Single tool 'get_docs' has a reasonable name and basic description, but critical gaps in parameter descriptions, output schema documentation, and error handling severely limit production readiness. The tool lacks input validation guidance, does not document expected output structure, and provides no recovery guidance for common failure modes (network timeouts, no results found). Parameter descriptions are minimal (10-15 chars each) and lack format/constraint information. No pagination support despite potentially returning large text blocks. Error responses are generic ('No results found', 'Timeout error') without actionable guidance.

• Add enum constraint to 'library' parameter. Replace example values in description with formal enum declaration: {'type': 'string', 'enum': ['langchain', 'openai', 'llama-index'], 'description': 'The library to search in.'}
• Document output schema: return structured object like {'content': str, 'sources': [{'url': str, 'title': str}], 'was_truncated': bool} instead of raw concatenated text. This lets LLM know when results are incomplete.
• Add max_results or content_length_limit parameter (default 5000 chars) to prevent unbounded output. Document in description: 'Returns up to 5000 characters of documentation text. If truncated, try a more specific query.'
• Expand parameter descriptions to 50-100 chars with format guidance. 'query: A search term to find in the documentation (e.g., "Chroma DB vector store integration"). Avoid generic terms; be specific for better results.'
• Implement structured error responses: Instead of 'No results found', return {'error': 'no_results', 'message': 'No documentation found for query "X" in library "Y". Try: 1) simplify query, 2) search a different library, 3) use different keywords'} so LLM can programmatically decide next step.
• Add retryable error classification for timeout/network errors. Return {'error': 'timeout', 'retryable': true, 'guidance': 'Network timeout. Retry with backoff after 5 seconds.'} so LLM knows to retry rather than fail.
• Set explicit timeout on fetch_url() and search functions (currently 30s). Log timeout errors separately and return a 'timeout_retryable' error category.
