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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, which fully cover behavioral expectations. The description's 'Show' aligns with these annotations and adds no further side-effect details. Since the annotation bar is high and the description is consistent, it is transparent, though it does not add extra context beyond the annotations.

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, clear sentence with no unnecessary words. It is front-loaded with the main action and object, adhering to concise and structured communication.

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 tool is simple with no output schema or complex behaviors. The description sufficiently conveys the purpose and result without needing to explain return values or edge cases. Given the low complexity, the description is complete.

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 tool has zero parameters, so the input schema is trivially 100% covered. There is no parameter semantics to describe, and the description correctly omits any parameter details. This is an ideal scenario for this dimension.

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 explicitly states the tool shows the current MCP platform and adapter versions. This is a specific verb ('show') and resource ('versions'), clearly distinguishing it from sibling tools like authenticate, connect, or marketplace, which serve different purposes.

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 does not explicitly state when to use this tool or provide alternatives. However, given that no sibling tool serves a version-query purpose, the intended usage is implied. Still, the lack of explicit guidance (e.g., 'Use to check compatibility or debug version issues') keeps it at an adequate but not excellent level.

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