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

The description explicitly says the account is permanently closed and the workspace and its data are deleted, which is destructive behavior. The annotations declare destructiveHint=false, directly contradicting the description's central warning.

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?

The confirmation instruction is front-loaded and every clause carries useful information about permanence, restore options, billing, and store notice handling. It is dense but appropriately sized for a destructive account operation.

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?

Given the absence of an output schema and the high schema coverage, the description covers the important operational context: confirmation, permanence, recovery, plan cancellation, store notice behavior, and authorization. The main gap is the contradiction with the destructiveness annotation rather than missing task details.

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%, so all three parameters are already documented in the schema. The description adds some operational context around confirmToken and owner-only access, but it does not meaningfully expand on workspaceName or organizationId beyond the 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?

The description states a specific verb and resource: permanently closes the account and deletes the workspace plus its keys, APIs, functions, and data. It is clearly an account-level destructive operation, though it does not explicitly differentiate itself from sibling deletion tools.

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?

It gives explicit operating conditions: ask the user to confirm the workspace name, never decide for them, and note that the caller must be the owner. It does not name alternative tools or when not to use this one, so it falls short of full when/when-not guidance.

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