scene-add-plain-objects

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

No annotations exist, and the description does not disclose any behavioral aspects beyond the basic action. It fails to mention side effects (e.g., scene modification in-place), prerequisites, or post-conditions, which is insufficient for a mutation 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 7-word sentence, making it concise but overly minimal. It lacks structured information such as usage context or parameter hints, which would benefit from additional sentences.

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 tool's complexity (two required parameters, nested object structure, no output schema, and mutation semantics), the description is insufficient. It does not explain the concept of 'plain objects', how they interact with the scene, or what the agent should expect after 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?

With schema description coverage at 50%, the tool description adds no additional meaning to parameters. It does not explain the 'objects' array structure or the purpose of 'sceneId' beyond what the schema provides, missing an opportunity to compensate for incomplete schema descriptions.

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 'Add' and resource 'plain objects to the scene', aligning with the tool name. It distinguishes from sibling add tools like scene-add-game-objects by specifying 'plain objects', though it could be more explicit about what defines a plain object.

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 guidance is provided. The description does not indicate when to use this tool versus alternatives such as scene-add-game-objects or scene-add-editable-tilemap, leaving the agent guessing about context.

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