traffic_511_query

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

The readOnlyHint annotation already signals a safe read operation, and the description adds useful behavioral context by explaining what each action returns (e.g., camera image URLs, RWIS weather fields, sign content). It does not cover rate limits, pagination, or response format, but the added action semantics go beyond the annotations.

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 compact and front-loaded, with a clear first sentence and a well-organized action list. Every line conveys necessary information without filler.

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 two-parameter query tool with readOnlyHint and action descriptions, the context is largely sufficient. The absence of an output schema is compensated by the action descriptions, though the response shape is not detailed and the '15 states' claim is not fully matched by the schema's listed state codes.

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 coverage is 100%, with both parameters described in the schema. The description adds meaningful semantics by elaborating the five action enum values, turning terse labels into understandable data types, though the state parameter is not further enriched.

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 tool 'Query real-time traffic data for a state' and lists five concrete action types, making the purpose specific and actionable. It distinguishes itself from state-specific siblings like md_traffic_incidents and the more general traffic_511_list.

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 usage by specifying 'for a state' and enumerating supported actions, but it does not explicitly contrast with alternative tools such as traffic_511_list or the Maryland-specific traffic tools. It lacks explicit when-to-use versus alternatives guidance.

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