The purposes of consult_gpt5, start_conversation, and continue_conversation overlap somewhat, as all involve interacting with GPT-5. However, get_cost_* and set_cost_* are clearly distinct, and get_conversation_metadata vs summarize_conversation serve different needs.

Most tools follow a verb_noun pattern (e.g., start_conversation, get_cost_report, set_cost_limits). The exception is consult_gpt5, which embeds the object directly rather than using a generic noun, but the naming style is otherwise consistent.

With 8 tools, the server is well-scoped for managing GPT-5 conversations and costs. Each tool covers a distinct aspect of the workflow without unnecessary bloat, and the count is appropriate for the domain.

The core lifecycle of conversation management and cost control is covered, including starting, continuing, summarizing, and monitoring usage. Minor gaps include the lack of an explicit 'end_conversation' or 'delete_conversation' tool, but agents can likely work around these.
