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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered without the description. The description adds mild value by naming the fields returned (useful since there is no output schema), but discloses nothing about auth, errors, or lookup failure behavior.

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 tight sentence with the verb and resource front-loaded and returned fields parenthesized; nothing is wasted. It is perhaps slightly too terse to be fully explanatory, which keeps it off a 5.

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 single-parameter read tool with annotations covering safety and a fully documented schema, the description is nearly sufficient: it names the resource and the returned fields, compensating for the absent output schema. It could still note the single-workspace scope versus list_workspaces, but no agent-blocking information is missing.

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?

Schema description coverage is 100% for the single workspaceId parameter, so the schema carries the semantics, including how to obtain an ID. The description contributes no additional meaning about the parameter, which is the correct baseline of 3.

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?

States a specific verb (Get) and resource (info for a workspace) and enumerates the returned fields (name, plan, subscription status), which makes the tool's scope concrete. It stops short of distinguishing itself from the sibling list_workspaces or get_workspace_models, relying on the schema's pointer instead.

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 gives no when-to-use or when-not-to-use guidance and never names an alternative. The only routing hint ('get the list from the list_workspaces tool') lives in the schema parameter description, not the tool description, so usage is left to inference.

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