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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safe-read nature is covered. The description confirms a read operation but adds no behavioral detail beyond what annotations convey (e.g., no performance, output format, or edge-case info). Does not contradict annotations.

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 covers the essential purpose. It could be slightly more specific about output format, but for a simple getter, this is appropriately brief and front-loaded.

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 tool is trivial: no parameters, no output schema, and annotations cover safety. The description fully covers what an agent needs to use this tool correctly. The task is simple enough that no additional detail is 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?

There are 0 parameters, so the description's only job is to state what the tool returns, which it does. The description clearly indicates the output will be version information for MCP platform and adapters, which is sufficient for a no-parameter tool.

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 'Show the current MCP platform and adapter versions' uses a specific verb ('Show') and identifies the exact resource ('MCP platform and adapter versions'). It's clear and distinct from siblings like authenticate or connect, though it doesn't name a specific sibling as an alternative.

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 its use as a simple status/version query, but provides no explicit when-to-use guidance or mention of alternatives; however, given its generic nature, minimal guidance is needed. It doesn't mislead but offers no explicit context.

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