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

Annotations already declare destructiveHint=true and openWorldHint=true, so the agent knows this is an external, irreversible-side-effect action. The description adds genuinely useful behavior — the payload is sent exactly as prepared (no editing) and the confirmation token is single-use — but omits idempotency/retry semantics and what happens to the token on failure.

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?

A single front-loaded sentence with no filler; the validation precondition follows the action. It is efficient, though its extreme brevity is achieved partly by leaving the parameter set unaddressed.

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?

An output schema exists, so return values need no explanation, and the core workflow (prepare → confirm → send) is conveyed. For a destructive, externally visible operation with three undocumented parameters, however, the definition leaves idempotency behavior and failure consequences unstated.

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 all three required parameters are undocumented in the schema. The description covers confirmationToken ('one-use') and loosely implies quoteId ('prepared quote payload'), but leaves idempotencyKey — the parameter governing safe retries for a destructive send — entirely unexplained.

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 ('Sends ... quote') and adds scope: it transmits an already 'prepared quote payload' rather than composing one, which implicitly separates it from prepare_quote_send. It never names that sibling, so differentiation is inferable rather than explicit.

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?

Usage is implied by the preconditions ('exact prepared quote payload', 'one-use confirmation token'), which tell the agent it must first prepare a quote and obtain a token. There is no explicit statement of when to call this versus prepare_quote_send, nor any when-not guidance or note about retry/re-send behavior.

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