Three tools with identical empty input schemas ({}), minimal parameter descriptions, and no output schema documentation. Tool names lack action verbs (sec_filings_today, sec_filings_8k, sec_filings_service_info are noun-heavy). Descriptions are adequate in length (194-250 chars, within baseline 34-392 range) but lack actionable guidance on when to call each tool vs. alternatives. No parameter validation, no error recovery guidance, no pagination support despite 'max 40 per call' limit. Error handling returns raw upstream errors without LLM-actionable recovery steps.

• Rename tools with action verbs: 'get_sec_filings_today', 'list_sec_8k_events', 'describe_sec_filings_service'. This helps LLMs infer intent from the name alone.
• Add explicit input schemas with optional parameters for filtering (e.g., form_type enum: ['10-K', '10-Q', '8-K'], limit: 1-40, offset: 0+). Even if the upstream API ignores them, the schema documents what the tool accepts.
• Document output schema: define the structure of each filing item (form_type, company_name, cik, filing_time_utc, edgar_url, etc.) so LLMs know what fields to extract.
• Enhance error messages with recovery guidance. E.g., 'HTTP 402 Payment Required: Ensure X402_PRIVATE_KEY is set and wallet has sufficient USDC on Base. Call sec_filings_service_info to verify pricing.'
• Add pagination support: accept optional 'limit' (1-40, default 20) and 'offset' (default 0) parameters, and return 'total_count' and 'next_offset' in responses to enable multi-page iteration.
