Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 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:** 1.0.4 - **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’s core behavior matches its linter purpose, and the flagged license-key traffic goes to Polar or the vendor’s rule service for the package’s own licensing and rules. However, interactive use sends undisclosed runtime telemetry by default, so this merits a warning under the telemetry rule. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-31T14:12:29.032Z - **Finished:** 2026-10-31T14:13:21.136Z - **Download time:** 764 ms - **Static scan time:** 64 ms - **AI review time:** 51276 ms - **Total time:** 52104 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 telemetry reports CLI use and paywall events to the vendor; no credential exfiltration or other attack was identified. - **Trigger:** A user runs a free scan in an interactive terminal, or reaches a missing/invalid-license path in an interactive terminal or MCP session. - **Impact:** The vendor learns that the tool was used or that a license check failed. The inspected event payloads do not include project or credential data; the telemetry is not disclosed in the README. - **Evidence paths:** cli.js, license.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-10-31T14:13:21.136Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends a small event to getreadystack.com containing the tool slug, source, and reason. DO\_NOT\_TRACK=1, READYSTACK\_NO\_TELEMETRY, and CI suppress these events. - **Rationale:** The package’s core behavior matches its linter purpose, and the flagged license-key traffic goes to Polar or the vendor’s rule service for the package’s own licensing and rules. However, interactive use sends undisclosed runtime telemetry by default, so this merits a warning under the telemetry rule. - **Files touched:** ~/.config/readystack/red-doc-en18031-lint.json (or READYSTACK\_HOME/red-doc-en18031-lint.json) - **Network endpoints:** getreadystack.com/api/ev, api.polar.sh/v1/customer-portal/license-keys/validate, getreadystack.com/api/rules/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** An interactive free CLI run automatically sends a usage event to getreadystack.com after scanning., The usage event contains only the tool slug, CLI source, and a fixed reason; it skips sending when telemetry opt-out variables or CI are set., Missing or invalid license checks can also send a paywall event with the tool slug, source, and reason., The license key is sent to api.polar.sh for validation, and a saved key is sent to getreadystack.com to retrieve this tool's rules. - **Evidence against:** The package is a CLI linter whose manifest points to cli.js, consistent with its stated purpose., Telemetry is limited to tool-use and paywall metadata; inspected payloads do not include hostnames, usernames, paths, file contents, or credentials., The usage telemetry has opt-out checks and is limited to interactive terminal or MCP use., The README describes free linting and paid folder sweeps, while the inspected source contains no install lifecycle scripts. ## Affected versions and remediation This report applies to @readystack/red-doc-en18031-lint@1.0.4. - Review the evidence and your use of @readystack/red-doc-en18031-lint@1.0.4 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. ## Public findings ### 1.
