td_search_parameters

Find TouchDesigner operators by describing the parameter effect you need. Enter a query like 'feedback amount' or 'sample rate' to identify which operators have matching parameters.

Instructions

Find which operators have a parameter matching a description.

Useful when you know the effect you want but not which operator provides it — "feedback amount", "sample rate", "instancing".

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4/5.0

Behavior3/5

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

With no annotations provided, the description carries the burden of behavioral disclosure. 'Find' implies a read-only lookup, and the description explains the matching concept, but it does not explicitly state side-effect-free behavior, matching semantics, or query interpretation beyond examples.

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 compact and front-loaded with the core action. The second sentence adds useful context and concrete examples without any filler.

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

Completeness4/5

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

For a simple two-parameter search tool, the description provides enough context to understand its purpose and invocation. The output schema is present, so return details are not required. The only minor gap is the lack of any mention of limit behavior or result set scope.

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

Parameters3/5

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

Schema coverage is 0%, so the description must compensate. It adds useful query semantics by giving examples like 'feedback amount', 'sample rate', and 'instancing', clarifying that query is a natural-language effect description. However, it does not explain the limit parameter or how results are ordered or constrained.

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 opens with a specific verb and resource: 'Find which operators have a parameter matching a description.' This clearly distinguishes it from sibling tools like td_search_operators, which likely search by operator name, by focusing on parameter descriptions as the search target.

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

Usage Guidelines4/5

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

It gives a clear trigger for when to use the tool: 'when you know the effect you want but not which operator provides it.' This is concrete usage context, though it does not explicitly name alternatives or state when not to use the tool.

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