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

Annotations clearly indicate readOnlyHint: true, idempotentHint: true, and destructiveHint: false, which align with the non-mutating nature of showing versions. The description uses 'Show' which consistently implies a read-only operation with no side effects.

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 concise and to the point, using a single clear sentence. The schema is minimal and properly structured with an empty properties object, which is appropriate for a parameterless tool.

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?

The description covers the main purpose, and annotations provide behavior context)Skip_significant gaps. However, there is no output schema, so the exact structure of the version information is not specified, which is a minor omission for such a straightforward tool.

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 and the property list is empty, which matches the tool's purpose. Since there are no parameters, there is no ambiguity about what inputs are expected.

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 'Show the current MCP platform and adapter versions' unambiguously states what the tool does. It clearly indicates that it retrieves version information for both the MCP platform and adapters.

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 tool is self-explanatory and requires no parameters or prerequisites. However, there is no explicit guidance on when to invoke it relative to other sibling tools like 'authenticate' or 'connect', though its simplicity makes it obvious for version queries.

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