Close folder window

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

With no annotations, the description carries the behavioral disclosure burden. It does disclose the key behavior—closing any matching open windows—but does not cover edge cases such as no matching window, invalid path, or whether the operation is a no-op. It is clear but incomplete.

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?

One concise sentence that front-loads the action and target. Every word earns its place; there is no redundancy or filler.

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 one-parameter tool with no output schema, the description adequately covers the core action and matching condition. Minor gaps remain around edge-case behavior and explicit comparison with sibling tools, but nothing blocks correct invocation.

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?

Schema description coverage is 100%, and the single 'path' parameter is already well described in the schema as the folder path whose windows should be closed. The description adds no new parameter semantics beyond restating 'given folder path'.

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 uses a specific verb ('Close'), names the resource ('File Explorer window(s)'), and scopes the action to windows 'currently showing the given folder path'. This clearly differentiates it from siblings like close_all_folder_windows.

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 description gives a clear condition for use: close windows for a specific folder path. It does not explicitly mention alternatives such as close_all_folder_windows for closing all windows, but the targeted-scope wording makes the intended use reasonably obvious.

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