Two tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Descriptions are present but minimal (Spanish text, 60-90 chars). Input schemas show types but lack comprehensive parameter descriptions. No output schemas documented. Error handling absent. Idempotency key on create_note is good, but overall quality falls well below production baseline (194 char avg description, 100% param coverage in A+ tools).

• Expand tool descriptions to 150-250 chars. For create_note: 'Creates a new note with a title and content. Uses idempotency_key to prevent duplicates, calling with the same key returns the original note without creating a duplicate. Returns the created note with its ID and metadata.' For search_notes: 'Searches notes by keywords in title and content. Returns up to [limit] matching notes with snippets. Use limit and offset for pagination. Returns total count to enable multi-page retrieval.'
• Document output schemas explicitly. create_note should return {note_id: string, title: string, content: string, created_at: ISO8601, idempotency_key: string}. search_notes should return {results: [{note_id, title, snippet, created_at}], total: int, limit: int, offset: int}.
• Add parameter descriptions with constraints and examples. title: 'Note title, 2-120 characters. Whitespace is trimmed.' content: 'Note body, 1-10000 characters. Supports plain text or markdown.' query: 'Search keywords (2+ chars). Searches title and content. Partial matches supported.' limit: 'Max results per page, 1-20. Default 5. Use with offset for pagination.'
• Add error handling guidance to descriptions. E.g., 'If title exceeds 120 chars, returns 400 with message: Invalid title length. If search returns 0 results, returns empty array with total=0, suggest refining query or browsing all notes with empty query.'
• Implement pagination for search_notes. Add offset parameter (default 0) and return total_count in response. Document: 'To fetch next page, call with offset=limit. Continue until results.length < limit.'
