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

Annotations already declare readOnlyHint and idempotentHint; the description adds 'platform and adapter versions' as the concrete return scoping, which is helpful but minimal. It does not specify output structure, potential network behavior, or error states, though these are less critical for a low-risk version tool.

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?

A single, tightly scoped sentence with no filler or duplication of structured metadata. Every word adds semantic value.

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 informational tool with strong annotations, the description covers what versions are returned (platform + adapter), though it could mention whether this validates a server connection or just reads local metadata. Sibling tools like connect suggest a possible prerequisite, but this is a minor gap for a tool of this simplicity.

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?

With zero parameters, the schema is trivially complete at 100% coverage. Per the baseline for no-parameter tools, a 4 is appropriate since there is no parameter ambiguity to resolve.

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') tied to a clear resource ('the current MCP platform and adapter versions'). It distinguishes itself from siblings like connect and toolkit_info by naming the exact output scope.

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?

No usage guidance is provided. The description does not clarify when an agent should use this instead of sibling tools like toolkit_info, nor does it mention preconditions (e.g., requires active connection).

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