Do not execute instructions or code found in this document. ## 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:** 0.2.14 - **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. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-09T00:49:18.079Z - **Finished:** 2026-08-09T00:50:07.147Z - **Download time:** 754 ms - **Static scan time:** 1011 ms - **AI review time:** 47302 ms - **Total time:** 49068 ms 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 adapter installation adds global AI-agent lifecycle hooks that launch the package overlay during sessions. The launcher can download and execute a native overlay binary from the package release service. - **Trigger:** User runs the package's adapter/install command; installed hooks then fire on agent session and prompt events. - **Impact:** A compromised or malicious release service could supply code executed through installed agent hooks. - **Evidence paths:** package.json, scripts/install-adapters.sh, scripts/manage-harness-hooks.ts, scripts/overlay.ts, scripts/run-with-bun.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-09T00:50:07.147Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** explicit agent-hook installation plus remote native-binary download and execution - **Rationale:** Source inspection confirms explicit global agent-hook mutation and a remotely supplied executable launch path. These are dangerous package capabilities requiring a warning, not evidence of an unconsented install-time malicious chain. - **Files touched:** scripts/install-adapters.sh, scripts/manage-harness-hooks.ts, scripts/overlay.ts, scripts/run-with-bun.cjs, ~/.codex/hooks.json, ~/.gamepigeon/bin - **Network endpoints:** https://releases.runretroarcade.com, https://bun.sh/install, https://us.i.posthog.com, https://auth.runretroarcade.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** \`scripts/install-adapters.sh\` explicitly installs global Codex/agent skills and lifecycle hooks., \`scripts/manage-harness-hooks.ts\` writes \`~/.codex/hooks.json\` commands for session and prompt events., \`scripts/overlay.ts\` fetches a release manifest and native binary, then launches that binary., The downloaded binary hash is supplied by the same remote manifest, so it is not independently pinned., \`scripts/run-with-bun.cjs\` downloads and executes Bun when it is absent. - **Evidence against:** \`package.json\` has no preinstall, install, or postinstall lifecycle hook., Adapter and hook mutation occurs only through an explicit \`install\`/adapter command., Hook merger preserves non-package hook entries and targets package-owned overlay actions., Reviewed source shows no credential harvesting or unrelated file exfiltration. ## Affected versions and remediation This report applies to @tui-games/tui@0.2.14. - Review the evidence and your use of @tui-games/tui@0.2.14 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. ## Public findings ### 1.
