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

The description adds no behavioral traits beyond what annotations already provide (readOnlyHint=true, idempotentHint=true, destructiveHint=false). It doesn't mention output format, potential side effects, or any additional context. Given annotations already cover safety, the bar is lower, but the description could still note what versions are returned or any caveats.

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 that is front-loaded with the verb and subject. It contains no redundant words or unnecessary details, achieving maximum efficiency.

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 tool with no parameters, no output schema, and clear annotations, the description is mostly complete. However, it does not indicate what the output consists of (e.g., platform version and adapter version strings) or if any format is expected. This minor gap prevents a perfect score.

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 zero parameters, so the baseline is 4. The description does not (and need not) elaborate on parameter semantics since none exist. No information is missing.

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 the specific subject ('current MCP platform and adapter versions'), which uniquely identifies the tool. It deeply distinguishes from sibling tools like authenticate, pncp_* data queries, and report_bug, leaving no ambiguity about its function.

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 explicit guidance is given for when to use this tool or against using alternatives. While the purpose implies usage for version checking or troubleshooting, there is no mention of when not to use it or any alternative version-checking tool. For a simple utility tool, this is acceptable but not thorough.

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