game_procedural_mesh

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

No annotations beyond title; description omits side effects like creating a new node or attaching the mesh. It does not disclose whether the operation is destructive or requires permissions, leaving significant behavioral ambiguity.

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 sentence, making it concise, but it is under-specified. While it avoids verbosity, it fails to include essential details, reducing its practical value.

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 complexity of procedural mesh generation (6 parameters, no output schema), the description is incomplete. It does not explain the return value, error states, or how the mesh is integrated into the scene, leaving critical gaps.

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 baseline is 3. The description adds no extra meaning beyond the schema, such as explaining the relationship between vertices, indices, normals, and UVs.

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 verb 'Generate' and the resource 'meshes' along with the method 'via ArrayMesh'. It distinguishes from siblings like game_mesh_instance which deals with existing meshes, though it doesn't explicitly exclude related tools like game_terrain.

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 offers no guidance on when to use this tool versus alternatives, such as when to create a mesh procedurally versus using a pre-made mesh. No exclusions or prerequisites are mentioned.

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