uniprot-link demonstrates solid definition quality with consistent naming patterns (verb_noun: find_proteins, get_protein, etc.), comprehensive parameter schemas with types and descriptions, and clear tool purposes. All 15 tools follow action-verb conventions. However, descriptions are often terse (many under 100 chars), output schemas are not explicitly documented in the source, and error handling guidance is minimal. Parameter descriptions are present but lack constraint details (ranges, formats, enums). The server targets a specialized domain (UniProt research) with well-scoped, read-only operations, which reduces complexity but also limits composition patterns.

• Document output schemas for all tools. Add a 'Returns' section to each tool description specifying field names, types, and structure. Example: 'Returns: {accession: string, name: string, organism: string, features: [{type: string, start: int, end: int}]}'.
• Expand parameter descriptions to include constraints. For taxon_id, add 'positive integer, e.g., 9606 for Homo sapiens'. For accession, add 'UniProt accession format: 1-6 alphanumeric characters, optionally followed by -N for isoforms (e.g., P05067-2)'.
• Enhance tool descriptions to 100-200 characters. Add context: 'Find proteins by gene name, organism, or keyword. Use this to discover protein accessions before calling get_protein for details. Returns up to [limit] matches sorted by relevance.'
• Add error handling guidance. For get_protein, add: 'If accession not found, returns 404. Try find_proteins() with a gene name or keyword to locate the correct accession.'
• Document pagination for list tools. For find_proteins, add: 'Results are limited to [limit] entries. To fetch more, use the offset parameter (not currently exposed; consider adding). Total count is returned to indicate if more results exist.'
