set_render

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

With no annotations, the description carries the full burden, and it does add real behavioral context: samples higher is 'cleaner and slower,' motion_blur blurs fast objects for a cinematic feel, and transparent_background removes the background. It does not disclose persistence or side effects, but for a settings setter the effect explanations are useful.

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 in English, but the Korean section partially repeats the same intent and the overall structure is more of a bulleted note than a clear specification. It is efficient, though not polished, and mixes languages without adding structural clarity.

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?

Given 10 parameters, 0% schema coverage, and no annotations, the description should be much more complete. It omits fps and shutter entirely, does not explicitly state that this tool only changes render settings without rendering, and does not clarify how it relates to sibling render tools. The output schema exists but does not compensate for these gaps.

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 samples, motion_blur, view_transform/look, transparent_background, and resolution/exposure, and gives concrete examples like 'AgX' and 'High Contrast'. However, it completely omits fps and shutter, and width/height are only implied by 'resolution,' leaving some parameters without meaningful guidance.

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 says 'Render quality: samples, motion blur, resolution, exposure and film look,' which identifies the tool's purpose as configuring render settings. It is not a tautology and broadly distinguishes this configuration tool from sibling renderers like render_video and render_preview, but it lacks an explicit verb like 'set' or 'configure' and reads more like a topic summary than an action statement.

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 no guidance on when to call set_render versus render_video, render_preview, set_look, or set_timing. It implies that this tool configures render quality rather than producing output, but it never states that distinction or provides any exclusion criteria.

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