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 sends runtime command telemetry to its own service, including persistent session and device identifiers, without an observed disclosure or opt-out. The event fields inspected contain usage metadata rather than credentials or file contents, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-01T18:31:49.176Z - **Finished:** 2026-11-01T18:32:45.329Z - **Download time:** 505 ms - **Static scan time:** 2551 ms - **AI review time:** 53096 ms - **Total time:** 56153 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 is buffered and sent to the package’s API. - **Trigger:** Automatically when a CLI command runs; eligible commands deliver buffered events at startup. - **Impact:** The vendor can associate CLI usage and command outcomes with persistent device and session identifiers. The inspected event excludes command arguments and working directory. - **Evidence paths:** src/index.js, src/utils/command\_telemetry.js, src/utils/analytics.js, src/utils/event\_buffer.js, src/constants.js - **Review source:** ai\_review - **Reviewed:** 2026-11-01T18:32:45.329Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Records command and outcome metadata with session and device identifiers, stores events in a local NDJSON buffer, then posts them to the authenticated \`/events\` API endpoint. - **Rationale:** The package sends runtime command telemetry to its own service, including persistent session and device identifiers, without an observed disclosure or opt-out. The event fields inspected contain usage metadata rather than credentials or file contents, so this warrants a warning rather than a block. - **Files touched:** events-buffer.ndjson, src/index.js, src/utils/command\_telemetry.js, src/utils/analytics.js, src/utils/event\_buffer.js - **Network endpoints:** https://api.happyskills.ai/events ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Every resolved CLI command starts command telemetry automatically, including command name, flags, positionals and working directory in the telemetry context., The emitted \`cli.command\` event sends command name, exit code, duration, CLI version, JSON mode and optional error code; no telemetry opt-out was found in the inspected source., Buffered events are delivered to the HappySkills API at \`/events\` with authentication; events include session and device identifiers. - **Evidence against:** The transmitted command event fields are limited to usage and runtime metadata; the captured positionals, flags and working directory are written to local history rather than included in this event., The default telemetry destination is the package’s own \`https://api.happyskills.ai\` service, and delivery is buffered and best effort. ## Affected versions and remediation This report applies to happyskills@3.6.0. - Review the evidence and your use of happyskills@3.6.0 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.
