List Layers

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

No annotations are provided, so the description carries the full burden. It accurately indicates a read-only listing operation and enumerates the returned properties, but does not disclose edge cases (e.g., empty drawings, invalid files, or performance behavior). The behavior is straightforward enough that a score of 3 reflects adequate but not deep 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 a single, efficient sentence that front-loads the core action and lists the output contents in parentheses. Every word contributes meaningful information, with no filler or repetition.

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 low complexity, one parameter, and an existing output schema that already defines the return structure, the description covers the essential calling context: what the tool does and what data it returns. It omits direct usage guidance, but the operational completeness is strong.

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 0% and the file_path parameter has no schema description, so the description must compensate. It does so by establishing that the tool operates on a DXF drawing, implicitly clarifying that file_path is the path to that drawing. While explicit path format details are absent, this is sufficient for a single obvious parameter.

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 a specific verb and resource ('List all layers in a DXF drawing') plus the properties returned (name, color, linetype, lineweight, status, entity count). This distinguishes it from sibling tools like list_blocks, which target a different resource type.

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 gives no explicit guidance on when to prefer this tool over alternatives. Siblings like list_blocks or query_drawing_entities are not mentioned, and no conditions or exclusions are provided. Usage context is only implied by the tool's name and basic function.

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