Scored across 19 tools
Each tool has a clear, distinct purpose with explicit cross-references to avoid confusion (e.g., check_breaking_changes vs get_api_diff vs plan_upgrade; get_maintenance_status vs get_package_health). The descriptions even clarify when to use one tool over another for overlapping concepts.
All tools follow a consistent verb_noun pattern in snake_case (get_, check_, list_, register_, delete_, plan_, submit_). Even the batch variant get_package_updates_batch fits the pattern. Naming is predictable and makes tool purpose evident from the name alone.
19 tools is slightly above the typical well-scoped range, but each tool earns its place for a dependency-intelligence server covering updates, breaking changes, API diffs, compatibility, health, security, webhooks, and planning. The count feels justified rather than bloated.
The surface comprehensively covers the dependency lifecycle: checking updates, breaking changes, compatibility, migration, health, vulnerabilities, and webhook subscriptions. Minor gaps exist (e.g., no webhook update tool, no direct 'get package metadata' tool), but these are not critical dead ends.
