ValueCell exposes 3 tools for news and financial data retrieval. All tools have descriptions and basic input schemas, but quality is inconsistent. Tool names follow verb_noun convention (web_search, get_breaking_news, get_financial_news), which is positive. However, descriptions are surface-level and lack context about when to use each tool vs. alternatives. Parameter descriptions are sparse or missing. Output schemas are not documented anywhere in the provided source. Error handling guidance is absent. The server is built on agno framework with HTTP transport, but the tool definitions lack the depth expected for production agent interactions.

• Add explicit output schema documentation for each tool. Example for web_search: '{"results": [{"title": string, "url": string, "snippet": string, "source": string}], "total_results": number, "search_time_ms": number}'. Document what fields the LLM can expect and which are safe for downstream reference.
• Expand web_search description to ~150 chars with clear selection criteria: 'Search the public web for current information. Call this for general queries, news, or recent events. For financial data, prefer get_financial_news. For breaking news alerts, prefer get_breaking_news.' This disambiguates when to use each tool.
• Add meaningful description to get_breaking_news: 'Fetch urgent, breaking news headlines and alerts. No parameters required, returns the most recent critical news across all categories. Use this when user asks for breaking news, urgent updates, or time-sensitive alerts.'
• For get_financial_news, document parameter behavior: 'Optional ticker (e.g. AAPL) returns company-specific market news. Optional sector (e.g. technology, finance) returns sector-wide news. If both omitted, returns general financial market news. Cannot provide both ticker and sector in same call.'
• Add error handling guidance to all tools. Example: 'If search returns no results, try a simpler query or ask user for more context. If API timeout occurs, retry once after 2 seconds. If quota exceeded, inform user that search is temporarily unavailable.'
• Consider adding pagination parameters (limit: 1-50 default 10, offset: 0+) to web_search and get_breaking_news to bound result size and prevent context window explosion.
