uc_model_create

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

The description indicates a write operation, matching the annotation readOnlyHint=false. However, it does not disclose important behavioral traits such as idempotency, error conditions, or permission requirements, which are critical for a mutation tool with no additional annotations.

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 extremely concise (one sentence), but it lacks structure and detail. While it is front-loaded with the core action, it is underdeveloped and could benefit from additional context without becoming verbose.

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 tool's complexity (10 parameters, including optional ones) and the lack of output schema details despite 'Has output schema: true', the description is insufficient. It does not cover essential aspects like return values or parameter constraints, making it incomplete for an agent to use effectively.

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?

With schema description coverage at 40%, the description adds no parameter-specific information beyond the schema. Optional parameters like storage_root, tags, alias, and version are left unexplained, and the description does not compensate for the low coverage.

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 explicitly states the action 'Create' and the resource 'registered model' with the underlying API endpoint. It distinguishes from sibling tools like uc_model_delete and uc_model_update, though it could be more descriptive about the model registration concept.

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 such as mlflow_registered_models_create, or any prerequisites like catalog/schema existence. The description lacks context for usage decisions.

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