create_set_by_edges

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

No annotations are provided, so the description carries the full behavioral disclosure burden. It only says 'Create a set,' which implies mutation, but it does not explain overwrite behavior, persistence, assembly vs. part scope, or validation of edge indices.

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 front-loaded sentence with no filler. Every word contributes to stating the tool's core action and target resource.

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 tool with five parameters, zero schema descriptions, and no annotations, this description is under-specified. It omits when to use it, how to supply edge indices, what model_name and timeout do, and what behavior to expect beyond creating a set.

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 description coverage is 0%, so the description must compensate. It loosely maps 'edges' to edge_indices and 'instance' to instance_name, but it adds no meaning for timeout or model_name, and it does not clarify the expected format or semantics of edge_indices beyond the bare schema titles.

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 specific verb ('Create') and a specific resource ('a set from edges of an instance'). This clearly distinguishes it from sibling tools like create_set_by_face and create_set_by_vertices, which operate on different geometric entities.

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 that this tool is for selecting edges rather than faces or vertices, but it never explicitly says when to use it or when to prefer alternatives. There are no prerequisites, exclusions, or comparisons with the other set-creation siblings.

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