create_coupled_temp_disp_step

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

No annotations are provided, so the description carries the full burden of behavioral disclosure, and it discloses nothing beyond the creation action. It does not mention that this mutates the named model (model_name), how previous_step chains onto prior analysis, what happens on name conflicts, or that solver increment parameters control convergence behavior.

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 with the verb and object front-loaded and no filler. However, this is under-specification rather than disciplined conciseness: for a 9-parameter tool it needs to earn its minimalism with more context elsewhere, which it does not.

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 9 parameters, zero schema descriptions, no annotations, and roughly ten sibling step-creation tools to disambiguate, a one-sentence description is far short of what an agent needs to invoke this tool correctly. The existence of an output schema covers return values only and does not compensate for the missing parameter, behavioral, and selection context.

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% across 9 parameters, and the description adds no parameter meaning whatsoever. Terms like max_inc, min_inc, initial_inc, time_period, and previous_step remain ambiguous in an Abaqus context (e.g., max_inc could be read as maximum increment size vs. maximum number of increments), and nothing compensates for the missing schema descriptions.

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 specific verb ('Create') plus a precisely named resource ('Coupled Temperature-Displacement step'), so the action and target are unambiguous. The physics-specific step type is inherently distinctive among the many sibling step tools (static, modal, heat transfer, dynamic implicit, etc.), though the description never explicitly contrasts it with them.

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 single sentence offers no guidance on when to choose this tool over sibling alternatives like create_heat_transfer_step or create_static_step. There is no mention of prerequisites, model setup required for a coupled thermal-displacement analysis, or when this step type is appropriate versus others.

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