Each tool has a clearly distinct purpose with no overlap: get_evidence focuses on source signals and provenance, get_label_values on label discovery, get_neighbors on graph traversal, get_node on direct metadata retrieval, psfk_overview on macro patterns, and search_graph on hybrid search. The descriptions reinforce these unique roles, making misselection unlikely.

All tool names follow a consistent verb_noun pattern using snake_case (e.g., get_evidence, get_label_values, get_neighbors, get_node, search_graph). The only deviation is psfk_overview, which still maintains a noun_noun structure that fits the pattern without mixing conventions, ensuring predictability and readability.

With 6 tools, this server is well-scoped for graph exploration and knowledge retrieval. Each tool serves a specific function in the workflow (e.g., discovery, traversal, search, metadata access), and none appear redundant or excessive, making the count appropriate for the domain.

The tool set covers core operations for graph-based knowledge exploration: retrieval (get_node, get_evidence), traversal (get_neighbors), search (search_graph), discovery (get_label_values), and overview (psfk_overview). A minor gap exists in update or manipulation tools (e.g., add_node, modify_relationships), but agents can likely work around this for read-only analysis.
