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

Since no annotations are provided, the description carries the full burden. It effectively communicates that this is a verification/checking operation (non-destructive) and implies it requires a valid API key. However, it doesn't specify response format, error conditions, or rate limits, leaving some behavioral aspects unclear.

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 perfectly concise with two sentences that each earn their place. The first states the purpose, the second provides usage guidance. No wasted words, and the most important information (what it does) is 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?

For a zero-parameter verification tool with no annotations or output schema, the description is nearly complete. It explains purpose, usage context, and implicit requirements. The only gap is lack of information about what specific status information or errors might be returned.

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?

With 0 parameters and 100% schema description coverage, the baseline would be 4. The description adds value by explaining the implicit context: it verifies 'your Kit API key' and 'connection status', providing semantic meaning beyond the empty parameter schema.

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 tool's purpose with specific verbs ('verify', 'check') and resources ('Kit API key', 'connection status'). It explicitly distinguishes this from sibling tools by positioning it as a setup verification tool, unlike the management-focused siblings.

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 provides explicit usage guidance: 'Use this as the first tool call to confirm setup.' This clearly indicates when to use this tool (initial setup verification) versus when to use sibling tools (ongoing management operations).

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