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. Source inspection found an Android-oriented bundle installer and a launcher for the bundled CLI. Its configuration setup preserves existing files, and no concrete attack behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T23:04:48.579Z - **Finished:** 2026-10-09T23:05:09.074Z - **Download time:** 1532 ms - **Static scan time:** 78 ms - **AI review time:** 18884 ms - **Total time:** 20495 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. The package installs a Termux-compatible upstream CLI bundle and supplies default configuration when none exists. - **Trigger:** The package postinstall hook runs, or the user invokes the launcher. - **Impact:** The inspected behavior is consistent with the package's Termux CLI purpose; existing OpenCode configuration files are left in place. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T23:05:09.074Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer fetches runtime and CLI archives for the bundle; the launcher invokes the bundled CLI and exposes explicit update and diagnostic commands. - **Rationale:** Source inspection found an Android-oriented bundle installer and a launcher for the bundled CLI. Its configuration setup preserves existing files, and no concrete attack behavior was identified. - **Files touched:** package.json, bin/opencode-termux.js, install.mjs ### 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; it skips setup outside Android unless explicitly forced., The installer downloads the upstream OpenCode bundle and Alpine runtime components to assemble the Termux bundle., The installer adds default OpenCode configuration only when the user has no existing file., The launcher dispatches update, diagnostic, and version commands explicitly, then runs the bundled CLI for other arguments. ## Affected versions and remediation This report applies to @nemoobc/opencode-termux@1.20.16. - Review the evidence and your use of @nemoobc/opencode-termux@1.20.16 before allowing it.
