Tuanjie Screenshot Capture

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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the safety profile is covered. The description adds that the tool can both capture views and control Game View recording, and that action-specific parameters are passed through unchanged, but it does not detail side effects, output artifacts, or recording lifecycle behavior.

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 compact: two sentences, front-loaded purpose, and a necessary enumeration of supported actions. There is no filler or repetition of schema data.

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?

There is no output schema, yet the description does not explain return values, output files, or effects of starting/finishing recording. With ten actions and open passthrough of extra parameters, plus a destructive annotation, the description leaves key invocation-relevant details unstated.

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 schema has one required enum parameter with 0% description coverage, so the description must compensate. It enumerates all ten actions and groups them conceptually as captures versus recording controls, adding meaning beyond the raw enum. However, it does not describe what the action-specific parameters are or how they affect each action, only noting that they are passed through unchanged.

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 opens with an active verb ('Captures') and names the concrete resources: editor, scene, camera, asset, and UI views, plus Game View recording control. This clearly distinguishes it from sibling tools like unity_gameview or unity_ui_toolkit, which have different scopes.

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, and no exclusions or selection conditions are stated. The supported-actions list implies usage, but an agent is left to infer when this screenshot tool should be preferred over the many related sibling tools.

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