## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 18 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Telemetry warning (can be blocked)
- **Public report status:** Published
- **Threat category:** Telemetry
- **Selected version:** 0.21.1
- **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 CLI sends identifying machine details and command metadata to the publisher's service automatically, without a clearly disclosed consent step. The telemetry is related to the package's purpose, so this warrants a warning rather than a malicious verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 98.0%
- **Started:** 2026-11-02T12:18:34.219Z
- **Finished:** 2026-11-02T12:19:57.211Z
- **Download time:** 519 ms
- **Static scan time:** 9031 ms
- **AI review time:** 73441 ms
- **Total time:** 82992 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:** Undisclosed runtime command telemetry includes identifying machine details when no session token is available.

- **Trigger:** Runs automatically when the CLI starts.

- **Impact:** The publisher receives identifying machine information and command metadata without an explicit per-run request.

- **Evidence paths:** bin/shakers.js

- **Review source:** ai\_review

- **Reviewed:** 2026-11-02T12:19:57.211Z

### AI review details

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

- **Mechanism:** A detached worker posts command metadata to the Shakers certifications API. Without a saved session token, the payload includes the OS username and hostname.

- **Rationale:** The CLI sends identifying machine details and command metadata to the publisher's service automatically, without a clearly disclosed consent step. The telemetry is related to the package's purpose, so this warrants a warning rather than a malicious verdict.

- **Network endpoints:** https://api.certifications.shakersworks.com/api/v1/cli/command-log

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 98.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The manifest exposes bin/shakers.js as the CLI executable and declares no lifecycle scripts., Each normal CLI startup starts a detached command-audit worker., The audit sends the command, scrubbed arguments, CLI version, and timestamp; without a saved session token, it also includes the OS username and hostname., The audit posts to /cli/command-log under the default Shakers certifications API host.

- **Evidence against:** The package is an AI usage assessment CLI and MCP server, so sending limited command audit data to its own service is related to its purpose., Command arguments are passed through secret scrubbing and capped at 200 characters.

## Affected versions and remediation

This report applies to shakers-cli@0.21.1.

- Review the evidence and your use of shakers-cli@0.21.1 before allowing it. Restrict the permissions described in this report.
