vmix_inspect

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds useful context by saying 'real' state is read, implying live system data, but it does not disclose additional behavior such as failure modes, connection requirements, or output shape.

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?

One compact sentence that leads with the action verb and then lists the concrete items read. There is no filler, repetition, or unnecessary 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?

For a zero-parameter, read-only inspection tool, the description reasonably captures what data will be returned by enumerating vMix state categories. Minor gaps remain around error/connection behavior, but the low complexity and annotation coverage make the description sufficiently complete.

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?

The input schema has zero parameters, so parameter-level documentation is unnecessary. Per rubric guidance, 0 params receives a baseline of 4; no additional parameter semantics are needed.

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 specific verb ('Read') and names concrete resources: vMix inputs, GUIDs, title fields, layers, program, preview, and overlays. It clearly communicates a read-only inspection tool, though it does not explicitly differentiate itself from similar sibling tools like vmix_operation_get.

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 wording 'Read real vMix inputs' implies the tool is for inspecting live vMix state rather than modifying or configuring it. However, it provides no explicit when-to-use guidance, exclusions, or mention of alternative tools.

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