create_root_model

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

With no annotations, the description carries the full burden. It discloses that it returns the root model id and name, but does not mention whether this is a destructive operation, any permission requirements, or side effects on existing model structure. For a write operation, this is a significant gap.

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 sentences, no filler, and the action is front-loaded. 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 one-parameter tool, the description covers the core function and return value. However, as a mutation with no annotations, it omits behavioral details (side effects, permissions) and assumes the agent understands what a 'root model element' is. The output schema likely provides return details, but the description's gaps lower completeness.

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 only parameter 'name' is self-explanatory from the schema (with a default of 'Model'). The description implies that this sets the new name but adds minimal value beyond the schema. Since schema coverage is 0%, the description could have clarified that 'name' is the desired root element name, but it's not essential.

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 the action (Set or rename) and the resource (root model element), which distinguishes it from siblings like rename_element that target arbitrary elements. However, it doesn't explicitly define what a 'root model element' is, leaving some ambiguity for agents unfamiliar with the domain.

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. It is implied that this is for the root element only, but the description does not explicitly say 'use rename_element for non-root elements' or mention any prerequisites or exclusions.

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