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

No annotations are provided, so the description carries the full burden. It mentions 'paste text directly (without typing),' which implies a UI automation action, but lacks details on permissions, side effects, or error handling. The description adds some behavioral context (speed, character support) but is incomplete for a tool that likely interacts with system UI.

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 two concise sentences with zero waste: the first states the core action, and the second provides key comparative advantages. It is front-loaded with essential information and efficiently conveys usage guidance.

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 no annotations and no output schema, the description is moderately complete: it covers purpose and guidelines well but lacks details on behavioral aspects like error conditions or system dependencies. For a UI automation tool with one parameter, it's adequate but could benefit from more context on limitations or prerequisites.

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%, with the single parameter 'text' documented as 'Text to paste.' The description adds no additional parameter semantics beyond what the schema provides, such as format constraints or examples. Baseline 3 is appropriate since the schema fully covers the parameter.

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 specific action ('paste text directly') and distinguishes it from the sibling tool 'bytebot_type_text' by noting it's faster and handles special characters/emojis. It explicitly contrasts with an alternative, making the purpose distinct and well-defined.

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 explicit guidance on when to use this tool versus alternatives: it states 'Faster than type_text' and 'works with special characters/emojis,' indicating this is preferred over type_text in those scenarios. This directly addresses sibling differentiation and usage context.

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