Create Layer

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

The description does not disclose any behavioral traits beyond the annotation (readOnlyHint=false). It omits details such as whether duplicate layer names are allowed, whether the new layer becomes current, or any side effects. With the annotation already indicating a write operation, the description adds no additional transparency.

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 very short but lacks informative content. It does not front-load key behavioral details or use its space effectively. A more concise description would still include necessary context.

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 (CAD-specific parameters) and the presence of many sibling tools, the description is insufficient. It does not mention return values despite an output schema, nor does it explain CAD-specific concepts like ACI color codes or the effect on drawing state.

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 coverage is 100%, so the baseline is 3. The description adds no extra meaning beyond stating that properties can be specified, which is already implied by the parameters in 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?

The description uses the verb 'Create' with the resource 'layer', specifying that it can set properties. This clearly distinguishes it from sibling layer tools like layer_delete, layer_modify, or layer_set_current.

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 is provided on when to use this tool versus alternatives. For example, there is no mention that layer_create is for new layers while layer_modify updates existing ones, nor any exclusions or prerequisites.

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