Single tool with adequate naming (verb_noun pattern) but significant gaps in description depth and parameter documentation. Tool description is 108 chars (within 10-1024 range) but lacks WHEN/WHY context. Input schema present with type and description, but output schema is complex nested structure without field-level descriptions. No error handling guidance, no pagination despite potential for large result sets, no rate limiting or timeout documentation. Missing security considerations for external API calls.

• Add field-level descriptions to GlycanInfo model: describe what 'position' means (amino acid position?), what 'glytoucan_ids' represents, what 'source' links to. Each nested field needs 20-50 char explanation.
• Document error scenarios and recovery paths: 'If UniProt ID not found, try searching with partial protein name. If API timeout occurs, retry after 5 seconds. If API returns 429, wait 60 seconds.'
• Add limit parameter (default 20, max 100) and document result capping. Return total_count and next_cursor for pagination support.
• Expand tool description to 150-250 chars: explain when to use (e.g., 'Use this to find glycosylation sites on a protein before analyzing post-translational modifications'), prerequisites (valid UniProt ID), and what the results enable.
• Remove example value from parameter description. Replace 'Example: Q9NR99' with format constraint: 'UniProt ID format: uppercase letters and digits, 6-10 characters (e.g., P12345 or Q9NR99 pattern)' or use enum if only specific IDs are valid.
