create_chop_node

Create a new CHOP node in Houdini by specifying a parent path and chop type, with an optional name parameter to control node identification.

Instructions

Create a new CHOP node.

C2.4/5.0
Behavior2/5

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

No annotations are supplied, so the description carries the full behavioral burden, and it discloses almost nothing beyond the implicit fact that a mutation occurs. It does not say whether the parent path must already exist, whether an error is raised on duplicate names, what happens if name is omitted, or what the call returns.

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

Conciseness3/5

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

The single sentence is front-loaded and free of padding, but its brevity reflects under-specification rather than economy. There is room to add routing and parameter context without bloat.

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 mutation tool with zero annotation coverage, no output schema, and no schema descriptions on any of its three parameters, this one-line description is not sufficient for an agent to call it confidently. At minimum it should state the parent-path expectation and the chop_type format.

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?

Schema description coverage is 0% across three parameters, so the description needed to compensate and does not: it says nothing about parent_path formatting, what a valid chop_type string looks like, or how the optional name defaults. The parameter names are suggestive but the description adds no meaning beyond them.

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

Purpose3/5

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

The description gives a specific verb ("Create") and a specific resource ("CHOP node"), so the basic intent is clear. However, it is essentially a restatement of the tool name and offers no differentiation from siblings such as create_node or create_cop_node, leaving the agent to infer what distinguishes a CHOP node creation from a generic node creation.

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

Usage Guidelines2/5

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

There is no when-to-use guidance, no mention of prerequisites such as an existing parent network, and no pointer to alternatives like create_node or the other typed create_* siblings. The agent must guess the context in which this tool is the correct choice.

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