wpf_set_text

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

With no annotations provided, the description carries full burden and details behavioral traits: default uses IValueProvider.SetValue (clean, no focus, raises events), fallback to direct property setting, and physical mode's focus, clear, and type behavior. It also declares 'STATE-CHANGING.' Missing details on potential side effects or error conditions, but sufficiently transparent.

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 information-dense and front-loaded with the primary purpose. It efficiently covers default behavior, fallbacks, and the physical mode in a readable structure. Some minor redundancy could be trimmed, but overall concise.

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?

For a text-setting tool with no output schema, the description covers the main behaviors, fallback mechanism, and physical typing mode. It does not explain return values or error handling, but given the tool's expected behavior, it provides enough context for an agent to use it correctly.

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 explains the 'text' parameter as the value to set, 'physical' as a boolean for OS keyboard input, and 'element_handle' by context as the target element. While element_handle is not explicitly defined, the purpose is clear. The description adds meaning beyond the bare 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 text/value of UI elements like TextBox and ComboBox, naming the primary method (IValueProvider.SetValue) and fallbacks. It distinguishes itself from sibling tools focusing on clicking, selecting, or sending keys.

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 explains when to use the default mode vs physical=true (focused typing), providing clear context for choosing between them. However, it does not explicitly contrast with sibling tools like wpf_send_keys or wpf_set_property, leaving some ambiguity about when to prefer this tool over alternatives.

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