get_element_value

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

Annotations already indicate readOnlyHint=true, so agents know it's a safe read operation. The description adds context about the UIA Value pattern, which hints at platform-specific behavior but does not disclose what happens if the element lacks the pattern or other behavioral traits.

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?

Single sentence, front-loaded with action and method, no wasted words. Efficient and direct.

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 simple tool with one parameter and read-only annotations, the description is mostly adequate. However, it does not explain what 'value' means in the UIA context (e.g., text, numeric), nor does it describe the return format or error behavior, leaving some ambiguity given no output schema.

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% (elementId description 'Element ID returned by find_element'). The tool description adds no further meaning beyond the schema, meeting the baseline for parameter semantics.

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 verb 'Get' and resource 'value of an element via the UIA Value pattern', indicating a specific UI automation mechanism. It differentiates from siblings like get_text or get_attribute by referencing the UIA Value pattern, but does not explicitly contrast with alternatives.

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 siblings such as get_text or get_element_info. The description lacks any when-to-use, when-not-to-use, or prerequisite information, leaving the agent to infer context.

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