Scored across 10 tools
Each tool has a clearly distinct domain (e.g., Asset vs Compression, Transaction vs Wallet), and their descriptions explicitly state what to use and what not to use, eliminating ambiguity.
Nine tools follow the 'helius<Category>' pattern (e.g., heliusAccount, heliusChain), but 'expandResult' deviates, breaking full consistency. Casing is uniform (camelCase).
With 10 tools, the set is well-scoped for a comprehensive Solana blockchain API, covering accounts, assets, chain state, compression, transactions, wallets, streaming, writes, and knowledge.
The tool surface is remarkably complete for the domain: account setup, asset queries, raw chain state, compressed state, transaction history, wallet portfolios, webhooks, writes, and documentation – no obvious gaps for common operations.
