create_spare_parameters

Create multiple spare parameters on a Houdini node in a single batch operation, with full validation and atomic commit to prevent partial updates.

Instructions

批量 spare 参数创建(add-node-parameter-vex-tools,MUTATING)。

``parameters`` 是 list of spec dict;先全量校验、失败零部分提交。
单次 ``setParmTemplateGroup()`` 完成。响应过 ``apply_response_cap``。

Behavior4/5

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

Despite lacking annotations, the description proactively discloses critical behavioral traits: full validation before any commit ('先全量校验、失败零部分提交'), execution via a single setParmTemplateGroup() call, and response processing through apply_response_cap. This provides a solid mental model of the operation's safety and mechanics.

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 highly concise, using three short sentences to convey purpose and key execution details without redundancy. It front-loads the main action and avoids unnecessary filler.

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

Completeness2/5

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

For a batch mutation tool with no annotations or output schema, the description provides atomicity and execution details but omits essential parameter format and semantics for all fields. The undefined spec dict format and unstated roles of ctx, path, and folder make the tool under-specified.

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

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description clarifies that 'parameters' is a list of spec dicts, which helps given the schema only types it as a string. However, it does not explain the structure of the spec dicts or the meaning of ctx, path, and folder. With 0% schema description coverage, this leaves significant ambiguity.

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 clearly identifies the tool as a batch spare parameter creator ('批量 spare 参数创建'), which is distinct from the singular sibling create_spare_parameter. It also references the underlying function, making the purpose 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 word '批量' implies batch usage, but there is no explicit guidance on when to use this tool versus create_spare_parameter or set_parameters. No exclusions or alternatives are mentioned, so usage context is only implied.

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