Swipe

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

Annotations provide 'destructiveHint: true' but the description adds no further behavioral context, such as the effect of the swipe, duration, or coordinate system. Without annotations, this would be critical, but here it adds minimal value.

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 very short (5 words) but fails to convey essential information, making it under-specific rather than concise. It wastes the opportunity to add value.

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 4 required parameters, no output schema, and a destructive hint, the description is severely incomplete. It does not explain coordinate system, units, gesture behavior, or expected outcomes, leaving the agent with insufficient context.

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 has 0% description coverage for its 4 parameters (x1, y1, x2, y2), and the description does not explain what these parameters represent (e.g., start and end points). The agent cannot infer parameter meaning from the description alone.

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 'Swipe on a specific cordinate' which indicates the action but is vague and misspelled. It does not clarify that the swipe is between two coordinates or distinguish it from the sibling 'Drag' tool. The purpose is only partially clear.

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 on when to use this tool versus alternatives like 'Drag' or 'Click'. The description lacks any context about appropriate scenarios or prerequisites.

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