chitchats_get_rates

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

Annotations already declare readOnlyHint=true, which is supported by the verb 'Get'. The description adds that the response includes costs, delivery times, and carrier options, providing some output context. However, it omits potential behavioral details such as data freshness, pagination, or performance considerations.

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 one concise sentence that front-loads the verb and resource, listing what the tool returns without any unnecessary verbiage.

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 simple read-only tool with one parameter and no output schema, the description covers the essential output aspects (costs, delivery times, carrier options). It is adequate but could be slightly more complete by noting any prerequisites or links to related tools.

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 already fully describes the single parameter 'id' as 'Shipment ID', achieving 100% schema description coverage. The description's mention of 'for a shipment' aligns with this but adds no additional semantic detail beyond the schema.

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 action 'Get' and the resource 'all available shipping rates for a shipment', including costs, delivery times, and carrier options. It is specific enough to distinguish from general shipment operations, though it does not explicitly differentiate from the similar sibling tool refresh_rates.

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?

No guidance is provided on when to use this tool versus alternatives like refresh_rates or get_shipment. The description does not mention any when-to-use or when-not-to-use scenarios, leaving the agent without context for tool selection.

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