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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds no behavioral context beyond the fact that it shows current versions. It does not describe return format, whether it performs any network calls, or what 'current' implies. With the annotated safety profile, a neutral score is appropriate.

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, front-loaded sentence with no wasted words. It communicates the essential purpose efficiently. Perfectly concise for a zero-parameter utility.

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 simple read-only version-check tool, the description provides enough to understand its function. It lacks explicit output formatting details (e.g., whether it returns JSON, a string, or a structured object), but given no output schema, this is a minor gap. The tool is not complex enough to require more.

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 0 parameters and the input schema is empty (100% coverage vacuously). The description identifies the subject (MCP platform and adapter versions) but there are no parameters to explain, so the baseline 4 for zero-parameter tools applies.

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 uses a specific verb 'Show' and a clear resource 'current MCP platform and adapter versions.' It directly states the tool's function and distinguishes it from all listed siblings (authenticate, connect, marketplace, report_bug, tcu_inidoneo_consultar, toolkit_info), none of which are about showing versions.

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 when to use (when version information is needed) but does not explicitly discuss conditions, exclusions, or alternatives. While no sibling overlaps, there is no stated 'use this for...' or 'instead of...' guidance. The utility is straightforward, but the tool description remains silent on context.

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