kitty_set_spacing

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

No annotations are provided, so the description must fully disclose behavioral traits. It explains the format of settings but omits details about side effects (e.g., immediate application, repaint), scope of effect (e.g., currently focused window), or any potential limitations. The description is minimal in this regard.

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 comprises two sentences that are direct and to the point. It front-loads the purpose and immediately follows with essential usage details. There is no unnecessary information.

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's simplicity (5 parameters, no output schema), the description covers the key aspects: action, format, and reset behavior. It could mention the default window scope but the schema's 'all' parameter implies it. Overall, it's adequately complete for a setter tool.

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%, so the schema already documents all 5 parameters. The description adds value by explaining the 'key=value' format and the 'default' reset value, but this only marginally augments what is in the 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 tool sets paddings and margins for kitty windows. It specifies the resource (kitty windows) and the action (set spacings). While it doesn't explicitly distinguish from siblings, the name and description are sufficiently unique among the listed sibling tools, which focus on other actions like actions, colors, or text.

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 provides usage examples and mentions using 'default' to reset, which is helpful. However, it does not specify when to use this tool versus alternatives, nor does it offer guidance on prerequisites or conditions for use.

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