## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.72.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

No attack was identified. The launcher starts an OpenCode service for the connector on loopback and authenticates its local readiness request.

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 launcher starts an OpenCode service for the connector on loopback and authenticates its local readiness request.

- **Trigger:** The exported launcher is invoked to start an OpenCode session.

- **Impact:** The inspected behavior provides a local connector service; no malicious remote control or credential exfiltration was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-07T22:42:08.799Z

### AI review details

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

- **Mechanism:** It starts the OpenCode serve process on 127.0.0.1, assigns a per-agent data directory, and uses Basic authentication for its loopback readiness request.

- **Rationale:** The manifest has no install lifecycle hook, and the flagged process and socket behavior is a loopback OpenCode launcher. The required plugin location is embedded documentation rather than executable agent-configuration behavior.

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

- **Network endpoints:** 127.0.0.1

### Review decision

- **Verdict:** Clean

- **Confidence:** 90.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Final policy explanation:** The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior.

- **Evidence for AI clean decision:** package.json defines test, typecheck, build, and bundle scripts but no preinstall, install, or postinstall hook., dist/serve.js starts OpenCode's serve process bound to 127.0.0.1 and assigns it a pinned agent data directory., dist/serve.js sends a locally generated or environment-provided password as Basic authentication to the loopback server., The required dist/plugin/index.js location is embedded persona documentation about user-local files and examples; it does not perform agent configuration or plugin installation.
