type

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

With no annotations provided, the description carries the full burden, but it only states the basic action. It does not disclose whether typed text replaces or appends content, whether accessibility permissions are required, what 'app-scoped target' means behaviorally, or how the 'strategy' modes affect execution.

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, front-loaded sentence with no filler. It earns its place by stating the action and target scope, though it is too terse to carry all necessary context.

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?

The tool has a nested target object, an enum-based 'strategy' parameter, no output schema, and no annotations. The description does not explain how to construct a target, when 'strategy' matters, or what side effects typing may have, leaving an agent under-equipped for anything beyond the simplest call.

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 0%, so the description must compensate. It adds minimal meaning by identifying 'text' as the content to type and 'target' as an element or app-scoped target, but it leaves the nested target fields and 'strategy' enum entirely unexplained.

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 clear verb and resource: 'Type text into an element or app-scoped target.' This makes the core purpose understandable. However, it does not differentiate from sibling tools like 'key' or 'set_value', which could also be relevant for text-like input.

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 is given about when to use this tool versus alternatives such as 'key', 'set_value', or 'write_clipboard'. The description also does not explain when to choose among the 'strategy' values or when a target should be provided.

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