Single tool (web_search) with basic implementation. Tool has a description and a simple input schema, but lacks critical details expected in production tools. The description is present but generic (54 chars), and the parameter description is minimal. Output schema is not documented. Error handling returns a generic dict with an 'error' key but provides no recovery guidance. The tool follows basic naming conventions (verb_noun), but lacks the richness needed for reliable agent planning. No output structure is defined, forcing LLMs to infer what fields are returned. The implementation is functional but falls short of production-grade tool definition quality.

• Expand tool description to 120-180 chars explaining: (1) what search_web does, (2) when to use it (e.g., 'for current events, specific facts, or latest product info'), (3) what it returns (list of results with title, url, snippet). Example: 'Search the public web for current information, facts, and recent events. Returns up to 10 results per query, each with title, URL, snippet, and relevance score. Use when you need facts not in your training data.'
• Add parameter constraints to 'query': specify max length (e.g. 200 chars), allowed character types, and format hints. Example description: 'A natural-language search query (1-200 chars). Supports keywords, phrases, Boolean operators (AND, OR, NOT). Examples: "latest AI news", "Python 3.12 release", "remote jobs Canada".'
• Document the return structure explicitly in the tool schema. Add a structured output type indicating each result has: title (string), url (string), snippet (string), score (float 0-1). Include a note in the description: 'Each result includes title, URL, snippet excerpt, and relevance score (0-1).'
• Improve error handling to return structured, actionable errors: (1) if Tavily API key is invalid, return {'error': 'unauthorized', 'error_description': 'API key invalid or expired. Contact your admin.', 'retryable': false}; (2) if rate limited, return {'error': 'rate_limited', 'error_description': 'Search rate limit exceeded. Retry after 60 seconds.', 'retryable': true, 'retry_after_seconds': 60}; (3) if timeout, return {'error': 'timeout', 'error_description': 'Search timed out after 30s. Try a simpler query or retry.', 'retryable': true}.
