get_component_property

Retrieve a specific property value from an entity's component by supplying entity ID, component type, and property path. Enables direct access to component data for automation.

Instructions

Get a property value from a component on an entity.

Args: entity_id: The entity ID. component_type: Component type name (e.g. 'Transform'). property_path: Property path using '|' separator (e.g. 'Controller|Configuration|Model Asset').

Tool call template

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

TDQS

A3.7/5.0
Behavior3/5

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

There are no annotations, so the description carries the behavioral burden. It communicates the read-only nature through the verb 'Get' and explains the property path separator, but it does not disclose error behavior, prerequisites like entity existence, or what happens when a property path is invalid.

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, front-loaded with the main purpose, and uses a clean Args block. Every sentence contributes useful information without redundancy.

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 getter with an output schema, the description covers the parameters, path format, and component type adequately. It lacks explicit comparison to sibling tools and does not mention failure scenarios, but these are minor gaps given the tool's simplicity.

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

Parameters5/5

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

Schema description coverage is 0%, but the description fully compensates by documenting all three parameters with meaningful explanations and concrete examples, including the '|' separator format for property_path and the 'Transform' example for component_type.

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 clearly states the action: 'Get a property value from a component on an entity,' with a specific verb and resource. It is easy to distinguish from the sibling set_component_property, but it does not explicitly name or contrast any sibling tools.

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 about when to use this tool versus alternatives such as get_entity_components or set_component_property. The description only explains parameters, leaving the agent to infer the appropriate context.

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