Two tools with minimal quality. Tool 1 ('Add or Update Note') has a vague name combining two actions (add AND update), lacks clarity on when each applies, and has no output schema documentation. Tool 2 ('search_notes') uses a cryptic parameter name 'ss' instead of 'search_term' or 'query'. Both descriptions are under 100 chars and lack context on when to use them. Parameter descriptions are minimal (10-20 chars). No error handling guidance, errors return raw exception messages. No pagination support for search results. No input validation or constraints documented.

• Split 'Add or Update Note' into two tools: 'create_note(name, content)' and 'update_note(name, content)'. Document when each is appropriate.
• Rename parameter 'ss' to 'search_term' and expand description to 50+ chars: 'The search term to find notes by title or content. Supports partial matches.'
• Add explicit output schema documentation: 'Returns a list of matching notes, each with id, title, snippet (first 200 chars), and url. Limited to 20 results; use offset/limit for pagination.'
• Implement structured error responses with recovery hints. E.g., if note exists, suggest update_note(). If wiki is down, suggest retry with backoff.
• Add limit and offset parameters to search_notes. Default limit=20, max=100. Return total_count so agent knows if more results exist.
