game_3d_effects

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

The description only indicates creation, but lacks details on side effects, permissions, or any constraints. Annotations provide no read/write hints, so the description carries the burden but fails to disclose behavioral traits beyond the basic action.

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 exceptionally concise, single-sentence, and front-loaded with the key action and objects. Every word adds value with no redundancy.

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?

For a tool with 5 parameters and no output schema, the description is minimal. It covers the core purpose but omits details like when to use each effectType or how the tool integrates with the scene. An average score reflects adequate but not comprehensive completeness.

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 coverage is 100%, so the description adds no new parameter meaning beyond listing the effect types. Baseline 3 is appropriate; the description does not enhance understanding of the parameters.

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 (Create) and the specific resource types (ReflectionProbe, Decal, FogVolume). It distinguishes the tool from siblings by specifying unique 3D effect types not covered by other tools.

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 (e.g., game_environment, game_gi). The description does not mention prerequisites or preferred scenarios.

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