Each tool has a clearly distinct purpose targeting specific resources and actions, such as checking film availability, getting actor filmography, analyzing category performance, or retrieving customer details. There is no overlap or ambiguity between tools; for example, 'get_customer_details' and 'get_customer_rentals' serve different functions without confusion.

All tool names follow a consistent verb_noun pattern, primarily using 'get_' or 'search_' prefixes followed by descriptive nouns, with minor variations like 'check_' and 'list_' that still maintain readability. There are no deviations in style, such as mixing camelCase or snake_case, ensuring predictability across the set.

With 18 tools, the count is slightly high but reasonable for a Sakila database server covering films, customers, rentals, and analytics. It includes essential operations like search, retrieval, and analysis, though it might benefit from consolidation in areas like analytics to reduce potential complexity.

The tool set provides comprehensive coverage for the Sakila domain, including CRUD-like operations (e.g., search and get details for films and customers), rental management (e.g., overdue rentals), and advanced analytics (e.g., performance, segments, turnover). There are no obvious gaps; agents can handle full workflows from browsing to analysis without dead ends.
