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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is fully covered structurally. The description adds nothing beyond that — no mention of pagination, filtering, or what a versions listing contains.

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

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

Short, but only because it is under-specified; the text repeats 'GET /api/versions' verbatim twice, which is pure waste, and nothing is front-loaded beyond the endpoint path.

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

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

For a tool with a free-form 'query' object, 0% parameter documentation, and no output schema, the description provides no usable context. An agent cannot know what this endpoint returns or how to shape the query object from this definition.

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

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

Two parameters (query, params) with 0% schema description coverage and no information in the description. The agent has no idea what the open-ended 'query' object accepts, and the description does nothing to compensate.

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

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

The description is essentially the tool name echoed back: 'GET /api/versions' twice, plus the operation ID. It restates the HTTP path without stating what the tool actually returns or how it differs from siblings such as get_versions_by_id or get_versions_compare.

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

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

The only actionable line points the agent to describe_operation for native request schemas, which is a schema hint rather than when-to-use guidance. There is no distinction from get_versions_by_id or get_versions_compare_by_id1_by_id2, which are the obvious alternatives.

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