Critical gaps across all dimensions. Tool descriptions are present but generic (avg ~40 chars, well below 194-char baseline). Input schemas exist but lack parameter descriptions entirely, every parameter is undescribed, violating the 100% A+ baseline. No output schemas documented. No error handling guidance. Irreversible operations (buy, sell, close_position) lack confirmation patterns or dry-run support. No tool annotations (readOnlyHint/destructiveHint). Naming is verb-prefixed but descriptions fail to explain WHEN to use each tool or what it returns. Security concern: wallet/private key handling visible in code but no mention of secret injection pattern in tool definitions.

• Add parameter descriptions to all 13 tools. For numeric params (solAmount, slippageBps, limit), specify min/max ranges and units. E.g., 'slippageBps: Slippage tolerance in basis points (0-10000, where 100 = 1%)'.
• Document output schemas for all tools. Define field names, types, and whether results are paginated. E.g., solana_get_balance should return {balance: number, unit: 'lamports'|'SOL', last_updated: ISO8601}.
• Add confirmation/dry-run pattern to solana_buy, solana_sell, solana_close_position. Implement a 'dry_run' boolean parameter or a separate 'preview_trade' tool that returns estimated output without executing.
• Add tool annotations: mark solana_buy, solana_sell, solana_close_position with destructiveHint=true; mark all read-only tools with readOnlyHint=true; mark idempotent tools with idempotentHint=true.
• Expand tool descriptions to 100-200 chars. Include WHEN to use (e.g., 'Call this before trading to verify RPC connectivity'), WHAT it returns, and any prerequisites. E.g., 'Get current SOL/USD price from Helius RPC. Returns real-time price updated every 5 seconds. Call this before solana_buy to estimate entry cost.'
