## 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:** 1.9.1
- **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.

This is a real lifecycle and agent-extension risk, but the inspected mutations are limited to declared dependencies and the package-owned u1s1 agent directory. The source does not establish malicious exfiltration, destructive behavior, or broad foreign agent control-surface mutation.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-09-12T10:53:25.556Z

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:** Installing the package patches its Pi dependencies. Running the CLI writes u1s1-owned Pi extensions and may download helper binaries or update itself.

- **Trigger:** npm installation, then execution of the u1s1 command

- **Impact:** Changes the bundled agent runtime and creates persistent executable extension files; downloaded helpers and updates expand supply-chain exposure.

- **Evidence paths:** package.json, scripts/patch-pi.js, dist/index.js, dist/agent-setup.js, dist/search-tools.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T10:54:32.499Z

### AI review details

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

- **Mechanism:** lifecycle dependency patching and runtime agent-extension generation

- **Rationale:** This is a real lifecycle and agent-extension risk, but the inspected mutations are limited to declared dependencies and the package-owned u1s1 agent directory. The source does not establish malicious exfiltration, destructive behavior, or broad foreign agent control-surface mutation.

- **Files touched:** node\_modules/@earendil-works/pi-coding-agent/dist/modes/interactive/interactive-mode.js, node\_modules/@earendil-works/pi-coding-agent/dist/core/slash-commands.js, node\_modules/@earendil-works/pi-tui/dist/tui-main-screen.js, ~/.u1s1/agent/extensions/u1s1-tools.js, ~/.u1s1/agent/bin/fd, ~/.u1s1/agent/bin/rg

- **Network endpoints:** https://api.u1s1.io/v1, https://registry.npmjs.org/u1s1-cli/latest

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The install lifecycle runs a script that rewrites files in the bundled Pi dependencies., The CLI automatically creates and rewrites executable Pi extension modules under its agent directory., Startup downloads missing search-tool archives and installs their extracted binaries., The CLI can automatically install a newer package release after an interactive session ends.

- **Evidence against:** The install patch targets only the package's declared Pi dependencies and consists of UI and translation replacements., The runtime extensions are written under the package-owned u1s1 agent directory, not a general agent configuration location., No source path inspected sends harvested environment values or local files to an unrelated endpoint.

## Affected versions and remediation

This report applies to u1s1-cli@1.9.1.

- Review the evidence and your use of u1s1-cli@1.9.1 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.
