Coordinates atomic changes across multiple repositories by tracking dependency graphs, managing linked PRs, and detecting breaking changes before they propagate. You define repo relationships in a simple YAML file, then the skill helps you identify which downstream services break when you modify an API contract, create coordinated PR sets that merge in the right order, and generally avoid the chaos of microservices sprawl. The breaking change detection actually scans dependent repos for usage patterns rather than just hoping for the best. Honestly most useful if you're already dealing with the pain of features that span repo boundaries and need something more structured than Slack messages and spreadsheets.
