godot_create_tilemap_layer

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

Annotations are all false, so the description carries the behavioral burden. It only says 'Add,' which implies mutation, but it doesn't disclose whether the active scene is mutated, whether the change persists without saving, or whether the TileSet is referenced or copied. This is minimal disclosure for a mutating tool.

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 front-loaded sentence with no filler, making it very easy to parse. However, its brevity comes at the expense of necessary usage and prerequisite context, so it is not maximally appropriate in size.

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?

In a library with over a hundred tools, one sentence is insufficient. It lacks guidance on scene prerequisites, relationship to godot_set_tilemap_cells, side effects on the active scene, and whether the TileSet binding is optional. An output schema may cover return values, but the invocation context is still 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 tool description adds no meaning for name, tile_set_path, or parent_node_path beyond the schema. With reported schema description coverage at 0%, the description was expected to compensate but does not; the only hint is 'TileSet binding,' which doesn't explain the optionality or path semantics.

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 uses a specific verb ('Add') and resource ('TileMapLayer node') and adds the distinguishing qualifier 'with TileSet binding.' This separates it from generic node creation and from tilemap cell manipulation, though it doesn't explicitly name sibling alternatives.

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?

There is no guidance on when to use this tool versus godot_create_node, godot_instantiate_scene, or godot_set_tilemap_cells. It also omits prerequisites such as whether a scene must be open or whether the TileSet binding is required.

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