Create control panel

create_control_panel

Adds custom parameter controls (sliders, toggles, menus, RGB, pulse) to a COMP and binds them to node parameters for real-time adjustment of a generated TouchDesigner system.

Instructions

Expose live controls on a COMP: append custom parameters (sliders, toggles, menus, RGB, pulse) and bind them to node parameters so the artist can drive a generated system in real time. Point comp_path at a system container and list the controls; use each control's bind_to to wire it to one or more 'nodePath.parName' targets.

Tool call template

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

A4.2/5.0
Behavior4/5

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

The description discloses important side effects beyond the annotations: it appends custom parameters and switches each bind_to target to expression mode. This is valuable behavioral context. The annotations (readOnlyHint=false, destructiveHint=false) are consistent with the description, so no contradiction.

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?

Two dense, information-rich sentences with no filler. The first sentence states the purpose and capabilities; the second gives actionable instruction. This is an excellent example of front-loaded, economical writing.

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?

Given the rich input schema and absence of an output schema, the description adequately covers the core effect (append controls, bind to parameters, switch to expression mode) and usage context. It does not dive into failure modes or edge cases, but those are not required for this level of complexity.

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?

The input schema already provides 100% coverage with detailed descriptions for all parameters and nested control properties. The description mostly restates comp_path and bind_to without adding new syntax or semantics, so it earns the baseline score for schema-heavy tools.

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 states the action—expose live controls on a COMP by appending custom parameters—and the resource (a COMP). It also distinguishes itself from generic parameter tools by describing binding to node parameters, which is a specific, differentiating behavior.

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 provides a clear use case ('drive a generated system in real time') and concrete directives: point comp_path at a system container and use bind_to to wire controls. It doesn't explicitly name alternatives or exclusions, but the context is strong enough for an agent to decide when to invoke it.

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