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

Annotations only declare destructiveHint=true; the description adds substantial behavior beyond that: irreversibility, that the drop URL is never reassigned, asymmetric auth-dependent latency (immediate vs. human-gated), the confirmation_required response shape with an address, and the passkey/email confirmation method. This is exactly the extra context a destructive tool needs.

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 permanence warning is front-loaded in the first sentence where it matters most, and the auth/confirmation mechanics follow in a logical order with no filler. Four dense sentences are justified by the complexity, though the confirmation flow could be tightened slightly.

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?

With no output schema, the description does the right thing by describing the confirmation_required response and its address. The remaining gap is what a successful deletion returns and how to source the dropId, but for a destructive two-path tool the behavioral picture is largely complete.

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 description coverage is 0%, so the description must carry the load. It implies the role of managementToken ('with a management token it is immediate'), which helps, but it says nothing about dropId beyond the resource name — not its 8-character lowercase alphanumeric format, nor where the agent should obtain it — leaving the required parameter underspecified.

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 opens with a specific verb and resource ('Permanently delete a drop') and immediately qualifies scope with 'Final — the URL is never reassigned', which separates it from reversible siblings like dropyour_replace or dropyour_rollback. It never names a sibling delete/alternative tool explicitly (e.g. dropyour_secret_delete), so it stops short of full differentiation.

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 clearly explains the two invocation contexts: with a management token the deletion is immediate, and with a connected account or account token the agent must expect confirmation_required and call again after the human confirms. That is actionable how-to-invoke guidance. It gives no when-not-to-use guidance or comparison to alternative deletion paths, which keeps it below a 5.

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