kitty_set_tab_title

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

The description discloses the reset behavior but omits important details like prerequisites (e.g., whether the tab must be in focus), error handling for invalid match expressions, or side effects. With no annotations, more behavioral disclosure is expected.

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 a single, clear sentence with no extraneous information, making it highly concise and well-structured.

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 simplicity of the tool (2 params, no output schema), the description provides essential information including the reset feature. However, additional details about the match expression and return behavior would enhance completeness.

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 coverage is 100%, but the description adds value by explaining that omitting the title resets to the active-window-controlled title, providing context beyond the schema's basic type/description.

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 the title for specified kitty tabs and specifies a reset behavior when no title is provided, which distinguishes it from sibling tools like kitty_set_window_title.

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 implies usage for setting or resetting tab titles but lacks explicit guidance on when to use this tool versus alternatives such as kitty_set_window_title or other tab-related tools.

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