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

Annotations already flag destructiveHint=true and idempotentHint=false, yet the description adds genuinely non-obvious behavior: mailboxes survive the deletion, return to 'My mailboxes', and keep warming, while the client report link breaks. It stops short of saying whether the workspace itself is recoverable or what the response returns, which is the one remaining gap for a destructive 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?

Three short sentences, front-loaded with the action and then the two consequences that matter. Nothing repeats the structured fields and no sentence is filler.

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 destructive tool with annotations covering the safety profile, the description supplies the key side effects an agent needs. Only irreversibility/recoverability and the return shape are unstated, both minor here.

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 coverage is 100% and the single parameter is documented with format ('ws_…') and provenance ('from list_workspaces'), so the schema does the heavy lifting. The description adds no parameter-level meaning, which is the correct baseline of 3 for a fully documented one-param schema.

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 and resource ('Delete a client workspace') and immediately distinguishes its semantics from the generic delete expectation. An agent can tell it apart from rename_workspace, create_workspace, and move_mailbox_to_workspace without opening any schema.

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 explains consequences but never says when to prefer this over alternatives (e.g. deleting vs. renaming vs. moving mailboxes out first), nor does it state any prerequisite such as confirmation or ownership. Usage is implied by the destructive framing rather than articulated.

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