic install behavior is consistent with setting up this Termux OpenCode package and is gated to Android unless explicitly forced. The configuration writes preserve existing user files, and the inspected launcher and installer did not establish a concrete attack surface warranting a warning or block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T23:04:54.596Z - **Finished:** 2026-10-09T23:05:36.903Z - **Download time:** 250 ms - **Static scan time:** 91 ms - **AI review time:** 41964 ms - **Total time:** 42307 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 confirmed malicious attack was identified. The postinstall installer is platform-gated and installs the package’s own OpenCode runtime and default configuration. - **Trigger:** Package installation runs postinstall; the launcher’s additional setup runs when the user invokes it. - **Impact:** These actions alter the Termux environment and may add a default OpenCode configuration, but inspected source showed no credential exfiltration or broad agent-control mutation. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T23:05:36.903Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer fetches the upstream binary and runtime libraries, creates missing Termux DNS files, and copies package-provided configuration only when no user configuration exists. - **Rationale:** The automatic install behavior is consistent with setting up this Termux OpenCode package and is gated to Android unless explicitly forced. The configuration writes preserve existing user files, and the inspected launcher and installer did not establish a concrete attack surface warranting a warning or block. - **Files touched:** package.json, install.mjs, bin/opencode-termux.js - **Network endpoints:** opencode.ai, dl-cdn.alpinelinux.org, registry.npmjs.org ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook runs the installer automatically., The installer skips non-Android systems unless explicitly forced., On Android, the installer downloads and assembles the OpenCode binary and Termux runtime libraries., The installer copies a default OpenCode configuration only when the user has no existing configuration., The launcher creates Termux DNS files if they are missing; no credential collection or unrelated agent-control mutation was identified. - **Evidence against:** The launcher requires the user to invoke it, and update is a separate command., The installed default configuration contains only a model selection and key bindings. ## Affected versions and remediation This report applies to @nemoobc/opencode-termux@1.20.19. - Review the evidence and your use of @nemoobc/opencode-termux@1.20.19 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.
