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

With no annotations provided, the description carries full burden. It discloses the key behavior (opens and keeps page open), but lacks details about side effects (e.g., navigation, loading state, error handling). Transparency is adequate but not deep.

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?

Description is a single concise sentence, front-loaded with the action. Every word earns its place; there is no wasted text. Excellent structure for quick agent comprehension.

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?

The tool is simple (no parameters, straightforward action). An output schema exists but is not mentioned; however, the rule says description needn't explain return values if output schema is present. The description could hint at what the tool returns (e.g., page handle), but it is complete enough for its role as an opener.

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 zero parameters and schema coverage is 100%. Description adds no parameter info, but none is needed. For a parameterless tool, baseline is 4; the description simply confirms the tool's action, which is sufficient.

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?

Description states a specific verb ('Open') and resource ('forecast site for Israel'), clearly distinguishing it from sibling tools like enter_weather_search_israel or extract_weather_data_israel. The additional detail 'keep the browser/page open for subsequent tools' further clarifies its role as an initial setup action.

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 'for subsequent tools' implies a sequencing hint, but the description does not explicitly state when to use this tool versus alternatives (e.g., 'Use first, before other weather tools'). There is no guidance on prerequisites 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.
