open_weather_forecast_israel

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

Without any annotations, the description fully discloses the tool's behavior—opening a browser and navigating to a specific page. It does not hide any side effects, though it could mention potential delays or the need for network access, but that is minor.

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 brief and to the point, consisting of two short sentences with no unnecessary detail. It conveys the core function and recommendation efficiently.

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 that the tool has no parameters and no output schema, the description provides all necessary context: what it does and its role relative to sibling tools. The statement that it is a recommended opener completes the operational picture.

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 no parameters, so the baseline of 4 applies. The description is consistent with this and adds no ambiguity.

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 that the tool opens a browser and navigates to the weather forecast page for Israel, using specific action verbs and a defined target. It also distinguishes itself from sibling tools by positioning itself as a recommended opening step.

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?

Explicitly instructs to use this tool before the others, giving clear guidance on when it should be invoked. The recommendation to open with this tool provides a direct usage context.

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