status

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

With no annotations, the description carries the burden of disclosing behavioral traits. It states what the tool checks (auth status and API connectivity), but does not describe side effects, return format, or whether it is read-only. This is adequate but lacks depth for a tool with no structured 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, tightly worded sentence that gets straight to the point. Every word adds meaning, no fluff or redundancy, and it is front-loaded with the verb 'Check'.

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 and no output schema, the description provides the essential purpose and services checked. It does not detail return values, but for such a simple diagnostic tool, the agent can invoke it without ambiguity. A minor gap is the lack of information about the response structure, but overall it is complete enough for selection and invocation.

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 schema coverage is trivially 100%. With no parameters to explain, the description does not need to add parameter-level semantics. The baseline of 4 applies, and the description correctly focuses on the tool's behavior rather than nonexistent parameters.

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 ('Check') and clearly identifies the resource: authentication status and API connectivity for the renamed.to service. This unambiguously distinguishes it from sibling tools like pdf_split, rename, and watch, which are action-oriented.

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 the tool—when you need to verify service status or connectivity—but it does not explicitly state when to use it versus alternatives. There are no exclusions or alternative mentions, so usage guidance is only implied rather than explicit.

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