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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds genuinely new behavioral facts beyond the annotations: exactly which data classes are destroyed and that the workspace token is revoked, plus 'permanently' signalling irreversibility.

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?

Two tight sentences with the destructive scope front-loaded and zero filler. Every clause carries information.

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 destructive mutation with strong annotation coverage and no output schema, the description covers impact and token revocation adequately. It falls short only on the required confirmDelete guard and on any permission/auth requirement.

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 only 50%, and the undocumented parameter is the critical one: confirmDelete (required, const true) is never mentioned in the description, so the agent gets no explanation of the confirmation guard. workspaceToken is well documented in the schema, so the description adds nothing there.

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 ('Permanently delete') plus resource ('the temporary workspace') and even quantifies the blast radius (project, file and job data). An agent can distinguish this from create_workspace/get_workspace purely from the description.

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 when-to-use guidance, no prerequisites, no alternatives named. Nothing tells the agent when deletion is warranted versus, say, exporting or inspecting the workspace first, nor that the token must be obtained from create_workspace.

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