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

Annotations already declare destructiveHint=true and openWorldHint=false, so the description's added value is the disclosure that deletion is gated behind an emailed confirmation code — a required auth/verification step not visible in the annotations or schema. It still omits what happens to the account's data and whether deletion is reversible.

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, front-loaded with the destructive scope before the action mechanics. Nothing is redundant with the title or the enum listing.

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 high-stakes destructive tool with no output schema, the description covers the workflow and parameter discovery adequately, and annotations cover the safety profile. It stops short of stating consequences (data loss, irreversibility, whether the account can be restored), which an agent invoking confirm should know.

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 enum values carry no per-value text, but the description explains what send_code and confirm mean and provides a discovery path for the undocumented nested params ('call with action "help" for each action's fields'). That meaningfully compensates for the gap, though the actual param fields remain unnamed.

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 the member's Applystead account) and immediately names the mechanism's two actions, send_code and confirm. It is unambiguous against siblings like get_account or update_profile, none of which share this destructive scope.

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 makes the required sequencing explicit: send_code emails a code, confirm deletes with it, and 'help' lists each action's fields. That tells an agent which action to call first, but it offers no when-not guidance or warning about the irreversibility of confirm.

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