generate_model_java

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

With no annotations, the description carries the behavioral disclosure burden. It discloses that COMSOL is not required for generation, that the output is only source code, and that compilation to an .mph still requires COMSOL. It could mention file-overwrite behavior, but the core operational constraints are clearly stated.

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 concise and well-structured: a clear first sentence, a self-contained usage workflow, and supporting commands. Every sentence contributes useful information, though the two references to COMSOL being needed for compilation are slightly repetitive.

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 code-generation tool with no annotations and a low-coverage schema, the description covers the essential operational context: where to use it, what it creates, what the next steps are, and what the `spec` parameter controls. With an output schema already present, the lack of return-value detail is acceptable, though model_version remains a 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?

Schema description coverage is 0%, so the description must compensate. It adds meaning for the `spec` parameter by listing what it may carry, and the compile commands imply the roles of `filepath` and `class_name`. However, `model_version` is not mentioned at all, and filepath/class_name are only implied rather than explicitly described.

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 and deliverable: generate a standalone, compilable COMSOL Java model source file. It also distinguishes itself from sibling tools by emphasizing that it works without COMSOL and produces source code rather than an .mph file.

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?

It clearly explains when to use the tool: on a COMSOL-less machine to prepare a Java model, then compile it on a COMSOL machine. It even includes concrete commands. It does not explicitly name alternatives or state when not to use it, but the intended workflow is unambiguous.

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