## 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:** 1.11.0
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The package does not meet the combined lifecycle self-dependency or concrete malicious-behavior threshold. Its postinstall mutation of potentially hoisted AI-agent dependency files is nevertheless an unresolved, non-consensual lifecycle risk.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 89.0%
- **Started:** 2026-09-15T06:16:16.741Z
- **Finished:** 2026-09-15T06:17:25.659Z
- **Download time:** 508 ms
- **Static scan time:** 890 ms
- **AI review time:** 67519 ms
- **Total time:** 68918 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:** Installing the package automatically rewrites files in the Pi coding-agent dependency, potentially including a hoisted shared copy. When the CLI is run, it also creates extensions and a prompt append file in its own agent directory.

- **Trigger:** npm installation triggers postinstall; running the u1s1 CLI triggers agent setup.

- **Impact:** The install changes an AI-agent dependency without an explicit command, and the runtime configuration can alter agent presentation and capabilities.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-15T06:17:25.659Z

### AI review details

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

- **Mechanism:** Automatic dependency patching and first-party agent extension setup.

- **Rationale:** The package does not meet the combined lifecycle self-dependency or concrete malicious-behavior threshold. Its postinstall mutation of potentially hoisted AI-agent dependency files is nevertheless an unresolved, non-consensual lifecycle risk.

- **Files touched:** scripts/patch-pi.js, 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, ~/.u1s1/agent/APPEND\_SYSTEM.md, ~/.u1s1/agent/extensions/

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 89.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Low

- **Evidence for warning:** The automatic postinstall hook runs a script that patches another package's installed code., The patch locator walks upward through parent directories, so it can modify hoisted copies outside this package's own directory., The hook overwrites Pi coding-agent UI and extension-handling files, including suppressing extension stack output unless an environment flag is set., Normal CLI startup writes and loads several extensions and a system-prompt append file in its agent directory.

- **Evidence against:** There is no runtime dependency on u1s1-cli itself., The reviewed network and binary-download behavior is invoked during CLI use and is aligned with its agent/search features., The code explicitly strips its own secret environment variables before child processes are launched., No source evidence shows credential exfiltration, destructive commands, or an opaque remote payload in the install hook.

## Affected versions and remediation

This report applies to u1s1-cli@1.11.0.

- Review the evidence and your use of u1s1-cli@1.11.0 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.
