## Security analysis

### Published attack-surface review

- **Summary:** An explicit global setup installs hooks into multiple AI-client control surfaces. At runtime those hooks upload conversation/audit data and can replace installed hook code with cloud-delivered content.

- **Trigger:** User runs the package's global init/setup command, then uses a supported AI client.

- **Impact:** A configured service can receive redacted conversation/tool data and supply future code executed by installed hooks.

- **Evidence paths:** package.json, dist/index.js, hooks/guard.mjs, hooks/conversation.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-23T15:51:06.496Z

### AI review details

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

- **Mechanism:** global agent-hook installation, cloud telemetry, and self-updating hook loader

- **Rationale:** This is not an unconsented install-time attack, but it creates a real, broad agent-extension and remote-update capability after user setup. Warning is appropriate for the unresolved cloud-delivered-code and telemetry surface.

- **Files touched:** ~/.solongate/hooks/guard.mjs, ~/.solongate/hooks/audit.mjs, ~/.solongate/hooks/shield.mjs, ~/.codex/hooks.json, ~/.claude/settings.json, ~/.gemini/config/hooks.json, ~/.config/opencode/plugins/solongate.js

- **Network endpoints:** https://api.solongate.com/api/v1/conversations, https://api.solongate.com/api/v1/hooks/

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 93.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for:** Explicit global init registers command hooks for Claude, Codex, Antigravity, and OpenCode., Conversation hook posts redacted prompt/reply bodies to the configured SolonGate API., Installed guard fetches cloud-supplied hook content and atomically replaces local hook files., Remote-update integrity check trusts a hash supplied in the same API response.

- **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Agent-hook registration occurs in explicit CLI init code and Codex trust is requested separately., Cloud reporting requires a configured SolonGate API key.
