Field Guide 18: a small Slack bot that celebrates design system adoption, as 22 checks. The kit scans a repo for component instances per team (or reads react-scanner reports), diffs against last week's snapshot, builds a Block Kit message validated against Slack's documented limits and posts it through an incoming webhook only when asked. It ships two fixture repos, real react-scanner output for comparison and a weekly GitHub Actions workflow.
When adoption work is invisible outside the system team, and you want teams to see each other's milestones without turning the channel into a leaderboard.
