open_weather_forecast_israel

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

Discloses that it opens a Chromium browser and navigates to a website, indicating it is a browser automation step. Returns success/failure message. Lacks details on side effects (e.g., new window, blocking behavior) or what happens on failure. Minimal but adequate.

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?

Extremely concise: two sentences covering action and return value. No extraneous information, front-loaded with the key action.

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 simple tool with no parameters, the description is complete enough for its role. It explains what it does and what it returns. However, it could specify the exact URL or that the output is a simple status message, not page content.

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?

No parameters exist (0 params), so baseline score is 4. Description does not need to add parameter meaning beyond 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 clearly states the action (opens a Chromium browser) and the target (Israeli weather forecast website). It distinguishes from sibling tools which handle city-specific actions and content retrieval. However, it could be more specific about exact URL or website name.

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 alternatives. Does not mention prerequisites, context, or when to use sibling tools like 'enter_weather_forecast_city_israel' or 'get_weather_page_content'.

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