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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states what the tool does (geocoding) without describing how it behaves: no information about accuracy, rate limits, authentication requirements, error handling, or what happens with invalid inputs. For a geocoding tool with zero annotation coverage, this is insufficient.

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 extremely concise - a single phrase that efficiently communicates the core functionality. Every word earns its place, and there's no wasted verbiage. The structure is front-loaded with the essential information about what the tool does.

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 complexity of geocoding operations (which typically require specific input formats and produce structured outputs), the description is incomplete. With no annotations, no output schema, and a vague input schema, the description doesn't provide enough context for effective use. It doesn't explain what format addresses or coordinates should be in, what coordinate system is used, or what the return values look like.

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 100% description coverage but only documents a generic 'params' object with free-form properties. The description adds no parameter-specific information beyond the schema. Since schema coverage is high, the baseline is 3, but the description doesn't compensate for the schema's vagueness about what specific parameters are needed for geocoding operations.

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 function as a bidirectional geocoder for Korean addresses and coordinates. It specifies both forward (address→coordinates) and reverse (coordinates→address) operations, which provides good specificity. However, it doesn't differentiate this tool from potential sibling geocoders, though none are listed among the provided sibling tools.

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 any prerequisites, limitations, or context for choosing this geocoder over other tools. While sibling tools exist, none appear to be direct alternatives for geocoding, but the description offers no comparative information.

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