catia_new_drawing

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

Annotations already indicate mutation (readOnlyHint false). The description adds that it optionally sets drafting standard and paper size, but doesn't disclose return value or side effects like whether it activates the document. Lacks behavioral detail beyond schema.

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?

Two concise sentences with no fluff, main purpose front-loaded, and every word earns its place.

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 simple creation tool, it's mostly complete, but it doesn't mention return value or whether the new document becomes active. With no output schema, this is a gap that could leave the agent uncertain about the result.

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 covers all three parameters with descriptions. The description adds that standard and paper_size apply to the first sheet, which is useful context beyond schema. Also confirms they are optional, though defaults already imply that.

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?

States a specific verb ('Create') and resource ('CATDrawing document'), and mentions optional settings for standard and paper size. Clearly distinguishes from sibling tools like catia_drawing_add_sheet or catia_new_part by the document type.

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 description doesn't explicitly discuss alternatives or when not to use this tool. However, the name and purpose make it obvious that it's for creating new drawing documents, distinct from creating parts or products. No explicit exclusion guidance is provided.

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