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

Annotations already declare the write profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false, openWorldHint=false), so the safety bar is lower, but the description adds nothing beyond them. It does not mention that repeat calls create duplicates (non-idempotent), whether the caller becomes owner, or what the response contains.

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?

One short, front-loaded sentence with zero filler. It is appropriately sized structurally, though the brevity comes at the cost of substance rather than being a model of efficient density.

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 creation tool with no output schema, the description still leaves open what is returned (workspace id?), whether duplicates are allowed, and any post-creation expectations. The mutation context is only conveyed by the tool name and annotations.

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?

There is a single required parameter with 100% schema description coverage ('Workspace name'), so the schema carries the load. The description contributes no extra meaning such as constraints on the name or whether it must be unique.

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 states a specific verb (create) and resource (workspace), so the agent can tell it apart from delete_workspace and list_workspaces by name alone. But the sentence is a near-verbatim restatement of the title, adding no distinguishing detail about what a created workspace contains or defaults to.

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 on when to use this versus add_media_from_url/set_default_workspace, no prerequisites (plan limits, name uniqueness), and no note on what to do afterwards. Usage must be entirely inferred from the tool name.

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