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

The annotations (readOnlyHint: true, idempotentHint: true, destructiveHint: false) already disclose the key behavioral traits. The description adds slightly by specifying the exact scope ('platform and adapter' versions), but beyond that it reveals nothing about error behavior, output format, or network dependencies.

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, short sentence of eight words that is front-loaded with the verb and uses each word meaningfully. The description is as concise as possible—no filler, no redundancy.

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 parameterless, read-only version tool, the description is nearly sufficient. It covers the essential 'what' but stops short of mentioning what versions look like (e.g., format) or whether network calls are involved. Given the simplicity and the strong annotations, the description is mostly adequate.

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 description has no parameter semantics to add. The baseline of 4 for parameterless tools applies here, as the description correctly avoids inventing parameters.

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?

Uses a clear verb ('Show') with a specific resource ('MCP platform and adapter versions'). It partially differentiates this tool from siblings like authenticate, connect, or marketplace, though it doesn't explicitly contrast with them. The intent of retrieving version information is unambiguous.

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 context is provided. The description does not mention when to call this tool versus alternatives such as toolkit_info or report_bug, nor does it provide exclusions. For a tool that returns version info, the description omits any guidance on when an agent should rely on it.

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