C2.4/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the safety profile is partly covered. However, the description adds nothing beyond that: it doesn't state whether the workspace name must be unique, whether creation requires elevated permissions, or whether the new workspace is empty on creation. For a mutating creation tool this is a notable gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One short, front-loaded sentence with no filler or redundancy. It is efficient, though its brevity stems from under-specification rather than disciplined editing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained. But for a creation/mutation tool with no annotations detailing permissions and a parameter with zero schema documentation, the description leaves an agent without the naming constraints or access requirements it needs to invoke this correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter 'name' has 0% schema description coverage, so the description is the only place semantics could be added — yet it says nothing about naming rules, uniqueness, length limits, or format. With one undocumented parameter, the description fails to compensate for the schema gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a clear verb+resource ('Create a new workspace'), but the sentence is essentially a paraphrase of the tool name and adds no distinguishing detail against siblings like workspace_create_folder, workspace_create_tag, or workspace_create_workspace's read counterparts. An agent can tell what it does, but nothing helps it choose between this and other create-style workspace tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no prerequisites (e.g., required role/permission to create a workspace), and no mention of alternatives such as creating a folder or tag inside an existing workspace. The description gives no condition that would route an agent to this tool over its siblings.

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