Single tool with clear naming (verb_noun: find_relevant_doc_pages) and complete JSON Schema. Description is adequate (145 chars, within 10-1024 range). All three parameters have type definitions and descriptions. However, output schema is undocumented, LLMs cannot predict the response structure. Error handling returns text-only responses without recovery guidance or error classification. No tool annotations (readOnlyHint, idempotentHint). Parameter descriptions lack format constraints (e.g., max_pages_to_discover says '1-50' but no enum/pattern in schema). Missing guidance on when to use this tool vs alternatives.

• Document the output schema explicitly. Define whether the response is {urls: string[], metadata?: object} or {results: [{url: string, relevance_score?: number}]} and include this in the tool definition or a separate schema reference.
• Add tool annotations to the FIND_RELEVANT_DOC_PAGES_TOOL object: readOnlyHint: true (safe to retry), idempotentHint: true (same inputs = same outputs). This signals to LLMs that the tool is safe for retry logic.
• Enhance error messages with recovery guidance. Instead of 'Failed to discover pages from {root_url}', return 'Failed to discover pages from {root_url}. Verify the URL is accessible and contains valid documentation links. Try a different root_url or increase max_pages_to_discover.'
• Add JSON Schema constraints for max_pages_to_discover: use minimum: 1, maximum: 50 in the schema (not just description). This is machine-parseable and prevents LLM hallucination.
• Expand tool description to include prerequisites and use cases: 'Discovers and filters documentation pages. Use this when you need to find relevant docs from a website. Requires root_url to be a valid documentation site with internal links. Returns a list of relevant page URLs sorted by relevance.'
