load_sprite

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states 'load a sprite' without explaining whether this modifies the scene file, requires the scene to be open, overwrites existing textures, or has other side effects. This leaves critical behavioral aspects hidden.

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 clear sentence with no filler or redundancy. It is appropriately sized and front-loaded, making it easy to parse quickly. Every word earns its place.

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 4 required parameters, no annotations, and no output schema, the description is too minimal. It does not explain the operation's lifecycle (e.g., persistence, prerequisites, effect on existing sprite), nor what the agent can expect after loading. While the schema covers parameter meanings, the tool's overall behavior and preconditions are undocumented.

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 has 100% description coverage, so each parameter is already clearly documented. The tool description adds no additional parameter semantics beyond the schema. Per guidelines, baseline 3 is appropriate when schema coverage is high and the description does not compensate with extra details.

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 (load) and the target resource (a sprite into a Sprite2D node). It is specific and distinguishes from sibling tools like add_node or set_node_property, which serve different purposes. The context is unambiguous for an agent.

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, side effects, or contrast with similar operations like assigning a texture via node properties. An agent must infer usage solely from the tool name and parameters.

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