Each tool has a distinct role: list_packages browses the catalog, recommend_package maps a task to a package, get_snippet returns details for a known package, and check_config scans user code. The only real overlap is that recommend_package also returns install lines and quickstarts, so an agent might sometimes skip get_snippet, but the descriptions make the task-driven vs package-specific split clear.

All four tools follow a clean verb_noun snake_case pattern (recommend_package, get_snippet, check_config, list_packages). No mixed conventions or vague verbs.

Four tools is slightly lean but each maps to a distinct step in the workflow: discover, choose, inspect, and audit. Nothing feels redundant or missing for a package catalog server.

The surface covers the key lifecycle: listing packages, recommending one for a task, retrieving its quickstart, and auditing existing code for vulnerable algorithms. Gaps are minor, e.g. no dedicated search-by-keyword or version/detail lookup beyond what list_packages and get_snippet provide.
