The tools are mostly distinct: search_solutions and get_solution are clearly search vs. fetch, while health_check is administrative. diagnose_symptoms overlaps somewhat with search_solutions as both return playbook recommendations, but the descriptions clarify the different input modes (keyword search vs. symptom mapping).

All tool names follow a consistent snake_case verb_noun pattern: search_solutions, get_solution, diagnose_symptoms, health_check. No mixed conventions or vague verbs.

Four tools is well-scoped for a focused playbook server. Each tool has a clear purpose and the count feels neither sparse nor bloated.

The core read-only workflows are covered: search, fetch by id, and symptom-based diagnosis. A minor gap is the absence of a list_all_playbooks tool, but search_solutions likely covers exploration. No create/update/delete is expected for this offline reference server.
