## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 17 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 0.4.8
- **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.

An explicit CLI setup installs global AI-agent hooks that launch the overlay during agent lifecycle events. The launcher can download and execute both a Bun installer and an overlay binary.

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:** An explicit CLI setup installs global AI-agent hooks that launch the overlay during agent lifecycle events. The launcher can download and execute both a Bun installer and an overlay binary.

- **Trigger:** The user runs gamepigeon install, then an installed agent lifecycle event or overlay launch occurs.

- **Impact:** A remote service can supply code that executes with the invoking user's permissions.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-11T02:59:44.212Z

### AI review details

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

- **Mechanism:** Global agent-hook installation plus remotely downloaded executable launch.

- **Rationale:** No npm lifecycle hook or self-dependency chain establishes automatic install-time abuse. The explicit setup and remote executable bootstrap remain a material unresolved risk, so this should be warned rather than blocked.

- **Files touched:** ~/.codex/hooks.json, ~/.claude/settings.json, ~/.agents/hooks.json, ~/.gamepigeon/bin, scripts/install-adapters.sh, scripts/manage-harness-hooks.ts, scripts/run-with-bun.cjs, scripts/overlay.ts

- **Network endpoints:** bun.sh, releases.runretroarcade.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The explicit install command writes skills and lifecycle hooks into several user-global AI-agent configuration areas., Those hooks invoke the package launcher on agent session and prompt events., The launcher silently fetches and executes Bun's remote installer when Bun is absent., The overlay downloads an executable and executes it; its checksum is supplied by the same remote release service.

- **Evidence against:** package.json has no npm preinstall, install, or postinstall lifecycle hook., The configuration mutation is reached through an explicit CLI install command, not package installation., No runtime dependency on this package name or source evidence of credential harvesting was found.

## Affected versions and remediation

This report applies to @tui-games/tui@0.4.8.

- Review the evidence and your use of @tui-games/tui@0.4.8 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.
