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

The annotation only declares destructiveHint=true, and the description goes well beyond it: irreversibility ('cannot be undone from the dashboard'), downstream consequences ('can no longer log in or receive calls'), and a protected-object constraint ('The owner cannot be deleted'). These are exactly the traits an agent needs before firing a destructive call.

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, each carrying distinct information: what happens, what is forbidden, and the required confirmation step. The destructive nature is front-loaded, and no sentence is redundant.

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 one-parameter destructive tool with no output schema, the description covers irreversibility, side effects, and a guardrail, which is close to sufficient. It stops short of noting permission requirements or what happens to data (leads, calls) owned by the deleted user, which would matter for a permanent account change.

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 user_id parameter is already documented as 'The user to delete (ids from get_users)', which even points at the discovery tool. With the schema doing the work and no additional semantics offered in the description, the baseline of 3 applies.

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 ('Permanently delete a user from the account') with the added qualifier 'permanently', which distinguishes it from a soft-disable. However, it never names or contrasts with the sibling 'manage_user', which plausibly overlaps in scope, so the agent must still infer the boundary.

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 instruction 'Confirm with the user first' is a genuine precondition on invocation, so this is more than nothing. But there is no guidance on when to prefer remove_user over manage_user or how it relates to delete_team, leaving alternative-selection entirely to inference.

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