design_list_trace_presets

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

No annotations are provided, but 'List available' clearly signals a read-only enumeration, and the description adds useful context that each preset configures edge detection, contour extraction, and spline fitting for a material type. It does not mention return format or side effects, so it is helpful but not fully transparent.

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?

Two compact sentences, front-loaded with what is listed and what a preset means. Every sentence contributes and there is no waste.

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 zero-parameter list tool with no output schema, the description is sufficient to know what is being enumerated and why presets differ. It omits the shape of the returned preset data and how a preset is consumed by tracing tools, which is a minor gap.

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 tool takes zero parameters, so there are no parameter semantics to explain. The baseline score of 4 is appropriate for this case.

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?

States a specific verb and resource ('List ... threshold presets') and scopes it to image tracing; the second sentence explains what a preset does. It does not explicitly name trace-operation siblings, so sibling differentiation is only implied.

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?

Implies this is a discovery step before tracing, but never says when to use it versus design_trace_edges, design_trace_contours, or the other trace tools, nor what to do with the presets. No exclusions or alternatives are given.

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