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

The annotations already state read-only, non-destructive, and idempotent behavior, and the description is consistent with them. It adds useful context by specifying that both the MCP platform and adapter versions are included, though it does not describe output shape or edge cases.

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, well-structured sentence with no waste. Every word adds meaning.

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?

Given the tool's simplicity, zero parameters, and read-only annotations, the description is largely sufficient for an agent to select and invoke it. It briefly explains what output to expect, though a sentence naming toolkit_info as the alternative for broader environment details would improve completeness.

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?

This tool has zero parameters and 100% schema coverage, so there is no parameter ambiguity for the agent to resolve. A no-parameter tool baseline of 4 is appropriate.

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 names the action ('Show') and the resource ('current MCP platform and adapter versions'), so an agent can tell what the tool returns. It is specific, but it does not explicitly differentiate itself from sibling tools like toolkit_info.

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 this tool should be used when an agent needs version information, but it gives no explicit guidance about when to choose it over toolkit_info or other sibling tools. For a zero-parameter informational tool, this implied usage is enough.

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