## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 17 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 1.0.0
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Static inspection found a narrow dependency UI patch and package-aligned update/configuration behavior, but no concrete malicious behavior. The package does not runtime-depend on itself or mutate a foreign broad AI-agent control surface.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 84.0%
- **Started:** 2026-09-29T08:47:47.953Z

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:** No confirmed attack surface was identified. The install hook makes a narrow UI patch to its declared dependency, and runtime settings remain under the package-owned agent directory.

- **Trigger:** Installation runs the declared postinstall hook; invoking the CLI can check for updates or configure its own agent settings.

- **Impact:** No credential harvesting, unrelated exfiltration, remote payload execution, broad agent-control mutation, or destructive behavior was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-29T08:51:00.911Z

### AI review details

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

- **Mechanism:** The hook replaces known UI strings in one Pi component. The updater queries this package's npm registry endpoint, while shell setup writes a shell path to package-owned settings.

- **Rationale:** Static inspection found a narrow dependency UI patch and package-aligned update/configuration behavior, but no concrete malicious behavior. The package does not runtime-depend on itself or mutate a foreign broad AI-agent control surface.

- **Network endpoints:** https://registry.npmjs.org/u1s1-cli/latest

### Review decision

- **Verdict:** Clean

- **Confidence:** 84.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package declares one postinstall hook and no self-dependency., The postinstall code targets a specific bundled Pi interactive UI component and is idempotent., Shell configuration is written only to the package-owned agent settings location., Update checks use the npm registry for this package and can be disabled through settings.

## Affected versions and remediation

- Review the evidence and your use of u1s1-cli@1.0.0 before allowing it. Restrict the permissions described in this report.
