select_actors

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

The description mentions replace_selection parameter indicating behavior, but no annotations exist. It lacks disclosure of side effects, error handling, or whether selection is cleared before adding. Some behavioral transparency is provided, but not comprehensive.

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

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

The description is relatively concise, but duplicates parameter documentation within the description field rather than using a separate structure. Could be more streamlined.

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

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

Despite having an output schema, the description does not mention return value or errors. Provides essential parameter info but lacks details on edge cases, outcomes when actors not found, or interaction with other tools.

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

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

Schema has only one string parameter 'kwargs' with no description. The description adds meaning by listing supported sub-parameters (actor_labels, replace_selection) and format hints, but does not fully specify formats (e.g., exact JSON syntax). Schema coverage is 0%, so description partially compensates.

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

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

The description clearly states the tool selects one or more actors in the Unreal Editor, which is a specific verb+resource. It distinguishes from siblings like delete_actor or modify_actor.

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

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

No guidance on when to use this tool versus alternatives. Does not mention prerequisites, context, 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.
