Two tools with minimal documentation. get_current_time has no input schema (empty object) and a 31-char description. get_protein_attributes_from_uniprot has a proper input schema but a 127-char description that embeds example values (P06493), violating the pattern:tool-description rule against examples in descriptions. Neither tool has output schemas documented. No error handling, no parameter validation guidance, no recovery paths. The resource (list_sparqlets) is present but not a tool. Overall definition quality is poor.

• Add explicit output schema to both tools. For get_current_time, document: {"type": "string", "description": "ISO 8601 timestamp"}. For get_protein_attributes_from_uniprot, document the JSON structure returned by the UniProt API (e.g. fields like protein_name, organism, sequence_length).
• Remove example 'P06493' from get_protein_attributes_from_uniprot description. Instead, add a regex pattern constraint to the uniprot_protein_id parameter: {"type": "string", "pattern": "^[A-Z0-9]+$", "description": "UniProt Protein ID (uppercase alphanumeric, e.g. format P12345)"}.
• Add error handling to get_protein_attributes_from_uniprot. Wrap requests.get() in try-except. Return actionable errors: 'Protein P06493 not found in UniProt. Verify the ID is correct (format: uppercase alphanumeric).' or 'UniProt API unavailable. Retry in 30 seconds.'
• Expand get_current_time description from 31 chars to 50-100 chars. Include when to use it: 'Returns the current date and time in ISO 8601 format. Use this to timestamp events, check elapsed time, or provide context for time-sensitive operations.'
• Add parameter description to uniprot_protein_id: 'UniProt Protein ID in uppercase alphanumeric format (e.g. P06493 for human insulin receptor). Call with a valid UniProt accession number to retrieve protein attributes.'
