compare_layout_styles

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. It implies a read-only comparison but doesn't state that explicitly, nor does it mention side effects, return format, or whether it modifies anything. This is a significant gap.

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 with no filler. It is front-loaded with the key action and object. No redundancy or unnecessary detail.

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?

Although an output schema exists, the description doesn't mention what the comparison results look like or any prerequisites (e.g., whether the diagram must exist, whether the layout styles are pre-defined). The tool is simple, but the description leaves important details about behavior and output to inference.

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 schema has zero coverage for the single parameter diagram_id, and the description only mentions 'a diagram' without explaining the parameter's meaning or constraints. The parameter name is self-explanatory, but the description adds no value beyond the schema. A description should compensate for the lack of schema docs, but it doesn't.

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 clear verb ('compare') and resource ('auto-layout styles' affecting a diagram). It is distinct from siblings like auto_layout_diagram and list_layout_styles, though it doesn't specify what aspect of the styles is compared (e.g., visual, metrics). This is adequate but not maximally precise.

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?

There is no guidance on when to use this tool versus alternatives. It doesn't mention that it should be used for previewing before applying a layout, or contrast it with auto_layout_diagram or list_layout_styles. The agent is left to infer context.

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