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

The annotations already establish readOnlyHint, idempotentHint, and destructiveHint false. The description adds no deeper behavioral detail beyond saying 'current' versions, and it does not contradict the annotations. Given the strong annotation coverage, the simple description suffices but adds little extra context.

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?

The description is a single, front-loaded sentence with no surplus words: 'Show the current MCP platform and adapter versions.' Every word contributes to the meaning.

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 zero-parameter, no-output-schema, read-only version display tool, the description is complete. There is no workflow context, destination, or pagination to specify, and the existing annotations cover side effects well enough.

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?

The input schema has zero parameters, so there is also no parameter-specific meaning to explain. According to the established baseline for zero-parameter tools, a 4 is appropriate since there is nothing for the description to add beyond the schema.

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 uses the specific verb 'Show' and identifies an exact resource: 'the current MCP platform and adapter versions.' This distinguishes it from sibling tools like authenticate, marketplace, or report_bug, none of which are about version inspection.

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 description implies a self-evident use case, but it does not explicitly state when to choose this tool over alternatives such as toolkit_info. There is no clear exclusions or alternative guidance, but for a version lookup the intended usage is fairly obvious.

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