Server has 6 tools with basic naming and descriptions, but significant gaps in schema completeness and parameter documentation. Tool names follow verb_noun convention (get_*, maximum_pain_*), which is good. However, most tools lack explicit input schema validation in the visible code. Descriptions are present but generic (34-72 chars, below the 50-200 char LLM-optimized baseline). Parameter descriptions exist in schema but are minimal. No output schemas documented. Error handling is absent, no recovery guidance, no categorization of error types. Tools are read-only (low risk), but lack idempotency hints and confirmation patterns.

• Document output schemas for all tools. Example: get_current_stock_price should return {price: float, currency: string, timestamp: ISO8601, change_percent: float}. This enables LLMs to chain tools and extract required fields.
• Expand tool descriptions to 80-150 characters. Include WHEN to use (e.g., 'Call this to get real-time pricing before analyzing options strategies') and WHAT is returned (e.g., 'Returns current price, 52-week range, and market cap').
• Add input validation and error handling. Wrap yfinance/Tavily calls in try-except, categorize errors (invalid_symbol, api_rate_limit, network_timeout), and return actionable messages: 'Invalid symbol INVALID_TICKER. Try search_symbols() or check ticker format (e.g., AAPL, BRK.B).'
• Split selective_extract_shortlisted_urls_tavily into two tools: extract_urls_from_tavily_results (returns raw URLs) and filter_urls_by_quality (accepts URL list, returns filtered list). This enables agents to compose them as needed.
• Add parameter constraints: symbol should document format (uppercase, 1-5 chars, no spaces); expiration should validate YYYY-MM-DD format and check against actual option expiration dates; max_urls should have min/max bounds (1-50).
