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 usage telemetry automatically on exit and reports project names after builds, with no visible disclosure or opt-out in the inspected entry point and help. The token is used with the package’s own service, and no unrelated secret collection was found, 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:** 89.0% - **Started:** 2026-11-02T21:45:53.486Z - **Finished:** 2026-11-02T21:46:31.406Z - **Download time:** 510 ms - **Static scan time:** 227 ms - **AI review time:** 37182 ms - **Total time:** 37920 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 sends CLI activity and build details to the Dasyl API when a saved API token exists. - **Trigger:** The CLI calls process.exit; the telemetry sender runs detached. Build tracking runs after project generation. - **Impact:** The Dasyl service receives command and build activity associated with the authenticated account without a documented opt-out. - **Evidence paths:** bin/index.js, lib/send-telemetry.js, lib/telemetry.js, lib/commands/login.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T21:46:31.406Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The sender reads ~/.dasyl/config.json and posts usage fields with the saved Bearer token. Build tracking posts the project name and framework. - **Rationale:** The CLI sends usage telemetry automatically on exit and reports project names after builds, with no visible disclosure or opt-out in the inspected entry point and help. The token is used with the package’s own service, and no unrelated secret collection was found, so this warrants a warning rather than a malicious verdict. - **Files touched:** ~/.dasyl/config.json - **Network endpoints:** https://dasyl-ten.vercel.app/api/telemetry/log, https://dasyl-ten.vercel.app/api/telemetry/track, process.env.DASYL\_API\_URL (configurable API base URL) ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI replaces process.exit and launches a detached telemetry sender on every exit, including help and error exits., When a Dasyl API token is saved, the sender posts the command, duration, status, OS, Node version, and CLI version without an opt-out., Build tracking also sends the chosen project name and framework to the Dasyl API using the saved token. - **Evidence against:** The token is obtained through the package’s Dasyl login flow and sent to the Dasyl service for authentication and usage tracking., The package’s project generation, dependency installation, and optional Git setup fit its stated CLI scaffolding purpose., No automatic collection or transmission of unrelated credentials or local files was identified. ## Affected versions and remediation This report applies to dasyl@2.1.0. - Review the evidence and your use of dasyl@2.1.0 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. ## Public findings ### 1.
