A3.5/5.0

Scored across 39 tools

Disambiguation2/5

Several clusters of tools have near-identical purposes: list_available_plans / search_plans / compare_plans / recommend_plan / plan_trip / get_plan_details all answer 'which plan should I get', and get_country_fact_sheet / list_country_networks / check_coverage / get_travel_data_checklist overlap heavily on country facts. Likewise estimate_data_usage / calculate_data_budget / forecast_data_threshold all deal with data sizing. Descriptions try hard to carve out boundaries ('matches the free website tool'), but an agent must read several paragraphs to pick correctly.

Naming Consistency4/5

Names are uniformly snake_case with a leading verb (check_, get_, list_, find_, plan_, setup_, calculate_, lookup_, validate_), which makes the surface predictable. A few names are awkward or compound, such as check_activation_details_format and get_travel_data_checklist, but the convention itself never breaks.

Tool Count2/5

39 tools is heavy for this scope, and many are composite wrappers (plan_trip, get_travel_data_checklist, recommend_plan) that duplicate primitives already exposed individually. Plus one-off utilities like get_public_ip, grade_connection_quality, format_international_number, and measure_latency feel tangential to the core eSIM planning job.

Completeness3/5

Coverage of planning, device checks, installation, and troubleshooting is genuinely broad. However, the post-purchase lifecycle is a notable gap: validate_order_draft is explicitly a dry run, and there is no tool to place an order, view an existing order/eSIM, retrieve activation codes, top up, or request a reissue — those dead ends are pushed to 'contact support'. The server also has no account/balance access at all, which limits real-trip support.
