## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.2.9
- **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.

Source inspection confirms automatic consumer-project mutation of an AI-agent control surface, but not a concrete malicious payload or exfiltration path. This warrants a warning rather than a publication block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 90.0%

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:** Installing the package automatically changes the consumer project's OpenCode configuration and adds agent content. This is a lifecycle-based agent extension risk, but no concealed payload or automatic network activity was confirmed.

- **Trigger:** npm installation runs postinstall.

- **Impact:** A new OpenCode project can receive enabled MCP command definitions and a large agent control surface without an explicit setup command.

- **Evidence paths:** package.json, scripts/install.js, opencode.tera.example.json, scripts/lib/license.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-29T21:53:46.393Z

### AI review details

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

- **Mechanism:** Copies package-owned agent, command, configuration, tool, and asset files into the consuming project.

- **Rationale:** Source inspection confirms automatic consumer-project mutation of an AI-agent control surface, but not a concrete malicious payload or exfiltration path. This warrants a warning rather than a publication block.

- **Files touched:** .opencode/agents/\*\*, .opencode/commands/\*\*, .opencode/opencode.json, .opencode/opencode.tera.example.json, .opencode/tera-core.manifest.json, tera-system/\*\*, tools/\*\*, assets/\*\*, project-control/\*\*, .tera/license.state.json

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** An automatic postinstall invokes the installer., The installer targets the consuming project through INIT\_CWD., It installs agent and command files into the consumer's .opencode directory., It creates an OpenCode configuration that enables local npx MCP commands., The installer also copies package tools, system files, and assets into the consumer project.

- **Evidence against:** The installer preserves conflicting unowned files and backs up files it owns., No network, shell execution, eval, or dynamic code loading appears in the automatic installer., The manifest has no runtime dependency, including no self-dependency., The PowerShell update and scheduling features require explicit user invocation and parameters.

## Affected versions and remediation

This report applies to @tera-system/core@0.2.9.

- Review the evidence and your use of @tera-system/core@0.2.9 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.
