create_section_from_properties

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

It discloses a useful behavior: sec_property is option and, if omitted, a basic list with Area, Ix, Iy, Iz is auto-generated. With all annotations false, the description carries the safety/behavior burden, yet it does not mention side effects such as overwriting an existing section, units, or failure behavior.

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 docstring is structured and front-loaded with the action, followed by a concise Args list. The bilingual duplication adds length but every line carries meaning; there is no filler.

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 creation tool with no output schema, the description covers the core action and all parameter meanings, plus the option-behavior. Missing details include units, name-collision behavior, and the full contract of the 29-item property list, so completeness is adequate but not thorough.

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%, and the description compensates by defining each parameter including Chinese meanings, and explains sec_property's up-to-29 list and default fallback. It does not clarify the exact relationship between the individual required fields and a supplied sec_property, nor units, so it is not perfect.

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 opens with a specific action ('Create a section') and narrows the method to 'pre-calculated properties', which sents it apart from geometry-based section tools like create_polygon_section. It does not explicitly name sibling tools, so differentiation is partial rather than fully explicit.

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 phrase 'directly from its pre-alculated properties' implies the intended context: when section properties are already known rather than computed from geometry. However, there is no explicit guidance on when to choose this over siblings like create_section or update_section_property, and no exclusions.

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