select_weather_forecast_city_israel

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

No annotations are provided, so the description carries full disclosure burden. It usefully reveals that selection is deterministic ('first result'), meaning the agent cannot choose a specific city, but it omits what happens if the list is empty, whether it navigates to a new page, and any auth or error 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?

A single, tight sentence with no padding, and the key constraint ('first result') is placed prominently. Appropriate length for a zero-argument UI step.

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?

An output schema exists so return values need not be explained, and there are no parameters. What remains unstated is the workflow contract (what must precede this call, what state follows it), which matters for a sequential UI-automation tool.

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 takes zero parameters, so there is nothing for the description to disambiguate. The baseline for a parameterless tool is 4, and the description adds no misleading parameter claims.

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 verb (selects) and a specific target (the first result in the city list opened by the search), which distinguishes it from siblings like enter_weather_forecast_city_israel or open_weather_forecast_israel. It stops short of explicitly naming the alternative tools, but the action and target are clear.

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 phrase 'the city list that was opened following the search' implies this step follows a search and a list-opening step, giving sequencing context. However, it never states when to use this versus entering a city directly, nor any preconditions or failure conditions.

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