- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 0.3.3
- **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.

User-invoked launcher and installed agent hooks can fetch and execute a remote overlay binary. The package also auto-installs Bun through a remote shell installer if absent.

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:** User-invoked launcher and installed agent hooks can fetch and execute a remote overlay binary. The package also auto-installs Bun through a remote shell installer if absent.

- **Trigger:** Run gamepigeon, invoke an installed Tui agent hook, or explicitly run gamepigeon install.

- **Impact:** A compromised release or Bun-install endpoint could obtain code execution in the invoking user's context.

- **Evidence paths:** package.json, scripts/run-with-bun.cjs, scripts/overlay.ts, scripts/install-adapters.sh, scripts/manage-harness-hooks.ts, src/auth.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-08-06T18:03:22.825Z

### AI review details

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

- **Mechanism:** Remote binary/bootstrap download followed by local execution and optional agent-hook persistence.

- **Rationale:** The code implements its stated overlay and agent-integration features, so there is no concrete malicious chain. However, it provides persistent agent hooks plus remotely supplied executable code without an independent pinned signature, which is a material supply-chain risk.

- **Files touched:** scripts/run-with-bun.cjs, scripts/overlay.ts, ~/.gamepigeon/bin/0.3.3/gamepigeon-overlay, ~/.gamepigeon/runtime, ~/.codex/hooks.json, ~/.claude/settings.json, ~/.agents/hooks.json

- **Network endpoints:** https://releases.runretroarcade.com, https://bun.sh/install, https://auth.runretroarcade.com, https://us.i.posthog.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** scripts/run-with-bun.cjs pipes a remote Bun installer to a shell when the CLI/hook lacks Bun., scripts/overlay.ts downloads a platform native binary from releases.runretroarcade.com and executes it., The binary hash is supplied by the same remote manifest, so it is not an independently pinned trust root., scripts/install-adapters.sh, when explicitly invoked, installs persistent Codex/Claude/Antigravity agent hooks.

- **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Agent configuration changes require the explicit gamepigeon install command., Auth requests use the package's stated auth service and locally stored session token; no general credential harvesting was found., No source evidence of destructive actions, secret exfiltration, or hidden install-time execution.

## Affected versions and remediation

This report applies to @tui-games/tui@0.3.3.

- Review the evidence and your use of @tui-games/tui@0.3.3 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.
