create_elements

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

The description discloses the dry-run default and that dry_run=false triggers actual creation, which is important. However, it does not mention potential side effects, permissions required, or error handling, leaving some behavioral aspects opaque. Since there are no annotations, this is a moderate level of transparency.

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 concise and well-structured, using all-caps for emphasis on the dry-run behavior and clearly separating the main purpose from usage notes. Every sentence contributes meaning without redundancy.

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?

The description covers the core functionality, usage guidance, and distinguishes from a sibling tool, which is sufficient for most context. It does not delve into return values, but given that an output schema exists (as indicated in context), this is not required. It could be more detailed on edge cases, but overall it is complete enough for an agent to use correctly.

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 explains element_type (by listing valid types) and dry_run (by describing its effect). It does not clarify the semantics of items (presumably the list of elements to create) or port. With 4 parameters, only half are explained, so the description adds moderate value beyond the schema.

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 that the tool creates elements of specific types (column/slab/zone/polyline/object/mesh) via Tapir, and distinguishes itself from execute_api_command for other types. It also notes the dry-run default behavior, making the purpose unmistakable.

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 provides explicit guidance on when to use this tool (for listed element types) and when to use execute_api_command for other types. It also explains the dry-run default and how to override it with dry_run=false, giving clear usage instructions. While not exhaustive, it covers the key decision points.

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