## 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:** 1.5.10
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

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.

## Security analysis

### Published attack-surface review

- **Summary:** An explicit lgy setup can add agent hooks that mediate tool calls through LinkGravity's local approval service. Voice mode uploads user audio for speech recognition.

- **Trigger:** User runs lgy setup and consents; voice transcription is used.

- **Impact:** The package gains agent tool-call mediation capability and processes voice content remotely.

- **Evidence paths:** package.json, bin/setup.js, npm-scripts/register-hook.js, hooks/hook.py, hooks/stop\_hook.py, voice-service/stt.js, npm-scripts/prepare.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-15T02:28:04.341Z

### AI review details

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

- **Mechanism:** User-consented agy hook registration and Google STT upload.

- **Rationale:** No concrete malicious chain, unconsented lifecycle mutation, remote payload execution, or credential exfiltration was found. The explicit user-command agent hook mutation remains a meaningful capability risk under firewall policy.

- **Files touched:** .gemini/config/hooks.json, hooks/hook.py, hooks/stop\_hook.py

- **Network endpoints:** http://localhost:18080/approve, https://www.google.com/speech-api/v2/recognize

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 92.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for:** Explicit setup can register PreToolUse and Stop hooks in agy's user config., The registered hook forwards agent tool names and arguments to a local approval service., Voice mode sends audio to Google's speech-recognition endpoint.

- **Evidence against:** No preinstall, install, or postinstall lifecycle hook is declared., Agent-hook registration is invoked only after an interactive consent prompt., The approval endpoint is loopback-only; no secret or credential exfiltration was found., The prepare hook is documented dev-only and installs only local checkout tooling.
