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

With no annotations, the description must disclose behavioral traits, such as side effects or state changes. It only describes input format (Hebrew/English) but does not explain what happens after entering the city name (e.g., whether it triggers a search, modifies state, or returns data).

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 concise, with two sentences and a clear args list. It avoids unnecessary detail, though the first sentence could be merged with the args explanation. Overall, it is well-structured and efficient.

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 tool has one parameter and an output schema (not described), the description omits what the tool returns or how it fits with siblings. It lacks context about the tool's role in the weather forecast workflow (e.g., input step before opening or selecting).

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 schema has no description for 'city_name' (0% coverage). The description adds useful semantics: 'City name to search for (Hebrew or English), e.g. ירושלים or Jerusalem.' This clarifies supported languages and provides concrete examples, compensating well for the lack of schema documentation.

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 says 'Type a city name into the weather2day search box,' which implies the tool inputs a city name for weather forecast, but it does not explicitly state the tool's function. The purpose is inferred from the name and action, but lacking direct 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 is provided on when to use this tool versus its siblings (e.g., select_weather_forecast_city_israel, open_weather_forecast_israel). The description does not mention alternatives or context for use.

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