configure_camera

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

With no annotations, the description carries the full burden of behavioral disclosure. It does not state whether the camera must already exist, whether unset parameters are left unchanged or reset to defaults, or what side effects occur. It only says 'Configure,' which implies mutation but provides no detail about the operation's behavior.

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 a clear one-line purpose followed by a parameter list. There is no redundant prose. It earns its place, though it could be slightly more structured with grouping of related optical parameters.

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 seven parameters, no output schema, and no annotations, the description is incomplete. It does not explain prerequisites, default behavior for null values, return values, or the effect of each parameter on the final rendered image. An agent would need additional context to invoke it correctly in all cases.

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 0%, so the description must compensate. It does list all seven parameters with brief explanations, adding meaning such as 'Focal length in mm' and 'Enable depth of field.' However, it omits units for focus_distance, clip_start, and clip_end, and does not explain valid ranges or the relationship between fstop and depth_of_field.

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 states a specific verb and resource: 'Configure camera optical properties.' This clearly identifies the tool's function and distinguishes it from camera creation, framing, and viewport tools. However, 'configure' is somewhat generic and could be more explicit about the fact that it modifies an existing camera.

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 like create_camera, set_camera_to_view, or setup_studio_camera. There are no explicit conditions, exclusions, or references to sibling tools. The usage context is only implied by the phrase 'optical properties.'

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