open_safari_window

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

No annotations are provided, and the description only states it opens a window with an optional URL. It does not disclose important behaviors like whether the window becomes focused, what happens if Safari is not running, or if it reuses existing windows. The description carries the full burden but is minimal.

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 extremely concise, using just two sentences. It front-loads the main action and parameter, with no redundant words. Every sentence earns its place.

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 has low complexity (one optional parameter) and an output schema exists (though not shown). The description covers the basic action and return type but lacks details on prerequisites (e.g., Safari must be running) or behavioral effects (e.g., window focus). It is adequate but not fully complete.

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?

With schema description coverage at 0%, the description adds value by explaining the 'url' parameter as 'Optional URL to open in the new window'. This clarifies its optional nature and purpose, compensating 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 states the specific action 'Open a new Safari window' with an optional URL, clearly distinguishing it from sibling tools like 'open_safari_tab' (opens a tab) and 'close_safari_window'.

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 alternatives such as 'open_safari_tab' or 'navigate_safari'. Usage context is implied but lacks explicit when-to-use or when-not-to-use instructions.

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