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

The annotation already marks it as readOnly, idempotent, and not destructive, so the safety profile is clear. The description adds that it retrieves both platform and adapter versions, which is useful but not extensive. No conflicting behaviors mentioned.

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 without any unnecessary words. It is well-structured and easily parsed.

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 description provides sufficient context for a no-parameter version tool. It specifies the exact information returned (platform and adapter versions) and the annotations cover operational safety. No further details seem 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?

The tool has no parameters, and the schema is fully covered (empty object). There is no possibility of misuse, so the agent can safely invoke it without any parameter concerns.

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 action ('Show') and specific resources ('current MCP platform and adapter versions'). It is distinct from sibling tools like 'authenticate' or 'toolkit_info' by focusing solely on version information.

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 the tool is used to retrieve version information, but does not explicitly state when it should be used over alternatives (e.g., toolkit_info). Given its simplicityhols, this is adequate, though a more explicit note on intended scenarios would improve it.

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