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

The annotations already declare the tool as readOnly, non-destructive, and idempotent. The description adds specificity about what versions are shown (MCP platform and adapter), which is useful but minimal. No contradictions or additional behavioral details 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 redundancy. It front-loads the action and is perfectly concise 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?

With no parameters and no output schema, the description sufficiently explains what the tool returns (platform and adapter versions). It is complete for the simplicity of the tool, though it doesn't elaborate on potential output formats or errors, but that's not critical here.

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 IAW the input schema (empty properties). Per rubric, a 0-parameter tool gets baseline 4, and the description doesn't need to explain parameters. It correctly focuses on the output.

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 a specific verb ('Show') and a clear resource ('current MCP platform and adapter versions'). It is unambiguous and distinct from sibling tools like authenticate, connect, or detran_consultar, which clearly have 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 implies usage (when you need to check current versions), but there is no explicit guidance about when to prefer this tool over alternatives or any exclusion scenarios. It is not misleading, but it lacks explicit direction.

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