Scored across 5 tools
Disambiguation5/5
Each tool has a distinct purpose: preflight cost estimation, schema introspection, actual query execution, subgraph search, and wallet status. No overlap or ambiguity.
Naming Consistency4/5
Most tools follow a clear verb_noun pattern (get_payment_info, get_subgraph_schema, query_subgraph, search_subgraphs). wallet_status deviates slightly but remains clear and consistent in style.
Tool Count5/5
Five tools cover the essential operations for a payment-based subgraph query service: preflight, schema, query, search, and wallet management. The count is well-scoped without unnecessary tools.
Completeness4/5
The tool set covers the core workflow: discovery, schema exploration, cost estimation, querying, and wallet status. A minor gap is the lack of a direct funding tool, but the query tool handles insufficient balance by returning funding instructions.
