reinit_niagara_system

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

There are no annotations to rely on, so the description must disclose behavioral traits itself. It only says what the tool does, not any side effects, prerequisites, or whether the operation is reversible. For a potentially mutating operation (reinitialize), it should at least mention that it resets to initial state or similar, but it does not.

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 a single, lean sentence that directly states the purpose with no fluff or redundancy. It is appropriately front-loaded and every word contributes to meaning.

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?

Given the absence of annotations and output schema, the description must carry more weight. It is too brief to fully explain the tool's behavior, usage context, or relationship to similar tools. For a simple tool with one parameter, it might be minimally acceptable, but the presence of 'reset_niagara_system' as a sibling raises ambiguity. The description does not offer enough to resolve that, making it incomplete.

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?

The input schema covers 100% of the parameter descriptions, including 'Actor with Niagara component', so the schema already explains the parameter. The tool description adds no new parameter information beyond implying the actor is the target. Per the rubric, baseline 3 is appropriate when schema coverage is high, and the description does not add value beyond that.

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 action ('Reinitialize') and the resource ('a Niagara system on an actor'). It is specific enough to distinguish it from general tools like 'spawn_niagara_*' or 'set_niagara_*', but it does not explicitly differentiate from the sibling tool 'reset_niagara_system', which could be similar. Thus it is clear but lacks explicit differentiation.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or situations where a different tool would be more appropriate. The only context is implicit in the purpose, but there is no explicit usage guidance.

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