set_render

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

Describes the visual outcome for each flag value, which adds useful behavioral context beyond the annotations. The annotations already cover the mutation and non-destructive nature of the operation, so the description doesn't need to repeat those. The word 'toggle' slightly overstates what is actually a set operation, but the flag explanation resolves the ambiguity.

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 short and front-loaded, with the parameter explanation immediately following the main statement. The bilingual parentheticals repeat the English content without adding new information, but overall it remains efficient and easy to parse.

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 single-boolean tool with no output schema and annotations covering safety traits, this description is complete enough for an agent to invoke it correctly. No additional return-value or side-effect documentation is necessary at this complexity level.

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 provides only a boolean type and a default value, with no parameter description. The description fully compensates by explaining that True means rendered view and False means wireframe, leaving no ambiguity about how to set the flag.

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?

States a specific verb and resource: toggle solid rendering mode, with the flag parameter defining the two states. This distinguishes it from display-related siblings like set_view_angle, reset_display, and switch_display_stage.

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 gives clear context: this tool controls whether the model is shown rendered or as wireframe. It doesn't explicitly name alternative tools or exclusion conditions, but for a one-parameter view-mode switch the usage context is sufficiently clear.

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