setup_render

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

With no annotations, the description carries the full burden, but it does disclose one meaningful side effect: 'camera: Camera node path; creates one if omitted.' It also implies node creation in /out. However it says nothing about permissions, whether existing render configs are overwritten, or error behavior — notable gaps for a mutating setup tool.

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 one-line purpose is front-loaded and the Args list is an efficient, scannable mapping of each parameter to its meaning. Slightly mechanical but no wasted sentences.

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 6-parameter mutating tool with no annotations and no output schema, the parameter coverage is solid but the description omits what is returned (e.g., the created node path), whether prior configs are affected, and error conditions. Adequate, with clear 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 coverage is 0%, so the description must compensate, and it largely does: it explains renderer values ('karma', 'mantra'), the camera path plus auto-creation behavior, Houdini variable support in output_path, the [width, height] resolution shape, and where the ROP node name lands (/out). This is well beyond the bare schema.

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 names a specific verb and resource ('Set up a render configuration') plus the artifacts created (camera and ROP node). It is clearly a setup/creation tool, but it does not distinguish itself from nearby siblings like create_render_node or set_render_settings, which also target render configuration.

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?

There is no statement of when to use this tool versus create_render_node, set_render_settings, or create_render_node/set_render_settings combos. No prerequisites or when-not-use conditions are given, so the agent must infer routing from the name alone.

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