validate_and_geocode_address

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

There are no annotations, so the description must carry the full behavioral burden. It does disclose the external Google Maps Platform dependency and the expected outputs, but it does not state whether the operation is read-only, whether it makes a network call with associated cost, or what happens on validation/geocoding failure.

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?

A single sentence packs in the tool's purpose, geographic scope, external API, and main outputs without excess. Key information is front-loaded.

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?

The description mentions the important output concepts (sublocality, coordinates, confidence score), which is useful given there is no output schema. However, it does not explain the meaning of the confidence score, how optional thana/district parameters affect results, or failure/edge-case behavior, leaving some ambiguity for a tool with no annotations.

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 the schema already documents all three parameters. The description adds no parameter-specific detail beyond what is in the schema, so the baseline score of 3 is appropriate.

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 names a specific verb-resource pair ('Validate and geocode a Bangladesh delivery address') and states the key outputs: administrative sublocality, lat/lng coordinates, and delivery confidence score. This clearly distinguishes it from siblings like list_couriers, track_parcel, and check_fraud_risk.

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 the tool is used when address validation or geocoding is needed, but it gives no explicit guidance on when to choose this tool over alternatives such as calculate_delivery_zone_and_fee or check_fraud_risk. No exclusions, preconditions, or alternative conditions are mentioned.

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