## 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:** 1.11.1
- **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.

The package installs first-party agent extensions when the CLI starts, which warrants a warning under the agent extension setup policy. The inspected sources do not substantiate the scanner’s unofficial-gateway credential redirection claim or a concrete attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 87.0%
- **Started:** 2026-10-09T21:57:05.476Z
- **Finished:** 2026-10-09T21:58:21.098Z
- **Download time:** 760 ms
- **Static scan time:** 944 ms
- **AI review time:** 73917 ms
- **Total time:** 75622 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:** CLI startup writes first-party extensions into the agent extensions directory. This is an agent setup capability, with no confirmed hostile control change or credential exfiltration identified.

- **Trigger:** The user starts the u1s1 CLI.

- **Impact:** The agent gains u1s1-provided tools; the inspected code does not establish an attack.

- **Evidence paths:** dist/index.js, dist/agent-setup.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T21:58:21.098Z

### AI review details

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

- **Mechanism:** Startup registers web tools and writes a package-owned tools extension that uses the credential guard.

- **Rationale:** The package installs first-party agent extensions when the CLI starts, which warrants a warning under the agent extension setup policy. The inspected sources do not substantiate the scanner’s unofficial-gateway credential redirection claim or a concrete attack.

- **Network endpoints:** https://api.u1s1.io/v1

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The CLI startup registers package-owned agent extensions in the agent extensions directory., The generated tools extension uses the credential guard to keep API keys out of child processes., The default API host is api.u1s1.io, and model requests use the configured base URL., The postinstall hook runs a local patch script; no unrelated approval or agent-control mutation was identified.

- **Evidence against:** The inspected credential flow uses the package’s official API host, not the flagged unofficial gateway., The child-process guard strips credential environment variables from spawned processes.

## Affected versions and remediation

This report applies to u1s1-cli@1.11.1.

- Review the evidence and your use of u1s1-cli@1.11.1 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.
