## 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:** 1.14.3
- **Selected version is latest:** Yes
- **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 automatically writes package-owned extensions into the shared agent configuration, a lifecycle integration risk that warrants a warning. The inspected login flow uses the configured service and browser approval, and the postinstall script applies Pi text patches; neither establishes a concrete attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 86.0%

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 CLI writes u1s1-owned extensions into the shared Pi agent directory during runtime startup. This is a package-owned integration and no concrete attack was identified, but it creates persistent agent extension behavior.

- **Trigger:** Starting the CLI agent runtime.

- **Impact:** The extensions can add tools and event handlers to agent sessions, including sessions started through other Pi front ends sharing that directory.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-10-22T08:18:15.747Z

### AI review details

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

- **Mechanism:** The CLI creates and rewrites extension files in the agent extensions directory; Pi scans that directory for extensions.

- **Rationale:** The package automatically writes package-owned extensions into the shared agent configuration, a lifecycle integration risk that warrants a warning. The inspected login flow uses the configured service and browser approval, and the postinstall script applies Pi text patches; neither establishes a concrete attack.

- **Files touched:** dist/index.js, dist/agent-setup.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** On agent startup, the CLI writes its web tools extension into the shared agent extensions directory., The generated extension is loaded by Pi and can register tools for agent sessions., The package also runs a postinstall script that patches Pi dependency files.

- **Evidence against:** The extension is part of u1s1’s documented runtime integration and keeps its API key in an environment variable rather than the generated file., Login uses the configured service origin and polls for credentials after browser approval; inspected code did not show a separate credential recipient., The postinstall patch applies text changes to Pi dependency files.

## Affected versions and remediation

This report applies to u1s1-cli@1.14.3.

- Review the evidence and your use of u1s1-cli@1.14.3 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.
