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

Adds substantial behavior beyond the annotations: the call is a no-op that returns a confirmUrl, execution is deferred to a human confirmation step, and the link expires after 30 minutes. It also explicitly warns the agent not to report completion, which directly complements destructiveHint=true without contradicting it.

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?

Four short sentences, front-loaded with the core constraint ('Nothing happens yet'), followed by the required agent action and the expiry. Nothing 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?

There is no output schema, and the description compensates by naming the returned confirmUrl and explaining what the agent must do with it. Combined with annotations covering the destructive/open-world profile, an agent has everything needed to call and handle this tool correctly.

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 quoteId and customerName are already fully documented in the schema. The description adds no extra meaning about either parameter, so the baseline 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?

The description states a specific verb and resource ('emailing a draft quote to the client') and frames it precisely as a preparation step. It does not name any sibling (e.g. send_invoice or create_quote_draft), so differentiation is left to the agent, which keeps it short of a 5.

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 clear operational guidance after the call (give the user the link, the action only runs on Confirm, never say it was done) but never states when to choose this over send_invoice or create_quote_draft, nor any prerequisite for the quote being a draft. Usage context is implied rather than scoped.

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