set_tile_cell

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

With no annotations, the description is the only source of behavioral insight. It states the target type but omits any details about side effects, requirements, or error behavior, leaving significant ambiguity for a mutation operation.

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?

A single, focused sentence that states the action and object clearly. It is concise and free of unnecessary detail.

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?

The description is drastically under-specified for a tool with 10 parameters and no output schema or annotations. It lacks critical information about parameter meanings, required setup, expected results, and failure modes, making it nearly impossible for an agent to invoke correctly without external knowledge.

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 description provides no parameter explanations, and the schema is nearly empty (only projectPath has a description). The agent is left to infer the meaning of x, y, sourceId, atlasX, atlasY, etc., which is insufficient.

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 identifies the action ('set'), the target resource ('TileMap or TileMapLayer cell'), and the mechanism (Godot's native API), making its purpose unmistakable and distinct from sibling tools like inspect_tilemaps or set_node_property.

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 usage context is provided; the description doesn't mention when to use this tool instead of alternatives like set_node_property, or any prerequisites such as the scene being open.

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