Get Server Capabilities

get_server_capabilities
Read-onlyIdempotent

Retrieve GenCC-Link's available tools, classification vocabularies, response modes, workflows, and data freshness. Use capabilities_version to avoid refetching unchanged data.

Instructions

Return the GenCC-Link tool inventory, classification vocabulary and ranks, response modes, recommended workflows, error codes, resources, and live data freshness. Compare capabilities_version to skip re-fetching when unchanged.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnly and idempotent behavior. The description adds value by disclosing the version comparison strategy and the response content (freshness, error codes, workflows). No contradictions.

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-loaded with the main action and content list, followed by a practical usage tip. Every word earns its place.

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?

With no output schema, the description compensates by listing all major return categories and the version-check workflow. This is a complete and self-contained description for an agent to select and invoke the tool.

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?

No parameters exist, so description holds no param burden. It references `capabilities_version` as a return field concept, not a parameter, which is helpful context.

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?

Description uses a specific verb ('Return') and clearly identifies the resource: GenCC-Link server capabilities. It lists the contents (tool inventory, vocabulary, response modes, etc.), distinguishing it from sibling tools that query genes, diseases, and curations.

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

Usage Guidelines4/5

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

The description provides clear usage context: fetch capabilities and compare `capabilities_version` to avoid re-fetching when unchanged. It does not explicitly name alternatives, but the unique purpose among siblings is self-evident.

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