rc_get_property

Retrieve any UObject property directly through Remote Control, bypassing the Python bridge. Provide the full object path and property name.

Instructions

Read a UObject property directly via Remote Control (no Python bridge).

object_path is a full object path, e.g. '/Game/Maps/Test.Test:PersistentLevel.PointLight_1.LightComponent0'.

Behavior3/5

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

No annotations provided, so description carries full burden. It states 'Read' implying no side effects, but doesn't cover permissions, error cases, or output details. Basic but adequate.

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 terse sentences: first defines purpose, second provides concrete example. No redundant information.

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?

Despite simplicity, description covers core purpose and parameter example. Missing safety or error details, but output schema likely covers return structure.

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 description coverage is 0%. The description includes an example for object_path, clarifying format, but property_name is not explained. Partial help.

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?

Description clearly states 'Read a UObject property directly via Remote Control', specifying a precise verb and resource. It distinguishes from sibling tools like rc_set_property (write) and rc_call_function (call).

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?

No explicit guidance on when to use this tool vs alternatives. The description does not mention conditions, prerequisites, or when not to use it.

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