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 discloses that the tool returns server version, Nominatim URL, cache stats, and tool count, which adds useful behavioral context beyond basic purpose. However, it lacks details on error handling, performance characteristics, or whether this is a read-only operation (implied but not stated).

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 appropriately sized and front-loaded, with the core purpose stated first. Additional details are organized in clear sections (Args, Returns), and every sentence adds value without redundancy. It efficiently conveys necessary information in a structured format.

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?

Given the tool's low complexity (one optional parameter) and lack of annotations/output schema, the description is reasonably complete. It covers the purpose, parameter semantics, and return content. However, it could improve by mentioning that this is a read-only status check and providing brief usage context relative to siblings.

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 description adds significant meaning beyond the input schema, which has 0% coverage. It explains the 'output_mode' parameter with its options ('json' or 'text') and default value, effectively documenting the single parameter. Since there's only one parameter and the schema provides no descriptions, this compensates well, though it could note that 'text' might be human-readable output.

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: 'Get geocoder server status.' This specifies the verb ('Get') and resource ('geocoder server status'), making it easy to understand what the tool does. However, it doesn't explicitly differentiate from sibling tools like 'geocoder_capabilities', which might provide overlapping information about server capabilities.

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 no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'geocoder_capabilities' or explain scenarios where checking server status is necessary (e.g., before batch operations or troubleshooting). Without this context, users might struggle to choose between similar tools.

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