## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 15 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 1.20.13
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Static inspection found install-time downloading and execution of OpenCode components that are consistent with the package’s Termux launcher purpose. The inspected code did not establish a concrete attack surface, so the package is clean.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 89.0%
- **Started:** 2026-10-09T23:04:34.433Z

- **Static scan time:** 69 ms
- **AI review time:** 30085 ms
- **Total time:** 30913 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 inspected install and launcher behavior matches the package’s purpose of installing and running OpenCode on Termux.

- **Trigger:** Package installation runs the postinstall hook; later, the user runs the exposed CLI or its update command.

- **Impact:** No unrelated project files, credentials, or broad agent control settings were shown to be modified. The installer’s remote binary download is package-aligned, though the inspected 2.x path does not verify a cryptographic digest.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T23:05:05.346Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The installer fetches the OpenCode binary and supporting libraries, prepares the package bundle, and may copy default OpenCode config files if none exist. The launcher executes the bundled CLI.

- **Rationale:** Static inspection found install-time downloading and execution of OpenCode components that are consistent with the package’s Termux launcher purpose. The inspected code did not establish a concrete attack surface, so the package is clean.

- **Files touched:** vendor/, $HOME/.config/opencode/opencode.json, $HOME/.config/opencode/cli.json, $TERMUX\_PREFIX/etc/resolv.conf, $TERMUX\_PREFIX/etc/hosts

- **Network endpoints:** opencode.ai, dl-cdn.alpinelinux.org, registry.npmjs.org

### Review decision

- **Verdict:** Clean

- **Confidence:** 89.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The postinstall hook runs the package’s installer, and the launcher runs the bundled OpenCode CLI or invokes that installer when bundle files are missing., The installer downloads an OpenCode binary from opencode.ai for this package’s stated purpose, then runs it with --version as a smoke test., Installer config setup only copies package-provided OpenCode config files when the destination files do not already exist.

- **Evidence against:** The Android install path downloads and executes a remote binary; for upstream version 2.x, the inspected code checks gzip validity and file size rather than a cryptographic digest.
