Critical gaps across all dimensions. Tool descriptions are present but often generic or overly technical (e.g., 'predict_crypto' mixes use cases with parameter docs). Input schemas visible for most tools but lack proper type definitions and constraints. Parameters like 'symbol' and 'coin' accept free-form strings without enums despite known valid values (BTC, ETH, etc.). No output schemas documented. Error handling absent. Security concerns: no mention of API key injection or rate limiting. Tool composition issues: 'analyze_stock', 'save_analysis_report', and 'generate_stock_charts' should be one cohesive workflow, not three separate tools. Naming is verb-based but some tools are vague ('analyze_*' vs 'predict_*' distinction unclear).

• Document output schema for every tool. Example for 'predict_crypto': {direction: 'up'|'down'|'neutral', confidence: 0-100, price_target: number, timestamp: ISO8601, risk_level: 'low'|'medium'|'high'}. Use JSON Schema format.
• Add enum constraints to all symbol/coin parameters. Replace free-form 'symbol' with explicit enum: ['AAPL', '000001.SZ', '600519.SH', ...] for stock tools; 'coin' already has enum in predict_crypto, apply same pattern to analyze_commodity.
• Merge 'analyze_stock' + 'save_analysis_report' + 'generate_stock_charts' into a single 'analyze_stock_complete' tool with optional output_path and output_dir parameters. Return all three outputs (analysis, report_path, chart_paths) in one response.
• Add error recovery guidance to descriptions. Example: 'If symbol not found, try search_symbols() with a partial name.' Include retryable vs fatal error classification in tool docs.
• Implement pagination for list_tools and compare_stocks. Add limit (default 20, max 100) and offset/cursor parameters. Return total_count and next_cursor in response.
