Get Gene Record

get_gene
Read-onlyIdempotent

Retrieve the complete HGNC record for any gene using an HGNC ID, current or previous symbol, or alias. Includes name, status, location, cross-references, and more.

Instructions

Return the full HGNC record for a gene, resolved from an HGNC id, current symbol, previous symbol, or alias. Includes name, status, locus group/type, location, aliases/previous symbols, gene groups, and all cross-references. response_mode controls verbosity (compact drops dates/provenance; minimal keeps identity + anchor ids). Signature: get_gene(query, response_mode=).

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint etc. Description adds what the record includes (name, status, etc.) and explains response_mode effect, going beyond annotations without contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences front-loading main purpose then detailing record contents and parameter options. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given simple tool with annotations and output schema, description adequately covers functionality, parameters, and return content.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%. Description adds meaning to response_mode by explaining verbosity levels (compact drops dates, minimal keeps identity), and clarifies query input types.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states 'Return the full HGNC record for a gene' with specific input types (HGNC id, symbol, previous symbol, alias), distinguishing it from siblings like search_genes and resolve_symbol.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies use when needing full record for known identifier, but lacks explicit 'when to use' or 'when not to use' guidance. Siblings exist for searching or resolving but no direct comparison.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
