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

No annotations are provided, so the description must carry the burden. It describes an input action but does not disclose potential side effects (e.g., clearing previous text) or whether it triggers a search. A simple action like this may be adequately transparent, but more detail would help.

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 extremely concise, using only two lines plus the parameter documentation. Every sentence is necessary and information-dense, with no wasted words.

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 the simplicity of the tool (one parameter) and the existence of an output schema, the description is nearly complete. It lacks context about how this tool fits into a workflow with siblings (e.g., after opening the website, before fetching content), but this is a minor gap.

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 description adds significant value beyond the schema by specifying that the city can be in Hebrew or English, and provides examples. This compensates for the schema's lack of parameter descriptions (0% coverage).

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: typing a city name into the forecast website's search field. It uses a specific verb and resource, and the tool name adds context. However, it does not explicitly connect this action to a broader goal like retrieving a forecast, which would improve clarity.

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 on when to use this tool versus sibling tools. The description only explains the action itself, without mentioning prerequisites (e.g., the website should be open) or when not to use it.

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