create_render_node

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It says the node is created in /out, but does not mention whether the renderer starts, whether name collisions are handled, what the tool returns, or any side effects beyond node creation.

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 purpose is front-loaded in one clear sentence, followed by a compact argument list. It is appropriately sized, though the 'name' line adds little value beyond the schema's parameter name.

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 simple four-parameter creation tool, the description covers the purpose, location, and input semantics adequately. However, with no annotations or output schema, it leaves gaps around expected return values, failure behavior, and whether the created node is automatically rendered or cooked.

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%, and the description compensates well by listing valid renderer values and clarifying semantic roles like 'Camera node path' and 'Output file path.' Only 'name: Node name' is largely redundant with the 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 states a specific verb and resource: 'Create a new render (ROP) node in /out.' This clearly identifies what the tool does and where, and distinguishes it from generic node creation or render configuration siblings like create_node or setup_render.

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 guidance about when to use this tool versus alternatives. Siblings such as setup_render, start_render, and render_node_network suggest related workflows, but the description does not explain where create_render_node fits or when not to use it.

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