create_boundary_group

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

The description's 'Create' matches the annotations' non-readOnly, non-idempotent hints, so there is no contradiction. However, it adds no behavioral detail beyond the creation claim, such as duplicate-name handling, return value, or whether the group is created empty. Because the annotations provide little safety context, this is adequate but not rich.

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 compact, action-first, and includes the key parameter explanation without filler. The bilingual restatements add some redundancy but are short and may improve clarity for the intended audience.

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 simple one-parameter create tool with no output schema, the description covers what the tool does, when it is used, and what its only parameter means. It could mention return values or duplicate behavior, but those gaps are minor at this complexity level.

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?

With 0% schema description coverage, the description must carry parameter meaning. The 'Args' section defines 'name' as the boundary group name with a Chinese equivalent, which is minimal but sufficient for the single required 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 uses a clear verb and resource ('Create a boundary condition group') and adds a useful explanation that boundary groups collect supports/links for stage-controlled activation/deactivation. It does not explicitly compare itself with sibling creators like create_load_group or create_structure_group, so it stops short of full sibling differentiation.

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 construction-stage context gives a clear signal for when this tool is relevant: when boundary conditions need to be grouped for activation/deactivation together. It does not list exclusions or name alternatives, but the use case is specific enough for an agent to select it correctly.

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