geocode

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

No annotations are provided, so the description carries the full behavioral disclosure burden. It says the tool returns latitude, longitude, and DigiPin, but does not mention rate limits, error behavior, address ambiguity handling, or whether it is read-only. For a geocoding API, several behavioral assumptions remain undisclosed.

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 two short, front-loaded sentences with no filler. The first sentence names the verb, input, and primary outputs; the second expands on the return values. There is slight redundancy between 'get DigiPin code and coordinates' and 'including latitude, longitude, and DigiPin', but the text is still efficient.

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 5-parameter tool with no output schema and no annotations, the description gives the core mapping from address to coordinates/DigiPin but omits return format details and guidance on when to use related geocoding/lookup tools. The schema covers parameters, so the main completeness gap is behavioral and alternative-selection context.

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?

Schema description coverage is 100%, so baseline 3 applies. The description's mention of address and outputs is consistent with the schema but adds no parameter information beyond what the schema already states, such as the optional fields or the India country default.

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 ('Geocode') and resource ('an address') and clearly states the expected outputs ('DigiPin code and coordinates', 'latitude, longitude, and DigiPin'). It is not a tautology and is semantically distinct from reverse_geocode or lookup_location_from_digipin. However, it does not explicitly name or differentiate from any sibling, which keeps it just short of 5.

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 an address-to-coordinates use case, but it never states when to choose this tool over alternatives such as reverse_geocode, batch_geocode, or autocomplete. No exclusions or alternative conditions are provided, leaving tool selection to inference.

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