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

The annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering the safety profile. The description adds no extra behavioral details beyond what the annotations provide (e.g., side effects or rate limits). It does not contradict the annotations, but it doesn't enhance transparency beyond the existing metadata.

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, concise sentence: 'Show the current MCP platform and adapter versions.' It uses a clear verb-object structure with no extraneous words, making it efficient and easy to parse.

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 simple, parameterless tool with no output schema, the description is fully complete. It tells the user exactly what information will be obtained (current MCP platform and adapter versions). No additional context is necessary.

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?

There are no parameters in the input schema, so the coverage is effectively 100%. The description does not need to explain parameters. Per the baseline rule for high coverage, a score of 3 is appropriate; the description adds no parameter-related information since there are none to describe.

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 clearly states the tool's function: 'Show the current MCP platform and adapter versions.' It identifies the specific action (show) and the resource (versions). This distinguishes it from sibling tools like authenticate, connect, or report_bug, 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 mention when to use this tool versus alternatives. However, given the distinct function of displaying version info, usage is implied for obtaining platform/adapter version details. There is no explicit guidance on conditions or contexts, so it falls short of being fully clear.

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