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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. 'Add a Sprite2D' implies a mutation, but it does not describe side effects such as whether the scene is saved, whether existing nodes are affected, error behavior, or whether it requires an active project. The description is too sparse to be behaviorally transparent.

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, front-loaded with the action and object, and contains no wasted words. It is concise and to the point, though the terseness sacrifices potentially important context that would improve usability.

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 tool has five parameters, two required, no output schema, and no annotations. The description only covers the basic purpose and fails to address side effects, return values, or the context in which this tool should be used. For a mutation tool with this complexity, the description is incomplete and could lead to incorrect invocation.

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 description coverage is only 20% (only projectPath has a description), and the tool description adds minimal value beyond that. It clarifies that texturePath should be project-relative, which is helpful, but it does not explain scenePath, parentPath, or nodeName. Given the low schema coverage, the description insufficiently compensates for the missing parameter 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 clearly states the action ('Add a Sprite2D') and the key constraint ('using a project-relative texture path'), which is specific enough to distinguish it from generic siblings like add_node. However, it does not explicitly mention the target scene or that it operates on a scene tree, leaving slight ambiguity about the context.

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, no prerequisites (e.g., project must be open, scene must exist), and no exclusions. It only states what it does without contextualizing when it is the appropriate choice.

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