    Disambiguation5/5

    Each tool targets a distinct aspect of Zcash shielded operations: creating addresses, checking balance, getting price, viewing transactions, and sending payments. No overlap.

    All tools follow a consistent verb_noun pattern with underscores (e.g., create_shielded_address, get_balance). Naming is uniform and predictable.

    Tool Count5/5

    Five tools is appropriate for a focused Zcash private transaction server. Each tool serves a clear purpose without unnecessary bloat or deficiency.

    Completeness4/5

    Covers the core shielded workflow: address creation, balance, send, and history. Minor gap: no tool for receiving payments or viewing public balances, but scope is well-defined for shielded operations.
