center-layers

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

No annotations are provided, so the description must fully disclose behavioral traits. However, it fails to mention important behaviors such as whether centering affects position or anchor point, any prerequisites (e.g., layers must be selected for selectedOnly), or the effect on layer transformations.

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, concise sentence that immediately conveys the tool's functionality. It is front-loaded and contains no unnecessary words.

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?

Despite having multiple modes and five parameters, the description does not explain how parameters interact (e.g., precedence when both layerIndex and selectedOnly are set) or the return value. More detail is needed for an agent to correctly invoke the tool.

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% coverage, so the schema already documents all parameters. The description adds no additional meaning beyond restating the modes. This meets the baseline of 3 but does not exceed it.

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 'center' and the resource 'layers in a composition', specifying three distinct modes: one layer, selected layers, or all layers. This distinguishes the tool from siblings, which are mostly effect-related.

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 implies the tool is for centering layers, but it does not provide explicit guidance on when to use it versus alternatives, nor does it mention when not to use it. No siblings perform centering, so the lack of explicit context is acceptable but not ideal.

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