## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 13 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:** 1.20.18
- **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.

Source inspection found an install hook that downloads and assembles the CLI bundle, and a launcher that performs Termux setup and starts it on invocation. The observed behavior is package-aligned and no concrete malicious behavior was identified.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 89.0%

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 malicious attack surface was identified in the inspected manifest, installer, and launcher. Installation fetches upstream components, while the launcher configures missing Termux DNS files and runs the CLI.

- **Trigger:** Package installation runs the postinstall hook; launcher actions occur when the user invokes the command.

- **Impact:** These actions support installing and running the Termux CLI; no credential theft, unrelated project mutation, or hidden execution chain was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T23:05:05.477Z

### AI review details

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

- **Mechanism:** The installer downloads upstream binary and Alpine components into its vendor directory. The launcher creates DNS files only if absent and starts the bundled executable.

- **Rationale:** Source inspection found an install hook that downloads and assembles the CLI bundle, and a launcher that performs Termux setup and starts it on invocation. The observed behavior is package-aligned and no concrete malicious behavior was identified.

- **Files touched:** install.mjs, bin/opencode-termux.js, package.json

- **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 manifest's postinstall runs the package's installer., The installer downloads the configured upstream binary and performs gzip and size checks; it also fetches supporting Alpine components., The launcher writes DNS configuration only when the files are absent, then runs its bundled CLI when invoked.

- **Evidence against:** The inspected network and file operations align with installing and running the Termux CLI; no credential collection or unrelated control-surface mutation was identified.
