Each tool has a clearly distinct purpose: check_territory verifies market eligibility, compare_plans and compare_this_house rank plans but differ by input (zip vs. address), and explain_plan provides detailed receipt for a single plan. The descriptions clarify when to use compare_this_house over compare_plans, eliminating ambiguity.

All tool names follow a consistent verb_noun pattern using snake_case: check_territory, compare_plans, compare_this_house, explain_plan. The two compare tools share the same verb, and all names are descriptive and predictable.

With 4 tools, the server is tightly scoped to the domain of Texas electricity plan comparison. Each tool serves a distinct step in the user workflow—eligibility check, comparison, address-specific comparison, and plan explanation—so the count feels well-balanced and not excessive.

The tool surface covers the full lifecycle required for plan comparison: check market eligibility, compare plans by zip or address, and get detailed cost breakdowns. There are no obvious dead ends—users can flow from territory check to plan ranking to plan details without missing operations. The server's purpose is fully realized.
