save_openscad

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

Given no annotations, the description carries full burden. It discloses one behavioral trait (no CLI invocation) but fails to mention whether the file is overwritten, required permissions, or what happens on default path. Minimal disclosure for a mutation-like save operation.

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 concise sentence, easy to parse. It front-loads the core action and distinguishing feature. However, it could be slightly expanded with parameter context without losing conciseness.

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 one optional parameter and an output schema, the description is too sparse. It does not explain the return value (though output schema exists, its contents are not described in the description), nor does it cover typical use cases or edge cases like overwrite behavior.

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?

The input schema has one parameter (output_path) with 0% schema description coverage. The description does not mention the parameter at all, providing no guidance on its purpose, format, or behavior (e.g., relative vs absolute path, file extension handling).

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?

Description clearly states the tool saves the current OpenSCAD source, and explicitly notes it does not invoke the CLI. The verb 'save' and resource 'current OpenSCAD source' are specific, and among siblings, only this tool deals with OpenSCAD, distinguishing it well.

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?

No guidance on when to use this tool versus alternatives like save_drawing or export_model. The mention of 'without invoking the CLI' hints at an alternative that does invoke it, but no explicit when-to-use or when-not-to-use instructions are given.

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