25 tools with consistent naming (verb_noun pattern) and basic descriptions, but critical gaps in schema documentation and parameter descriptions. All tools have descriptions (10-50 chars, below the 50-200 char baseline for LLM optimization), and input schemas are visible in the source, but parameter descriptions are minimal or missing. No output schemas documented. Two irreversible tools (sendEvmTransaction, sendXrpTransaction) lack confirmation/dry-run patterns. Error handling not evident in source. Composition is reasonable (single responsibility per tool), but many tools lack the depth needed for production agent use.

• Expand all tool descriptions to 50-200 characters. Example: 'Get balance for a Bitcoin address' → 'Retrieve the current balance (in satoshis) for a Bitcoin address. Returns confirmed and unconfirmed amounts. Use this to check wallet status before sending transactions.'
• Document output schemas for all tools. Example for getBitcoinBalance: {balance: number (satoshis), confirmed: number, unconfirmed: number, address: string}. This enables agents to chain tools and extract required fields.
• Add enum constraints to 'network' parameter in EVM tools. Change description to: 'Network name (one of: ethereum, base, arbitrum, optimism, bsc, polygon, avalanche, berachain, sonic)' and use JSON Schema enum.
• Implement confirmation pattern for sendEvmTransaction and sendXrpTransaction. Add a 'dry_run' boolean parameter (default false) that returns estimated gas/fees without executing. Require explicit confirmation before irreversible state changes.
• Add error handling guidance to tool descriptions. Example: 'If address is invalid, returns error with format hint. If network is unreachable, error is retryable after 30 seconds. If insufficient balance, error is user-fixable.'
