v1.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It only states the basic operation without mentioning side effects (e.g., whether it overwrites existing solids), prerequisites (e.g., profiles must be planar), or constraints. This is insufficient for a creation tool.
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 that efficiently conveys the core purpose. It is front-loaded and contains no fluff. However, it could be slightly improved by incorporating key parameter hints 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?
Given the complexity of the operation (lofting between multiple 2D profiles) and the lack of output schema and annotations, the description is incomplete. It does not explain profile requirements (closed?, 2D?), behavior on invalid input, or return value. More details are needed for confident invocation.
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 coverage is 100% with descriptions for all 4 parameters, so the baseline is 3. The tool description adds no additional meaning beyond the schema, neither clarifying parameter relationships nor providing example values or formatting details.
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 clearly states 'Create a lofted solid between two or more 2D profiles', specifying the verb (create), resource (lofted solid), and distinguishing details (between two or more 2D profiles). This differentiates it from sibling tools like cst_create_extrude (single profile along path) or cst_create_brick (box).
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 implies use when a lofted solid is needed, but does not provide explicit guidance on when to use it over alternatives like extrusion or other solid creation tools. No when-not or alternative recommendations are given, which is a gap given the many sibling create tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
