Get route stops

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only says 'Get route directions and stops,' which implies a read operation but does not explain output structure, ordering, whether directions and stops are separate, or any route-specific behavior.

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 short sentence with no filler and the action is front-loaded. It is concise, though the phrase 'directions and stops' could be more precise.

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 tool with no output schema and no annotations, the description provides only a minimal hint of what is returned. It does not clarify how directions are represented, how stops are ordered, or how this tool relates to the many sibling route/stop tools, leaving the agent with significant ambiguity.

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 single required parameter routeId is fully described in the schema as 'transport12 route id.' with constraints, so schema coverage is 100%. The description adds no additional meaning beyond the schema, but the schema already handles the parameter semantics adequately.

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 action ('Get') and a clear resource ('route directions and stops'), so the core purpose is understandable. However, it does not differentiate this from sibling tools like get_route or get_stop_routes, and 'directions' is somewhat ambiguous.

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 gives no when-to-use or when-not-to-use guidance. It does not mention alternatives such as search_stops, get_route, or get_stop_routes, and it leaves the choice of this tool over its siblings entirely to inference.

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