geocode

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

With no annotations, the description explains output units and provides an example. It could mention rate limits or authorization, but the transparency is sufficient for a simple read-only geocoding 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?

Two clear sentences plus an example, front-loaded with the purpose. No unnecessary words or redundancy.

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 a simple input schema with one parameter and an output schema (though not detailed), the description covers input, output format, units, and an example, making it complete enough for correct 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 'query' parameter has 0% schema description coverage, but the description clarifies it is a 'place name' and gives an example, adding necessary meaning beyond the schema structure.

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 verb ('geocode') and resource ('place name to WGS84 coordinate'), and the sibling 'reverse_geocode' implies the opposite direction, distinguishing this tool.

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 indicates forward geocoding usage but does not explicitly state when not to use it or provide alternatives beyond the implied reverse geocode.

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