get_freight_transportation_index

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

No annotations provided. Description implies read-only behavior and mentions the index is a leading indicator, but lacks details on update frequency, data freshness, or any limitations. Adequate but could be more transparent.

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?

Description is well-structured and informative, but slightly verbose. The first two sentences are clear, while the third adds context. Could be tightened without losing meaning.

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 no output schema, the description adequately explains the return values by listing the indicators. It provides sufficient context about the tool's relevance and use cases.

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?

No parameters, so baseline is 4. The description adds significant value by enumerating the specific indicators returned (TSI, truck tonnage, etc.), which is not present in the empty 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?

Clearly states the tool gets the US freight transportation health index from a specific source (Bureau of Transportation Statistics). Lists specific components (TSI, truck tonnage, etc.) and distinguishes it from sibling tools by focusing on freight health.

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?

Mentions target users (logistics companies, freight brokers, economic analysts) and context (tracking US freight demand trends), but does not explicitly state when to use this tool over alternatives like get_freight_rate_observations or get_rail_freight_status.

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