Field notes
The CLI is invoked with `npx harbyn scan`; the homepage says it matches repository call sites to vendor changes and reports file and line, effective date, next step, and source announcement. Its agent prompt requires Node.js 22+, tells agents to scan nested repositories separately, and says a failed feed signature must not be mistaken for an empty result.
