Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 19 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:** 3.12.6 - **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 default startup ping is undisclosed in the package documentation, so it meets the warning-level rule for runtime telemetry. Its payload is limited to an install/update event, version, platform, and architecture, and I found no evidence of malicious collection or install-hook contact. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-30T23:28:18.216Z - **Finished:** 2026-10-30T23:29:13.448Z - **Download time:** 520 ms - **Static scan time:** 6375 ms - **AI review time:** 48336 ms - **Total time:** 55232 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, default-on install/update telemetry on CLI startup. - **Trigger:** Running a normal CLI command when no marker exists or the stored version differs; ARCHYMEDES\_TELEMETRY, DO\_NOT\_TRACK, CI, or NODE\_ENV=test can suppress it. - **Impact:** The service can count installs and updates and learn the CLI version and platform. No project data or credentials are included in this cue. - **Evidence paths:** dist/archymedes-main.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-30T23:29:13.448Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Sends an install/update event, CLI version, OS platform, and architecture to the package service, then stores the version marker. - **Rationale:** The default startup ping is undisclosed in the package documentation, so it meets the warning-level rule for runtime telemetry. Its payload is limited to an install/update event, version, platform, and architecture, and I found no evidence of malicious collection or install-hook contact. - **Files touched:** settingsDirectory(environment)/installed.json - **Network endpoints:** https://archymedes.xyz/api/v1/count/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Ordinary CLI startup calls sendInstallCue without waiting for a user telemetry choice., The cue contains only an install/update event, CLI version, OS platform, and architecture., The cue is POSTed to https://archymedes.xyz/api/v1/count/ by default; code provides environment-variable opt-outs., The only declared lifecycle script is prepublishOnly, which runs the build. - **Evidence against:** The telemetry does not include project data, credentials, hostnames, or command output., The cue is sent only when the stored version differs, so it is limited to an initial run or version update. ## Affected versions and remediation This report applies to @archymedes/friday@3.12.6. - Review the evidence and your use of @archymedes/friday@3.12.6 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.
