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

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes the multi-step creation process (workspace, user account, credential return), which goes beyond a simple 'create' statement. However, it lacks details on permissions needed, error conditions, or rate limits that would be helpful for a mutation 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 well-structured with a clear purpose statement, numbered process steps, and organized parameter/return sections. It is appropriately sized for a complex tool, though the 'Returns' section could be more specific (e.g., what fields are included) to enhance clarity without adding bulk.

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 (6 parameters, mutation operation, no annotations, no output schema), the description does a good job covering purpose, process, and parameters. However, it lacks details on error handling, authentication requirements, or example return values, which would make it more complete for a creation tool in a multi-step environment.

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 includes an 'Args' section that clearly explains all 6 parameters (5 required, 1 optional) with meaningful semantics beyond the schema, which has 0% description coverage. For example, it clarifies that 'name' must be unique, 'database_name' is created in the workspace, and 'workspace_group' is optional configuration. This fully compensates for the schema's lack of descriptions.

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 specific action ('Create a new starter (virtual) workspace in SingleStore and set up user access'), identifies the resource (virtual workspace), and distinguishes from siblings like 'list_virtual_workspaces' or 'workspaces_info' by focusing on creation rather than listing or querying. The three-step process further clarifies the scope.

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 usage context through the process steps (e.g., when you need a new workspace with user access), but does not explicitly state when to use this tool versus alternatives like 'list_virtual_workspaces' for viewing existing ones or 'execute_sql_on_virtual_workspace' for operations on an existing workspace. No exclusions or prerequisites are mentioned.

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