set_parameter

Sets a parameter value on a Houdini node by specifying the node path, parameter name, and new value (int, float, string, bool, or list).

Instructions

Behavior2/5

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

With no annotations present, the description carries the full behavioral burden. It only restates that the tool sets a parameter value and lists accepted value types; it does not disclose side effects, whether setting triggers a cook, behavior on locked parameters, or how the value is applied.

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

Conciseness4/5

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

The description is compact and structured as an args block with no filler. It is easy to scan, though it is too sparse to carry full context.

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?

Given no annotations, no output schema, and a large sibling set of parameter-related tools, the description leaves important context missing including when to use this over set_parameters or set_expression, and what happens after the value is set.

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%, so the description must compensate. It adds minimal gloss for the three parameters, especially the accepted value types for 'value, but it does not explain node_path formatting, parameter name syntax, or value coercion behavior.

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

Purpose4/5

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

The description states a clear action and resource: 'Set a parameter value.' It is not tautological and implies a mutating counterpart to get_parameter, though it does not explicitly distinguish itself from set_parameters or set_expression.

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 guidance on when to use this tool versus sibling tools such as set_parameters, set_expression, link_parameters, or revert_parameter. No context about prerequisites, restrictions, or typical use cases is provided.

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