43 tools with significant definition gaps. Most tools have basic descriptions (10-50 chars) but lack parameter schemas, type definitions, and output documentation. No tool annotations (readOnlyHint/destructiveHint). Parameter descriptions are minimal or absent. Error handling and recovery guidance missing. Naming is verb-noun consistent but descriptions do not explain WHEN to use each tool or dependencies between them. No pagination documented despite tools returning potentially large datasets (e.g., data_get_ohlcv, data_get_pine_tables). Output schemas not documented anywhere in source.

• Add JSON Schema input definitions to all 43 tools. Include type, description, and constraints (enum, minLength, pattern, minimum, maximum) for every parameter. Example: {"symbol": {"type": "string", "description": "Ticker symbol (e.g., AAPL, BTC/USD)", "minLength": 1, "maxLength": 20}}
• Document output schemas for all tools. Specify the structure of returned objects, field types, and which fields are required for downstream tool chaining. Example: chart_get_state should return {symbol: string, timeframe: string, indicators: [{id: string, name: string}]}
• Add tool annotations to MCP tool definitions. Use readOnlyHint for READ_ONLY tools (chart_get_state, quote_get, data_get_*), destructiveHint for DESTRUCTIVE tools (alert_delete, tab_close, watchlist_remove), and idempotentHint for idempotent WRITE tools (chart_set_symbol, chart_set_timeframe).
• Expand descriptions to 50-200 characters with WHEN/WHY guidance. Example: 'Get current numeric values from all visible indicators (RSI, MACD, Bollinger Bands, EMA, etc.). Call this after chart_get_state to extract signal values for analysis. Returns {indicator_name: value} pairs.'
• Add error handling documentation. For each tool, document expected errors (e.g., 'Invalid indicator name', 'Symbol not found'), their causes, and recovery steps. Example: 'If chart_manage_indicator returns "Indicator not found", call chart_get_state first to see available indicators.'
