## 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:** 0.2.20
- **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.

This is a real automated AI-agent extension setup with enabled unpinned npx channels, but the inspected source is transparent, preserves differing user configuration, and has no exfiltration, destructive behavior, or self-dependency chain. It warrants a warning rather than a publication block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 86.0%
- **Started:** 2026-09-11T20:19:11.436Z

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:** Installation modifies the consuming workspace's OpenCode extension area. If no configuration exists, it enables MCP commands that invoke npx packages later.

- **Trigger:** npm installation, followed by OpenCode starting the installed MCP configuration

- **Impact:** The package can alter an AI-agent control surface and introduce later remote package execution.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-11T20:20:01.790Z

### AI review details

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

- **Mechanism:** Postinstall deployment of OpenCode agents, commands, and an enabled MCP configuration

- **Rationale:** This is a real automated AI-agent extension setup with enabled unpinned npx channels, but the inspected source is transparent, preserves differing user configuration, and has no exfiltration, destructive behavior, or self-dependency chain. It warrants a warning rather than a publication block.

- **Files touched:** .opencode/agents/, .opencode/commands/, .opencode/opencode.json, tera-system/, tools/, project-control/, tera-workshop/

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The package runs its installer automatically after installation., The installer targets the consumer workspace through INIT\_CWD and writes OpenCode agent and command files., It creates an OpenCode configuration when absent and enables MCP commands that use npx., The installed configuration can fetch and execute unpinned MCP packages when OpenCode starts them.

- **Evidence against:** No runtime dependency on another release of this package is declared., The installer preserves a differing existing OpenCode configuration and does not contain network or credential-exfiltration code., The build helper is not an install hook and only packages local content.

## Affected versions and remediation

This report applies to @tera-system/core@0.2.20.

- Review the evidence and your use of @tera-system/core@0.2.20 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.
