Get Rain Delay

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

With no annotations provided, the description carries the burden of behavioral disclosure. It does communicate the return content and temporal scope, but it does not explicitly state that the operation is side-effect-free or describe behavior when no rain delay is active. 'Get' implies a read, but the description 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?

The description is a single sentence that front-loads the action and resource, then adds the two key output fields. There is no filler or redundancy; every word contributes useful information.

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 zero-parameter read tool with an output schema, this description provides enough context for an agent to select and invoke it correctly. It names the resource, the temporal scope, and the key returned values, and no additional setup or prerequisite information is needed.

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 tool has zero parameters, so there is nothing for the schema to document. The description therefore does not need to add parameter meaning. A baseline of 4 is appropriate because the no-parameter situation is fully clear from the input 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 uses a specific verb and resource: 'get the current rain delay status.' It further specifies what is included ('remaining hours and end date'), which clearly distinguishes it from sibling tools like set_rain_delay. An agent can tell this is a read operation for current delay state.

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 word 'current' indicates this tool is for reading the active rain delay state, and the sibling set_rain_delay implies the complementary write operation. However, the description does not explicitly spell out when not to use it or name alternative tools, so it falls just short of a 5.

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