create_spare_parameters

Batch-create multiple spare parameters on a Houdini node in one call. Optionally wrap them in a folder tab with configurable folder type.

Instructions

Batch-create multiple spare parameters in one call, optionally in a folder tab.

Args: node_path: Node path. parameters: List of parameter specs. Each dict has keys: parm_name (str), parm_type (str: "float"/"int"/"string"/"toggle"/"menu"), label (str), default_value (optional), min_val (optional), max_val (optional). folder_name: If provided, wraps all parameters in a named folder tab. folder_type: Folder style: "Tabs", "Collapsible", or "Simple".

TDQS

A3.9/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full burden. It discloses the creation behavior, batch nature, folder wrapping option, and parameter types. However, it does not reveal what happens on duplicate parameter names, whether existing parameters are replaced, or what side effects or errors may occur.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short, front-loaded with the core purpose, and uses a clean Args list with no filler. Each line adds necessary information about argument semantics.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is sufficient to construct a call because all parameters and nested spec keys are documented. However, with no annotations and no output schema, it omits return behavior, error conditions, and prerequisites such as node_path validity or duplicate-name handling, leaving some gap for an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

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, and it largely does. It explains parameters as a list of spec dicts with keys and types, clarifies folder_name behavior, and enumerates folder_type values. Node_path is thinly described as 'Node path', but the nested parameter spec detail is the main value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear action: 'Batch-create multiple spare parameters in one call', with an optional folder tab. The batch aspect distinguishes it from the sibling create_spare_parameter, so the tool's purpose is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'Batch-create multiple spare parameters in one call' implies the tool is for multi-parameter creation, and a singular sibling exists. However, it never explicitly states when to prefer this over create_spare_parameter, nor does it mention exclusions or prerequisites beyond the arguments.

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