biothings_get_gene

Fetch detailed gene information using an Entrez or Ensembl ID. Retrieve single gene annotations with specific fields and species filters.

Instructions

Fetch a specific gene by Entrez or Ensembl ID.

    Retrieves detailed information for a **single, specific gene** using its exact known identifier.
    **This is the preferred tool over `query_genes` for fetching a specific gene when you already know 
    its standard ID (Entrez or Ensembl) and don't need complex search filters.**
    
    **Supported Identifiers:**
    - Entrez Gene ID: e.g., `1017`
    - Ensembl Gene ID: e.g., `ENSG00000123374`

Behavior4/5

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

No annotations provided, but the description discloses that it retrieves detailed info for a single gene. It lacks details on error handling or rate limits, but the non-destructive read-only nature is clear from the description.

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

Conciseness4/5

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

Description is concise, uses bullet points and bold for readability. It front-loads the purpose and is not overly verbose. Minor room for improvement by explaining additional parameters concisely.

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

Completeness3/5

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

Output schema exists, so return values are covered. However, the description lacks explanation for three of four parameters, which reduces completeness for a tool with moderate complexity.

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

Parameters2/5

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

Schema description coverage is 0%, and the description only explains the 'gene_id' parameter with examples. Other parameters ('email', 'fields', 'species') are not mentioned, leaving gaps.

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?

The description clearly states it fetches a specific gene by Entrez or Ensembl ID. It uses a specific verb and resource, and distinguishes from sibling tool 'query_genes' by highlighting it is preferred when you already know the ID.

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

Usage Guidelines5/5

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

Explicitly states when to use: when you have a known standard ID and don't need complex search filters. Also mentions it's preferred over 'query_genes', providing clear usage guidance.

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