## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 0.43.0
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

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:** A managed Cotal launch can start an OpenCode agent with an injected plugin and permissive tool mode. It is not activated during npm installation and the local OpenCode server is loopback-bound.

- **Trigger:** A Cotal manager invokes the connector's managed OpenCode launch.

- **Impact:** A mesh-driven agent may use the permissions of the user who deliberately launches it.

- **Evidence paths:** dist/index.js, dist/serve.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-05T10:45:53.869Z

### AI review details

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

- **Mechanism:** Starts an OpenCode subprocess with injected plugin configuration and permission allow.

- **Rationale:** This is a real AI-agent capability with a broad runtime permission model, so it warrants a warning. Source inspection does not establish malicious installation behavior, persistence, exfiltration, or remote command-and-control.

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

- **Network endpoints:** 127.0.0.1

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 84.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Managed launches inject an OpenCode plugin and set its permission mode to allow., The launch shim starts an OpenCode child process and creates a local server database and PID file., This creates a user-invoked agent-control capability, but not an install-time payload.

- **Evidence against:** package.json has no preinstall, install, postinstall, or bin entrypoint., The helper binds the OpenCode server only to 127.0.0.1., No credential harvesting, remote shell, or automatic external network target was confirmed.

## Affected versions and remediation

This report applies to @cotal-ai/connector-opencode@0.43.0.

- Review the evidence and your use of @cotal-ai/connector-opencode@0.43.0 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
