cam_create_physical

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

Annotations already communicate readOnlyHint=false and destructiveHint=true, and the description's 'Create' behavior is consistent with that. The description adds the list of adjustable camera attributes, but does not disclose side effects, defaults, or whether a camera object is added to the scene. No annotation contradiction.

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 compact and front-loaded with the action and resource, followed by a concise parameter summary. The bilingual repetition is reasonable for the audience, and there is no filler, though the parameter list is somewhat redundant with the schema.

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 creation tool with no output schema and a destructive annotation, the description gives enough to understand the basic operation. However, it omits usage context relative to cam_create, default behaviors, and any prerequisites or side effects, leaving moderate gaps for an agent deciding how to invoke it correctly.

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 for all 9 parameters, so the schema already documents each field. The description provides a high-level summary of parameter categories but adds no additional meaning, constraints, or format details beyond the schema.

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?

States a specific verb 'Create' plus the resource 'Physical Camera' and enumerates the main configurable settings (focal length, f-stop, shutter, ISO, DoF, FOV). This clearly distinguishes it from camera query/set tools, though it does not explicitly differentiate from the sibling cam_create.

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 guidance on when to use this tool versus alternatives such as cam_create, cam_set, or other camera creation tools. The description implies usage through the name but provides no exclusion conditions or context for choosing it.

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