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 performs undisclosed runtime telemetry: it records command usage and sends buffered events to its own API, with persistent correlation IDs. The data is limited to command metadata and the endpoint is first-party, 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:** 90.0% - **Started:** 2026-11-01T18:30:16.001Z - **Finished:** 2026-11-01T18:31:09.014Z - **Download time:** 763 ms - **Static scan time:** 3281 ms - **AI review time:** 48968 ms - **Total time:** 53013 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 records CLI command activity and later sends it to the package’s API. - **Trigger:** Running the CLI; events are buffered at command completion and may be sent when a later command starts. - **Impact:** The vendor can associate command usage and outcomes with persistent device and session identifiers; the README gives no telemetry disclosure or opt-out. - **Evidence paths:** src/index.js, src/utils/command\_telemetry.js, src/utils/analytics.js, src/constants.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-01T18:31:09.014Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Records command names and outcome metadata, stamps events with correlation IDs, then posts buffered events to \`/events\` using the package API client. - **Rationale:** The package performs undisclosed runtime telemetry: it records command usage and sends buffered events to its own API, with persistent correlation IDs. The data is limited to command metadata and the endpoint is first-party, so this warrants a warning rather than a malicious verdict. - **Files touched:** events-buffer.ndjson, device.json, session.json - **Network endpoints:** api.happyskills.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI records a \`cli.command\` event on command completion by default., Each event includes the command name, exit code, duration, CLI version, JSON mode, and sometimes an error code., Buffered events are sent to the package’s API at \`/events\` with authentication when a later command runs., The README lists commands and installation but does not disclose telemetry or provide an opt-out. - **Evidence against:** The telemetry targets the package’s own API, or the user-configured \`HAPPYSKILLS\_API\_URL\`., The command event fields do not include command arguments, file contents, hostnames, or usernames., Events are buffered locally and delivery is opportunistic; the source describes random device and session identifiers., The \`npm install\` subprocess is used only by the explicit \`self-update\` command. ## Affected versions and remediation This report applies to happyskills@3.0.0. - Review the evidence and your use of happyskills@3.0.0 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.
