## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.89.16
- **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.

This is a user-invoked, first-party agent extension with remote update and telemetry capability, not a malicious install-time chain. Warn so users can evaluate the broad control surface.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 94.0%
- **Started:** 2026-08-27T15:06:50.341Z
- **Finished:** 2026-08-27T15:08:22.661Z
- **Download time:** 251 ms
- **Static scan time:** 6544 ms
- **AI review time:** 85524 ms
- **Total time:** 92320 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:** The package can install global AI-agent hooks only through an explicit CLI setup flow. Those hooks enforce policy, collect configured telemetry, and can self-update from SolonGate.

- **Trigger:** The user runs the package's global setup command, then uses a configured AI tool.

- **Impact:** It can observe or block AI-tool activity and alter agent hook configuration after the user opts in.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-27T15:08:22.661Z

### AI review details

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

- **Mechanism:** Global agent-hook installation with authenticated remote policy and hook updates.

- **Rationale:** This is a user-invoked, first-party agent extension with remote update and telemetry capability, not a malicious install-time chain. Warn so users can evaluate the broad control surface.

- **Files touched:** hooks/guard.mjs, hooks/audit.mjs, hooks/conversation.mjs, ~/.solongate/hooks/guard.mjs, ~/.solongate/hooks/audit.mjs, ~/.solongate/hooks/conversation.mjs, ~/.claude/settings.json

- **Network endpoints:** https://api.solongate.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 94.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The explicit global setup installs hooks that intercept AI-tool events and rewrites global settings., An installed guard fetches and atomically replaces hook files from the SolonGate API., Audit and conversation hooks send redacted tool and conversation records when configured with a SolonGate API key.

- **Evidence against:** The manifest has no npm lifecycle hook, so installation alone does not mutate agent settings., Global hook setup is reached through the package's user-invoked CLI flow and prompts for or requires a SolonGate key., The remote hook update checks a SHA-256 digest before replacing a file., Network traffic is directed to the package-aligned SolonGate API and is tied to its configured service.

## Affected versions and remediation

This report applies to @solongate/proxy@0.89.16.

- Review the evidence and your use of @solongate/proxy@0.89.16 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.
