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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is covered. Description adds no extra behavioral context (e.g., output format, network access), but given the trivial nature, this is acceptable. No contradiction.

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?

One single sentence, front-loaded, no fluff. Perfectly concise.

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 zero params, good annotations (readOnly, idempotent, non-destructive), and clear purpose, the description is complete. It might benefit from noting the output is version strings but the output schema is absent, so the agent can infer from 'show versions'. Still 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 and the schema has full coverage (100%), so the description doesn't need to explain parameters. The baseline is 4 for no params, and the description adds no extra param info, but that's fine.

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?

Clearly states the tool's function: show current MCP platform and adapter versions. Specific verb 'show' with explicit resource (versions). Differentiates from siblings like connect, authenticate, etc.

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 when-to-use or exclusions, but the purpose is self-evident for a simple version query. With no parameters, usage guidance is minimal; it's implied that it's used when you need version info.

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