get_status

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

No annotations are provided, so the description carries the full burden. It adds context by noting the tool is 'free' and lists the returned data, implying a harmless read-only operation. However, it does not explicitly state side effects, auth requirements, or rate limits, which is a minor gap for a zero-parameter status tool.

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: 'Service status, payment mode, and component health (free).' It is front-loaded with key information and contains no filler. Every word earns its place.

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 zero-parameter tool with no output schema, the description covers the main purpose and the fact that it is free. It could mention the response format or more detail about 'component health', but for a status endpoint, the information is adequate. The tool's simplicity lowers the bar.

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 input schema has zero parameters, so the description need not explain parameter semantics. The rule for 0 params is baseline 4. The description does not add anything beyond that, but it is not needed.

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: it provides service status, payment mode, and component health. This distinguishes it from sibling tools focused on fees, forecasts, and network snapshots. The name 'get_status' combined with the description gives a specific verb+resource.

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 usage for checking API status and payment mode, but does not explicitly state when to use it versus alternatives or any exclusions. It indirectly differentiates from siblings by listing unique information, but no direct 'use when' guidance is given.

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