model_load

Load a COMSOL model from a .mph file to make it available for simulation or analysis. Optionally set it as the active model for subsequent operations.

Instructions

Load a COMSOL model from a .mph file.

Args: file_path: Absolute or relative path to the .mph model file set_current: Whether to set this as the current active model (default: True)

Returns: Model info including name, file path, and version, or error message

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A3.8/5.0
Behavior3/5

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

With no annotations, the description provides basic behavioral info: it loads a file and returns model info including name, path, version, or error. However, it does not disclose failure modes (e.g., file not found, invalid format) or side effects (e.g., overriding current model).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise, with 4 lines total. The key purpose comes first ('Load a COMSOL model from a .mph file'), followed by structured argument details and return info. No redundant or irrelevant sentences.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simple nature of the tool (2 parameters, no output schema), the description covers the main operation, arguments, and return format. Minor gaps include error handling and dependencies (e.g., requires COMSOL connection), but overall it is sufficient for selection and invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description compensates by explaining file_path as 'Absolute or relative path to the .mph model file' and set_current as 'Whether to set this as the current active model (default: True)'. This adds meaningful context beyond the schema's type and title.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Load a COMSOL model from a .mph file' with a specific verb and resource. It distinguishes from sibling tools like model_create (new) and model_clone (clone existing) by focusing on loading an existing file.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives. It does not mention prerequisites like needing a running COMSOL session or connected instance, nor does it advise against use in certain scenarios.

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