## Security analysis

### Published attack-surface review

- **Summary:** No confirmed attack surface was identified. The package is a user-invoked OpenCode connector and local launcher.

- **Trigger:** A caller launches the registered connector.

- **Impact:** No unconsented installation-time execution, credential export, or destructive behavior was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-25T21:14:55.966Z

### AI review details

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

- **Mechanism:** It starts the bundled shim with constructed environment values; the shim uses a loopback OpenCode endpoint.

- **Rationale:** Static inspection found no lifecycle hook or concrete malicious behavior. The observed process and network behavior is aligned with a local connector launch.

- **Files touched:** dist/serve.js

- **Network endpoints:** http://127.0.0.1:${port}

### Review decision

- **Verdict:** Clean

- **Confidence:** 87.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Final policy explanation:** The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason.

- **Evidence for AI clean decision:** The manifest exposes the module entrypoint and has no install lifecycle hook., The launcher uses a loopback URL and a caller-provided data root., The connector builds an explicit launch environment and starts its bundled serve shim., The plugin remains inactive when the managed-session identity is absent.

## Affected versions and remediation
