loft_sketches

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

There are no annotations provided, and the description does not disclose any behavioral traits. The agent has no information about side effects, permissions, or constraints beyond the basic parameter names.

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 extremely short (5 words), but under-specification is not conciseness. It fails to provide essential information, so it does not earn points for brevity.

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 the tool has 3 parameters, no output schema, and no annotations, the description is severely incomplete. It does not explain the lofting process, prerequisites (e.g., multiple sketches needed), or expected results.

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 description adds no value beyond the input schema. While the schema has descriptions for 'sketch_names' and 'body_name', the description itself does not explain their role in the loft operation. The 'ruled' parameter's purpose is unclear.

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 'FreeCAD tool: loft_sketches' is a tautology, simply restating the tool name. It does not specify what the tool does (e.g., creates a solid by lofting between sketches). This is the lowest score for purpose clarity.

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 is provided on when to use this tool versus alternatives like sweep_sketch or revolve_sketch. The description gives no context for appropriate usage scenarios.

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